Spot it by:

Distinguished from the F4B-1 by its Townend ring cowling and split-axle gear; from the later F4B-4 by the fabric-covered fuselage rather than a metal monocoque. The unequal-span biplane wings and compact Wasp radial give it a purposeful, clean appearance against more angular contemporaries.

History

Boeing developed the F4B series from its Model 83/89 private-venture designs in the late 1920s, producing a succession of progressively refined variants for the US Navy. The F4B-2, delivered from 1932, featured an improved ring cowling, split-axle undercarriage and revised cockpit over the F4B-1. The Army Air Corps received essentially the same aircraft as the P-12E.

Variants

The F4B family ran from F4B-1 through F4B-4, each incorporating incremental aerodynamic refinements; the F4B-4 featured a metal monocoque fuselage replacing earlier fabric-over-frame construction. Export customers included Brazil and Thailand.

Where you'll see it

The F4B-2 equipped US Navy squadron VF-6 aboard USS Saratoga and VF-1 aboard USS Langley, serving as the Navy's primary shipboard fighter until the biplane era ended with the arrival of monoplanes in the mid-1930s.
