"Flying aircraft carrier concept for the Boeing 747
"In the early 1970s, Boeing conducted a study under a contract from the USAF for an airborne aircraft carrier for up to 10 Boeing Model 985-121 "microfighters", with the ability to launch, retrieve, re-arm, and refuel the microfighters. Boeing believed that the scheme would be able to deliver a flexible and fast carrier platform with global reach, particularly where other bases were not available. Modified versions of the 747-200 and Lockheed C-5A were considered as the base aircraft. The concept, which included a complementary 747 AWACS version with two reconnaissance "microfighters", was considered technically feasible in 1973." Information from Wikipedia."
