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-brake-horsepower (298 kW) diesel engine that drove one propeller shaft. When submerged the propeller was driven by a 140-horsepower (104 kW) electric motor. They could reach 10 knots (19 km/h; 12 mph) on the surface and 5 knots (9.3 km/h; 5.8 mph) underwater.[2] On the surface, the Ha-101s had a range of 3,000 nautical miles (5,600 km; 3,500 mi) at 10 knots (19 km/h; 12 mph); submerged, they had a range of 46 nmi (85 km; 53 mi) at 2.3 knots (4.3 km/h; 2.6 mph). The boats were armed a single mount for a 25 mm (1 in) Type 96anti-aircraft gun.[3]
Construction and commissioning
Ha-111 was laid down on 6 November 1944 by Mitsubishi at Kobe, Japan, as Small Supply Submarine No. 4611.[4] Renamed Ha-111, she was launched in 1945.[4] During construction, she underwent conversion to a submarine tender for midget submarines, the conversion involving modifying her cargo hold to accommodate ten 450-millimeter (17.7 in) torpedoes for midget submarines.[4] She was completed and commissioned on 13 July 1945.[4]
Service history
Upon commissioning, Ha-111 was assigned to the 10th Special Attack Unit.[4] Hostilities between Japan and the Allies ended on 15 August 1945.[4] and she surrendered to the Allies at Saeki on 2 September 1945.[4]
