    Consolidated XB-41 Liberator Bomber Escort Prototype Aircraft


    The Consolidated XB-41 Liberator was another USAAF attempt at producing a viable flying Gun Bus to escort bomber formations - only one was built.

    Prior to the mass availability of long-range fighter escorts for its bomber formations, the USAAF undertook serious trials with various bomber airframes converted as flying gunships. The concept involved a heavily-armed and -armored aircraft accompanying the bomber fleet into enemy airspace, supplying point defense against intercepting fighters, and guiding the formation back home under protection. Such conversion work involved several of the classic American bombers of the war including the Boeing B-17 "Flying Fortress" and the Consolidated B-24 "Liberator". The former was represented by the "YB-40" (detailed elsewhere on this site) and the latter by the "XB-41" detailed below.

    A B-24D production model was set aside for the conversion work by Consolidated and this involved installation of additional guns and armor protection, the bombing equipment being deleted as a result. A second twin-gunned dorsal turret was added aft of the first and a remote-controlled Bendix powered turret was as added to the "chin" position. Each single-gunned beam position now showcased a twin-gunned arrangement. Two more guns were located at the tail and the Sperry ball turret, with its two machine guns, was retained at its ventral position. Due to the Liberator's low ground profile, the Sperry turret was retractable on take-off and landing actions. To feed the multiple machine gun arrangement, some 12,420 rounds of 0.50 caliber ammunition was to be taken aloft - as such, the bomb bay was used as a reserve for thousands of rounds.

    Work on the XB-41 began in 1942 and the sole prototype was handed over for testing in January of 1943. After just two months of evaluation, the aircraft was written off from contention and this cancelled an initial batch of thirteen examples. It was found that the aircraft gained too much weight and added drag from the added armament, ammunition stocks, and armoring. The exposed positions also added considerable drag making the flying Gun Bus much slower than their intended bomber formations - particularly when the formations had dropped their bomb loads. More work on done on the prototype to make it a viable escort platform but this led to little improvement and the attempt ultimately fell to aviation history.
