Japanese submarine I-157
I-57, later I-157, was an Imperial Japanese Navy Kaidai-class cruiser submarine commissioned in 1929. During World War II, she supported Japanese forces during the invasion of Malaya in December 1941, the Dutch East Indies campaign in early 1942, and the Battle of Midway in June 1942. She then served on training duties — except for a brief period of participation in the Aleutian Islands campaign in 1943 — until she was converted into a kaiten manned suicide attack torpedo carrier in 1945. She surrendered to the Allies at the end of the war in 1945 and was scuttled in 1946.
The submarines of the KD3B sub-class essentially were repeats of the preceding KD3A sub-class with minor modifications to improve seakeeping. They displaced 1,829 metric tons (1,800 long tons) surfaced and 2,337 metric tons (2,300 long tons) submerged. The submarines were 101 meters (331 ft 4 in) long and had a beam of 8 meters (26 ft 3 in) and a draft of 4.9 meters (16 ft 1 in). They had a diving depth of 60 meters (197 ft) and a complement of 60 officers and crewmen.
For surface running, the submarines were powered by two 3,400-brake-horsepower (2,535 kW) diesel engines, each driving one propeller shaft. When submerged, each propeller was driven by a 900-horsepower (671 kW) electric motor. The submarines could reach 20 knots (37 km/h; 23 mph) on the surface and 8 knots (15 km/h; 9.2 mph) submerged. On the surface, the KD3Bs had a range of 10,000 nautical miles (19,000 km; 12,000 mi) at 10 knots (19 km/h; 12 mph); submerged, they had a range of 90 nmi (170 km; 100 mi) at 3 knots (5.6 km/h; 3.5 mph).
The submarine had eight internal 53.3 cm (21 in) torpedo tubes, six in the bow and two in the stern. They carried one reload for each tube for a total of 16 torpedoes. They also had one 120 mm (4.7 in) deck gun.
Built by the Kure Naval Arsenal at Kure, Japan, I-57 was laid down on 8 July 1927. Launched on 1 October 1928, she was completed and commissioned on 24 December 1929.
On the day of her commissioning, I-57 was attached to the Kure Naval District and assigned to Submarine Division 19 in Submarine Squadron 2 in the 2nd Fleet, a component of the Combined Fleet. She was placed in reserve at Kure on 15 November 1930, but returned to active service on 14 November 1931. On 1 December 1931, Submarine Division 19 was reassigned to the Kure Defense Division in the Kure Naval District.
On 20 May 1932, Submarine Division 19 began a second stint with Submarine Squadron 2 in the 2nd Fleet, but on 1 June 1932 I-57 again was placed in reserve at Kure. She returned to active service in her division on 5 October 1932. I-57 got underway from Sasebo, Japan, on 29 June 1933 with the other submarines of her squadron — I-53, I-54 and I-55 of Submarine Division 18 and Submarine Division 19′s I-56 and I-58 — for a training cruise off China and Mako in the Pescadores Islands, which the submarines concluded with their arrival at Takao, Formosa, on 5 July 1933. They departed Takao on 13 July 1933 and again trained in Chinese waters before arriving in Tokyo Bay on 21 August 1933. On 25 August 1933, all six submarines took part in a fleet review at Yokohama, Japan. On 27 September 1934, I-57 departed Ryojun, Manchukuo, in company with I-56, I-58, and the submarines I-61, I-62, I-64, I-65, I-66, and I-67 for a training cruise off Qingdao, China, which the nine submarines concluded with their arrival at Sasebo on 5 October 1934. I-57 again went into reserve at Kure on 22 October 1934, and on 15 November 1934 Submarine Division 19 was reassigned to the Kure Guard Squadron in the Kure Naval District.
I-57 resumed active service in Submarine Division 19 on 15 November 1935, and that day Submarine Division 19 was reassigned to Submarine Squadron 1 in the 1st Fleet, a component of the Combined Fleet. On 1 December 1936, Submarine Division 19 was reassigned to the Kure Naval District, in which it was placed in the First Reserve on 7 January 1937. The division returned to active service in the district on 1 January 1938, but was placed in Third Reserve on 15 December 1938, and I-57 went into reserve at Kure that day.
