USS H-6 (SS-149) was a H-class submarine originally built for the Imperial Russian Navy. Six of these were not delivered pending the outcome of the Russian Revolution of 1917 before being purchased by the United States Navy on 20 May 1918.

Description

The H-class submarines had a length of 150 feet 4 inches (45.8 m) overall, a beam of 15 feet 10 inches (4.8 m) and a mean draft of 12 feet 5 inches (3.8 m). They displaced 358 long tons (364 t) on the surface and 467 long tons (474 t) submerged. The boats had a crew of 2 officers and 23 enlisted men. They had a diving depth of 200 feet (61.0 m).[1]

For surface running, they were powered by two New London Ship & Engine Co. 475-brake-horsepower (354 kW) diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a 170-horsepower (127 kW) Electro Dynamic Co. electric motor. They could reach 14 knots (26 km/h; 16 mph) on the surface and 10.5 knots (19.4 km/h; 12.1 mph) underwater.[1] On the surface, the boats had a range of 2,300 nautical miles (4,300 km; 2,600 mi) at 11 knots (20 km/h; 13 mph) and 100 nmi (190 km; 120 mi) at 5 knots (9.3 km/h; 5.8 mph) submerged.[2]

The boats were armed with four 18-inch (450 mm) torpedo tubes in the bow. They carried four reloads, for a total of eight torpedoes.[2]

Construction and career

H-6 was launched on 26 August 1918, and commissioned on 9 September. As part of Submarine Division 6 (SubDiv 6) and later SubDiv 7, H-6 was based at San Pedro, California. From there, she operated along the West Coast, participating in various battle and training exercises with her sister submarines. Occasional patrol duty off Santa Catalina Island and overhauls at Mare Island varied this training routine.

Departing San Pedro on 25 July 1922 with SubDivs 6 and 7, H-6 reached Norfolk, Virginia on 14 September. She decommissioned there on 23 October. H-6 was struck from the Naval Vessel Register on 26 February 1931. She was sold for scrapping on 28 November 1933.
