Design and development
The Keystone B-5 was originally designated LB-14, but the LB- "light bomber" designation was dropped in 1930. Three B-3A (LB-10A) were reengined with Wright R1750-3s and redesignated Y1B-5s. In 1930, twenty-seven B-3As were convereted to the B-5A design. They provided the backbone of the U.S. bomber force from then to 1934.
Operational history
The B-5A was the first line bomber of the United States Army Air Corps between 1930 and 1934. They remained in service until the early 1940s, serving primarily as observation aircraft.
