The I-5 was an experimental
one-off development of the J1s (J1M class) that originally
included a catapult and two watertight deck tubes containing the
fuselage and wings of a seaplane.
The aircraft
had
to be
assembled from
the tubes while the submarine was surfaced, leaving the submarine
highly
vulnerable to attack. There was also no catapult for launching the
aircraft and the handling arrangements were unsatisfactory. However,
the Japanese believed the seaplane-equipped scouting submarine concept
had
great
promise.
The seaplane provisions were eliminated in 1940,
leaving the I-5 little
different from other J1s.
I-5 was deployed east of Oahu when war broke out, and was sunk on 19 July 1944 off Guam by Wyman.
