The Nakajima E4N was a Japanese shipboard reconnaissance aircraft of the 1930s. It was a two-seat, single-engine, equal-span biplane seaplane used primarily by the Imperial Japanese Navy.

Development

The first prototype of the Type 90-2 Reconnaissance Seaplane, or E4N1, flew in 1930. This was fitted with twin floats and had no cowling for the engine. This prototype was rejected. The type was completely redesigned as the Type 90-2-2 or E4N2, with a single main-float and twin, wing-mounted outriggers and introduced a cowled engine. This entered production for the Navy in 1931. A landplane version of the Type 90-2-2 was developed as the E4N2-C with a tailwheel undercarriage

Operational history

The E4N2 was employed as a shipboard reconnaissance seaplane launched by catapult. In 1933, nine E4N2-C airframes were converted to P1 mail planes. Single-seat landplanes with an enclosed cockpit, these were employed on night-mail services between the Japanese Home Islands.
