This is the Mid-Atlantic Air Museum's beautifully restored N3N-3 Yellow Peril/Canary trainer.
The N3N was a United States two-place primary training biplane aircraft built by the Naval Aircraft Factory (N.A.F.) in Philadelphia, Pennsylvania during the 1930s.
The N.A.F. delivered over 900 N3N aircraft beginning in 1935. Of these were N3N-1s and over 750 were N3N-3s. Four N3N-3s were delivered to the United States Coast Guard in 1941. Production ended in January 1942 but the type remained in use through the rest WW II. The N3N was the last biplane in US military service - the last (used by the U.S. Naval Academy for aviation familiarization) were retired in 1961. The N3N was also unique in that it was an aircraft designed and manufactured by an aviation firm wholly owned and operated by the U.S. government (the Navy, in this case) as opposed to private industry. Two-seat primary trainer biplane, powered by a 235-hp (175-kW) wright R-760-2 Whirlwind 7 radial piston engine. 816 built.
