Ha-210 was an Imperial Japanese Navy Ha-201-class submarine. Completed and commissioned in August 1945 fours days before hostilities ended in World War II, she surrendered in September 1945 and was scuttled in April 1946.




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 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 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).
The Ha-201 class displaced 325 metric tons (320 long tons) surfaced and 447 metric tons (440 long tons) submerged. 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). For surface running, the submarines 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 1,250-shaft-horsepower (932 kW) electric motor. 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. 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). 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.




Construction and commissioning


Ordered as Submarine No. 4920 and renamed Ha-210 and provisionally attached to the Sasebo Naval District on 5 May 1945, Ha-210 was laid down on 14 May 1945 by the Sasebo Naval Arsenal at Sasebo, Japan. She was launched on 10 June 1945 and was completed and commissioned on 11 August 1945.




Service history


Upon commissioning, Ha-210 was attached formally to the Sasebo Naval District and assigned to Submarine Division 52. On 15 August 1945 — four days after Ha-210 was commissioned — hostilities between Japan and the Allies ended. She surrendered to the Allies at Sasebo on 2 September 1945. 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.




Disposal


The Japanese struck Ha-210 from the Navy list on 30 November 1945. 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.
