USS H-9 (SS-152)

USS H-9 (SS-152) was an H-class submarine that was on active duty with the United States Navy from 1918-1922.

The Imperial Russian Navy ordered 18 H-class submarines from the Electric Boat Company in 1915. Eleven were delivered, and served as the American Holland class submarines, but shipment of the final six was held up pending the outcome of the Russian Revolution of 1917, and the boats were stored in knockdown condition at Vancouver, British Columbia. All six were purchased by the United States Navy on 20 May 1918 and assembled at Puget Sound Navy Yard.

H-9 was launched on 23 November 1918 and commissioned on 25 November with Lieutenant Clarke Withers in command.

Joining Submarine Division 6 (SubDiv 6) at San Pedro, California, and later being transferred to 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 for periodic overhauls.

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 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.
