I can't help myself but I ofen compare the spacecraft of the star wars universe with planes of world war 2. The question about who is which side should be clear
So, starting with the empire:
TIE Fighter - Messerschmitt Bf 109E
TIE Advanced - FW 190A
TIE Bomber - Ju87B Stuka
TIE Interceptor - Me 163 'Komet'
(TIE Defender - Me 262)
Firespray - Messerschmitt Bf 110 'Destroyer'
Lambda shuttle - Ju88 Night Fighter
The rebels are a bit tricky:
X-Wing - Supermarine Spitfire
Y-Wing - Fairey Swordfish
A-Wing - P51 Mustang
B-Wing - P38 Lightning (or P47 Thunderbolt)
HWK - Hawker Hurricane
Millenium Falcon - B-17 (but less speed of course)
