Ro-13, originally named Submarine No. 23, was an Imperial Japanese Navy Kaichū-Type submarine of the Kaichū II subclass. She was commissioned in 1920 and operated in the waters of Japan. She was stricken in 1932.
Design and description[]
The submarines of the Kaichu II sub-class were larger and had a greater range than the preceding Kaichu I subclass, but they had the same powerplant, so their greater size resulted in a loss of some speed.[1] They also had a modified conning tower, bow, and stern, and the stern was overhanging.[1] They displaced 752 tonnes (740 long tons) surfaced and 1,019 tonnes (1,003.1 long tons) submerged. The submarines were 70.10 meters (230 ft 0 in) long and had a beam of 6.10 meters (20 ft 0 in) and a draft of 3.68 meters (12 ft 1 in). They had a diving depth of 30 meters (98 ft).
For surface running, the submarines were powered by two 1,450-brake-horsepower (1,081 kW) Sulzer Mark II diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a 600-horsepower (447 kW) electric motor. They could reach 16.5 knots (31 km/h; 19 mph) on the surface and 8.5 knots (15.7 km/h; 9.8 mph) underwater. On the surface, they had a range of 6,000 nautical miles (11,000 km; 6,900 mi) at 10 knots (19 km/h; 12 mph); submerged, they had a range of 85 nmi (157 km; 98 mi) at 4 knots (7.4 km/h; 4.6 mph).
The submarines were armed with six 450 mm (18 in) torpedo tubes, four internal tubes in the bow and two external tubes mounted on the upper deck, and carried a total of ten torpedoes. They were also armed with a single 76.2 mm (3.00 in) deck gun mounted aft of the conning tower.[1]
Construction and commissioning[]
Ro-13 was laid down as Submarine No. 23 on 14 September 1918 by the Kure Naval Arsenal at Kure, Japan.[2] Launched on 26 August 1919,[2] she was completed and commissioned on 30 September 1920.[2]
Service history[]
Upon commissioning, Submarine No. 23 was attached to the Kure Naval District and was assigned to the .[2] On 1 December 1920 she was reassigned to Submarine Division 14 in Submarine Squadron 1 in the 1st Fleet.[2] Submarine Division 14 was assigned to the Kure Defense Division and Kure Naval District on 1 July 1921, then to Submarine Squadron 2 in the 2nd Fleet on 1 December 1922.[2]
On 1 December 1923, Submarine No. 23 was transferred to Submarine Division 3, assigned to duty in the , and attached to the Yokosuka Naval District, and she remained in all three of those assignments for the remainder of her active career.[2] She was renamed Ro-13 on 1 November 1924.[2]
Ro-13 was stricken from the Navy list on 1 April 1932.[2] She was renamed Haisen No. 2 that day.[2]
