/ Boeing F2B
The Boeing Model 69, more commonly called the ‘’
’’ was a biplane fighter aircraft of the United States Navy in the 1920s.
First flight of the F2B prototype was November 3, 1926.
The Navy acquired the prototype as XF2B-1, which was capable of reaching speeds of 154 mph (248 km/h), and was sufficiently impressed to order 32 F2B-1s.
In addition to omission of the large streamlined spinner cap, the production versions also had a balanced rudder.
Delivery began on January 20, 1928, with some assigned to fighter squadron VF-1B and others to bomber squadron VF-2B, both operating from the carrier Saratoga.
