Anything required to make realistic 1960ish missions:
B-52B, B-47, B-58, KC-135A
all British Planes of the era, Lightning, V-Bombers, Scimitar, Vixen, Transports like Blackburn Beverley etc., a carrier too like HMS ArkRoyal R09 or a Clossus-class (though I guess that'll come with the Falklands map)
