This crazy idea recently popped into my head and wouldn't go away.

Soo I had to post it.
Make ships with characteristics of the various World War 2 aircraft, like a
B-17G spaceship would have four engines, a two gun chin turret, a two gun dorsal turret, a two gun tail turret, a two gun ventral turret and a single gun turret on each side. It would, of course, be a bomber.
A
P-51D fighter ship would have a single, very powerful engine, six guns and a limited missile capacity.
Including the advanced aircraft Germany was able to design but not produce in large numbers, and the advanced Japanese aircraft which were produced in fairly large numbers, but they had no skilled pilots to fly, would be a nice addition. See The History Channel's 'Secret WW2 Aircraft' documentaries for these. Japan had a couple thousand jet and rocket planes built, many in deep bunkers that probably would've withstood a Fat-man or Little-boy sized atomic bomb. Unfortunately for history buffs, most of those Japanese aircraft were destroyed, while a few examples of Germany's still exist.
'Course the engines would have to point towards the rear, most fighters would have a single engine, centrally located in the back.
Major sites that were attacked (like Pearl Harbor, Berlin, London, Verdun) could be really huge capital ships or installations/stations. Important targets like bridges and dams, shipyards etc could be smaller capital ships.
World War 2 Aircraft (Not quite an all inclusive list, I put a link to the P-61 on the discussion page.)
Some of my favorites are the P-38 Lightning, P-61 Black Widow, and the Douglas B-26 or A-26 Invader; a twin engine light bomber that in some configurations had up to 14 forward firing guns, plus two in a dorsal turret.
I bet y'all think I'm crazy.

Fighter combat and bombing missions in WW2 are the inspiration for games like Freespace! Think there'd be games like this otherwise?
