RL WW2 - P-47's are very prominent to me, mostly because one of Republic's manufacturing sites of the P-47 is close by, as well as the B-17, B-25 and C-47.
RL Korea - Vietnam : F-86, Mig-21, F4 Phantom, most importantly the B52.
RL 1980's - Present: F-14 Tomcat, YF-23 (it never got into production but it is easily one of the sexiest looking fighters ever built), Su-35, Mig 1.44, and foremost the Dassualt Rafale and the Saab J-35 Draken.
