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]
Ro-16 was laid down as Submarine No. 37 on 18 November 1920 by the Kure Naval Arsenal at Kure, Japan.[2] Launched on 22 April 1921,[2] she was completed and commissioned on 29 April 1922.[2]
Upon commissioning, Submarine No. 37 was attached to the Kure Naval District, to which she remained attached throughout her career.[2] She was assigned to Submarine Division 15 — in which she spent the rest of her career — on 15 May 1922.[2] Submarine Division 15 served in the Kure Defense Division from 1 December 1922 to 1 December 1923.[2] Submarine No. 37 was renamed Ro-16 on 1 November 1924,[2] and on 1 December 1926 Submarine Division 15 began another assignment to the Kure Defense Division that lasted through the end of Ro-16′s active service.[2]
Ro-16 was stricken from the Navy list on 1 September 1933.[2] In 1934, her hulk was transferred to the Ehime Prefectural Yuge Commercial Ship School, later renamed the Yuge National College of Maritime Technology, at Yuge, Ehime, Japan.
