Today, the Naval Submarine Base New London occupies more than 680 acres, with more than 160 major facilities and 15 nuclear submarines. Technological changes contributed to a cycle of renewal and reconstruction of the various physical facilities that supported both submarine operations as well as the Submarine School. Retired from service in 1980, Nautilus became an historic exhibit at the Submarine Force Museum, adjacent to the base, in 1985. Commissioned in 1954, and home-ported at New London, Nautilus became the first vessel to transit the North Pole during an historic trip across the Arctic in 1958. The arrival of USS Nautilus (SSN-571), the world’s first nuclear-powered vessel, created changes at the base. The capabilities of the remainder were upgraded and these boats were to serve until the early 1970s. Most of the wartime fleet was sold for scrap metal during the early 1960s. Immediately after the war, the Submarine Force was significantly reduced. The second largest expansion of Submarine Base New London occurred during World War II when it grew from 112 acres to 497 acres. Generations of submariners practiced escaping from sunken submarines through the Dive Tower by ascending in a 100-foot column of water. The Submarine Escape Training Tank, long known as the “Dive Tower,” was a constructed during this period and became a prominent feature to the local landscape from 1930 to 1992. Over 26 high-quality warehouses, barracks, and workshops were built at the base under these programs. Roosevelt created a series of federal government employment programs that contributed significantly to the Submarine Base. However, during the Great Depression era, President Franklin D. The expansion of the base was slowed through much of the 1920s. By the end of the war, 81 buildings had been built to support 1,400 men and 20 submarines. The base property expanded during the latter part of World War I. On June 21, 1916, the mission of the yard was changed forever when Commander Yeates Stirling assumed command of the newly designated Submarine Base, the New London Submarine Flotilla, and the Submarine School. However, the 18 October 1915 arrival of the submarines G-1, G-2, and G-4 under the care of the tender USS Ozark (BM-7), and submarines E-1, D-1, and D-3 with the tender USS Tonopah (BM-8) gave new purpose to the yard’s existence. By 1912, oil had replaced coal in warships and the yard was repeatedly scheduled for closure. In 1898, Congress approved a coaling station be built at the yard for refueling small naval ships traveling through the waters of New England. The navy yard was first used for laying up inactive ships. The base’s beginnings were as a naval yard and storage depot. "We don't want that happening, so we teach the students to never ever hold their breath.Naval Submarine Base New London is the Navy's first submarine base and the "Home of the Submarine Force." ![]() ![]() "Our biggest concern here is POIS, or pulmonary overinflation syndrome, that involves having gas-filled spaces in your body expanding to the point where they rupture," said Petty Officer 2nd Class Frank Phelan, a Navy diver and high-risk training instructor. Students then learn about the physiological challenges of making a pressurized escape before moving to more rigorous training in the water. Pressure builds within the chamber until it’s equal to water pressure at "escape depth." If the student is unable to perform the Valsalva maneuver, the test stops and pressure is slowly released so he or she can exit. Though the dive chamber is at sea level, inside, the students feel like they are 60 feet below the surface. Candidates who have successfully performed the Valsalva maneuver will then be subject to increased pressure in a dive recompression chamber with a dive medical technician. ![]()
