The Kawanishi E7k (Allied code name "Alf") was a for reconnaissance purposes constructed seaplane of the Imperial Japanese Navy in World War II . The Imperial Navy led the aircraft as a Marine Type 94 sea reconnaissance aircraft ( Japanese 九四 式 水上 偵察機) .
history
In 1932, the Imperial Japanese Navy put out an order for the development of a new, ship-based seaplane for reconnaissance purposes. Kawanishi developed the E7K1, equipped with a Type 91 W engine with 441 kW (600 hp). The Navy tried the model from February 1933 and decided to order the E7K1 . From 1935 the aircraft type was introduced to the armed forces. From 1938 onwards, the engines produced by the Hiro company were replaced in a new batch with the designation E7K2 by radial engines from Mitsubishi with 649 kW (870 hp) due to lack of reliability . The revised type was introduced as the Marine Type 94 Sea Reconnaissance Model 2 .
In the Pacific War , the E7K was not up to the service at the front and was only used in rear units from 1943.
