- 10 Destroyed Transient War 2057
- 8,423 Destroyed 4th Robotech War 2063-2068

Ship's complement:
- Ships' crew (200 men)
- Space Naval air group (200 men)
- Space Marine unit (3,200 men)
- Army division (36,000 men)
- Life support limits are for a full combat complement and about 192,000
supernumeraries (200,000 men total).
Note: The given numbers are approximations; the exact number varied
somewhat due to operational realities and different ships.
Dimensions:
- Length:
2000
meters overall
- Height: 600 meters overall
- Width: 200 meters overall
- Fuel Mass: 2,233,000 metric tons
- Operational mass (typical):
36,200,000 metric tons
Propulsion Systems:
- Main power system(1): RRD Mk9 anti-matter Reflex furnace.
The powerplant of the Broadsword-class vessel can deliver up to 180
Petawatts of power, and can operate for two hours at maximum power before
overheat initiates autoshutdown.
- Maneuvering thrusters (22): Overtechnology MRT-6
Fusion-Plasma Reaction Thrusters with steerable nozzles on the bow(6), stern
(6), sides (4 per), ventral hull (2), and dorsal hull (2).
- Reaction-mass thrusters (8): Shizuma MRE-14 Fusion-Plasma
Reaction Thrusters with anti-matter energizer in the rear of the engineering
section of the ship in a straight horizontal bank.
- Anti-gravity system (1): 10 Shizuma Drive Behemoth
anti-gravity pods.
- Sublight drive (10): Shizuma Drive GDD-8
local monopolar-induced gravitic space-time distortion drive.
- Space fold (1): RRD Mk18 spacefold. This system is
conformal to the vessels surface. The problem with the vast majority of the
previous generation of fold systems was that the fold bubble weakened the
state of the structure to the extent that they needed a refit after only
five years of service. As such the RDF mandated the use of conformal systems
similar to the old Zentraedi systems which also allows for much higher
speeds.
- Planetary capabilities: The Broadsword-class has
atmospheric capabilities through its reaction thrusters and anti-gravity
system. The ships' lower body has several retractable landing struts that
have sufficient strength to let the ship land on them, although the landing
ground should be as firm as possible (granite is recommended). The ship
would float in an ocean.
Endurance and mobility limits:
- The dry stores endurance is three months maximum; after that, the Broadsword
needs to restock. Water stores are recycled almost totally.
- The mecha consumables supplies (mainly missiles) are limited; the
Broadsword is unable to sustain continuous combat operations for much more
than a ten days.
- At full power, the main propulsion systems can produce up to 1.6
Teranewtons of thrust at a minimal reaction mass efficiency profile, or as
little as 31 Giganewtons of thrust at a maximum efficiency setting. At lower
power levels, these thrusts are commensurately smaller.
- At full power, the Broadsword-class can achieve a maximum delta-v of 234
kps at the cruising acceleration of 0.1 G, a maximum delta-v of 46.8 kps
at the battle acceleration of 1.0 G, and a delta-v of at most 12.8 kps at
the flank acceleration of 2.3G. At lower power levels, these ranges are
commensurately smaller.
- Sublight drive acceleration is 1100 g, but the vessel's maneuverability is
reduced to such a degree that only minor course corrections are possible.
Typical cruising speed is .20c.
- The Mk18 fold systems are not designed to be used for folds of distances
greater than approximately 5 kiloparsecs, for safety reasons. If longer
voyages are required, the ships must conduct multiple fold jumps.
- The maximum atmospheric speed is Mach 1. The maximum hover time on the
anti-gravity systems is limited only by maintenance requirements.
Weapon systems:
- Europa RIC-12 reaper ion cannon turret(4): The reaper
cannon delivers 4.5 GJ of energy with a range of around 75,000 km, but at a
faster rate of fire of around once every three seconds. The cannon fires
charged atomic particles that impact a target and release radiation and large
amounts of heat melting the armor. This cannon is also very effective against
shields because the radiation interferes with the harmonics of the shield by
delivering EM pulses with the radiation. The four turrets are
mounted in a line down the center top hull of the ship.
- Bofors PL-7 point defense turrets (18): Mounted on the
main hull behind movable panels on the forward section (3), middle section
(4), and engineering (3). TThese standard RDF weapons can fire 53 MJ of
particle energy four times per second at a range of up to 20 km.
Air group and mecha complement:
(Circa 2055)
(Space Naval Air Wing)
(Space Marine Unit)
(Army Division)
- See RDF Army File for details on make up of a division.
(Circa 2063)
(Space Naval Air Wing)
(Space Marine Expeditionary Unit)
(Army Division)
- See RDF Army File for details on make up of a division.
Note: The given numbers are approximations; the exact number and
type of mecha varied somewhat due to operational realities and different ships.
Electronics Systems:
- Hughes DSP-6 pinpoint barrier defense system(1): Uses
four movable disks of force field, conformal to the ship's surface, to repel
light torpedo attacks, or particle beam fire.
