USS H-9 (SS-152) 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.

Design

The H-class submarines had an overall length of 150 ft 4 in (45.8 m), a beam of 15 ft 10 in (4.8 m), and a mean draft of 12 ft 5 in (3.8 m). They displaced 358 long tons (364 t) on the surface and 467 long tons (474 t) submerged. They had a diving depth of 200 ft (61.0 m). The boats had a crew of 2 officers and 23 enlisted men. ^[3]

For surface running, they were powered by two New London Ship & Engine Company 475- brake-horsepower (354 kW) diesel engines, each driving one propeller shaft. When submerged each propeller was driven by two 170-horsepower (127 kW) Electro-Dynamic Company electric motors. They could reach 14  kn (26 km/h; 16 mph) on the surface and 10.5 kn (19.4 km/h; 12.1 mph) underwater. ^[3] On the surface, the boats had a range of 2,300  nmi (4,300 km; 2,600 mi) at 11 kn (20 km/h; 13 mph) and 100 nmi (190 km; 120 mi) at 5 kn (9.3 km/h; 5.8 mph) submerged. ^[4]

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. ^[4]

Construction

H-9 was laid down on 1 June 1918, at the Puget Sound Navy Yard, she had been already been preassembled by the British Pacific Construction and Engineering Company, in Vancouver, Canada, for Imperial Russian Government, which had failed to exist in September 1917. She was launched on 23 November 1918, and commissioned on 25 November 1918. ^[2]

Service history

USS H-9 submerging, c. 1922

Joining Submarine Division 6 (SubDiv 6) at San Pedro, California, and later being transferred to SubDiv 7 (SubDiv 7) there, H-9 participated in a variety of battle and training exercises along the West Coast. She also patrolled off Santa Catalina Island, and put in at Mare Island Navy Yard for periodic overhauls. ^[5]

Fate

H-9 sailed from San Pedro, on 25 July 1922, and arrived in Norfolk, Virginia on 14 September, with SubDivs 6 and 7. The submarine decommissioned at Norfolk, Virginia, on 3 November. Her name was struck from the Naval Vessel Register on 26 February 1931. She was sold for scrapping on 28 November 1933. ^[5]
