USS R-18 (SS-95) was an R-class coastal and harbor defense submarine of the United States Navy. Her keel was laid down on 16 June 1917 by the Union Iron Works in San Francisco, California. She was launched on 8 January 1918 sponsored by Miss Marion S. Russell, and commissioned on 11 September 1918 with Lieutenant Commander Felix X. Gygax in command.
Following shakedown, R-18 was assigned, briefly, to the Panama Canal Zone. At the end of the year, 1918, she returned to California. At San Pedro, California, from January to March 1919, she then underwent overhaul at San Francisco, California, and on 17 June got underway for Hawaii. On 25 June she arrived at Pearl Harbor. Based there for over a decade, she served with the fleet, training personnel and testing new submarine equipment. In July 1920 she was given hull classification symbol SS-95.
R-18 departed Hawaii 12 December 1930, transited the Panama Canal, thence continued on the East Coast for inactivation. Arriving at Philadelphia, Pennsylvania, on 9 February 1931, she was decommissioned 13 May and berthed at League Island until after the outbreak of World War II.
Recommissioned 8 January 1941, R-18 was at New London, Connecticut, for reconditioning and fitting out into May. On 12 May she got underway for the Canal Zone where she patrolled into September. In October, she returned to New London, whence after overhaul, she conducted training exercises in submarine and anti-submarine warfare. In early January 1942, she shifted her training activities to the Casco Bay, Maine, area. Then, later in the month, she added patrols along a line between Nantucket Light and Bermuda to her schedule.
