History
Manufactured1927
Introduction date1925

Originally designed for land-based use, the Model 34C was virtually identical to the P-1 Hawk in United States Army Air Corps service. The United States Navy ordered nine, but starting with the sixth example, they were strengthened for carrier-borne operations and redesignated Model 34D. Flown from the carriers Langley and Lexington from 1927–30, most of the later variants passed to Marine fighter-bomber units, while a few were flown for a time as twin-float floatplanes.
