АҚШ H классы суалты қайығы (USS H-6)

H class submarine of the United States

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.

The H class submarines had a length of 150 feet (46 m) overall, a beam of 15 feet (5 m) and a mean draft of 12 feet (4 m). They displaced on the surface and submerged. The boats had a crew of 2 officers and 23 enlisted men. They had a diving depth of 200 feet (61 m). For surface running, they were powered by two New London Ship & Engine Co. diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a Electro Dynamic Co. electric motor. They could reach on the surface and underwater. 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.

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.
