Boeing P 12E & Boeing P 26A
P-12 was one of the most successful American fighters produced between WW
I and WW II. Used by both the Army and Navy (as the F4B), the P-12 was
developed from prototypes built by the Boeing Airplane Company at their
own expense. It was produced in a basic version and five additional
series, -B through -F. The basic P-12 and the -B, -C and -D series had
fabric-covered fuselages of bolted aluminium tubing. P-12E and -F
fuselages were all-metal, semi-monocoque (stressed skin) construction. All
had wooden wings with fabric covering. The Army Air Corps received its
first P-12 in Feb. 1929 and the last P-12F in May 1932. The last of the
biplane fighters flown by the Army; some remained in service until 1941.
In all, 366 were produced for the Army. More P-12Es were built (110) than
any other series.
