The Consolidated XB-41 Liberator was a single Consolidated B-24D Liberator bomber, serial 41-11822, which was modified for the long-range escort role for U.S. Eighth Air Force bombing missions over Europe during World War II.
Design and development
When the USAAF started strategic bombing in Europe there were no fighters available to escort the bombers all the way to distant targets. The bombers carried several defensive guns and formed up in boxes so that they could provide mutually covering fire but there was interest in providing more firepower for the formation.
The XB-41 Liberator was outfitted with 14 .50 caliber (12.7 mm) machine guns. This was achieved by adding a second dorsal turret and a remotely operated Bendix turret (of the same type as fitted to the YB-40) under the chin to the standard twin gun tail turret and twin gun retractable ventral ball turret, plus twin mount guns at each waist window.Davis 1987, p.24. The port waist mount was originally covered by a Plexiglas bubble; testing showed this caused severe optical distortion and it was removed.
The XB-41 carried 12,420 rounds of ammunition, 4,000 rounds of which were stored in the bomb bay as a reserve. It was powered by four {{convert|1250|hp|kW|abbr=on}} Pratt & Whitney R-1830-43 radial engines.
Operational history
On 29 January 1943, the sole XB-41 was delivered to Eglin Field, Florida. Tests were carried out for two months at Eglin during February 1943.[http://www.historyofwar.org/articles/weapons_XB-41_Liberator.html Consolidated XB-41 Liberator]. Historyofwar.org. Retrieved on 2011-10-31. These indicated significant problems with the aircraft; on 21 March 1943, the Army declared the XB-41 as unsuitable for operational use; the conversion of thirteen Liberators to YB-41 service test aircraft was cancelled. Despite this, Consolidated continued to work on the XB-41 prototype; wide-blade propellers were fitted, and some of the armor was removed to reduce the aircraft's weight. Tests resumed at Eglin on 28 July 1943; however, the basic flaws of the "gunship" concept remained, and the XB-41 program was abandoned. The prototype XB-41 was redesignated TB-24D; it served as an instructional airframe for training mechanics on the B-24. It was scrapped at Maxwell Field, Alabama on 2 February 1945.
