Introduced in 1929 in a call for a new attack plane, the aircraft was very advanced at the time, most other aircraft being biplanes. Thirteen went into service in 1932 but the type was quickly replaced by the radial engined version, the A-12 which was also obsolete before the end of the decade.
Enclosed cockpits were a modern feature, but the wings being externally braced with struts and wires was a throwback to an earlier era.
