28 November 1942:
26 January 1943- 1 January 1944:
Sasebo Navy Yard. Undergoes
conversion to a conventional aircraft carrier.
Sources vary concerning the configuration of CHITOSE, CHIYODA, NISSHIN and MIZUHO. All were constructed as seaplane carriers capable
of carrying 24 floatplanes. CHIYODA was later converted to enable her to carry 12 midget submarines. This modification reduced her floatplane capacity to 12 aircraft. NISSHIN, completed during wartime, was constructed as a seaplane/midget submarine carrier. While it has been suggested that CHITOSE and MIZUHO also carried midget submarines, Japanese sources do not support that
 Author Henry Sakaida credits PO Katsuki Kiyomi with the kill.
 In December 2008, the remains of USS POPE (DD-225) was located in the Java Sea in approx 105 feet/32 meters of water by owner/skipper Vidar Skoglie’s dive vessel MV EMPRESS operating out of Singapore. The old destroyer appears to have been found earlier by Indonesian salvage divers and very little remains but a rusted iron ‘skeleton’.
 Five surviving members of 44-P-12's aircrew were rescued at 1455 (local) 6 June by
PBY-5 of VP 23. But unfortunately one of them died the next day, bringing the total KIA to six. PBY 44-P-12 was the only PBY lost in combat with Japanese forces during the battle of Midway.
 According to Sakaida, the B-17 was piloted by Lt David C. Everitt Jr. PO Katsuki survived the war. He became one of only two IJN floatplane aces
in WW2. His final score was 16 aircraft shot down, seven while he was flying floatplanes including F1M2, A6M2-N and N1K1s.
Thanks go to Tony Tully of Texas and Dr. Higuchi Tatsuhiro of Japan. Thanks also go to reader Mr. R Estey for his input on PBY P-12 at Midway. Thanks go to Peter Cundall of Australia for input for Rev 5, Allan Alsleben of Oregon, John Whitman of Virginia and Mssrs Takizawa Akira (Taki) and Fontessa of Japan for input for Rev 6.
