Between 1929 and 1932, the Army Air Corps received a total of 366 P-12s produced in six basic models: P-12 and series -B through -F. The P-12 was developed by Boeing, at their own expense, as the Model 89. The P-12 was also flown by the Navy as the F4B. Boeing used experienced gained during the construction of the XP-9, to develop a semi-monocoque all-metal fuselage version of the P-12 (Boeing Model 218). The Model 218 was tested with the designation XP-925 and resulted in an order for 135 more P-12s (-E and -F models).

The National Museum of the United States Air Force has a P-12E on display in its Early Years Gallery.
