Prior to the decision to use the B-29, serious consideration was given to using the British Avro Lancaster with its cavernous 33-foot (10 m) bomb bay to deliver the weapon. It would have required much less modification, but would have required additional crew training for the USAAF crews. Major General Leslie R. Groves Jr., the director of the Manhattan Project, and General Henry H. Arnold, the Chief of United States Army Air Forces (USAAF), wished to use an American plane, if this was at all possible.[2]
