Operational history

The N.A.F. built 997 N3N aircraft beginning in 1935. They included 179 N3N-1s and 816 N3N-3s, plus their prototypes. Production ended in 1942, but the type remained in use through the rest of World War II. The N3N was the last biplane in US military service - the last (used by the
