09/30/2014. Remarks by Johan Visschedijk: "The Model 69, tested by the USN as XF2B-1 and put into production as F2B-1, was a direct development of the XP-8 using the power plant installation developed by the Navy on the FB-6. Fuselage structure differed slightly from the XP-8 in that the vertical and diagonal tubes aft of the cockpit were bolted to tabs welded to the longerons. As in the XP-8, wire was retained only for side-to-side bracing within each bay and a center section for the two lower wing panels was built below the lower longerons. The rudder was unbalanced. Power plant was a 425 hp Pratt & Whitney R-1340 Wasp radial. Armament consisted of a 0.30 in (7.62 mm) machine gun and a 0.50 in (12.7 mm) machine gun, or two 0.30 in (7.62 mm) machine guns, while additionally five 25 lb (11 kg) bombs could be carried.

The single-seat prototype shipboard fighter first flew on November 3, 1926, and received the Navy designation of XF2B-1, the Navy having just adopted the Army practice of identifying experimental prototypes with the letter X placed before the model designation. The nose of the XF2B-1 was faired with a large propeller spinner similar to that of the original FB-4 installation but the feature was not adopted for the production models."
