Ha-102 was an Imperial Japanese Navy Ha-101-class submarine. Completed and commissioned in December 1944, she served during the final months of World War II, making two supply runs. She surrendered at the end of the war in September 1945 and was disposed of in October 1945.
Design and description
The Ha-101-class submarines were designed as small, cheap transport submarines to resupply isolated island garrisons. They displaced 436 metric tons (429 long tons) surfaced and 501 metric tons (493 long tons) submerged. The submarines were 44.5 meters (146 ft 0 in) long, had a beam of 6.1 meters (20 ft 0 in) and a draft of 4.04 meters (13 ft 3 in). They were designed to carry 60 metric tons (59 long tons) of cargo.[1]
For surface running, the boats were powered by a single 400-

Service history
Upon commissioning, Ha-102 was assigned to Submarine Squadron 11 for workups.[4] In mid-January 1945 she conducted workups with her sister ships Ha-101 and Ha-104 in the Iyo Nada in the Seto Inland Sea.[4] She was reassigned to Submarine Squadron 7 in the 6th Fleet on 10 February 1945[4] and in mid-February 1945 departed Yokosuka, Japan, to take part in a series of exercises with Ha-101.[4]
Submarine Squadron 7 was disbanded on 20 March 1945, and Ha-101 was reassigned that day to Submarine Division 16 for supply operations.
Hostilities between Japan and the Allies ended on 15 August 1945, and on 2 September 1945, Ha-102 surrendered to the Allies at Yokosuka.[4] The Japanese struck her from the Navy list on 15 September 1945.[4] She was disposed of in Japan in October 1945; historians disagree on whether she was scrapped at Uraga Dockyard in Uraga or scuttled off Shimizu that month.[4]
