Design and description
At the end of 1944, the Imperial Japanese Navy decided it needed large numbers of high-speed coastal submarines to defend the Japanese Home Islands[1] against an anticipated Allied invasion (named Operation Downfall by the Allies). To meet this requirement, the Ha-201-class submarines were designed as small, fast submarines[1] incorporating many of the same advanced ideas implemented in the German Type XXI and Type XXIII submarines. They were capable of submerged speeds of almost 14 knots (26 km/h; 16 mph).[1]
The Ha-201 class displaced 325 metric tons (320 long tons) surfaced and 447 metric tons (440 long tons) submerged.[1] The submarines were 53 meters (173 ft 11 in) long, had a beam of 4.00 meters (13 ft 1 in) and a draft of 3.44 meters (11 ft 3 in).[1] For surface running, the submarines were powered by a single 400-brake-horsepower (298 kW) diesel engine that drove one propeller shaft.[1] When submerged the propeller was driven by a 1,250-shaft-horsepower (932 kW) electric motor.[1] They could reach 11.8 knots (21.9 km/h; 13.6 mph) on the surface and 13.9 knots (25.7 km/h; 16.0 mph) submerged.[1] On the surface, the Ha-201-class submarines 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 105 nmi (194 km; 121 mi) at 2 knots (3.7 km/h; 2.3 mph).[1] Their armament consisted of two 533-millimeter (21 in) torpedo tubes with four torpedoes and a single mount for a 7.7-millimeter machine gun.[1]
Construction and commissioning
Ordered as Submarine No. 4920 and renamed Ha-210 and provisionally attached to the Sasebo Naval District on 5 May 1945,[2] Ha-210 was laid down on 14 May 1945 by the Sasebo Naval Arsenal at Sasebo, Japan.[2] She was launched on 10 June 1945[2] and was completed and commissioned on 11 August 1945.[2]
Service history
Upon commissioning, Ha-210 was attached formally to the Sasebo Naval District and assigned to Submarine Division 52.[2] On 15 August 1945 — four days after Ha-210 was commissioned — hostilities between Japan and the Allies ended.[2] She surrendered to the Allies at Sasebo on 2 September 1945.[2] On 2 November 1945, she was reassigned to Japanese Submarine Division Three under United States Navy command along with her sister ships Ha-201, Ha-202, Ha-203, and Ha-205.[2]
Disposal
The Japanese struck Ha-210 from the Navy list on 30 November 1945.[2] She was scuttled off Sasebo Bay along with the submarines Ro-31, Ha-207, Ha-215, Ha-216, Ha-217, Ha-219, and Ha-228 on 5 April 1946.[2]
