31 August 1944:
Luzon Strait, S of Formosa. At about 0220, LtCdr (later Rear Admiral) Charles E. Loughlin's (USNA ‘33) USS QUEENFISH (SS-393) hits CHIYODA MARU with four torpedoes and sets her afire. At 0240, as the moon sets, CHIYODA MARU sinks. She was carrying 430 passengers, coal briquettes and drummed gasoline. 382 passengers and 15 of the crew are KIA. Loughlin also damages oiler RIKKO MARU steaming in ballast.
LtCdr (later Vice Admiral) Eli T. Reich's (USNA ‘35) USS SEALION (SS-315), a member of "Ben's Busters" with GROWLER (SS-215) and USS PAMPANITO, enters the Bashi Strait. USS SEALION’s SJ radar picks up the convoy and Reich makes a night surface approach. He sets up and fires six torpedoes, but they all run erratically. About 0500, Reich swings USS SEALION and fires his four stern torpedoes at a large tanker. He claims two hits.
Alerted by code-breaker's "Ultra" signals, LtCdr (later Rear Admiral) Eugene B. Fluckey's (USNA ‘35) USS BARB (SS-220) intercepts the convoy. At about 0700, Fluckey torpedoes OKUNI MARU. She sinks stern first. Three men are KIA. Fluckey also sinks the 45th Minesweeper Squadron's HINODE MARU No. 20 that was patrolling in the area. Two crewmen are KIA.
USS SEALION evades the convoy's escorts. Still surfaced, LtCdr Reich makes an “end-around” approach and works his way ahead of the convoy. At 0715 (JST), SHIRATAKA's lookouts spot a submarine on the surface at at 21-05N, 121-26E. Reich misidentifies SHIRATAKA as a destroyer. He then begins a submerged approach. At 0730, Reich hits SHIRATAKA with two of three torpedoes he fires.
At 1115, SHIRATAKA sinks at 20-55N, 121-07E. Captain Miki Takahide is KIA. He is promoted Rear Admiral, posthumously.
Japanese planes begin circling the area and surface escorts search for the submarine. Reich takes USS SEALION deep and later makes port at Saipan to replenish torpedoes and fuel.
10 October 1944:
Removed from the Navy List.
*E = estimated date.
 Sometime during the war, SHIRATAKA's 120-mm guns were landed and new 3-inch (76-mm)/40 3rd Year Type main guns and 25-mm Type 96 AA were fitted. She also received a radar (probably Type 22), sonar and more depth charges.
 The use of warships as cargo carriers was indicative of the shortage of suitable ships and the backlog of cargo beginning to be felt across the Empire.
Thanks for assistance go to Jean-Francois Masson of Canada, Gilbert Casse of France, John Whitman of USA and Allan Alsleben of Oregon. Special thanks go to Hans Mcilveen of the Netherlands for info on FRUMEL intercepts.
