I-365 was an Imperial Japanese Navy Type D1 transport submarine. Completed and commissioned in August 1944, she served in World War II and was sunk while returning from her first transport mission in November 1944.

Construction and commissioning[]

I-365 was laid down on 15 May 1943 by the Yokosuka Navy Yard at Yokosuka, Japan, with the name Submarine No. 5465.[2] She was renamed I-365 on 20 October 1943 and provisionally attached to the Yokosuka Naval District that day.[2] She was launched on 17 December 1943[2] and was completed and commissioned on 1 August 1944.[2]

Service history[]

Upon commissioning, I-365 was attached formally to the Yokosuka Naval District and was assigned to Submarine Squadron 11 for workups.[2] With her workups complete, she was reassigned to Submarine Squadron 7 on 30 September 1944.[2]

On 1 November 1944, I-365 departed Yokosuka bound for Truk on her first transport mission, carrying a cargo of mail and medicine.[2] She reached Truk on 15 November 1944, unloaded her cargo, and embarked 31 passengers. She got back underway on 16 November 1944 with total of 96 passengers and crew aboard bound for the Bonin Islands, intending to proceed to Yokosuka after her stop in the Bonins.[2] She sent a routine signal on 25 November 1944 while east of the Bonins.[2] The Japanese never heard from her again.[2]

On 29 November 1944, the United States Navy submarine USS Scabbardfish (SS-397) sighted I-365 with her high periscope while I-365 was on the surface in the Pacific Ocean 75 nautical miles (139 km; 86 mi) southeast of Yokosuka.[2] Scabbardfish tracked I-365 for three hours before a Japanese aircraft forced her to submerge, but she surfaced and completed an "end-around" maneuver in which she outran I-365 and submerged in a favorable firing position in front of I-365.[2] Scabbardfish launched two torpedoes from her stern torpedo tubes at a range of 1,625 yards (1,486 m).[2] At 09:40, one of them hit I-365, exploding on her starboard side in her forward battery compartment.[2] I-365 sank in 30 seconds at

On 10 December 1944, the Imperial Japanese Navy declared I-365 to be presumed lost off the Bonin Islands.[2] She was stricken from the Navy list on 10 March 1945.[2]
