The An-71 Madcap was a modified An-72 with an AEW radome on the forward swept tailfin intended for service on the "Tbilisi" (AKA "Admiral Kuznetsov") aircraft carrier. The aircraft also featured substantially extended wingspan -- about six meters greater than the An-72 -- and other minor refinements. Three aircraft were built before the An-71 was cancelled in favor of the twin-turboprop Yak-44 [which was in turn cancelled in 1993].
