The Boeing F4B/P-12 series served as the primary fighter of the U.S. Navy and U.S. Army Air Corps in the early 1930s, and it remained in service in numerous roles until the early 1940s. It was the last wooden-winged, biplane fighter produced by Boeing and used by the U.S. military. Highlighted in this image are the propeller and landing gear on the Boeing F4B-4.
