 In March 1945, KG 54 was replaced by Kampfgeschwader 51 (KG 51) with newer model Me 262s, remaining until March 1945 when aircraft operation at the airfield became unsustainable.The Jet aircraft at Giebelstadt drew the attention of the USAAF Eighth Air Force, with no less than five heavy bomber attacks on the airfield between September 1944 and March 1945.In addition, as Giebelstadt came in range of Ninth Air Force B-26 Marauder medium bombers and P-47 Thunderbolt fighter bombers in eastern France, attacks on the airfield by these tactical units with 500-pound General-Purpose bombs; unguided rockets and .50 caliber machine gun sweeps were frequent.
