Boeing XF6B-1 / Model 236

The last Boeing fighter of biplane configuration, the Model 236 single-seat shipboard fighter was designed around the 14-cylinder two-row Pratt & Whitney R-1535 Twin Wasp Junior engine rated at 625hp at 1676m. Of all-metal construction with fabric-covered wings, the Model 236 was assigned the designation XF6B-1 by the US Navy and flew on 1 February 1933. Armament comprised two 7.62mm guns and provision was made for a single 227kg bomb or two 52kg bombs, and on 21 March 1934, the prototype was assigned the new "bomber-fighter" designation of XBFB-1. The engine installation and undercarriage were refined during the test and evaluation programme, but no production was undertaken.

Its American pilot scrambled to intercept Japanese fighters in 1935-37 and was shot down.

I believe one of these MAY have been demonstrated to the Nationalist Chinese government some time in the 1930s. Its American pilot scrambled to intercept Japanese fighters in 1935-37 and was shot down.

I think the F6B-1 is the finest looking Bi-Plane of all.
