Imperial Army Sea Force

The Imperial Toishiman Army Sea Force (帝国軍海部隊, TGUB), is the terrestrial aquatic naval force under the Imperial Army. It is responsible for contesting and securing the waters of planets where large campaigns are being carried out, and also acts in a global logistics role. On Imperial planets, the Sea Force also acts in a defensive manner as part of the ground-based defences of the planet.

Descended directly from the ancient naval forces of Izumo, the Sea Force has existed since 259 MGS.

Equipment
The Sea Force uses several types of naval ships, all of which are heavily automated and have a small crew compared to their size.

1 class of Patrol Ship- Hatsuyuki ripoff.

1 class of all-purpose destroyer- Littoral Combat Ship. But bigger. Also can handle minesweeping and everything else.

1 class of all-purpose Missile Destroyer- Atago ripoff, maybe. Also can handle minesweeping and everything else. Uses a powerful underwater sonic pulse weapon to destroy mines. (COD Ghosts sonar pulse) Can fire ground-to-space missiles and intercontinentals.

2 classes of submarine- Hunter-Killers and ballistics. Ballistics can fire ground-to-spacers and intercontinentals.

2 classes of Aircraft Carrier- Small and big. Small ones are Izumo ripoffs. Big ones are Admiral 56s.
