Ha-210 was anImperial Japanese NavyHa-201-classsubmarine. Completed and commissioned in August 1945 four days before hostilities ended inWorld War II, she surrendered in September 1945 and wasscuttled in April 1946.
At the end of 1944, the Imperial Japanese Navy decided it needed large numbers of high-speed coastal submarines to defend theJapanese Home Islands[1] against an anticipatedAllied invasion (namedOperation Downfall by the Allies). To meet this requirement, theHa-201-class submarines were designed as small, fast submarines[1] incorporating many of the same advanced ideas implemented in the GermanType XXI andType XXIII submarines. They were capable of submerged speeds of almost 14 knots (26 km/h; 16 mph).[1]
TheHa-201 classdisplaced 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 abeam of 4.00 meters (13 ft 1 in) and adraft 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 onepropeller shaft.[1] When submerged the propeller was driven by a 1,250-shaft-horsepower (932 kW)electric motor.[1] They could reach 11.8knots (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, theHa-201-class submarines had a range of 3,000nautical 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 fourtorpedoes and a single mount for a 7.7-millimetermachine gun.[1]
Ordered asSubmarine No. 4920 and renamedHa-210 and provisionally attached to theSasebo Naval District on 5 May 1945,[2]Ha-210 waslaid down on 14 May 1945 by theSasebo Naval Arsenal atSasebo,Japan.[2] She waslaunched on 10 June 1945[2] and was completed andcommissioned on 11 August 1945.[2]
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 afterHa-210 was commissioned — hostilities between Japan and theAllies 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 underUnited States Navy command along with hersister shipsHa-201,Ha-202,Ha-203, andHa-205.[2]
The Japanese struckHa-210 from the Navy list on 30 November 1945.[2] She wasscuttled offSasebo Bay along with the submarinesRo-31,Ha-207,Ha-215,Ha-216,Ha-217,Ha-219, andHa-228 on 5 April 1946.[2]
