P-12B apply a part of the modification of the XP-12A, wings type Frise and modified elevator. The engine but remained without the fairings have been removed and the aerodynamic transitions for a cylinder of the engine, used on the P-12. Undercarriage legs remained unchanged, P-12B, but got the wheels of slightly larger dimensions, 30x5 in place of the original 28x4 in. 10. June 1929 was ordered 90 of the machines (factory designation Model 102B, serialy 29-329/341, 29-433/450 and 30-029/087), which accounted for the biggest purchase of the USAAC after 1. world war. P-12B retain the R - 1340-9, the increase in the total weight but caused a noticeable drop in performance against the "předsérii" P-12 and XP-12A. The first machines got to the troops in the spring of 1930, served for example at 55. fighter squadron at the california base, Mather Field, or 14. fighter squadron at Bolling Field on the outskirts of Washington. Later in life, most of the machines got the motor the rings Townsend and rudder of the P-12E.
One P-12B, 29-329, later, the army adjusted the development of the experimental engine Y1SR-1340G and later H, equipped with a compressor and a narrow ring covering the engine. This machine was given the designation XP-12G, after the end of the tests was returned to its original form..
