In previous planes, the back-facing gunners had been in the fuselage, but their view there was obstructed. A similar arrangement (using nacelle-mounted gun platforms) was adopted in the competing Keystone XB-1 aircraft. The XB-2 competed for a

Furthermore, the B-2 was large for the time and difficult to fit into existing

a production run of 12 was ordered. One modified B-2, dubbed the B-2A, featured dual controls for both the pilot and the copilot. Previously, the control wheel and the pitch controls could only be handled by one person at a time. This "dual control" setup became standard on all bombers by the 1930s. There was no production line for the B-2A. The B-2 design was also used as a transport. The B-2 was quickly made obsolete by technological advances of the 1930s, and served only briefly with the Army Air Corps, being removed from service by
