Authorized in the "First Replenishment Program" of 1931, the Type J2 was similar to the Type J1M, except in having more powerful engines, a slightly longer hull, and somewhat less range. The Type J2 definitely had a catapult aft, with the aircraft being launched astern.

The I-6 was the only ship of this type, but she was very active. Patrolling off Oahu at the start of the war, she damaged aircraft carrier USS Saratoga on 11 January, 1942, removing that valuable warship from the US Pacific Fleet's roll call for a very critical six month period. I-6 made one patrol off the coast of Java in early 1942, then performed reconnaissance off the western coast of India in April 1942. She sank two cargo vessels in each of these missions, including 5,897-ton Clan Ross and the 5,424-ton Bahadar off Bombay. She patrolled Aleutian waters in late 1942, then laid mines, including six acoustic mines received from Germany, off Brisbane, Australia on 13 March 1943. Allied naval intelligence knew of this mission in advance Three American submarines waited in ambush, but none sighted I-6 that night.

I-6 was sunk in a collision with the freighter TOYOKAWA MARU on 16 June 1944.

The combined fleet site has this short biography on the I-6 if it would be of any use. Apparently, she was the only Type J2 built.

back to the game do you think get a fp one the ss a good idea? with most ss (I class) deploy around LA for cutting fuel transportation?

It's always nice to have a float plane onboard, but my own small experience with operating Japanese submarines close-in off US West Coast cities is that it is a tough neighborhood to play in. The enemy can swamp your possible location pretty quickly with everything from freshly constructed first-line destroyers to lowly yard patrol vessels. Aerial patrols are plentiful too. If you get damaged, it's a long trip home to the Japanese Mandates even. This tends to make you patrol further out in the deep Pacific where there are no good choke points and you have to trust to luck for sinking tankers and merchantmen.

But maybe someone with more experience in the department will chime in.

A rather ignominious ending for an impressive ship. A very shameful display!

in the history, 6th fleet did assault west coast for a short period after hawaii but had little effect. many I captains wants to use their subs sink cargo ships but were forbiden from combined fleet. even americans were curious why japanese did not do what germans did. it is interesting to perform their ideas historicly.
