why a WWI-WWII era ship in a space navy game? the answer to that is a rather simple one. Uchuu Senken Yamato (Or Starblazers the dreadful english dub of it), Robotech, and a few other series from the 1970's and 1980's used WWII style ship designs for their space ships so effectively the space fleets consisted of flying boats with lazer weaponry and missiles. in fact the Yamato and the Musashi were both WWII era battleships (for those of who you for one reason or other did not know that) Admittedly I always thought the concept of the flying warships kind of silly and was more fond of other more creative ship designs from later anime series. also considering this story takes place in the Uchuu Senken Yamato universe it wouldn't be surprisng for most of EDF's ships to look like WWI and WWII era ships.
