Super easy search engine topic. Just typed in "B-10 bomber" and all sorts of stuff comes up.
The B-10, the first of the "modern-day" all-metal monoplane bombers to be produced in quantity, featured such innovations as internal bomb storage, retractable landing gear, a rotating gun turret, and enclosed cockpits. It was so advanced in design that it was 50% faster than its contemporary biplane bombers and as fast as most of the fighters. When the Air Corps ordered 121 B-10s in the 1933-1936 period, it was the largest procurement of bomber aircraft since WW I. It also ordered 32 B-10 type bombers with Pratt and Whitney rather than Wright engines and designated these B-12s.
General Henry H. "Hap" Arnold once called the B-10 the air power wonder of its day. In 1934, he led ten B-10s on a 8,290 mile flight from Washington, D.C. to Fairbanks, Alaska and back. Although Air Corps B-10s and B-12s were replaced by B-17s and B-18s in the late 1930s, China and the Netherlands flew export versions in combat against Japan.
The aircraft on display is painted as a B-10 used in the 1934 Alaskan Flight. The only remaining B-10 known, it was an export version sold to Argentina in 1938. Donated by the Government of Argentina to the U.S. Government for the Air Force Museum in 1970, it was restored by the 96th Maintenance Squadron.
