Design notes:

The Tokugawa-class carriers were among the first vessels, after the ARMD platforms and the Oberth-class Missile Destroyers, to be designed by Earth engineers. The Tokugawa class was designed as the systems of the SDF-1 were still being deciphered, and construction started on the class at the same time as the first metal for the SDF-2 was cut. The carriers were designed to copy the armament philosophy of the ARMD platforms, as well as provide bulk transport for stores and personnel. Consequently, the original design saw the class with six of the large FLBG-1 cannons, as well as a large mecha complement and powerful SLBM rocket battery. As the FLBG-1 weapons proved to be a disappointment on the ARMD class, however, the armament scheme was up for change, and the Orbital Fleet's disastrous engagement with the Zentraedi caused a major redesign. The large cannons were removed, and in their place faster firing though far less powerful weapons were mounted. As this, and the orbital slaughter, proved to be the death knell for the ARMD operational philosophy, the ship was reassigned as a back-up aviation ship, and only the still heavy missile battery saved the ships from cancellation and scrapping. However, the class was no longer intended for the battleline, but as a baseship, transport and orbital fire support base.

The six ships of the class were commissioned between 2014 and 2017, and served until the final REF departure in 2023 partially as baseships for the recon flotillas send out to search for Tirol's coordinates and partially as guard ships in the solar system. Some years after the REF's fold-jump to what turned out not to be Tirol, four of the class (save the Hannibal and Aalexander) were refitted as troop carriers, with much of their hangar space converted into mecha holding bays. The Naval Air Arm complement in the remaining hangars was dramatically reduced and an entire Planetary Forces reinforced corps could be embarked. At this point, the designations of the four vessels were changed from those of carriers (SCV) to those of landing ships (SLS).

The battlecarriers were nearly the size of the SDF-1. However, this class of vessel, in the landing ship configuration, suffered from a lower standard of habitability, since so much internal space was dedicated to mecha storage space and the supplies necessary for prolonged campaigns.

The vessels were built in three main sections. The foremost section contained most of the hangars, and was built in the shape of a blunt wedge, with a large superstructure on top, and a smaller substructure to the rear of the section. Aft of this front section came a central section, capped with the command tower. Behind this was the very massive engine section, with no less than twelve major reaction thrusters.

The landing ship were intended to use their own fighters and armaments, and those of the two unconverted ships, to smash through enemy defenses, and then unload their large Planetary Forces detachment in a few hours on the surface. However, the ships became vulnerable during their re-entry to a planet's surface, when they were unwieldy and incapable of outmaneuvering any attack. Therefore, the REF later switched to troop deployments from the Ikazuchi-class heavy cruisers, with support from the new Horizont landing craft.

The major flaws in this class of vessel were the relatively weak armament and the lack of a one-hit-one-kill heavy gun, despite the fact that the ships were never intended for major naval battles. In addition, the landing ships suffered from the lack of sufficient hangar space for all their enormous mecha complement to be delivered rapidly into battle.


As the SDF-1 was being restored and the Orbital Fleet was under construction, new technological advancements saw the design of the follow-up vessels, the SDF-2 and the Tokugawa class. The SDF-2 was to be a copy of the SDF-1, and the Tokugawa's were to be fold capable follow-ups to the ARMD carriers. After the appearance of the Zentraedi, though, the class was no longer considered fit for frontline service due to proven inadequacies in its basic design. In short, it was proven that the Zentraedi were capable of picking off ships with much the same armament as the Tokugawa's from beyond the range where these could answer the attack effectively. However, production was too far along to change the design, and the need for hulls was urgent, so six ships of the class were built regardless. The first ship of the class, the Tokugawa, was launched in January 2015, with the additional vessels following approximately every eight months after.

At first, the vessels saw service as carriers, carrying a large complement of VF-1 Valkyries and later VF-4 Lightnings and Alphas in space superiority and interceptor roles, and several squadrons of the deadly AF-1 Vulture as their primary attack aircraft. The vessels saw several actions during their early lives, including the Tokugawa's support of the Lightning squadrons dispatched to disable a small flotilla of Zentraedi ships that had been hiding in the outer system since the destruction of the Zentraedi Homebase. The class was also used as baseships for the flotillas searching beyond the solar system for the coordinates of the capital world of the Tirolian Empire, Tirol.

Some years after the departure of the final ships of the Expeditionary forces, and of the logistical tail, including the Factory Satellite and the Robotech Repair Factory, the decision was made to convert most of the Tokugawa class from less than capable combat vessels to rather more useful troop carriers, the other ships becoming mobile aircraft bases for the ground troops deployed from their half-sisters. Much of the hangar space was converted into mecha storage hangars, and the berthing capacity was greatly expanded to house the large troop contingent. Four of the six vessels were converted.

The UES Hannibal, one of the unconverted hulls, was despatched to Earth upon reception of a distress call. Upon arrival in Earthspace she engaged and was destroyed by the Tirolian fleet, although some of the fighter squadrons and nearly her entire complement (in escape pods) made it safely to Earth.


Upon receiving the recall orders from the Earth Robotech Defense Forces, the Expeditionary Force moved to prepare its ships for the foldjump home. Since the Tirolian Fleet would have to be opposed primarily by ship-to-ship combat vessels, only the remaining carrier variant, and one Tokugawa class vessel, the UES Marcus Antonius, were included in the first two waves. Used as a stand-off missile battery and fighter carrier, the Alexander did not survive the battles with the Robotech Masters. The Macrus Antonius unloaded her troops near Monument City in 2030, and was still on the ground during the final, costly battles of that war. The troops she brought home were very active in mopping up the remaining Tirolian forces on the planet. As the war was over, the Expeditionary Force retained the other three Tokugawa class vessels in deep space, while it tried to decide on a course of action for the future, now that the Tirolian fleet had been destroyed over Earth.

This all changed with the disruption of communications between the Expeditionary Forces and Earth. It was immediately suspected, after a malfunction had been ruled out, that an enemy force had invaded the planet and had had at least a partial success. The identity of the attackers was unknown, although the warnings given by Tirolian clone citizens, and transmitted the the Expeditionary force, about the race known as the Invid, were reconsidered and thought possible and in fact likely. Nevertheless, the Expeditionary Force could do nothing but respond with almost its entire operational strength. To this end, the three Tokugawa class vessels and their escorts were loaded with all the ground forcess the Expeditionary Force had available. This fleet, which formed, save for a small guard contingent and the SDF-3 Pioneer, which was in dock for repairs, all the Earth Forces could still field, then folded to Earth in 2031. Upon arrival, the fleet confirmed the Invid presence, and the near annihilation of the Armies of the Southern Cross and the Expeditionary Force vessels that had been send back during the Second Robotech War as reinforcements. The losses in the Invid Invasion included the Tokugawa class, UES Marcus Antonius, which had remained over Earth.

After delivering their troops to the surface, the three landing ships ascended again, and made rendezvous at Moon Base Luna. After it becamse clear that neither the Invid nor the Expeditionary Force was capable of dislodging or destroying the other belligerent, the two powers settled into an uneasy cold war, occasionaly heating up with skirmishes between patrols and suprise raids. The surviving Tokugawa class vessels were assigned to the Home Fleet, of which they formed for many years the capital core task group. This reversal to their designed space control role was only possible because of the practically non existant Invid naval presence. The ships were worked hard, and this was aggravated by the fact that Luna was no longer capable of thorough refits, let alone new construction. When in 2038 the first small Expeditionary Forces attack took place, the Tokugawa's, with the other longer serving ships of the Home Fleet, were once again relegated to second line roles, and in 2042, after the disastrous 1st Mars Division attack and upon the arrival of more and more modern ships in the system, the class was reduced to reserve in order to free their crews to help man the new vessels. The class remained in reserve throughout the rest of the war, and are still listed in reserve, although, realistically, they would need an extensive and long overdue refit before entering service again. However, the class is now totally obsolete, and is likely to be stricken and scrapped soon.
