Japanese submarine Ro-102
Completed and commissioned in November 1942, she served in World War II, operating in the Solomon Islands, Rabaul, and New Guinea areas.[5] After the Combined Fleet initiated Operation I-Go — a reinforcement of the 11th Air Fleet base at Rabaul by planes from the aircraft carriers Zuikaku and Zuihō and of the Japanese naval air base on Balalae Island in the Shortland Islands by planes from the aircraft carriers Hiyō and Jun'yō.[5] — Ro-102 departed Rabaul on 30 March 1943 in company with the submarine Ro-103 to support the operation by patrolling southeast of Guadalcanal.[5] She transmitted a message on 9 May 1943 from a position south of New Guinea reporting a lack of enemy activity in the area.[5] On 2 June 1943, the Imperial Japanese Navy declared Ro-102 to be presumed lost south of Rabi with all 42 men on board.
