Ro-19, originally named Submarine No. 36, was an Imperial Japanese Navy Kaichū-Type submarine of the Kaichū III subclass. She was commissioned in 1922 and operated in the waters of Japan. She was stricken in 1936.
Design and description
[edit]The submarines of the Kaichu III sub-class were a slightly improved version of the preceding Kaichu II subclass, the man difference being an increase in diving depth from 30 to 45.7 meters (98 to 150 ft).[1] They displaced 752 tonnes (740 long tons) surfaced and 1,013 tonnes (997 long tons) submerged. The submarines were 70.10 meters (230 ft 0 in) long and had a beam of 6.12 meters (20 ft 1 in) and a draft of 3.70 meters (12 ft 2 in).
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 Type 44 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
[edit]Ro-19 was laid down as Submarine No. 36 on 9 September 1920 by the Kure Naval Arsenal at Kure, Japan.[2] Launched on 28 December 1920,[2] she was completed and commissioned on 15 March 1922.[2]
Service history
[edit]Upon commissioning, Submarine No. 36 was assigned to Submarine Division 16 in Submarine Squadron 1 in the 1st Fleet.[2] Submarine Division 16 was reassigned to Submarine Squadron 2 in the 2nd Fleet on 1 December 1922,[2] and then to the Kure Naval District — in which it remained for the rest of the submarine's active career — on 1 December 1923.[2] In the years that followed, Submarine No. 36 was renamed Ro-19 on 1 November 1924,[2] and Submarine Division 16 served in the Kure Defense Division from 10 December 1928 to 15 November 1934.[2]
Ro-19 was stricken from the Navy list on 1 April 1936.[2] She was hulked, and on 1 April 1940 was renamed Haisen No. 5.[2] She was scrapped in 1948.[2]
