The J3s
were a purely
Japanese design incorporating a seaplane hangar sunk into the deck
casing. Though designated as long-range cruising submarines (Junyo
sensuikan), they were based less on the J2
class than on the KD series of classes. Their design included facilities allowing them to operate as flagships for squadron commanders. Completed in 1937-1938, they were the largest and most capable submarines developed by the Japanese prior to war.
