While Boeing manufactured the Thomas-Morse MB-3 for the Air Force, the PW-9 was the first fighter designed and built by Boeing. The FB was the Navy / Marine version and 27 FB-2s were the first Navy aircraft built specifically for carrier operations.

On display at the Steven F. Udvar-Hazy Center, National Air and Space Museum. The FB-5 was Boeing's first true carrier-borne fighter. This model saw service with VF-1 on USS Langley, VF-6B aboard USS Saratoga, VF-3B at San Diego and finally with Marine squadron VF-6M 'Red Devils'. Restoration of the aircraft was done by the USMC.

The Boeing 15 fighter served with the US Army as the PW-9 and with the Navy as the FB. The FB-5 model was the USN's first true carrier fighter. I understand it used 'grapple hooks' on an axle between the main wheels that this survivor doesn't have. The tail skid looks intriguing. Also the navigation light on the wing tip seems enormous, but this is mostly a wide angle effect.
