Battle Class Heavy Destroyer
(Version 1.00 - Last Modified: 02/17/2006)
- Background information inspired by
Battle Class Super
Dimensional Heavy Cruiser (SCA) by Pieter Thomassen, with Peter Walker and Rob
Morgenstern on the
Unofficial Robotech
Reference Guide.
After the Zentraedi Malcontent Uprisings had been put down, attention was directed into a defensive
fleet and into the Pioneer Mission, which was to either make peace with the Zentraedis' masters, the
Robotech Masters, or, if this proved to be impossible, to keep the next war away from the Solar
System. The Battle class was designed as a compromise: they had to be capable of serving as
interstellar war vessels in the Expeditionary Force, but also had to be capable point-defenders in
their role as Earth's guardians. This was accomplished with the extensive missile batteries and the
RMS-3 missiles with the REF and with the Spacelord missiles of the Southern Cross. The RDF Space
Forces, on recon missions into Tirolian territory, heavily used the first Battle class vessels.
Unfortunately, the enemies against whom the Human forces would have to fight were the Invid and the
Robotech Masters, not the Zentraedi. The more advanced technology of the Masters made the large
warheads on the Spacelord rockets mostly useless. They sometimes managed to blast holes in the hulls
of the Azashar vessels, through which ground troops were then inserted, but this was not an effective
tactic. Most military minds agree that while the Southern Cross fought valiantly, it also fought
rather amateurishly.
The Invid did not have the technology the Masters had, but unlike the Masters and their Zentraedi,
the Invid relied more on overwhelming numbers of mecha in any particular engagement, rather than on
large and powerful starships. This left the RMS-3 missiles carried by the REF ships with far fewer
viable targets than their Southern Cross counterparts were presented with. This caused the REF to
reequip its remaining destroyers as depot ships and flotilla leaders for the Garfish class destroyers
after its own Karbarran based building program came into full swing, as the Garfish destroyers, with
its heavy turret, was far more capable against multiple Invid Mollusk Carriers than the Battle class.
Proposals to refit the existing Battle class vessels and reopen the production lines for these
vessels were not accepted, though more because of the far faster building rate of the Garfish
destroyers than because of an unsuited nature of the Battle to modification. In fact, the Battle
class is, on pure vessel qualities, considered superior to the Garfish class, though also far heavier
and expensive. Not long after 2038, almost all surviving REF vessels were in reserve storage.
The Battle class was represented in the REF with thirty vessels, ten of which were sent back to Earth
with the Marcus Antonius, only to be destroyed in the Second Robotech War and the Invid Invasion. Ten
others were destroyed over various planets during the Sentinels' War, and four ships were destroyed
during the REF Civil War. Of the remaining six vessels, all were decommissioned and placed in storage
in the Valivarre System.
The Battle destroyers were the backbone of the SC Aerospace Forces, and was an important class for
the REF as well. Its design is very much like that of the Banshee, only larger in all respects. For
instance, the side sponsons house two engines each, as well as the two double fighter bays and a
launch pad. The hull has one launch / recovery chute for mecha, halfway down the hull, serving another
double hangar. These bays can hold 4 squadrons for 48 mecha total with room for a few other craft in
the REF vessels, or, due to the smaller size of their fighters, 6 squadrons for a total of 72 mecha in
the SC configurations. The bridge is located in a spade-shaped deck atop a low tower on the upper main
hull. The vessel can hold several Special Forces squads, and the RDF ships often held such forces
during the recon operations in the late 2010's.
The cannon armament was small but sufficient for the intended tasks: to provide additional anti-ship
firing power to aid the larger capital ships and to perform small actions as the flagship of a detached
light force. The RG-60 rail cannon was devastating in its effect and damage concentration; however, the
mount held a limited amount of fire and the nimble Invid usually managed to dodge most salvos. The
Southern Cross later ordered an upgraded version with a different armament suite; in these vessels
(SDD-80 onwards) the rail gun was replaced with a particle weapon, as previously mounted in the Ajax and
Tristar classes. This change caused an increase in long range firepower.

- Gravity System: Internal
Weapon Systems:
- RG-60 Electromagnetic Rail Gun Turret (SDB-variant only)
This heavy weapon is designed for close range combat and is quite powerful. This weapon was useful
against Invid clam ships, but because of its relative low range, the Invid were usually able to
deploy before it had a chance to fire. The turret is stored in the foot of the command tower.
- Range: 3.2 miles (5.1 km) underwater, 32 miles (51.4 km) through an atmosphere, and
32,000 miles (51,499 km) in space.

- M.D.C. Weapon Rating: 25
- Rate of Fire: Each cannon can fire six times per melee.
- Payload: 240 rounds
- PB-25 Particle Beam Cannon Turret
This twin-cannon turret is not as powerful as the PB-45 turret, but was designed for combat against
smaller vessels. This weapon is mounted between the RG-60 turret and the command tower.
- Range: 62.1 miles (100 km) underwater, 124.3 miles (200 km) through an atmosphere, and
124,274 miles (200,000 km) in space.

- M.D.C. Weapon Rating: 24
- Rate of Fire: Each cannon can fire four times per melee round.
- Payload: Effectively unlimited
- PB-4 Particle Beam Cannons (11)
These retractable cannons are an improved version of the PB-2 Particle Cannons used on the old Oberth
destroyers. These cannons are not quite capable enough to be effective against ships larger than the
Zentraedi Tou Redir scouts, the Tirolian Roil Tiluvo assault corvettes, or the Invid Mollusk carriers.
There are four on the dorsal side sponsons, two on the ventral side sponsons, two on the sides of the
superstructure, two on the sides of the forward hull, and one on the dorsal forward hull.

- M.D.C. Weapon Rating: 24
- Rate of Fire: Each cannon can fire six times per melee round.
- Payload: Effectively unlimited
- LT-5 Point Defense Laser Turrets (8)
The LT-5 lasers are designed to deliver heavy firepower on very close targets. A double-barreled laser
with a round sensor between the barrels, the LT-5 is stored inside the hull, but elevates upwards from
under movable panels into firing position. Four turrets are mounted around the engines and the other
four are in the forward hull.
- Range: 1.6 miles (2.5 km) underwater, 3.1 miles (5 km) through an atmosphere, and
310.7 miles (500 km) in space.
- Damage: 2D6x10 M.D. per single blast.
- M.D.C. Weapon Rating: 23
- Rate of Fire: Each turret can fire four times per melee round.
- Payload: Effectively unlimited
- SLS-25 Vertical Missile Launchers (4)
This system replaces the Pepperbox launchers used on old RDF ship designs. This new system consists
of two rows of five launch tubes for each missile launcher, this allows for an even higher rate of
fire. These launchers are located in the dorsal and ventral side sponsons.
- Missile Design: Hughes Warhawk and General Dynamics / Euromissile / BAe Spacehawk Long
Range Missiles
- Missile Type: Anti-Spaceship only.
- Missile Guidance Systems: Select any one available guidance system.
- Missile Warhead: Armor Piercing, Fragmentation, High Explosive, Plasma / Napalm, Fuel
Air Explosive, Kinetic Energy, Multi-Warhead, Nuclear, Proton Torpedo, and Reflex only.
- Range: 800 miles (1288 km) in an atmosphere and 935,525 miles (1,505,582 km / 5.0 light
seconds) in space.
- Speed: 2500 mph (4023 km/h) in an atmosphere and an acceleration of 4% of light (0.04c)
per melee in space, with a maximum duration in space of 16 melees and a maximum
safe speed in space of 55% of light (0.55c).
- Damage and Blast Radius: Varies with type of missile warhead.
- Rate of Fire: One at a time or in volleys of any size up to 10 missiles. Each launcher
can fire three times per melee round.
- Payload: 200 missiles per launcher, for a total of 800 long range missiles.
- Modifiers: Increase range in space by 25%, but reduce warhead strength by 10%.
Automatically hits a stationary target in space, has more advanced targeting equipment that
gives a bonus of +6 to strike a moving target, but has a penalty of -10 to strike any target
under 500 tons (453.6 metric tons).
Special Systems:
- Electronic Warfare System
The ship is equipped with a standard REF EW suite.
- ECM: 5
- ECCM: 3
- EWS Abilities: Attract Tracking Device, Break Tracking Device Lock-On, and Scramble
Communications.
Standard Systems:
- Life Support System
The ship has a fully operational life support system that provides fresh atmosphere throughout the
ship. The life support system can sustain a maximum of 600 people indefinitely or 1000 people for
a short period of time in case of an emergency.
- Communication Systems
The ship is equipped with three communication systems. The first is a long range laser system with
a maximum range of 100,000 miles (160,934 km), the transmissions travel at the speed of light, but
they rely on line of sight, so it cannot communicate with a ship that is on the other side of a
solid object. The second system is a long range radio system with a maximum range of 10,000 miles
(16,100 km), the transmissions travel at the speed of light, but they are easy to intercept and jam.
The third system is a satellite relay system that allows the ship to boost the range of the other
communication systems indefinitely by using satellites or other ships to relay the transmission.
The ship's communication array can maintain contact with up to 750 ships simultaneously.
- Sensor Systems
The ship is equipped with three sensor systems. The first is the Electromagnetic Detection Equipment
that detects other sensor systems at twice the maximum range of their transmitter. The second is a
powerful array that uses standard radar waves, which are fairly easy to jam, but it is obvious when
the radar array is being jammed. The sensor can track tiny targets at a range of up to 450,000 miles
(724,205 km), small targets at a range of up to 4.5 million miles (7.2 million km), medium targets at
a range of up to 9 million miles (14.5 million km), and large targets at a range of up to 13.5
million miles (21.7 million km). The third is a Subspace Mass Sensor that uses gravity-based
technology to detect target's at real time speed. The sensor can track tiny targets at a range of up
to 500,000 miles (804,672 km), small targets at a range of up to 5 million miles (8 million km),
medium targets at a range of up to 10 million miles (16.1 million km), and large targets at a range
of up to 15 million miles (24.1 million km). See Human
Ship Systems for more details on sensor systems.
- Targeting Computer System
Connecting the ship's sensor systems with the weapon systems is the Targeting Computer System. The
system is designed to control all of the weapons currently equipped on the ship. This system can
track up to 150 targets simultaneously, providing detailed information about the targets from the
ships data files. All direct fire weapons receive a bonus of +3 to strike and missiles using
non-autonomous guidance systems receive a bonus of +3 to strike. These bonuses are in addition to
any previously stated bonuses or penalties.
