The Japanese submarine I-179 (originally I-79) was a
Kaidai type cruiser submarine of the KD7 sub-class built for the Imperial Japanese Navy (IJN) during the 1940s. She was lost with all hands when a valve was accidentally left open during her sea trials in July 1943. Her wreck was later salvaged and scrapped
in 1957.
Design and description
The submarines of the KD7 sub-class were medium-range attack submarines developed from the preceding KD6 sub-class. They displaced 1,862 metric tons (1,833 long tons) surfaced and 2,644 metric tons (2,602 long tons) submerged. The submarines were 105.5 meters (346 ft 2 in) long, had a beam of 8.25 meters (27 ft 1 in) and a draft of 4.6 meters (15 ft 1 in). The boats had a diving depth of 80 m (260 ft) and a complement of 86 officers and crewmen.[1]
For surface running, the boats were powered by two 4,000-
propeller shaft. When submerged each propeller was driven by a 900-horsepower (671 kW) electric motor. They could reach 23 knots (43 km/h; 26 mph) on the surface and 8 knots (15 km/h; 9.2 mph) underwater. On the surface, the KD7s had a range of 8,000 nautical miles (15,000 km; 9,200 mi) at 16 knots (30 km/h; 18 mph); submerged, they had a range of 50 nmi (93 km; 58 mi) at 5 knots (9.3 km/h; 5.8 mph).[2]
The boats were armed with six internal 53.3 cm (21.0 in)
anti-aircraft gun, but a 120 mm (4.7 in) deck gun for combat on the surface was substituted for one 25 mm mount during construction.[3]
Construction and career
Built by the
Navy List on 15 April 1944. Her wreck was salvaged from April 1956 to 1 March 1957 and scrapped at Kure.[4]
