The Messerschmitt Me 262 A-1a/U4 was a standard Me 262 modified to carry a Mk 214 50 mm cannon in the nose. The intention was to provide a weapon capable of destroying an American heavy bomber while remaining outside the range of the bomber formation’s defensive armament. Two prototypes were built. The aircraft was assigned to JV 44 and was flown operationally twice against American bomber streams on 16APR45; the cannon jammed on both flights.
