P-12

Developed by the Boeing Aircraft Co. at its own expense, the P-12 was became one of the most successful American fighters produced between the World Wars. Flown by both the Army and the Navy (as the F4B), the P-12 series consisted of an initial version and five additional models, B through F. The early versions used fabric-covered fuselages of bolted aluminum tubing, but the P-12E and F fuselages employed an all-metal, semimonocoque (stressed skin) construction. However, the P-12 did not complete the evolution into an all-metal aircraft because all variants had wooden wings with fabric covering.

The U.S. Army Air Corps received its first P-12 in February 1929 and the last P-12F in May 1932. The last of the biplane fighters flown by the Army, some P-12s remained in service until 1941. Boeing produced 366 P-12s for the Army, with more P-12Es built (110) than any other series.
