A-10/OA-10 Thunderbolt II

Function: The A-10 and OA-10 Thunderbolt IIs are the first Air Force aircraft specially designed for close air support of ground forces. They are simple, effective and survivable twin-engine jet aircraft that can be used against all ground targets, including tanks and other armored vehicles.

History: The first production A-10A was delivered to Davis-Monthan Air Force Base, AZ, in October 1975. It was designed specially for the close air support mission and had the ability to combine large military loads, long loiter and wide combat radius, which proved to be vital assets to America and its allies during Operation Desert Storm. In the Gulf War, A-10s, with a mission capable rate of 95.7 percent, flew 8,100 sorties and launched 90 percent of the AGM-65 Maverick missiles.

Description: The A-10/OA-10 have excellent maneuverability at low air speeds and altitude, and are highly accurate weapons-delivery platforms. They can loiter near battle areas for extended periods of time and operate under 1,000-foot ceilings (303.3 meters) with 1.5-mile (2.4 kilometers) visibility. Their wide combat radius and short takeoff and landing capability permit operations in and out of locations near front lines. Using night vision goggles, A-10/ OA-10 pilots can conduct their missions during darkness.

Thunderbolt IIs have Night Vision Imaging Systems (NVIS), compatible single-seat cockpits forward of their wings and a large bubble canopy which provides pilots all-around vision. The pilots are encircled by titanium armor that also protects parts of the flight-control system. The redundant primary structural sections allow the aircraft to enjoy better survivability during close air support than did previous aircraft. The aircraft can survive direct hits from armor-piercing and high-explosive projectiles up to 23mm. Their self-sealing fuel cells are protected by internal and external foam. Their redundant hydraulic flight-control systems are backed up by manual systems. This permits pilots to fly and land when hydraulic power is lost.

The Thunderbolt II can be serviced and operated from bases with limited facilities near battle areas. Many of the aircraft's parts are interchangeable left and right, including the engines, main landing gear and vertical stabilizers.

Avionics equipment includes communications, inertial navigation systems, fire control and weapons delivery systems, target penetration aids and night vision goggles. Their weapons delivery systems include head-up displays that indicate airspeed, altitude and dive angle on the windscreen, a low altitude safety and targeting enhancement system (LASTE) which provides constantly computing impact point freefall ordnance delivery; and Pave Penny laser-tracking pods under the fuselage. The aircraft also have armament control panels, and infrared and electronic countermeasures to handle surface-to-air-missile threats.

The Thunderbolt II's 30mm GAU-8/A Gatling gun can fire 3,900 rounds a minute and can defeat an array of ground targets to include tanks. Some of their other equipment includes an inertial navigation system, electronic countermeasures, target penetration aids, self-protection systems, and AGM-65 Maverick and AIM-9 Sidewinder missiles.

AC-130H/U Gunship

Function: The AC-130 gunship's primary missions are close air support, air interdiction and force protection. Missions in close air support are troops in contact, convoy escort and urban operations. Air interdiction missions are conducted against preplanned targets or targets of opportunity. Force protection missions include air base defense and facilities defense.

History: The AC-130H's call sign is "Spectre." The AC-130U's call sign is "Spooky," and traces its history to the first operational gunship, the AC-47. The U-model is the third generation of C-130 gunships. The AC-130 gunship has a combat history dating to Vietnam. Gunships destroyed more than 10,000 trucks and were credited with many life-saving close air support missions. During Operation Urgent Fury in Grenada in 1983, AC-130s suppressed enemy air defense systems and attacked ground forces enabling the successful assault of the Point Salines Airfield via airdrop and air land of friendly forces. The AC-130 aircrew earned the Lt. Gen. William H. Tunner Award for the mission. AC-130s also had a primary role during Operation Just Cause in Panama in 1989 when they destroyed Panamanian Defense Force Headquarters and numerous command and control facilities. Aircrews earned the Mackay Trophy for the most meritorious flight of the year and the Tunner Award for their efforts. During Operation Desert Storm, AC-130s provided close air support and force protection (air base defense) for ground forces. Gunships also were used during operations Continue Hope and United Shield in Somalia, providing close air support for United Nations ground forces. More recently, gunships played a pivotal role in supporting the NATO mission in Bosnia-Herzegovina. The AC-130H provided air interdiction against key targets in the Sarajevo area. In 1997, gunships were diverted from Italy to provide combat air support for U.S. and allied ground troops during the evacuation of American noncombatants in Albania. Gunships also were part of the buildup of US forces in 1998 to convince Iraq to comply with U.N. weapons inspections.

Description: These heavily armed aircraft incorporate side-firing weapons integrated with sophisticated sensor, navigation and fire control systems to provide surgical firepower or area saturation during extended loiter periods, at night and in adverse weather. The sensor suite consists of a television sensor, infrared sensor and radar. These sensors allow the gunship to visually or electronically identify friendly ground forces and targets any place, any time. The AC-130U employs synthetic apertures strike radar for long-range target detection and identification. Navigational devices include the inertial navigation systems and global positioning system. The AC-130U employs the latest technologies and can attack two targets simultaneously.

B-1B Lancer

Function: The B-1B is a long-range strategic bomber, capable of flying intercontinental missions without refueling, then penetrating present and future sophisticated enemy defenses. It can perform a variety of missions, including that of a conventional weapons carrier for theater operations.

History: The first B-1B was delivered to the Air Force at Dyess Air Force Base, Texas, in June 1985, with initial operational capability on Oct. 1, 1986. The final B-1B was delivered May 2, 1988.

The B-1B holds several world records for speed, payload and distance. The National Aeronautic Association recognized the B-1B for completing one of the 10 most memorable record flights for 1994.

Description: The B-1B's electronic jamming equipment, infrared countermeasures, radar location and warning systems complement its low-radar cross-section and form an integrated defense system for the aircraft.

The swing-wing design and turbofan engines not only provide greater range and high speed at low levels but they also enhance the bomber's survivability. Wing sweep at the full-forward position allows a short takeoff roll and a fast base-escape profile for airfields under attack. Once airborne, the wings are positioned for maximum cruise distance or high-speed penetration.

The B-1B uses radar and inertial navigation equipment enabling aircrews to globally navigate, update mission profiles and target coordinates in-flight, and precision bomb without the need for ground-based navigation aids. Included in the B-1B offensive avionics are modular electronics that allow maintenance personnel to precisely identify technical difficulties and replace avionics components in a fast, efficient manner on the ground.

The aircraft's AN/ALQ 161A defensive avionics is a comprehensive electronic counter-measures package that detects and counters enemy radar threats. It also has the capability to detect and counter missiles attacking from the rear. It defends the aircraft by applying the appropriate counter-measures, such as electronic jamming or dispensing expendable chaff and flares. Similar to the offensive avionics, the defensive suite has a re-programmable design that allows in-flight changes to be made to counter new or changing threats.

Numerous sustainment and upgrade modifications are ongoing or under study for the B-1B aircraft. Large portions of these modifications that are designed to increase the combat capability are known as the conventional mission upgrade program. This three-phase program will increase the lethality, survivability and supportability of the B-1B fleet. Phase I of the program added the capability to release cluster bomb unit weapons. Phases II and III will further upgrade the B-1B capability, to include the ability to deliver joint direct attack munitions and standoff weapons, and greatly improve its electronic counter-measures capability.

B-2 Spirit

Function: The B-2 Spirit is a multi-role bomber capable of delivering both conventional and nuclear munitions. A dramatic leap forward in technology, the bomber represents a major milestone in the U.S. bomber modernization program. The B-2 brings massive firepower to bear, in a short time, anywhere on the globe through previously impenetrable defenses.

History: The first B-2 was publicly displayed on Nov. 22, 1988, when it was rolled out of its hangar at Air Force Plant 42, Palmdale, CA. Its first flight was July 17, 1989. The B-2 Combined Test Force, Air Force Flight Test Center, Edwards Air Force Base, CA, is responsible for flight testing the engineering, manufacturing and development aircraft as they are produced.

Whiteman AFB, MO, is the B-2's only operational base. The first aircraft, Spirit of Missouri, was delivered Dec. 17, 1993. Depot maintenance responsibility for the B-2 is performed by Air Force contractor support and is managed at the Oklahoma City Air Logistics Center at Tinker AFB, Okla.

The prime contractor responsible for overall system design and integration,is Northrop Grumman's Military Aircraft Systems Division. Boeing Military Airplanes Co., Hughes Radar Systems Group and General Electric Aircraft Engine Group are key members of the aircraft contractor team. Another major contractor, responsible for aircrew training devices (weapon system trainer and mission trainer) is Hughes Training Inc. (HTI) - Link Division, formerly known as CAE - Link Flight Simulation Corp. Northrop Grumman and its major subcontractor HTI, are responsible for developing and integrating all aircrew and maintenance training programs.

Description: Along with the B-52 and B-1B, the B-2 provides the penetrating flexibility and effectiveness inherent in manned bombers. Its low-observable, or "stealth," characteristics give it the unique ability to penetrate an enemy's most sophisticated defenses and threaten its most valued, and heavily defended, targets. Its capability to penetrate air defenses and threaten effective retaliation provide a strong, effective deterrent and combat force well into the 21st century.

The revolutionary blending of low-observable technologies with high aerodynamic efficiency and large payload gives the B-2 important advantages over existing bombers. Its low-observability provides it greater freedom of action at high altitudes, thus increasing its range and a better field of view for the aircraft's sensors. Its unrefueled range is approximately 6,000 nautical miles (9,600 kilometers).

The B-2's low observability is derived from a combination of reduced infrared, acoustic, electromagnetic, visual and radar signatures. These signatures make it difficult for the sophisticated defensive systems to detect, track and engage the B-2. Many aspects of the low-observability process remain classified; however, the B-2's composite materials, special coatings and flying-wing design all contribute to its "stealthiness."

The B-2 has a crew of two pilots, a pilot in the left seat and mission commander in the right, compared to the B-1B's crew of four and the B-52's crew of five.

B-52 Stratofortress

Function: Long range, nuclear capable strategic bomber

History: For more than 35 years B-52 Stratofortresses have been the primary manned strategic bomber force for the United States. The B-52 is capable of dropping or launching the widest array of weapons in the U.S. inventory. This includes gravity bombs, cluster bombs and precision guided missiles. Updated with modern technology, the B-52 will continue into the 21st century as an important element of our nation's defenses. Current engineering analyses show the B-52's life span to extend beyond the year 2045.

The B-52A first flew in 1954, and the B model entered service in 1955. A total of 744 B-52s were built with the last, a B-52H, delivered in October 1962. Only the H model is still in the Air Force inventory and is assigned to Air Combat Command and the Air Force Reserves.

The first of 102 B-52Hs was delivered to Strategic Air Command in May 1961. The H model can carry up to 20 air launched cruise missiles. In addition, it can carry the conventional cruise missile that was launched from B-52G models during Desert Storm.

Description: In a conventional conflict, the B-52 can perform air interdiction, offensive counter-air and maritime operations. During Desert Storm, B-52s delivered 40 percent of all the weapons dropped by coalition forces. It is highly effective when used for ocean surveillance, and can assist the U.S. Navy in anti-ship and mine-laying operations. Two B-52s, in two hours, can monitor 140,000 square miles (364,000 square kilometers) of ocean surface. All B-52s are equipped with an electro-optical viewing system that uses platinum silicide forward-looking infrared and high resolution low-light-level television sensors to augment the targeting, battle assessment, flight safety and terrain-avoidance system, thus further improving its combat ability and low-level flight capability. Pilots wear night vision goggles (NVGs) to enhance their night visual, low-level terrain-avoidance operations. Night vision goggles provide greater safety during night operations by increasing the pilot's ability to visually clear terrain and avoid enemy radar. Starting in 1989, an on-going modification incorporates the global positioning system, heavy stores adapter beams for carrying 2,000 pound munitions and additional smart weapons capability.

The use of aerial refueling gives the B-52 a range limited only by crew endurance. It has an unrefueled combat range in excess of 8,800 miles (14,080 kilometers).

The aircraft's flexibility was evident during the Vietnam War and, again, in Operation Desert Storm. B-52s struck wide-area troop concentrations, fixed installations and bunkers, and decimated the morale of Iraq's Republican Guard. The Gulf War involved the longest strike mission in the history of aerial warfare when B-52s took off from Barksdale Air Force Base, LA, launched conventional air launched cruise missiles and returned to Barksdale -- a 35-hour, non-stop combat mission.

P-3C Orion

Function: Four-engine turboprop anti-submarine and maritime surveillance aircraft.

History: In February 1959, the Navy awarded Lockheed a contract to develop a replacement for the aging P2V Neptune. The P3V Orion, derived from Lockheed's successful L188 Electra airliner, entered the inventory in July 1962, and more than 30 years later it remains the Navy's sole land-based antisubmarine warfare aircraft. It has gone through one designation change (P3V to P-3) and three major models: P-3A, P-3B, and P-3C, the latter being the only one now in active service. The last Navy P-3 came off the production line at the Lockheed plant in April 1990.

Description: The P-3C is a land-based, long-range, anti-submarine warfare (ASW) patrol aircraft. It has advanced submarine detection sensors such as directional frequency and ranging (DIFAR) sonobuoys and magnetic anomaly detection (MAD) equipment. The avionics system is integrated by a general purpose digital computer that supports all of the tactical displays, monitors and automatically launches ordnance and provides flight information to the pilots. In addition, the system coordinates navigation information and accepts sensor data inputs for tactical display and storage. The P-3C can carry a mixed payload of weapons internally and on wing pylons.

S-3B Viking

Function: Jet aircraft is used in the detection and attack of submarines, and as an armed scout in the anti-surface role. Extremely versatile, the aircraft is also equipped for tanking, mining, and limited electronic surveillance.

Description: Modified from the earlier S-3A Viking, the S-3B's high speed computer system processes information generated by the acoustic and non-acoustic target sensor systems. This includes a new Inverse Synthetic Aperture Radar (ISAR) and ESM systems suites. To destroy targets, the S-3B Viking employs an impressive array of airborne weaponry. This provides the fleet with a very effective airborne capability to combat the significant threat presented by modern combatants and submarines. Additionally, all S-3B aircraft are capable of carrying an inflight refueling "buddy" store. This allows the transfer of fuel from the Viking aircraft to other Naval strike aircraft, thus extending their combat radius.

CH-47 Chinook

Function: Fire support and security for forward and rear area forces, point target/anti-armor, anti-helicopter, armed escort, supporting arms control and coordination, point and limited area air defense from enemy fixed-wing aircraft, armed and visual reconnaissance.

History: Development of the medium lift Boeing Vertol (models 114 and 414) CH-47 Series Chinook began in 1956. Since then the effectiveness of the Chinook has been continually upgraded by successive product improvements, the CH-47A, CH-47B, CH-47C, and CH-47D. The amount of load a cargo helicopter can carry depends on the model, the fuel on board, the distance to be flown, and atmospheric conditions.

The CH-47B was introduced by Boeing after a production run of over 350 CH-47A痴 . The B model introduced the Lycoming T55-L7C engine, a beefed up airframe. Nonsymmetrical rotor blades, and the blunted aft pylon for better stability. Boeing began delivering the CH-47B in May of 1967 and eventually produced a total of 108 B models before production shifted to the CH-47C.

During Desert Storm the CH-47D was often the only mode of transportation to shift large numbers of personnel, equipment, and supplies rapidly over the vast area in which US forces operated. The cargo capacity and speed provided commanders and logisticians a capability unequalled by any Army in the world." (Army Aviation in Operation Desert Storm, 1991) During the ground phase, the flanking maneuver executed by the XVIII Airborne Corps was planned with the CH-47D as the keystone. Forward Operating Base Cobra was deliberately positioned to accommodate the combat radius of a fully loaded CH-47D. Cobra was initially secured by an air assault of the 101st's 2nd Infantry Brigade. This air assault, consisting of 5000 soldiers, was accomplished by a total of 126 Blackhawks and 60 Chinooks. By the end of the first day the CH-47Ds had lifted 131,000 gallons of fuel along with pallets of combat-configured ammunition for the next day's fight. Forty separate refueling and rearming points were active in FOB Cobra in less than two hours.

During peacekeeping operations in Bosnia, a Chinook company (A company, 5th Battalion, 159th Aviation Regiment) of 16 aircraft flew 2,222 hours, carried 3,348 passengers, and transported over 3.2 million pounds of cargo over a six month period. These numbers equate to carrying 112 infantry platoons, 545 HMMWVs, or 201 M198 Howitzers. The most publicized mission was assisting the 502d Engineer Company build a float bridge across the flooded Sava River allowing the 1st Armored Division to cross into Bosnia. On 29 and 30 December 1995, Big Windy lifted bridge bays and dropped them into the Sava River so the engineers could quickly assemble the bridge. When the Sava River flood washed away the engineer's tentage and personal equipment, Big Windy quickly resupplied the engineers so they could continue their vital mission. Additionally, a key early mission in support of NATO was the recovery of Admiral Smith's aircraft. The Blackhawk had performed a precautionary landing for what was later found to be a transmission seizure. A CH-47D sling-loaded the Blackhawk back to the Intermediate Staging Base (ISB). Big Windy began redeploying to Giebelstadt on 14 June 1996. One platoon of six CH-47Ds remained in Hungary throughout 1997.

Description: The CH-47 is a twin-engine, tandem rotor helicopter designed for transportation of cargo, troops, and weapons during day, night, visual, and instrument conditions. The aircraft fuselage is approximately 50 feet long. With a 60-foot rotor span, on each rotor system, the effective length of a CH-47 (with blades turning) is approximately 100 feet from the most forward point of the forward rotor to the most rearward point on the aft rotor. Maximum airspeed is 170 knots with a normal cruise speed of 130 knots. However, speed for any mission will vary greatly depending on load configuration (internal or external), time of day, or weather conditions. The minimum crew for tactical operations is four, two pilots, one flight engineer, and one crew chief. For more complex missions, such as NVG operations and air assaults, commanders may consider using five crew members and add one additional crew chief.

The CH-47A, first delivered for use in Vietnam in 1962, is a tandem-rotor medium transport helicopter. The Chinook's primary mission is moving artillery, ammunition, personnel, amd supplies on the battlefield. It also performs rescue, aeromedical, parachuting, aircraft recovery and special operations missions. On June 25, 1958 the Army issued an invitation for a General Management Proposal for the US Army Medium Transport Helicopter. Five aircraft selected Vertol to produce the YCH-1B as the Army痴 new medium transport helicopter. In July 1962 DoD redesignated all U.S. military aircraft and the HC-1B was redesignated the as the CH-47A. Early production CH-47A痴 operated with the 11th Air Assault Division during 1963 and in October of that year the aircraft was formally designated as the Army痴 standard medium transport helicopter. In June 1965 the 11th Air Assault Division was redesignated as the 1st Cavalry Division (Airmobile) and readied for deployment to Viet Nam. Chinooks from the 11th Air Assault formed the nucleus of the 228th Assault Helicopter Battalion which began operations in Viet Nam in September, 1965. CH-47A痴 deployed to Viet Nam were equipped with Lycoming T55-L7 engines generating 2650 shp. The aircraft had a maximum gross weight of 33,000 pounds allowing for a maximum payload of approximately 10,000 pounds. The hot mountainous conditions of Viet Nam limited the A models performance capabilities and generated a requirement for increased payload and better performance.

The CH-47C Chinook model has a maximum cargo hook capacity of 20,000 pounds. The CH-47C has only a single cargo hook below the center of the aircraft. When hooking a single load, soldiers use the main hook. They must coordinate closely with the aircrew as to which hooks to use when carrying multiple loads. The planning figure for the fore and aft hooks is 10,000 pounds each. The Army痴 continued need for further performance improvements lead to the development of the CH-47C. Designed to meet an Army requirement to transport a 15,000 pound sling load over a 30 mile radius, the C model boasted an increased gross weight to 46,000 pounds, increased fuel capacity, the Lycoming T55-L11 engine developing 3750 shp, and addition structural improvements. The first C model flew in late 1967 and became the mainstay of the Chinook fleet until the advent of the CH-47D. Production of the C model continued until 1980 with improvements such as the crash worthy fuel system and fiberglass rotor blades being incorporated into the fleet.

The CH-47D was the result of June 1976 contract for a modernized Chinook. The Army recognized that that the Chinook fleet was rapidly reaching the end of its useful life and signed a contract with Boeing to significantly improve and update the CH-47. Three airframes, CH-47A, CH-47B, and a CH-47C, were stripped down to their basic airframes and then rebuilt with improved systems to provide three CH-47D prototypes. Improvements included upgraded power plants, rotor transmissions, integral lubrication and cooling for the transmission systems, and fiberglass rotor blades. Other improvements included a redesigned cockpit to reduce pilot workload, redundant and improved electrical systems, modularized hydraulic systems, an advanced flight control system, and improved avionics. The Chinook has two tandem three-bladed counter-rotating fiberglass rotors. The CH-47D is powered by two Allied Signal Engines T55-L-712 3750 shp turboshaft engines and has a maximun speed of 163 mph (142 knots). The CH-47D was rolled-out in March 1979. The CH-47D carrys twice the load of a CH-47A and has improved performance. The CH-47D can operate at night and in nearly all weather conditions. The CH-47D is equipped with an air-to-air refueling probe. The Chinook can accommodate a wide variety of internal payloads, including vehicles, artillery pieces, 33 to 44 troops, or 24 litters plus two medical attendants. The Chinook can be equipped with two door mounting M60D 7.62mm machine guns on the M24 armament subsystem and a ramp mounting M60D using the M41 armament subsystem. The "D" model can carry up to 26,000 pounds externally. The CH-47D has three cargo hooks: a center (main) hook and two additional hooks fore and aft of the main hook.

The Fatcow is a CH-47 with the Extended Range Fuel System [ERFS] II system located in the cargo bay. The configuration consists of three or four fuel tanks attached to a refueling system. The system contains 2400 gallons of JP4/8 excluding the CH-47 internal fuel load of 1050 gals. The Fatcow can set up a 1,2,3,or 4 point system using HTARS. The fuel cells must be crash-worthy and self sealing up to 50 caliber hits.

The Improved Cargo Helicopter (ICH) is a remanufactured version of the CH-47D Chinook cargo helicopter with the new T55-GA-714A engines. The ICH program is intended to restore CH-47D airframes to their original condition and extend the aircraft's life expectancy another 20 years (total life of 60 years) until the 2025-2030 timeframe. The program will remanufacture CH-47 aircraft, reduce the aircraft's vibration, thereby reducing Operations and Support costs, and allow the aircraft to operate on the digitized battlefield by incorporating a 1553 data bus. The ICH will also acquire the capability to carry 16,000 pounds of external/internal cargo for a 50 NM combat radius at 4000 feet pressure altitude and 95 degrees fahrenheit. In addition, the following improvements will be incorporated into the aircraft:

- Fuselage stiffening and possible active systems for vibration reduction (this is expected to lead to improved reliability and therefore reduced operating and support costs)
- Integrated cockpit
- Digital architecture for Force XXI compatibility

Additional improvements may be incorporated into the aircraft if funding permits. The ICH will transport weapons, ammunition, equipment, troops, and other cargo in general support of combat units and operations other than war. The ICH is a dominant maneuver platform that provides focused logistics to the force. The ICH program was built as a "bare bones" program to satisfy the battlefield requirements of operations on the 21st century digital battlefield by replacing the existing 1970s technology cockpit with a new cockpit.

The 101st Air Assault Division is scheduled to receive the first ICH in FY03. The First Unit Equipped (FUE) date to the 101st, a company of sixteen aircraft, is FY04. The 101st, 18th Airborne Corps, Korea, and USAREUR will complete fielding through FY09. ICH completes the fielding of 300 aircraft in 2015. Only 300 of the 431 CH-47Ds convert to ICHs based on the fielding of JTR. As the Army fields JTR to Force Package One units, the ICH aircraft will cascade to units that retained CH-47Ds. Those CH-47Ds would retire.

Separate programmatically from the ICH program, the 714 engine program is an Engineering Change Proposal (ECP) to convert the present T-55-712 engines to a T-55-714 engine. This buys back performance on high/hot days lost over time by the addition of weight through modification work order enhancements. Specifically, it will provide an increased lift capability allowing the CH-47 to transport 16,000 pounds for an unrefueled combat radius of 50 nautical miles at 4,000 feet PA and 95 degrees F. The ICH Operational Requirements Document (ORD) requires the CH-47F(ICH) to carry 16,000lbs at 4000ft/95・ for a 50nm combat radius (50nm with load, return empty). The CH-47D -714A engine program achieves this requirement. The -714A engine program converts current CH-47D -712 engines to -714A engines. The engine program converts the engines on all 431 CH-47D aircraft. The -714A engine begins fielding in FY99 and, because of recent budget cuts, completes in FY09. 160th (Hunter), 101st, 18th AB Corps, Korea, and Germany are scheduled to be fielded through FY05. The -714A budget constantly fluctuates because of plus-ups and decrements. For this reason, the fielding dates may change.

The MH-47E Special Operations Aircraft (SOA) is a derivative of the Boeing CH-47 Chinook. Included with other modifications is a significantly increased fuel capacity with modified main and auxiliary fuel tanks. The aircraft has modified integrated avionics suites and multi-mode radars and is intended to provide adverse-weather infiltration/exfiltration and support to US Military Forces, country teams, other agencies and special activities. The CH-47D Chinook has been specially modified to perform the special operations mission and has been tested in combat. The three versions of the CH-47 in the Army inventory are the CH-47D, the MH-47D, and the MH-47E. The MH-47D and the MH-47E are air refuelable. It provides long-range penetration, medium assault helicopter support to special operations forces. Depending on the version, it can be ferried 1,100 to 2,000 nautical miles unrefueled. During Operation Just Cause, CH-47s conducted H-hour assaults to support other elements who were air-landing SOF to disrupt enemy responses and seize key facilities. During Operation Desert Storm, the CH-47 conducted infiltration and exfiltration of SOF and CSAR of downed pilots. MH-47E testing was limited to the major change to the aircraft which affects vulnerability. In the case of the MH-47E, this was the addition of an 800 gallon Robertson Auxiliary Fuel Tank in the cabin and Boeing designed sponson tanks with expanded capacity and honeycomb shell construction. Analyses conducted during the test planning phase revealed that the largest potential vulnerability was associated with projectiles entering the fuel tanks in the volume above the liquid fuel. Such impacts could ignite the fuel vapors and cause explosions and/or fires with serious consequences. During test planning, USSOCOM decided to add an inerting system to the fuel tanks to avoid such fires/explosions. This will be a lead-the-fleet system that will be available for similar helicopter variants in other fleets as well.

RAH-66 Comanche

Function: Fire support and security for forward and rear area forces, point target/anti-armor, anti-helicopter, armed escort, supporting arms control and coordination, point and limited area air defense from enemy fixed-wing aircraft, armed and visual reconnaissance.

Description: The Boeing-Sikorsky RAH-66 Comanche is the Army's next generation armed reconnaissance helicopter. It also is the first helicopter developed specifically for this role. The Comanche will provide Army Aviation the opportunity to move into the 21st century with a weapon system of unsurpassed warfighting capabilities crucial to the Army's future strategic vision. The Comanche is intended to replace the current fleet of AH-1 and OH-58 helicopters in all air cavalry troops and light division attack helicopter battalions, and supplement the AH-64 Apache in heavy division/corps attack helicopter battalions.

The first Boeing-Sikorsky RAH-66 Comanche prototype was rolled-out at Sikorsky Aircraft, Stratford, Connecticut, May 25, 1995. The prototype's first flight was made on 04 January 1996. The second prototype is scheduled to fly in late March 1999. Six early operational capability aircraft are scheduled to be delivered 2002 to participate in an Army field exercise in 2002-2003, or possibly later in "Corps 04." The Comanche is powered by two Light Helicopter Turbine Engine Co. (LHTEC) T800-801 engines. These advanced engines and a streamlined airframe will be enable the Comanche to fly significantly faster than the larger AH-64 Apache.

The RAH-66 Comanche helicopter's primary role will be to seek out enemy forces and designate targets for the AH-64 Apache Attack helicopter at night, in adverse weather, and in battlefield obscurants, using advanced infrared sensors. The helmet has FLIR images and overlaid symbology that can be used as a headup display in nape-of-the-earth (NOE) flight.

The aircraft has been designed to emit a low-radar signature (stealth features). The Comanche will perform the attack mission itself for the Army's light divisions. The RAH-66 will be used as a scout and attack helicopter to include an air-to-ground and air-to-air combat capability. The Comanche is slated to replace the AH-1 Series Cobra light attack helicopter, the OH-6A Cayuse, and the OH-58A/OH-58C Kiowa light observation helicopters.

The Comanche mission equipment package consists of a turret-mounted cannon, night-vision pilotage system, helmet-mounted display, electro-optical target acquisition and designation system, aided target recognition, and integrated communication/navigation/identification avionics system. Targeting includes a second generation forward-looking infrared (FLIR) sensor, a low-light-level television, a laser range finder and designator, and the Apache Longbow millimeter wave radar system. Digital sensors, computers and software will enable the aircraft to track and recognize advesarys long before they are aware of the Comanche's presence, a key advantage in both the reconnaissance and attack roles.

Aided target detection and classification software will automatically scan the battlefield, identifying and prioritizing targets. The target acquisition and communications system will allow burst transmissions of data to other aircraft and command and control systems. Digital communications links will enable the crew unparalleled situational awareness, making the Comanche an integral component of the digital battlefield. The armament subsystems consist of the XM301 20mm cannon, and up to 14 Hellfire anti-tank missiles, 28 Air-to-Air Stinger (ATAS) anti-aircraft missiles, or 56 2.75 inch Hydra 70 air-to-ground rockets carried internally and externally. Up to four Hellfire and two Air-to-Air Stinger (ATAS) missiles can be stowed in fully-retractable weapons bays and the gun can be rotated to a stowed position when not in use. This design feature reduces both drag and radar signature.

Mission management, status, and control information is provided over the MIL-STD-1553B databus between the mission equipment packages and the Turreted Gun System. The Comanche will have enhanced maintainability through it's modular electronics architecture and built-in diagnostics.

Features:

Sensors and avionics. In the reconnaissance role, the Comanche will be equipped with a new generation of passive sensors and a fully integrated suite of displays and communications. Advance infrared (IR) sensors will have twice the range of OH-58D Kiowa Warrior and AH-64 Apache sensors. The Comanche will be equipped with the Apache Longbow fire control radar and the Helmet Integrated Display and Sight System (HIDSS). The fully integrated avionics system will allow tactical data to be overlaid onto a digital map, allowing the crew to devote more time for target detection and classification. A triple-redundant fly-by-wire system can automatically hold the helicopter in hover or in almost any other maneuver, reducing workload, allowing the pilot to concentrate on navigation and threat avoidance. A hand-on grip permits one-handed operation.

Stealth characteristics. The Comanche incorporates more low-observable stealth features than any aircraft in Army history. The Comanche radar cross-section (RCS) is less than that of a Hellfire missile. To reduce radar cross-section, weapons can be carried internally, the gun can be rotated aft and stowed within a fairing behind the turret when not in use, and the landing gear are fully-retractable. The all-composite fuselage sides are flat and canted and rounded surfaces are avoided by use of faceted turret and engine covers. The Comanche's head-on RCS is 360 times smaller than the AH-64 Apache, 250 times less than the smaller OH-58D Kiowa Warrior, and 32 times smaller than the OH-58D's mast-mounted sight. This means the Comanche will be able to approach five times closer to an enemy radar than an Apache, or four times closer than an OH-58D, without being detected.

Noise suppression. The Comanche only radiates one-half the rotor noise of current helicopters. Noise is reduced by use of a five-bladed rotor, pioneered by the successful Boeing (McDonnell Douglas) MD-500 Defender series of light utility helicopters. The fantail eliminates interaction between main rotor and tail rotor wakes. The advanced rotor design permits operation at low speed, allowing the Comanche to sneak 40% closer to a target than an Apache, without being detected by an acoustical system.

Infrared (IR) suppression. The Comanche only radiates 25% of the engine heat of current helicopters, a critical survivability design concern in a low-flying tactical scout helicopter. The Comanche is the first helicopter in which the infrared (IR) suppression system is integrated into the airframe. This innovative Sikorsky design feature provides IR suppressors that are built into the tail-boom, providing ample length for complete and efficient mixing of engine exhaust and cooling air flowing through inlets above the tail. The mixed exhaust is discharged through slots built into an inverted shelf on the sides of the tail-boom. The gases are cooled so thoroughly that a heat-seeking missile cannot find and lock-on to the Comanche.

Crew Protection. The Comanche features a crew compartment sealed for protection against chemical or biological threats, an airframe resilient against ballistic damage, enhanced crash-worthiness, and reduced susceptibility to electromagnetic interference.

Maintainability. Comanche will be easily sustained, will require fewer personnel and support equipment, and will provide a decisive battlefield capability in day, night and adverse weather operations. Comanche has been designed to be exceptionally maintainable and easily transportable. Through its keel-beam construction, numerous access panels, easily accessible line-replaceable units/modules and advanced diagnostics, the RAH-66 possesses "designed-in" maintainability. Comanche aircraft will be able to be rapidly loaded into or unloaded from any Air Force transport aircraft.

AH-64 Apache

Function: Fire support and security for forward and rear area forces, point target/anti-armor, anti-helicopter, armed escort, supporting arms control and coordination, point and limited area air defense from enemy fixed-wing aircraft, armed and visual reconnaissance.

History: Apache production began in 1982 and the first unit was deployed in 1986. As of November 1993, 807 Apaches were delivered to the Army. The last Army Apache delivery is scheduled for December 1995. Thirty-three attack battalions are deployed and ready for combat. The Army is procuring a total of 824 Apaches to support a new force structure of 25 battalions with 24 Apaches for each unit (16 Active; two Reserve; seven National Guard) under the Aviation Restructure Initiative. The Apache has been sold to Israel, Egypt, Saudi Arabia, the UAE, and Greece.

Description: The Boeing (McDonnell Douglas) (formerly Hughes) AH-64A Apache is the Army's primary attack helicopter. It is a quick-reacting, airborne weapon system that can fight close and deep to destroy, disrupt, or delay enemy forces. The Apache is designed to fight and survive during the day, night, and in adverse weather throughout the world. The principal mission of the Apache is the destruction of high-value targets with the HELLFIRE missile. It is also capable of employing a 30MM M230 chain gun and Hydra 70 (2.75 inch) rockets that are lethal against a wide variety of targets. The Apache has a full range of aircraft survivability equipment and has the ability to withstand hits from rounds up to 23MM in critical areas.

The AH-64 Apache is a twin-engine, four bladed, multi-mission attack helicopter designed as a highly stable aerial weapons-delivery platform. It is designed to fight and survive during the day, night, and in adverse weather throughout the world. With a tandem-seated crew consisting of the pilot, located in the rear cockpit position and the co-pilot gunner (CPG), located in the front position, the Apache is self-deployable, highly survivable and delivers a lethal array of battlefield armaments. The Apache features a Target Acquisition Designation Sight (TADS) and a Pilot Night Vision Sensor (PNVS) which enables the crew to navigate and conduct precision attacks in day, night and adverse weather conditions. The Apache can carry up to 16 Hellfire laser designated missiles. With a range of over 8000 meters, the Hellfire is used primarily for the destruction of tanks, armored vehicles and other hard material targets. The Apache can also deliver 76, 2.75" folding fin aerial rockets for use against enemy personnel, light armor vehicles and other soft-skinned targets. Rounding out the Apache痴 deadly punch are 1,200 rounds of ammunition for its Area Weapons System (AWS), 30MM Automatic Gun.

Powered by two General Electric gas turbine engines rated at 1890 shaft horsepower each, the Apache痴 maximum gross weight is 17,650 pounds which allows for a cruise airspeed of 145 miles per hour and a flight endurance of over three hours. The AH-64 can be configured with an external 230-gallon fuel tank to extend its range on attack missions, or it can be configured with up to four 230-gallon fuel tanks for ferrying/self-deployment missions. The combat radius of the AH-64 is approximately 150 kilometers. The combat radius with one external 230-gallon fuel tank installed is approximately 300 kilometers [radii are temperature, PA, fuel burn rate and airspeed dependent]. The AH-64 is air transportable in the C-5, C-141 and C-17.

An on-board video recorder has the capability of recording up to 72 minutes of either the pilot or CPG selected video. It is an invaluable tool for damage assessment and reconnaissance. The Apache's navigation equipment consists of a doppler navigation system, and most aircraft are equipped with a GPS receiver.

The Apache has state-of-the-art optics that provide the capability to select from three different target acquisition sensors. These sensors are

- Day TV. Views images during day and low light levels, black and white.
- TADS FLIR. Views thermal images, real world and magnified, during day, night and adverse weather.
- DVO. Views real world, full color, and magnified images during daylight and dusk conditions.

The Apache has four articulating weapons pylons, two on either side of the aircraft, on which weapons or external fuel tanks can be mounted. The aircraft has a LRF/D. This is used to designate for the Hellfire missile system as well as provide range to target information for the fire control computer's calculations of ballistic solutions.

Threat identification through the FLIR system is extremely difficult. Although the AH-64 crew can easily find the heat signature of a vehicle, it may not be able to determine friend or foe. Forward looking infrared detects the difference in the emission of heat in objects. On a hot day, the ground may reflect or emit more heat than the suspected target. In this case, the environment will be "hot" and the target will be "cool." As the air cools at night, the target may lose or emit heat at a lower rate than the surrounding environment. At some point the emission of heat from both the target and the surrounding environment may be equal. This is IR crossover and makes target acquisition/detection difficult to impossible. IR crossover occurs most often when the environment is wet. This is because the water in the air creates a buffer in the emissivity of objects. This limitation is present in all systems that use FLIR for target acquisition.

Low cloud ceilings may not allow the Hellfire seeker enough time to lock onto its target or may cause it to break lock after acquisition. At extended ranges, the pilot may have to consider the ceiling to allow time for the seeker to steer the weapon onto the target. Pilot night vision sensor cannot detect wires or other small obstacles.

Overwater operations severely degrade navigation systems not upgraded with embedded GPS. Although fully capable of operating in marginal weather, attack helicopter capabilities are seriously degraded in conditions below a 500-foot ceiling and visibility less than 3 km. Because of the Hellfire missile's trajectory, ceilings below 500 feet require the attack aircraft to get too close to the intended target to avoid missile loss. Below 3 km visibility, the attack aircraft is vulnerable to enemy ADA systems. Some obscurants can prevent the laser energy from reaching the target; they can also hide the target from the incoming munitions seeker. Dust, haze, rain, snow and other particulate matter may limit visibility and affect sensors. The Hellfire remote designating crew may offset a maximum of 60 degrees from the gun to target line and must not position their aircraft within a +30-degree safety fan from the firing aircraft.

The Apache fully exploits the vertical dimension of the battlefield. Aggressive terrain flight techniques allow the commander to rapidly place the ATKHB at the decisive place at the optimum time. Typically, the area of operations for Apache is the entire corps or divisional sector. Attack helicopters move across the battlefield at speeds in excess of 3 kilometers per minute. Typical planning airspeeds are 100 to 120 knots during daylight and 80 to 100 knots at night. Speeds during marginal weather are reduced commensurate with prevailing conditions. The Apache can attack targets up to 150 km across the FLOT. If greater depth is required, the addition of ERFS tanks can further extend the AH-64's range with a corresponding reduction in Hellfire missile carrying capacity (four fewer Hellfire missiles for each ERFS tank installed).

The Russian-developed Mi-24 HIND is the Apache's closest couterpart. The Russians have deployed significant numbers of HINDs in Europe and have exported the HIND to many third world countries. The Russians have also developed the KA-50 HOKUM as their next generation attack helicopter. The Italian A-129 Mangusta is the nearest NATO counterpart to the Apache. The Germans and French are co-developing the PAH-2 Tiger attack helicopter, which has many of the capabilities of the Apache.

The AH-64A: The AH-64 fleet consists of two aircraft models, the AH-64A and the newer Longbow Apache (LBA), AH-64D. AH-64A model full-scale production began in 1983 and now over 800 aircraft have been delivered to the U.S. Army and other NATO Allies. The U.S. Army plans to remanufacture its entire AH-64A Apache fleet to the AH-64D configuration over the next decade. The AH-64A fleet exceeded one million flight hours in 1997, and the median age of today's fleet is 9 years and 1,300 flight hours.

The AH-64A proved its capabilities in action during both Operation Restore Hope and Operation Desert Storm. Apache helicopters played a key role in the 1989 action in Panama, where much of its activity was at night, when the AH-64's advanced sensors and sighting systems were effective against Panamanian government forces.

Apache helicopters also played a major role in the liberation of Kuwait. On 20 November 1990, the 11th Aviation Brigade was alerted for deployment to Southwest Asia from Storck Barracks in Illesheim Germany. The first elements arrived in theater 24 November 1990. By 15 January 1991 the unit had moved 147 helicopters, 325 vehicles and 1,476 soldiers to the region. The Apache helicopters of the Brigade destroyed more than 245 enemy vehicles with no losses.

During Operation Desert Storm, AH-64s were credited with destroying more than 500 tanks plus hundreds of additional armored personnel carriers, trucks and other vehicles. They also were used to destroy vital early warning radar sites, an action that opened the U.N. coalition's battle plan. Apaches also demonstrated the ability to perform when called upon, logging thousands of combat hours at readiness rates in excess of 85 percent during the Gulf War.

While recovery was ongoing, additional elements of the 11th Aviation Brigade began the next chapter of involvement in the region. On 24 April 1991 the 6th Squadron, 6th Cavalry痴 18 AH-64 helicopters began a self-deployment to Southwest Asia. The Squadron provided aerial security to a 3,000 square kilometer region in Northern Iraq as part of the Combined Task Force of Operation Provide Comfort.

And the AH-64A Apache helped to keep the peace in Bosnia. April of 1996 saw the beginning of the 11th Regiment痴 involvement in Bosnia-Herzegovina. Elements of 6-6 Cavalry served as a part of Task Force Eagle under 1st Armored Division for 7 months. In October of 1996, Task Force 11, consisting of the Regimental Headquarters, 2-6 Cavalry, 2-1 Aviation and 7-159 Aviation (AVIM) deployed to Bosnia-Herzegovina in support of Operation Joint Endeavor/Operation Joint Guard for eight months. In June of 1998 the Regimental Headquarters, 6-6 Cav and elements of 5-158 Aviation were again deployed to Bosnia-Herzegovina in support of Operations Joint Guard and Joint Forge for 5 months. The AH-64A痴 advanced sensors and sighting systems proved effective in removing the cover of darkness from anti-government forces.

Army National Guard units in North and South Carolina, Florida, Texas, Arizona, Utah and Idaho also fly Apache helicopters. The Army has fielded combat-ready AH-64A units in the United States, West Germany and in Korea, where they play a major role in achieving the US Army's security missions.

By late 1996, McDonnell Douglas Helicopters delivered 937 AH-64A Apaches -- 821 to the U.S. Army and 116 to international customers, including Egypt, Greece, Israel, Saudi Arabia and the United Arab Emirates.

The Apache is clearly one of the most dynamic and important programs in aviation and the Army, but it is not without limitations. Due to the possibility of surging the engines, pilots have been instructed not to fire rockets from in-board stations. According to current doctrine, they are to fire no more than pairs with two outboard launchers every three seconds, or fire with only one outboard launcher installed without restrictions (ripples permitted). These are the only conditions permitted. Other firing conditions will be required to be approved via a System Safety Risk Assessment (SSRA).

The improvement of aircraft systems troubleshooting is a high priority issue for O&S Cost reduction. Because of funding cuts, the level of contractor support to the field has been reduced. This results in higher costs in no fault found removals, maintenance man hours, and aircraft down time. The Apache PM, US Army Aviation Logistics School, and Boeing are currently undertaking several initiatives. Upgrading and improving the soldier's ability to quickly and accurately fault isolate the Apache weapons system is and will continue to be an O&S priority until all issues are resolved.

Prime Vendor Support (PVS) for the entire fleet of AH-64s is a pilot program for the Army, and may become a pilot program for the Department of Defense. PVS will place virtually all of Apache's wholesale logistic responsibility under a single contract. The Apache flying hour program will provide upfront funding for spares, repairables, contractor technical experts, and reliability improvements. Starting at the flight line there will be contractor expert technicians with advanced troubleshooting capability assigned to each Apache Battalion. At the highest level, PVS represents a single contractor focal point for spares and repairs. The intent is to break the current budget and requirements cycle that has Apache at 67% supply availability with several thousand lines at zero balance.

Modernization Through Spares (MTS) is a spares/component improvement strategy applied throughout the acquisition life cycle and is based on technology insertion to enhance systems and extend useful life while reducing costs. The MTS initiative seeks to leverage current procurement funds and modernize individual system spares thereby incrementally improving these systems. MTS is accomplished via the "spares" acquisition process. MTS, a subset of acquisition reform, seeks to improve an end item's spare components. The emphasis is on form, fit and function, allowing a supplier greater design and manufacturing flexibility to exploit technology used in the commercial marketplace.

Apache MTS focuses on the insertion of the latest technology into the design and manufacture of select spares. This is to be accomplished without government research and development (R&D) funds, but rather, uses industry investment. Industry, in turn, recoups this investment through the sale of improved hardware via long term contracts.

Modernization efforts continue to improve the performance envelope of the AH-64A while reducing the cost of ownership. Major modernization efforts within the AH-64A fleet are funded and on schedule. GG Rotor modifications were finished in April 1998,, and future improvements such as a Second Generation FLIR, a High Frequency Non-Line of Sight NOE radio, and an internal fully crashworthy auxiliary fuel tank are all on the verge of becoming a reality for the Apache.

The Aviation Mission Planning System (AMPS) and the Data Transfer Cartridge (DTC) are tools for the Embedded Global Positioning Inertial Navigation Unit (EGI) equipped AH-64A aircraft that allow aircrews to plan missions and download the information to a DTC installed in the Data Transfer Receptacle (DTR). This saves the pilots a lot of "fat fingering" and eliminates the worry of everyone being on the same "sheet of music". Other features of the DTC include; saving waypoints and targets and troubleshooting. The EGI program is a Tri-service program with the Army, Air Force and Navy.

UH-60 Black Hawk

Description: The Black Hawk is the Army痴 front-line utility helicopter used for air assault, air cavalry, and aeromedical evacuation units. It is designed to carry 11 combat-loaded, air assault troops, and it is capable of moving a 105-millimeter howitzer and 30 rounds of ammunition. First deployed in 1978, the Black Hawk痴 advanced technology makes it easy to maintain in the field. The Black Hawk has performed admirably in a variety of missions, including air assault, air cavalry and aeromedical evacuations. In addition, modified Black Hawks operate as command and control, electronic warfare, and special operations platforms.

The Black Hawk is the primary division-level transport helicopter, providing dramatic improvements in troop capacity and cargo lift capability compared to the UH-1 Series "Huey" it replaces. The UH-60A, with a crew of three, can lift an entire 11-man fully-equipped infantry squad in most weather conditions. It can be configured to carry four litters, by removing eight troop seats, in the MedEval role. Both the pilot and co-pilot are provided with armor-protective seats. Protective armor on the Black Hawk can withstand hits from 23mm shells. The Black Hawk has a cargo hook for external lift missions. The Black Hawk has provisions for door mounting of two M60D 7.62mm machine guns on the M144 armament subsystem, and can disperse chaff and infrared jamming flares using the M130 general purpose dispenser. The Black Hawk has a composite titanium and fiberglass four-bladed main rotor, is powered by two General Electric T700-GE-700 1622 shp turboshaft engines, and has a speed of 163 mph (142 knots).

Elements of the U.S. Army Aviation UH-60A/l Blackhawk helicopter fleet will begin reaching their sevice life goal of 25 years in 2002. In order for the fleet to remain operationally effective through the time period 2025-2030 the aircraft will need to go through an inspection, refurbishment, and modernization process that will validate the structural integrity of the airframe, incorporate improvements in sub-systems so as to reduce maintenance requirements, and modernize the mission equipment and avionics to the levels compatible with Force XXI and Army After Next (AAN) demands.

A Service Life Extension Program (SLEP) is planned for the UH-60 beginning in FY99. The UH-60 modernization program will identify material requirements to effectively address known operational deficiencies to ensure the Black Hawk is equipped and capable of meeting battlefield requirements through the 2025-2030 timeframe. Primary modernization areas for consideration are: increased lift, advanced avionics (digital communications and navigation suites), enhanced aircraft survivability equipment (ASE), increased reliability and maintainability (R & M), airframe service life extension (SLEP), and reduced operations and support (O & S) costs. Suspense date for the approved Operational Requirements Document (ORD) is December 1998.

History: The UH-60A, first flown in October 1974, was developed as a result of the Utility Tactical Transport Aircraft System (UTTAS) program. The UTTAS was designed for troop transport, command and control, MedEvac, and reconnaissance, to replace the UH-1 Series "Huey" in the combat assault role. In August 1972, the U.S. Army selected the Sikorsky (model S-70) YUH-60A and the Boeing Vertol (model 237) YUH-61A (1974) as competitors in the Utility Tactical Transport Aircraft System (UTTAS) program. The Boeing Vertol YUH-61A had a four-bladed composite rotor, was powered by the same General Electric T700 engine as the Sikorsky YUH-60A, and could carry 11 troops. In December 1976 Sikorsky won the competition to produce the UH-60A, subsequently named the Black Hawk.

Variants: The Army began fielding the UH-60 in 1978. From 1978 until 1989 the Army procured UH-60A model aircraft. In October 1989, a power train upgrade resulted in a model designation change from UH-60A to UH-60L. The UH-60L version that provides 24 percent more power than the original 1970 UH-60A model. As of the end of FY97, the Army had procured 483 UH-60L models for a total UH-60 acquisition of 1,463 aircraft. The Army is in the fifth and final year of a multi-year procurement contract calling for the delivery of 60 aircraft per year.

UH-60L: In October 1989, the engines were upgraded to two General Electric T700-GE-701C 1890 shp turboshaft engines, and an improved durability gear box was added, resulting in a model designation change from UH-60A to UH-60L. The T700-GE-701C has better high altitude and hot weather performance, greater lifting capacity, and improved corrosion protection.

The UH-60 Firehawk is a Reseach and Development program to provide the UH-60 series helicopter with both a wartime and peacetime fire fighting capability by use of a detachable 1,000 gal. belly tank. Qualification issues include design and testing required to maintain the combat capabilities of the UH-60 Black Hawk and the safe flight envelope of the aircraft with the tank.

The EH-60A Electronic Countermeasures (ECM) variant has a unique external antenna designed to intercept and jam enemy communications. The EH-60E is powered by two General Electric T700-GE-700 1622 shp turboshaft engines.

The EH-60B version has a Stand-Off Target Acquisition System designed to detect the movement of enemy forces on the battlefield and relay the information to a ground station.

UH-60Q Medevac: The UH-60Q MEDEVAC helicopter provides significant enroute patient care enhancements. The UH-60Q provides a 6 patient litter system, on-board oxygen generation, and a medical suction system. UH-60Q is a UH-60A derivative and incorporates approximate UH-60A characteristics. It is simply the best in aeromedical evacuation. Building on the BLACK HAWK's heritage of saving lives in Grenada, Panama, Kuwait and Somalia, the UH-60Q delivers exceptional patient care, increased survivability, longer range, greater speed and added missions capability. For military combatants. War victims. Civilians injured in natural disasters. It has a state-of-the-art medical interior that can accomodate a crew of three and up to six acute care patients. The UH-60Q's leading-edge technology incorporates an improved environmental control system. Cardiac monitoring systems. Oxygen generation, distribution and suction systems. Airway management capability. Provision for stowing IV solutions. And an external electrical rescue hoist. And in addition to extensive immediate care, the UH-60Q can perform all weather terrain battlefield evacuation, combat search and rescue, hospital ship lifeline missions, deep operations support, forward surgical team transport, medical logistics resupply, medical personnel movement, patient regulating, disaster/humanitarian relief, and MAST/HELP state support.

The UH-60Q's medical interior can accomodate three to six acute care patients and their medical attendants. Ergonomic design has maximized the UH-60Q cabin space, placing sophisticated, life-saving instruments and equipment at the fingertips of the medical attendants. A unique platform design allows the interior to transport either six litter of seven ambulatory systems, oxygen distribution and suction systems, airway management capability, and provisions for stowing intravenous solutions. The interior also features these additional capabilities, essentical to providing the highest degree of patient care when every second counts:

- Oxygen Generating Systems
- NVG Compatible Lighting Throughout
- Environmental Control System
- Medical Equipment
- Patient Monitoring Equipment
- Neonatal Isolettes

Modernizing the Medical Evacuation (MEDEVAC) system is the Army Surgeon General's number one near term priority. The UH-60Q communications architecture provides situational awareness and digital communications and is expected to be the model for anticipated fleet-wide improvements to the UH-60. Other improvements include integrated Doppler/GPS, Personnel Locator System, NVG interior lighting, and FLIR.

AH-1W Super Cobra

Function: Fire support and security for forward and rear area forces, point target/anti-armor, anti-helicopter, armed escort, supporting arms control and coordination, point and limited area air defense from enemy fixed-wing aircraft, armed and visual reconnaissance.

History: The Marine Corps deployed four of six active force squadrons (48 AH-1Ws) to Southwest Asia during Operation Desert Shield/Desert Storm. These helicopters destroyed 97 tanks, 104 armored personnel carriers and vehicles, 16 bunkers and two antiaircraft artillery sites without the loss of any aircraft. The deployment required no additional augmentation to squadron support personnel and only one Bell Helicopter technical representative.

Description: The AH-1W Super Cobra is a day/night marginal weather Marine Corps attack helicopter that provides enroute escort for our assault helicopters and their embarked forces. The AH-1W is a two-place, tandem-seat, twin-engine helicopter capable of land- or sea-based operations. The AH-1W provides fire support and fire support coordination to the landing force during amphibious assaults and subsequent operations ashore. The AH-1W is operated in eight composite HMLA squadrons composed of 18 AH-1 and 9 UH-1 aircraft. The AH-1W is curretnly being outfitted with a Night Targeting System/Forward Looking Infrared Radar that provides laser rangefinding/designating and camera capabilities.
