Naval Submarine Base New London is the primary United States Navy East Coast submarine base, also known as the "Home of the Submarine Force." It is located in Groton, Connecticut directly across the Thames River from its namesake city of New London. History In 1868, the State of Connecticut gave the Navy of land along the Thames River in Groton to build a Naval Station. Due to a lack of federal funding, it was not until 1872 that two brick buildings and a T-shaped pier were constructed and officially declared a Navy Yard. In 1898, Congress approved a coaling station to 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 Congressional appropriations were small and the Navy had little need for the yard, which was closed from 1898 to 1900 and its personnel reassigned. By 1912, oil replaced coal in warships and again the Yard was scheduled for closure and the land relinquished by the Navy. Submarine base established The Navy Yard was spared permanent closure in 1912 by an impassioned plea from Congressman Edwin W. Higgins of Norwich, who was worried about the loss of Federal spending in the region. On 13 October 1915, the monitor , a submarine tender, and four submarines arrived in Groton. Additional submarines and support craft arrived the following year, and the facility was named as the Navy's first submarine base. The first commander of the Yard was retired Commodore Timothy A. Hunt, who was recalled to service. He was living in New Haven, and he used the Central Hotel on State Street, New London when in town to attend to Yard duties on an "as needed" basis. The submarine base is physically located in the Town of Groton, but New London became associated with it because the base had its main offices and housing in New London. Following World War I, the Navy established schools and training facilities at the base. Wartime expansion The Base property expanded during the latter part of World War I. Congress approved over a million dollars for Base real estate and facilities expansion. By the end of the war, 81 buildings had been built to support 1,400 men and 20 submarines, although the land expansion was slowed through much of the 1920s. However, the Great Depression of the
