Getting back to the original topic of this thread, I would expect only 2 more jets in AH, if not just 1.
Firstly the Gloster Meteor who was already operating in the theatre of war in 1945, or even late 1944. Although not encountering German planes to fight with, they did shoot down V-1 flying bombs. BTW, a V-1 would be nice to have in AH:D
Secondly, the Henkel-162, who was operable and did enter combat.
Don't think there's more to add, since we have the Arado, 262 and 163.
