Kevin - yes they were used pre-Korea... in fact in researching a squadron that flew in the Battle of Britain, I found out they honed their night fighter tactics in WWI flying Sopwith Camels over enemy airfields at night waiting for one to take off... If I find the web page I will post it to you...
WWII was prolific with night fighters, hurricanes, spitfires, boulton-paul defiants, Bf110's, Ju88's, P-61's etc... etc.. etc.. if you want to know more or more modern aircraft let us know! We can list 100's I am sure, especially during and after WWII.
What era are YOU interested in modeling? that may help us list a few...
