Navy Region Southwest 
Arizona, California, Colorado, Nevada, New Mexico, Utah

Commander Navy Southwest formerly known as Naval Base San Diego, and the Eleventh Naval District, was established in 1919. Headquarters for the first Commander, with a staff of seven officers, was located at Naval Station North Island. In 1922, when Naval Supply Center buildings at the foot of Broadway Street on Harbor Drive were completed, the Naval Base Headquarters moved to its present site.

With the outbreak of World War II, San Diego's naval establishment played an important role in coordinating the supply provisioning to the war fronts in the Pacific. Naval bases and stations throughout the region were expanded to provide maximum support to combatant forces of the fleet. With Korea, Vietnam and "cold war" commitments, fleet support activities under Commander Naval Base San Diego remained at a very high level.

In 1998, the Navy embarked on a new era in shore management, with San Diego leading the way. As the Navy reduced its operational forces, it became essential for the shore establishment supporting those forces to be realigned. In 1999 the command was officially renamed Commander Navy Region Southwest. As the Naval shore installation management headquarters for the Southwest region (California, Arizona and Nevada), Navy Region Southwest provides coordination of base operating support functions for operating forces throughout the region. This includes providing expertise in areas such as housing, environmental, security, family services, port services, air services, bachelor quarters, supply, medical and logistical concerns for the hundreds of thousands of active duty, reserve and retired military members in the area. The command also serves as the regional coordinator for the Commander, U. S. Pacific Fleet, headquartered in Hawaii, coordinating support for bases in Southern California and Nevada.

The bases that fall under this new region are: Naval Station San Diego; Naval Base Point Loma (former SUBASE San Diego); Naval Air Station North Island; Naval Amphibious Base Coronado; Naval Air Facility El Centro, CA; Naval Air Station Lemoore, CA; Naval Base Ventura County (former Naval Construction Battalion Center Port Hueneme & Naval Air Station Point Mugu); Naval Weapons Station Seal Beach, CA; Naval Weapons Station, Fallbrook, CA; Naval Weapons Station, Concord, CA; and Naval Air Station, Fallon, NV.

The Commander also serves as regional environmental coordinator for California, Arizona and Nevada and coordinates and oversees environmental compliance actions with local, state and federal regulatory agencies. Additionally, COMNAVREGSW is responsible for planning and coordinating Department of the Navy response to civil emergencies within the states of Nevada, Utah, Colorado, Arizona and California.
