New information from a Hobby Japan magazine (translated by Tim Eldred I believe)
Also some mechanical info.
Cosmo Tiger I (Trial production tactical assault fighter)
One of the prototype aircraft which competes as the next-generation primary fighter for the Earth Defense Forces. Since it is a larger craft equipped with a large quantity of weapons and a high-output engine, it was difficult to operate as a carrier-based fighter and was rejected. Akira Yamamoto flies it and trains rookies as an instructor on the moon base.
Cosmo Tiger II (Comprehensive space assault fighter)
The successor to the Cosmo Falcon, whose excellence was proved as Yamato's fightercraft. Equipped with 18 machine guns and normal equipment for high mobility, its performance has dramatically improved. The members of Yamato's flight core train rookies to fly the plane at the moon base.
Murasame-type Space Cruiser Saratoga
Following the basic design of the old Murasame space cruiser, the Earth Defense Fleet equipped this model with a new engine that includes a Wave Core. It is deployed by the space forces of countries around the world, as exemplified by English names such as Saratoga and Defiant.
Kongo-type Space Battleship Yuunagi
As the main battleship of the reorganized Earth Defense Fleet, it follows the basic design of the Kongo-type space battleship, it is equipped with a new engine containing a Wave Core. It is capable of warp travel, is equipped with a new type of space torpedo, and its main battery consists of four 36cm tri-positron shock cannons that reinforce its output. Susumu Kodai is the captain of Yuunagi, unit 47 of the 2nd escort fleet.
Gaizengan weapons group - Calakmul-class battleship*
A heavy battleship of Gatlantis that measures 520m in length. The design concept of its hull is very different from other ships, which characterizes it with unique operating requirements. In addition to the standard rotary turrets, it has a special firing system called a Lightning Strike Gun.
Crustacean Assault Craft Deathvatator**
The main assault fighter of Gatlantis. It is equipped with a rotary beam machine gun (quick-fire rotating turret) on its upper surface. 8 machine guns are fixed on the front of the hull. It is piloted by a crew of three, and carries six air-to-air missiles on its underside, or it can mount a single large anti-ship missile.
Medalusa-class Heavy Annihilation Battleship
This heavy Gatlantis battleship wields a Flame Strike Gun that warps a powerful blast of energy to allow for long-distance bombardment from outside an opponent's range. Yamato met with a similar warship on its return from Iscandar, which has since been mass-produced and deployed with the Gatlantis fleet in large numbers.
* "Calakmul" follows the tradition of giving ancient South American names to Gatlantis mecha.

** There has been long-standing confusion over the name "Desbatata" for the hermit-crab-shaped fighter. The assumption has always been that it was a misspelled version of "Devastator." After consulting with 2202 supervising director
Nobuyoshi Habara, I learned another explanation: it probably started out as "Devastator" and was modified into "Death-vatator." ("Des" being a phonetic Japanese version of "Death.") Until further evidence is found, I'll be going with "Deathvatator" in all future texts
