81 nautical miles and 323 degrees NW of Naha, Okinawa. Alerted by a code-breakers ULTRA message from COMSUBPAC, LtCdr Frederick A. Gunn's (USNA '34) USS SCABBARDFISH (SS-397) intercepts JINGEI. Gunn sets up and fires four torpedoes. At 0915, two torpedoes hit JINGEI starboardside in her bow at 27-35N, 127-07E. JINGEI engine room, No. 2 and No. 3 boiler rooms and generator room flood. She goes dead in the water, unnavigable, with her bow almost under water.

Bogan's TG 38.2, Rear Admiral Frederick C. Sherman's TG 38.3 and Rear Admiral Ralph E. Davison TG 38.4 attack shipping and installations on Okinawa as a prelude to the landings at Leyte.
NNW of Okinawa, off Nago Bay. Stationary JINGEI, still at anchor and unnavigable, is attacked by aircraft from TG 38.2's USS HANCOCK (CV-19).

Exactly 100 men are killed, but the number of wounded is unknown. Captain Oyama survives the sinking.
Subchaser KAII, trying to escape from Naha Harbor, is strafed and bombed, set afire, floods and beached in shallows off Naha and abandoned.
