USS H-7 (SS-150)

USS "H-7" (SS-150) was an H class submarine that served in active duty with the U.S. Navy from 1918 to 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-7" (SS-150) was launched on 17 October 1918 and commissioned on 24 October with Lieutenant Edmund A. Crenshaw in command.

The submarine, attached to SubDiv 6 and later to SubDiv 7, operated out of San Pedro, California, on various battle and training exercises with the other ships of her division. She also patrolled out of San Pedro with interruptions for overhaul at Mare Island.

"H-7" reached Norfolk on 14 September 1922, having sailed from San Pedro on 25 July, and decommissioned there on 23 October 1922. Her name was struck from the Naval Vessel Register on 26 February 1931. She was sold for scrapping 28 November 1933.
