Propulsion systems:

  • Main power system: RRG Mk7 protoculture-fueled reflex furnace. The powerplant of these vessels can deliver up to 213 Terawatts of power, and can operate for sixty-eight minutes at maximum power before overheat initiates an autoshutdown.
  • Maneuvering thrusters (8): Fusion-plasma reaction thrusters clusters with steerable nozzles. Four are located in the bottom, two on the sides and two on top of the vessel.
  • Reaction-mass thrusters (4): Westinghouse RT-81M (RT-81T in the Defender-class) fusion-plasma reaction thrusters with protoculture energizer mounted in two horizontal banks of two in the rear of the main hull and the side sponsons.
  • Secondary thrusters (2): SNECMA BCET-2 fusion-plasma reaction thrusters with protoculture energizer in a vertical column between the main reaction thusters.
  • Anti-gravity System (1): 10 RRG Atlas anti-gravity pods.
  • Space fold (1): RRG Mk2a (2013-2024) or Mk2e (after 2025) spacefold. This system generates a hull-conformal fold, and thus the Battles and Defenders cannot transport any other vessels with them.
  • Planetary capabilities: These classes have atmospheric capabilities through its reaction thrusters and anti-gravity system. The hull has five extendable landing legs in the lower hull with sufficient structural strength to make a cold landing on them. In case of emergency, a belly landing can be made.
  • Note that the ground underneath should be as firm as possible. The ship will float in an ocean, but the main access ports in the lower hull will be submerged.

Endurance and mobility limits:

The dry stores endurance is eight months maximum; after that, the classes need to restock. Water stores are recycled almost totally, and many EF crews added hydroponic plants to unused spaces, providing the crew with a limited supply of fresh fruits, but this is insufficient to provide for the crew indefinitely.

The mecha consumables supplies (mainly missiles) are standard for ships of this size; the EF Battle is able to sustain continuous combat operations for about twenty days. The Southern Cross can do so for a longer period as their mecha do not rely so much on missiles; however, because the Southern Cross operated near Earth, their cruisers typically only carried supplies for five days fighting.

The missile magazines for the ship’s own launchers are typically empty after one major space battle.

The Reflex furnace can function for about 25 years at normal usage levels before an energizer rebuild is necessary. Battle launching – Rear

At full power, the main propulsion systems can produce up to 5.58 Giganewtons (Defender-class, 5.85 Giganewtons) of thrust at a minimal reaction mass efficiency profile, or as little as 87 Meganewtons of thrust at a maximum efficiency setting.

At lower power levels, these thrusts are commensurately smaller. At full power, the classes can achieve a maximum delta-v of 174 kps at the cruising acceleration of 0.1 gees, a maximum delta-v of 34.8 kps at the battle acceleration of 1.0 gees, and a delta-v of at most 8.7 kps at the flank acceleration of 3.0 gees. At lower power levels, these ranges are commensurately smaller.

The Mk2 fold systems are not designed to be used for folds of distances greater than approximately one hundred parsecs, for safety reasons. If longer voyages are required, the ships must conduct multiple fold jumps. Furthermore, the Mk2a system could not be operated reliably on multiple consequential jumps, effectively limiting the class to one jump every four hours. After 2025, the improved Mk2e spacefold was refitted to all surviving members of the classes.

The maximum sustained atmospheric speed is Mach 3. The maximum hover time on the anti-gravity systems is limited only by the protoculture supplies and maintenance requirements.

Weapons Systems:

(Geneva-class until 2023):

  • ZNPC-01 (Makral Mossil 918) particle/laser cannon (4): These cannons were salvaged from wrecked Zentraedi vessels after the First Robotech War, shipped to the Moon, and mounted on the Geneva-class cruisers as Terran designed weapons of the required size and firepower were not available yet.
  • For centuries this combined particle beam and laser weapon had been the standard medium cannon armament on Zentraedi vessels. Two different beam weapons (variable frequency laser and particle beam 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. The cannon has an effective range of 300,000 km. Each full-intensity shot has a yield of 1000 MJ, and the cannons can cycle through their firing sequence once every three seconds. Two of these cannons were mounted in front of the command tower, two more on the forward flanks of the Geneva-class.
  • RRG AML-10 laser cannons (15): A somewhat bulky but effective anti-mecha and anti-missile laser weapon firing a 10 MJ pulse every second. Fifteen of these weapons were mounted, four on the dorsal side sponsons, two on the ventral side sponsons, two on the sides of the superstructure, four around the engines, two near the forward curvature of the side sponsons and one on the dorsal forward hull. These weapons and their on-mount sensors are protected by a folding hatch when not in use.
  • TSLS-6 Anti-ship missile launchers (6): A sextuple launcher for the heavy Trident F4 anti-ship ballistic missile. Each missile has a delta-v of 7.5 kps and five separate fusion warheads in the 300 kt range. The launchers are located in the upper side sponsons, three to a side.

(Battle-class through SCA-79):

  • Oto-Melara RG-60 double barrelled rail gun (1): A close range, slow firing but hard hitting weapon. The RG-60 can fire a 1.69 kg heavy projectile at speeds of around 60 kps at a rate of 12 rounds per minute. The on-mount magazine cntains 240 rounds, each of which will impact relatively (to the mount) stationary targets with a kinetic energy of 6100 MJ. However, due to the nature of the weapon, its effective range is less than 400 km. Two types of projectile are available: The Kinetic Core Penetrating (KCP) round which will impact and penetrate until its energy is spent and the Kinetic Penetrating Incendiary round, which vaporizes into a directed plasma jet after breaching the outer armor of a target. The RG-60 is stored in the foot of the command tower, and is ridden out over two rails to its firing position in front of this tower.
  • RRG LT15 Double Laser Turret (1): Installed in a low lying turret, this double barrelled weapon has an effective range of 300,000 km, and delivers 1500 MJ of laser energy every two seconds at the highest rate of fire. The LT15 cannon is mounted in front of the RG-60 on the upper deck of the Battle, in front of the command tower.
  • RRG PB-4 particle turret (11): A fast firing medium calibre particle beam cannon in a low lying round turret. The cannon can fire 400 MJ of particle energy per second as short duration beams or as enclosed particle packets (‘disks’) with an effective range of 300,000 km. This cannon is not quite capable enough to be effective against larger ships than Tou Redirs, Re-entry pods, Assault Carriers or 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.
  • SMS-10 Spacelord vertical missile launch system (4): An anti-ship missile battery located in the two sponsons. The system consists of two rows with five launch tubes for Spacelord missiles. The launchers in each sponson are fed by a magazine in that sponson, each magazine containing 30 reload missiles each, for a total loadout of 160 missiles. The typical warheads are 150 kT reaction warheads for anti-ship use or a high explosive directed energy warhead.
  • RRG RG-2 Point defense turret (4): The RG-2 mount is RG-2 Pop-up Rail Gun Turret designed to deliver heavy firepower on very close targets. A double barrelled rail gun with a round sensor between the barrels, the RG-2 is stored inside the hull, but elevates upwards from under movable panels into firing position. The RG-2 fires 0.227 kg KPI rounds at 25 kps, giving the rounds a kinetic impact energy of 141 MJ. Maximum effective range for this system is 20 km against mecha sized targets, maximum rate of fire is 120 rounds per minute. Four of these cannons are mounted in the hull, near the curvature of the side sponsons.
  • Oerlikon PD-2 Point Defense turret (4): The PD-2 is a double barrelled laser cannon, with an on-mount multi-spectral sensor. Designed for point defense against mecha, missiles and small vessels, the PD-2 delivers 50 MJ of laser energy four times per second. They are mounted around the engines (2) and the forward hull (2), behind movable panels.

(Battle-class from SCA-80):

  • RRG PB45 particle beam system (1): This twin cannon, with an effective range of 300,000 km, is designed to suppress other large spacecraft. It can deliver 4500 MJ per salvo, each barrel firing once every three seconds in a high intensity pulse or in a long duration beam. This cannon is mounted forward of the PB25 and bridge tower on the upper hull.
  • RRG PB25 particle beam system (1): A faster firing, but less powerful weapon than the PB-45 with the same effective range of 300,000 km. Each salvo can deliver 2500 MJ, and the mount can recharge every two seconds. The mount is installed between the PB-45 mount and the bridge tower.
  • RRG PB-4 or PB-4b particle turret (11): A fast firing PB-4b Laser Turret medium calibre particle beam cannon in a low lying round turret. The cannon can fire 400 MJ of particle energy per second as short duration beams or as enclosed particle packets (‘disks’) with an effective range of 100,000 km. This cannon is not quite capable enough to be effective against larger ships than Tou Redirs, Re-entry pods, Assault Carriers or Mollusk carriers. The PB-4b is an improved version with a protruding muzzle and greater reliability. 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.
  • SMS-10 Spacelord vertical missile launch system (4): An anti-ship missile battery located in the two sponsons. The system consists of two rows with five launch tubes for Spacelord missiles.

They are mounted around the engines (2) and the forward hull (2), behind movable panels.

(Heritage-class through ARMD-223):

  • HLBL-2 anti-ship missile launchers (2): A heavy SLBM launcher firing Bomarck II rockets. A Bomarck rocket has a delta-v of 8 kps and a fusion warhead of circa 750 kT. The magazine capacity in each sponson can store 25 missiles. The launcher ejects its missiles upward, where they ignite their engines once free of the ship.

Note: The Battle and Heritage-class ships can accomodate 36 additional fighters by using the launch bays as additional hangars, with the mecha tied down for storage rather than in stalls. However, this was universally unpopular with the pilots as recovery of the additional fighters was not possible, unless a loss rate of 33% was exceeded. Adverse effects on morale lead to the effective abolishment of the practice.

The UEDF in the Second Robotech War used Veritech Hovertanks when other, more space-oriented mecha were in short supply. The UEEF occasionally replaced some fighter squadrons with Destroid platoons for insertion onto enemy planets.

The Southern Cross replaced one squadron of mecha with a combined squadron of EC-32 Raven TAWACS and VE-1 Ostrich airborne early warning Veritechs if a vessel was sent on deep space patrol or exploration missions.

Design Notes:

The Geneva-class was the first Earth built capital ship capable of fold travel, and although only seven were built, the derivative (some might say sister) Battle and Heritage-classes were the backbone of the United Earth Defense Force (UEDF) Tactical Space Corps, and were an important classes for the United Earth Expeditionary Forces (UEEF) 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 of the Battle-class 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 UEEF vessels, or, due to the smaller size of their fighters, 6 squadrons for a total of 72 mecha in some UEDF configurations. The Heritage-class had roughly half the hanger space as the Battle-class due to the Bomarck magazines and thus could only accommodate half the number of fighters. 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 these ships often held such forces during the recon operations immediately prior to the departure of the final UEEF deployments.

The Geneva-class hulls and flight systems were finished before any comparable Terran designed energy weapon system could be installed, and thus the class received scavenged Zentraedi energy weapons and left over anti-mecha laser cannons from the Oberth and ARMD classes. This configuration survived until 2023 when the surviving members were upgraded to the new UEDF standard configuration, and the ships became identical to the Battle-class from SCA-80 onwards.

The increased cannon armament of the Battle-class, reason for the classification to Heavy Cruiser in contrast with the Geneva-classes’ Missile Cruiser designation, was small in number but of sufficient firepower 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 could only fire two slugs per ten seconds, precluding large firing patterns. The Southern Cross later ordered yet another upgraded version with a different armament suite; in these vessels (SCA-80 onwards) the upper laser turret and rail gun were replaced with two heavy particle beam weapons, as previously mounted in the Argonaut and Tristar class. This change caused a marked increase in long range firepower. However, older ships were not upgraded to this new standard.

The Heritage-class Armored Reflex Missile Destroyer (ARMD) filled the same role as the old Niven and Forrestal-classes of ARMDs, employing the heavy Bomarck II C ship-launched anti-spaceship missile. The Bomarck II C featured an improved nuclear warhead with a variable yield that could be dialed from 500 kilotons to 15 megatons. (The Bomarck II A, which the C replaced, had a set yield of 750 kilotons.) The Bomarck II Cs and the the Battle-class’s Spacelord missiles were marginally effective against the Robotech Masters in the Second Robotech War, and against the enemies of the UEEF as they stumbled about on their long voyage. To improve this, the Southern Cross developed a derivative version of the Battle-class and Heritage-class, the Defender-class battlecruiser. This design did not have hangar bays for mecha, but instead mounted large, heavy rocket launchers in their place. This gave the Defender-class a tremendous missile salvo, although the vessels now needed an escort from mecha-equipped ships. The firepower was so high, although the missiles were soon expended, that the Southern Cross named these vessels battlecruisers rather than heavy cruisers.

History:

The Battle-class heavy cruiser and Heritage-class missile destroyer were the workhorses of the UEDF Tactical Space Corps’ fleet, and also one of the backbones of the UEEF, until most of the class was destroyed over Terra in the Second Robotech War. Smaller and easier to build than their larger cousins, the Tristar class, the Battle and Heritage-class, could not by themselves take on the larger Zentraedi ships, although a flotilla certainly could. They were intended to support the heavier ships, or to engage the numerous Tou Redir Zentraedi scout vessels, which they were capable of doing with an excellent chance of success. With this in mind, they carried a few larger and some smaller cannons, and an extensive but medium-sized anti-ship missile battery in the side sponsons. The Battle-class originated in the Geneva-class, which was effectively identical save for a mix of Zentraedi energy weapons and an anti-mecha and heavy missile battery based on the obsolete Oberth-class.

Later, the Southern Cross specified a different armament for their vessels, which improved long-distance fire at the cost of some short range firepower. This cannon fit was however not retrofitted into earlier vessels. In addition, a variant was designed which sacrificed the mecha capacity for a large heavy missile salvo. This sub-class, called the Defender-class battlecruisers, entered service only with the Southern Cross and was completely destroyed in the fighting over Earth during the Second Robotech War.

The first Geneva, Battle and Heritage-class cruisers featured heavily in the initial UN Spacy Reconnaissance Expeditionary Force (REF) missions into the Tirolian Mercantile empire, and especially the later vessels entered the fleets of the UEDF. The Geneva-class had an unfortunate start with the two first vessels being destroyed mere months after commissioning during their first interstellar expedition. While the Geneva and Battle design functioned well in the Expeditionary Forces during their searches, severe shortcomings came to light during the Tirolian invasion in Earth Space during the Second Robotech War. The Southern Cross and many of the recalled Expeditionary Force cruisers suffered extremely heavy losses, as can be seen in the fates of the individual ships. This was due mostly to the vastly more advanced technologies used by the Tirolian Robotech Masters. This made the large warheads on the Bomarck and Spacelord rockets mostly useless. Eventually the Earth Forces were reduced to massive salvos in attempts to overload the close-in defenses and breach the enemy hulls, into which ground forces and battloid-mode aerospace forces were then inserted in the hope of disrupting operations enough to give the combined forces the chance to destroy the enemy vessel. Even this desperate tactic did not yield many results.

Later, most of the remaining vessels of the class were guarding Earth, when the Invid attacked. The Invid did not have the technological advantages the Masters had possessed, but unlike the Masters, they relied more on overwhelming numbers of mecha in any particular engagement, rather than on large and powerful starships. The sheer weight of the Invid attack destroyed most Earth cruisers in the first hours of the war. In deep space, the Expeditionary Forces, depleted by repeated reinforcement waves sent back to Earth, scraped up every ship capable of folding, loaded them with troops and mecha, and dispatched them to Earth. After rendezvous with the surviving Home Fleet vessels, these ships landed numerous divisions on Earth, which succeeded in weakening Invid control of most outlying areas, and completely liberated pockets around the landing sites. Unable to dislodge the Invid, the Battle-class vessels remained with the troops for the next decade, waiting for reinforcements from the Expeditionary Forces rebuilding program. This stalemate lasted until 2043, when the Invid grew strong enough to eliminate the pockets and destroy the ships there. In space, the Expeditionary Forces only retained three Battle-class cruisers, but were preparing to increase their ship production and rebuild the combat forces. However, the lighter Garfish-class cruisers, with their large turret, were as or more capable against the Invid than the Battle-class. Proposals to refit the still existing vessels and reopen Battle production were turned down, although one ship was refitted as a prototype development. The Expeditionary Forces eventually chose to use its remaining Battle-class cruisers as flotilla leaders, but not long after 2041, two of the three surviving Expeditionary Force vessels were in reserve, to ease the demands of fleet support.

As stated, one ship was used as a prototype, and continues to serve to this day as a research vessel for the Bureau of Naval Research. This is the Denmark Strait, which was refitted in 2032 with four large, high volume, rail guns on the sponsons and two RL-36 turrets, identical to those on the Garfish class, on the dorsal and ventral hull.

The Geneva and Battle-class was represented in the UEEF with 34 vessels, ten of which were sent back to Earth with the Marcus Antonius, or later with the first REF counterattack against the Invid. They were all destroyed in the Second Robotech War, the Invid Invasion, or on Earth in 2043. Eighteen others were lost during the previous years to various causes. Of the remaining three vessels, two are mothballed, and the third is the above-mentioned Denmark Strait. Similarly, the Heritage-class was represented in the Expeditionary Forces with 14 vessels, all of which were also destroyed by the beginning of the Invid Occupation of Earth.

There were 3 more Geneva-class ships, 67 other Battle-class vessels, 36 other Heritage-class ships and 12 Defender battle cruisers built in Moon Base Luna. In addition to six Expeditionary Force ships of this class, no less than 68 Southern Cross vessels were destroyed by the Tirolian forces. To these losses must be added the 5 ships that were so heavily damaged after this war that they were scrapped immediately afterwards as constructional total losses. Of the remaining ships, 29 were destroyed in the Invid Invasion. Six other ships escaped or were on Luna completing repairs and refits. They joined the 2031 UEEF counterattack, and were destroyed on Earth in 2043.
