Designation:
Thuverl Garmanna Mar-class Battleship
Note: While Marduk ships have been assigned Terran naval/space type
designators, it must be stressed that their size and armaments placed them in a
class of their own, matched only by contemporary construction of like
designations. As such, their designations must be viewed as indicators of intent
and use rather than absolute strength.
Names and disposition:
These ships were built at numerous locations throughout the Marduk Empire for
several thousand years. There has only been one version of the design; though
subsystems such as the fold system were upgraded over time, the impacts were not
major enough to warrant a new version number.
The exact number of constructed units cannot be given due to the loss of
records. However, an estimated guess puts their number at approx. 1.2 million
units.
Of this number, approx. 210,000 were destroyed prior to 2063. Approx. 820,000
of the remaining units were destroyed during the 4th Robotech War
(2063-2070). Estimates place the total units remaining at approx. 170,000
dispersed throughout the galaxy.
Ship's complement:
- Ships' crew (1000 men)
- Zentran troops (6000 combat ready, 15,000 in cryo-stasis)
- Meltran troops (2500 combat ready, 6500 in cryo-stasis)
- Marduk troops (2200 combat ready, 500 in cryo-stasis)
- Emulators (4)
- Life support limits are for a full combat complement and about 38400
supernumaries (40,000 men total).
Note: The given numbers are approximations; the exact number varied
somewhat due to operational realities and different ships.
Dimensions:
- Length: 2500 meters overall
- Height: 714 meters overall
- Width: 610 meters overall
- Fuel Mass:
48,000,000 metric tons
- Operational mass (typical):
150,000,000
metric tons
Propulsion systems:
-
Main power system(1): Anti-matter reflex furnace cluster.
The powerplant of a Tolon Kerol Mar-class vessel can nominally deliver up to
150 Petawatts of power, and can operate for 120 minutes at maximum power
before overheat initiates auto-shutdown.
- Maneuvering thrusters (65) : Fusion-plasma reaction
thruster clusters with steerable nozzles. There are 4 on the forward and
aft dorsal hull, 16 on the central dorsal hull, 3 on the forward and aft sides
and 10 in the central sides, 8 thrusters low in the nose, 8 mounted on the
forward ventral, 8 in the central ventral and 8 in the aft ventral.
- Reaction-mass thrusters (4) : All are fusion-plasma
reaction thrusters with anti-matter energizer. Mounted in two pairs of
two on either side of the stern. There are no forward thrusters;
breaking maneuvers are made with the aft main thrusters using exhaust
deflectors opening in the engine pods and through ports in the upper aft hull.
- Anti-gravity system (1): 340 anti-gravity pods.
- Space fold (1): Spacefold Drive. This system generates a
hull-conformal fold.
- Planetary capabilities: The Battleship-class has
atmospheric capabilities through its reaction engines and anti-gravity
systems. The hull has sufficient structural strength to make a cold landing,
but the landing field requires extensive preparations to increase its
carrying capacity and equalize the terrain. The ship will float in an ocean,
but only the upper ingress/egress ports will open above the waterline, which
greatly hampers access to the ship.
Endurance and mobility limits:
(all estimated based on storage space, fuel capacity
and similarities to Local Group designed ships)
- The dry stores endurance is 20 months maximum; after that, the ships of
this class need to restock. Water stores are recycled almost totally. If
fewer or no auxiliary vessels are carried, the freed hangar space can be
used to store additional consumables.
- The mecha consumables supplies (mainly missiles) are able to sustain
continuous combat operations for more than 20 days.
The missile magazines
for the ship's own launchers are typically empty after three major space
battles.
- At full power, the main propulsion systems can nominally produce up to 2
Teranewtons of thrust at a minimal reaction mass efficiency profile, or as
little as 39 Giganewtons of thrust at a maximum efficiency setting. At lower
power levels, these thrusts are commensurately smaller.
- At full power, the Battleship can nominally achieve a maximum delta-v
of 320 kps at the cruising acceleration of 0.3G, a maximum delta-v of 88 kps
at the battle acceleration of 1.4G, and a delta-v of at most 37.3 kps at the
flank acceleration of 2.7G. At lower power levels, these
ranges are commensurately smaller.
- The fold systems were not navigationally guaranteed for any single jump
beyond 10 kiloparsecs. If longer voyages were required, the ship had to
conduct multiple fold jumps.
- The maximum sustained atmospheric speed is Mach 4. The maximum hover time
on the anti-gravity systems is limited only by maintenance requirements.
- The hull has a designed life-time (including regular refits) of
approximately 12000 years.
Weapon systems
- Mini-reflex cannon(1): Much like its Terran counterpart,
the Marduk Reflex Cannon is a scaled version of the same cannon found on
their dreadnaught and flagship. This cannon can fire 75,000 km with a discharge of over 25
MT of TNT. This weapon has slightly inferior rate of fire though of only
once every minute.
-
Tachyon cannon(4): The main anti-ship weapons are four tachyon
cannon mounted in the nose. The tachyon beam has an
effective range of 50,000 km. and a full power discharge of 200.1 GJ. Although
the cannon could be fired at lower power settings (and commensurate increases
in the rate of fire) the highest power setting was typical in combat. The rate
of fire at this setting was approximately five salvos per minute.
- Reaper cannon (70) : This the Marduk variation on the
Zentraedi combination cannon. Two different beam weapons (variable
frequency laser and reaper cannon) are provided on one mount so that the
discharge medium can be chosen as the optimum for the local target and
environment conditions. Both weapons have the same yield at the muzzle. The
laser can be fired in a low power mode directly before the particle beam
fires, this setting is typically used to burn a vacuum path for the particles
through an atmosphere. Because of the slow recharge time of the larger
weapons, and the flexibility inherent in the double mount, this cannon turret
is the weapon system most often utilized on board Marduk vessels. For ground
support, it is the only effective weapon as the other systems are to heavy to
be used around own troops. The cannon has an effective range of 70,000 km.
Each full-intensity shot has a yield of 2.3 GJ, and the cannons can cycle
through their firing sequence once every three seconds. The
exact location of these weapons varied by building yard, but the most common
scheme mounted thirty turrets forward, aft, to each side and to the dorsal
and ventral, though most mounts had a field of fire that extended to other
planes.
- Torpedo tubes(30): A reloadable Silo Launch System (RSLS),
or as it is better known, a torpedo tube, capable of firing large anti-ship
and ground bombardment torpedoes. The tubes can reload in 10 seconds, and
have a 20 round magazine close-by. The missiles used are the ASZM-1 Asteroth,
ASZM-2
Basilisk,
ASZM-3 Serephis. The former is a nuclear missile with a 450
kT reaction warhead, the second is a conventional tipped missile with a
warhead of 1 metric ton. The third is an interesting weapon which is only used
to disrupt enemy communications and radar. It sends off a massive EM pulse and
acts after that as a jammer station. All missiles are
optimized for anti-ship strikes in deep space, but can be used in orbital
bombardment modes or in an atmosphere.
- Missile launchers(120): A missile launcher mounted in a
pop-up turret, firing anti-mecha/missile missiles, though the projectiles
can guide on point-blank enemy ships. The turret run by an AI system which
selects the best missile for the target. The most common missile
system used is the
SAZM-1 Lucifer, a weapon with a conventional blast
fragmentation warhead of 60 kg and an atmospheric range of 40 km. at a
speed of Mach 12.5. If heavier targets are present, then often it will be
the SAZM-2 Cain, a weapon with a
180 kg blast fragmentation warhead and a
range of 15 km. If faster targets are present then the missile of
choice is the SAZM-3
Lilith which has a 30 kg fragmentation warhead, but has a top speed of
Mach 15 and a range of 20 km. When the missiles are released they
are already on their intercept vectors, or very close to them. Each turret
has a reload time of 6 seconds and a magazine with a 800 round capacity.
They are mounted for spherical coverage.
Air group and mecha complement:
Note: The given numbers are approximations; the exact number and
type of mecha varied somewhat due to operational realities and different ships.
Design notes:
History:
Unknown. Sketchy details exist but nothing concrete. Most information has
been classified top secret by the RDF and UNT Government.
