# B-24 Liberator units of the United States Army Air Forces

During World War II, the United States Army Air Forces took delivery of its first Consolidated Liberator B-24As in June 1941, although the B-24D was the first production model delivered in quantity in July 1942. B-24s were assigned to every combat Air Force; at peak inventory, the USAAF had 6,043 B-24 Liberators operating worldwide in September 1944.
After the war ended, the Liberator was rapidly withdrawn from USAAF service, being replaced by the Boeing B-29 Superfortress. Literally thousands of Liberators were flown to various disposal units where they were cut up for scrap. Some brand-new late-production B-24Ms from Convair/San Diego and Ford/Willow Run were flown directly from the factory to various reclamation sites such as the scrapyard at RFC Kingman, Arizona in 1945, as the war in Europe had ended and B-29s were doing most of the long-range bombing work in the Pacific.
Only a few Liberators were still around when the United States Air Force was formed in 1947, most of them being used for various research purposes. The last USAF Liberator, a Ford EZB-24M-20-FO serial number 44-51228 used by the Aeronautical Icing Research Laboratory for ice research, was struck off the rolls in 1953. For a time, it was on display at Lackland AFB, Texas, with the armament and gunner positions restored. It is currently at the American Museum at Duxford Aerodrome, England painted as 44-50492, a B-24M that was assigned to the 392d Bombardment Group, 578th Bombardment Squadron.
World War II units and formations are documented here, including variants and other historical information. Heavy bomber training organizations primarily under II Bomber Command in the United States and non-combat units are not included.
