Wave 2 of my fictional Army, ground forces, a fighter, A Mech, and a Core ship, I guess

New fleet arrival, they also totally didn’t copy the Yamato’s design they would never do that,Anyways meet the Dimensional sub, Dreadnought and Battleship, the Newest component’s in the fleet.. l o r e: (haven’t figured out abunch of it) so basically these guys were a massive trading company giving resources to others and barely had any warships, until some alien fleets like Gamilons appeared and Stole a whole cargo fleet which was a heavy loss for the Trading company, then they searched Starship graveyards and made a few types of warships, and every convoy sent out, there would be 3 or more Warships guarding it, however sometimes the intimidation tactic doesn’t work and the cargo gets stolen anyways, that’s it for lore
