Aichi E10A

In 1934, based on experience of testing the Experimental 6-Shi Night Reconnaissance Flying boat, the Imperial Japanese Navy drew up a specification for a new night reconnaissance aircraft, intended to shadow enemy fleets during the cover of darkness, with orders being placed with Aichi and with Kawanishi.

Aichi’s design, with the company designation AB-12, was a single-engined biplane flying boat of all-metal construction.

 Its two-bay wings folded rearwards to save space on board ship, while its crew of 3 were accommodated in an enclosed cabin.

 It was powered by a pusher water-cooled Aichi Type 91 engine, driving a four-blade wooden propeller.

The first prototype flew in December 1934, and when tested proved to have superior stability to the competing Kawanishi E10K, and so was ordered into production.

The AB-12 entered service in August 1936 with the Japanese Navy as the Type 96 Night Reconnaissance Seaplane, with the short designation E10A.

Fifteen aircraft were built, remaining in service until 1941, being phased out before the Japanese Attack on Pearl Harbor.


The Aichi E11A was an Imperial Japanese Navy flying boat used during the first year of World War II for maritime patrol duties.

The Allied reporting name for the type was “Laura”; the Japanese Navy designation was “Type 98 Reconnaissance Seaplane”.

The Type 98 was quite similar to the earlier E10A Type 96, whose allied name was “Hank”. “Lauras” were rare – only 17 were built.

 It was designed to be launched from cruisers or battleships in order to spot their shellfire at night.

The Type 98s were soon diverted to communications and transport duties.
