The Nakajima E2N was a Japanese reconnaissance aircraft of the inter-war years. It was a single-engine, two-seat, sesquiplane seaplane with twin main floats.
Design and development
[edit]The E2N was developed in the 1920s for the Imperial Japanese Navy as a short range reconnaissance floatplane suitable for catapult launch from cruisers and battleships.[1] It was a wooden, twin-float sesquiplane, carrying a crew of two in open cockpits and having folding wings. This layout gave better downwards view than the monoplanes proposed by Aichi and Yokosuka, and the design was selected becoming Japan's first locally designed shipboard reconnaissance seaplane.
Operational history
[edit]The E2N served with the Navy as the Nakajima Navy Type 15 Reconnaissance Floatplane (一五式水上偵察機). Eighty examples were produced between 1927-29 by Nakajima and Kawanishi; of these, two were bought for civil fishery patrol duties. The Navy machines were withdrawn from front-line units in the 1930s, being replaced by the Nakajima E4N, and either being reassigned to training duties or sold to civil buyers.
