"I" Boats - Long range fleet submarines. Almost half carry aircraft at the start.
These were observed to carry a seaplane: I-7, I-9, I-10, I-19, I-21, I-25, I-26, and in SW Pac: I-29, I-30. These were designed to carry an aircraft, although a few traded the seaplane for a second deck gun : I-5 to I-11, I-13 to I-15, I-17, I-19, I-21, I-23, I-25 to I-45, I-54, I-56, I-58 . Most other subs were fitted to carry mini-subs.
I-201 to I-203 were snorkle equipped and came late in the war, 1945.
I-361 to I-373 were transport subs, 1944.
I-400 to I-402 were supersubs to carry three aircraft each to strike the Panama Canal, 1945.
I-501 to I-506 were Axis provided submarines.
RO- designation was for shorter range submarines ; about 50 subs.
Ha- indicated coastal boats including :
Midget-subs: 46 tons, 80 feet long, 6 feet diameter, 2 torpedoes, 16 hour range.
Two sizes of new mini-subs were building for the final defense of the home island at the end.
"Most of the submarines departed from JAPAN for a rendezvous at KWAJALEIN,
to proceed thence to HAWAII. A few, which were delayed in leaving JAPAN,
changed course and proceeded directly to HAWAII.
The submarines continued operations in the vicinity of HAWAII from 8 December, the day of the attack, until early January of the following year. During this time, most of the submarines proceeded to the west coast of the UNITED STATES to destroy shipping, and part of the submarines returned to JAPAN. Only a small number remained in the Hawaiian area for the maximum length of time.
"The Japanese submarine detachment belonged to the Sixth Fleet, whose flagship was the light cruiser Katori. In early November orders for war preparation were given to this detachment, and on 11 November over ten submarines of the First and 3rd Detachments, including "I" Nos. 69, 74, 75 and others left Yokosuka Naval Base, with knowledge of the growing war fever in Washington and Tokyo.
"The submarine fleet followed a course due east in line ahead, stretching over 20 miles. They navigated at surface speeds of from 12 or 13 to 20 knots. But when they got near the Hawaiian waters they extended and followed their respective courses. The duties of the submarine fleet were known as
"The surprise attack on Pearl Harbor was carried on as had been scheduled. Before this, five large sized "I" type submarines belonging to the First Submarine Detachment had launched "special submarines" from their decks. That was the departure of the now well known Commander Iwasa and other members of "special attack parties".
"The submarines followed the upheaval in the harbor only through occasional land explosions coming through the deep water, and they confirmed the Harbor Battle at night when they emerged from the bottom of the sea. At 1631 (2101 Hawaiian time) Rear Commander Watanabe of "I No. 69" detected from the periscope a huge fiery column which marked the end of the USS Arizona.
"Lt. Commander Watanabe's radio intercepted dispatches in relation to this were by the enemy and his "I No. 69" was pursued by enemy destroyers which dropped depth charges madly. Under this circumstance "I No. 69" dived 60 to 70 meters beneath the surface, though her ordinary diving capacity had been set at 30 meters. The submarine sustained damage here and there and finally was caught by submarine wires. She struggled hard and just managed to get away from the wires. Altogether this old submarine remained submerged about 39 hours. All hopes of rescuing fellow-fighters who had been shot down had been abandoned."
The notes from direct narration by Captain Watanabe and Rear Admiral Nakaoka end here.
Capt Watanabe perished with his submarine in 1943 around the Gilbert Islands.
RAdm Nakaoka was killed while captain of the crack cruiser Atago.
