The Aichi E13A (Allied reporting name: "Jake") was a long-range reconnaissance seaplane used by the Imperial Japanese Navy (IJN) from 1941 to 1945. Numerically the most important floatplane of the IJN, it could carry a crew of three and a bombload of 250 kg (550 lb). The Navy designation was "Navy Type Zero Reconnaissance Seaplane" (零式水上偵察機).

In China, it operated from seaplane tenders and cruisers. Later, it was used as a scout for the Attack on Pearl Harbor, and was encountered in combat by the United States Navy during the Battles of Coral Sea and Midway. It was in service throughout the conflict, for coastal patrols, strikes against navigation, liaison, officer transports, castaway rescues, and other missions, along with some kamikaze missions in the last days of war.

Eight examples were operated by the French Navy Air Force during the First Indochina War from 1945-1947,^[1] while others were believed to be operated by the Naval Air Arm of the Royal Thai Navy before the war. One example captured by New Zealand forces was flown by RNZAF personnel in theatre, but sank and was not repaired after a float leaked.

Surviving aircraft

The wrecks of a number of sunken aircraft are recorded. The wreckage of one aircraft is located on-land at an abandoned seaplane base at Lenger Island, off Pohnpei in the Federated States of Micronesia.^[5]

One E13A was raised from where it sank and is displayed at the Kakamigahara Aerospace Museum, Kakamigahara, Gifu, Japan. However, it is reportedly in poor condition, lacking its engine, tail floats and one wing.^[6]
