The history of Point Loma Naval Base begins in 1795. The Spanish began building a fort at the base of Point Guijarros, opposite the tip of North Island. This fort was built on the land which is today known as Ballast Point. Fort Guijarros was later finished in 1798 and then abandoned by the Spanish in 1845. In 1846 United States Capt. Samuel Du Pont, entered the abandoned land where the fort once stood and raised the American flag. Shortly after in 1848 the Treaty of Guadalupe Hidalgo ended the Mexican–American War and the Americans claimed Point Loma. In February 1852 President Millard Fillmoreset aside the southern portion of Point Loma of about for military purposes. Subsequently, it was assigned to the U.S. Army and named '', after General William Rosecrans, an 1842 graduate of the U.S. Military Academy. In 1898 the Army built a coast artillery installation on the site which remained active until 1945, when the University of California Division of War Research and the Navy Radio and Sound Laboratory occupied the site as the Navy Electronics Laboratory. NEL was renamed the Naval Ocean Systems Center in 1977 and incorporated into the Space and Naval Warfare Systems Command in 1997. In 1932, the site of Fort Rosecrans was registered as California Historical Landmark #62. From February 1940 through October 1944 Fort Rosecrans was garrisoned by the 19th Coast Artillery Regiment. Submarine Group, San Diego was established in 1946, and Submarine Flotilla 1 was activated in 1949. In 1959 Fort Rosecrans was turned over to the U.S. Navy. The Navy Submarine Support Facility was established in November 1963 on of the land. Bathyscaphe Trieste arrived at NEL in 1958; and modified Bathyscaphe Trieste II was based here from 1965 to 1984. On 27 November 1974 the base was re-designated a shore command, serving assigned submarines, Submarine Group Five, Submarine Squadron Three, Submarine Development Group One, the Submarine Training Facility and later, Submarine Squadron Eleven. On 1 October 1981 the base was designated as Naval Submarine Base San Diego. Starting in April 1995, several commands were decommissioned or their homeports were changed to meet the post-Cold War down-sizing requirements of the Navy. Commands throughout San Diego were regionalized in an effort to provide equal or better base services while managing a reduced budget. The six naval installations on Point Loma were consolidated as Naval Base Point Loma on 1 October 1998.
