USS N-7 (SS-59)

USS N-7 (SS-59) was an N-class coastal defense submarine of the United States Navy. Her keel was laid down on 20 April 1915 by Lake Torpedo Boat Company in Bridgeport, Connecticut. N-boats built by Lake had slightly different specifications from the ones built by Seattle Construction and Drydock and are sometimes considered a separate class.

She was launched on 19 May 1917, sponsored by Mrs Frank Miller, and commissioned on 15 June 1918, with Lieutenant Walter S. Kass in command.

Service history
After outfitting at New London, Connecticut, she patrolled the New England coast, to guard against attacks by German U-boats, until 17 September, when she put into New York City for upkeep. Returning to New London on 24 October, she remained there until 21 June 1919, when she sailed to Philadelphia, Pennsylvania, for extensive overhaul. She returned to New London on 31 March 1920 and remained there until placed in reserve on 7 June.

She spent 1921 in reserve at New London, except for short cruises to Boston, Massachusetts, and Newport, Rhode Island. Later that year, her engines were transferred to a more modern L-class submarine. Towed by tug USS Lykens (AT-56), she departed on 26 January 1922 for Philadelphia, where she decommissioned on 7 February. Her hulk was sold to Joseph G. Hitner of Philadelphia for scrap on 5 June.
