Aichi E13A

The Aichi E13A served as a long-range reconnaissance seaplane for the Imperial Japanese Navy from 1941 to 1945.

As the IJN’s most numerous floatplane, it had the capacity to transport a crew of three and a bomb payload of 250 kg (550 lb).

Its official designation was “Navy Type Zero Reconnaissance Seaplane.”

In China, it was deployed from seaplane tenders and cruisers.

Subsequently, it played a scouting role in the attack on Pearl Harbour and was engaged by the United States Navy during the Battles of Coral Sea and Midway.

The aircraft was operational throughout the conflict, performing coastal patrols, navigation strikes, liaison, officer transport, and castaway rescues, among other missions, and even participating in kamikaze missions during the war’s final days.

The German base at Penang operated one Aichi E13A alongside two Arado Ar 196s, forming the East Asia Naval Special Service to support the German Monsun Gruppe and local Japanese naval operations.

The French Navy Air Force utilised eight examples during the First Indochina War from 1945 to 1947, and it is believed that the Naval Air Arm of the Royal Thai Navy operated some before the war.

One E13A was handed over to New Zealand forces following the cessation of hostilities.

It was operated for a short time by RNZAF personnel but was not restored after sustaining damage to a float, leading to its sinking at the moorings in Jacquinot Bay.
