Also known as the Type 0 Reconnaissance Seaplane, "Jake" was the
replacement for the E7K
"Alf"
and was the most numerous float plane produced by the Japanese.
Though lightly armed and unarmored, its long endurance suited its
role
as a patrol
reconnaissance and transport
aircraft. It was used in bombing
missions when no
enemy fighter opposition was
expected, as over China
early in the war.
The design was a response to a June 1937 call for
a two-seat replacement for the Alf. Aichi, Nakajima and Kawanishi
all
responded to the initial call, but when the Navy issued a new
specification for a three-seat reconnaissance seaplane, Kawanishi
decided to concentrate on completing its two-seat design instead.
Aichi
finished a prototype three-seater in late 1938 that proved
superior to
the Nakajima model, being faster, steadier, and more maneuverable,
though also larger and heavier. By then the Navy had lost interest
in
the two-seat designs, and "Jake" went into production in December
1940.
It saw its combat debut in late 1941 over the Canton-Hankow
Railway in China and scouted
for the
Pearl Harbor Attack Force.
Towards the end of the war, "Jake" was armed with a downward-firing 20mm Type 99 Model 1 cannon for use against PT boats. It also was sometimes equipped with Type 6 radar or with the Jikitanchiki magnetic anomaly detector for use against submarines. The Jikitanchiki was not very sensitive, requiring the plane to fly no more than 40 feet above the surface.
