[1] [ROBALO's report says the position was 10-29'N, 109-26'E 60 miles from the coast. The second bomb from KAIYO's plane exploded close aboard to port when the sub had only reached 55 fee and caused considerable damage. The SJ radar and JP Sound gear was knocked out, periscopes damaged, conning tower hatch sprung, and hydraulic steering damaged among others. The submarine had in fact completely evaded the depth charge attack that followed not even reporting it; all the damage had been due to the aircraft's bomb. At 2013 (HOW-time/= 2113 Item time) ROBALO had surfaced. After temporary repairs, she aggressively remained on patrol.]
[2] Somes sources credit AWAJI's sinking to Haskins' GUITARRO (SS-363). This is likely incorrect. A closer look reveals the following. Shortly before 0245 2 June AWAJI reported an enemy sub detected, but then was torpedoed and sunk. At 0147 (How Time) 2 June while closing a convoy contact GUITARRO sighted a torpedo hit on a target by another sub. These leave little doubt that AWAJI was sunk by PICUDA. GUITARRO had closed, sighting a burning ship at 0302 (H-time). (This is probably ARIMASAN MARU with fire burning on forecastle.) She herself makes her attack at 0419 (H-time) with four torpedoes. Three hits were claimed with a tremendous explosion, but a torpedo made a circular run and forced the sub deep for half and hour. Coming back up to periscope depth at 0505 (H-time) all hands took turns watching this target sink in two sections. Then,the evening of the same day 2 June, at 2230 (H-time) GUITARRO claimed to have torpedoed and exploded a MINEKAZE-class DD. However, the target was apparently CD-19 which was missed by two torpedoes that exploded against the shoreline shortly before midnight. She dropped seventeen depth-charges, then at 0045 3 June resumed heading for Keelung to join KASHI.
[3] KAIYO carried 65 Mitsubishi A6M "Zeke" fighters, 55 Yokosuka D4Y "Judy" bombers and 10 transports of unknown type. This large number of aircraft suggests that most, if not all, were carried disassembled, probably in crates.
[4] This towing of KAIYO by destroyer YUKAZE incidentally, is the only Japanese carrier successfully towed to refuge by a destroyer. Japanese praised the action, for KAIYO was "ten times the size" of little YUKAZE, an elderly destroyer, at that. DesDiv 17's ISOKAZE and HAMAKAZE had between them taken torpedoed SHINANO in tow briefly, but had to abandon the attempt.
[5] This bit of data from CNO damage summaries of intercepts post-war, provided courtesy of John Whitman, is important. Though little more than a fragment, it affirms that KAIYO remained manned till just after the Fifth Air Force's attack by B-25s. Indeed, it shows that the raid played a role in her final total loss. (Col. Hawes posthumously received the Distinguished Flying Cross.)
[6] Some postwar sources use the phrase "capsized and sunk" or just "capsized" for the state of KAIYO. This is technically incorrect. KAIYO never had a list greater than 20 degrees to port, even as a wreck to the time of refloating and salvage of the hull, and can be regarded as "bottomed while upright". It is worth noting that inspection photos of KAIYO bottomed show the flight deck well clear of the water but with a port list.
