The Boeing B-17B was an improved version of the B-17A. The major changes in the B model included a larger rudder, a larger set of flaps and a redesigned nose. The nose-mounted turret was replaced by a Plexiglas nose making the B-17B about seven inches shorter than the A. The Army Air Corps ordered 39 B-17Bs in 1938-1939.

In October 1942 the B-17Bs were redesignated as RB-17B (R for restricted). These aircraft were used for non-combat training, transport, messenger and liaison duties.
