Hispanic Admirals in the United States Navy can trace their tradition of naval military service to the Hispanic sailors, who have served in the Navy during every war and conflict since the American Revolution.
 Prior to the Civil War, the highest rank reached by a Hispanic-American in the U.S. Navy was Commodore.
 Such was the case of Commodore Uriah Phillips Levy (1792–1862), a Sephardic Jew of Hispanic descent and great grandson of Dr. Samuel Nunez, who served in the War of 1812.
 During the American Civil War, the government of the United States recognized that the rapid expanding Navy was in need of admirals therefore, Congress proceeded to authorize the appointment of nine officers the rank of rear admiral.
 On July 16, 1862, Flag Officer David Glasgow Farragut became the first Hispanic-American to be appointed to the rank of rear admiral.
 Two years later (1864), Farragut became a vice admiral, and in 1866 the Navy's first full admiral.
 During World War I, Robert Lopez, the first Hispanic graduate of the United States Naval Academy, served with the rank of commodore in command of the Mare Island Naval Shipyard, and during World War II five Hispanics served with the ranks of rear admiral or above in either the European or Pacific Theater's of the war.
 As of April 2007, twenty-two Hispanic-Americans have reached the rank of admiral, and of this number thirteen were graduates of the USNA.
Trieste II (DSV-1) was the successor to "Trieste"—the United States Navy's first bathyscaphe purchased from its Swiss designers.
 The original "Trieste" design was heavily modified by the Naval Electronics Laboratory in San Diego, California and built at the Mare Island Naval Shipyard.
 "Trieste II" incorporated the original Terni, Italian-built sphere used in "Trieste", after it was made redundant by the new high-pressure sphere cast by the German Krupp Steelworks.
 The "Trieste" sphere was suspended from an entirely new float, more seaworthy and streamlined than the original but operating on identical principles.
 Completed in early 1964, "Trieste II" was placed on board USNS "Francis X. McGraw" (T-AK241) and shipped, via the Panama Canal, to Boston.
The Portsmouth Naval Shipyard Museum and the associated Lightship Museum are located on the downtown Portsmouth, Virginia, United States waterfront.
 The museum covers the 250+ year relationship with the shipyard - America's oldest and largest naval shipyard located on the Portsmouth Waterfront.
 The city and the shipyard have been intertwined since the founding of the Gosport Shipyard in 1767, which was later renamed Norfolk Navy Yard and finally Norfolk Naval Shipyard.
 This rich history is told through exhibits, hands-on programs and special events.
John Wills Greenslade (Bellevue, Ohio, January 11, 1880 – January 6, 1950) was a Vice Admiral in the United States Navy.
 Admiral Greenslade enjoyed a significant military career during World War II.
 From 1941-1944 Greenslade was Commandant, Twelfth Naval District, with additional duty as Commandant, Pacific Southern Naval Coastal Frontier.
 On January 8, 1942, while he was serving at Mare Island Naval Shipyard, Greenslade urged that American-born and alien Japanese be excluded from areas of strategic importance.
 On April 17, 1942, the Navy seized Treasure Island, San Francisco, California from the City of San Francisco under the direction of Vice Admiral Greenslade, and paid no compensation for the confiscated island.
 Admiral Greenslade claimed Treasure Island was required for "national security" and appropriated the island for the Navy.
The San Francisco Naval Shipyard was a United States Navy shipyard in San Francisco, located on 638 acre of waterfront at Hunters Point in the southeast corner of the city.
The San Francisco Bay Naval Shipyard was a short-lived shipyard formed in 1965 as the combination of the San Francisco Naval Shipyard (aka Hunters Point) and the Mare Island Naval Shipyard.
 The combined yards were the largest naval shipyard in the world, but the desired cost savings did not materialize, and the two yards reverted to separate existences in February 1970.
 The shipyard was used for radioactive testing when the United States was testing the atomic bomb.
 The site has since been contaminated.
 Now the Hunters Point Naval Shipyard is a Superfund site, as designated by the Environmental Protection Agency (EPA).
 It is the Navy's job to clean up the site to "reasonable" levels to those who live adjacent to the shipyard.
The Mare Island Naval Shipyard (MINSY) was the first United States Navy base established on the Pacific Ocean.
 It is located 25 miles northeast of San Francisco in Vallejo, California.
 The Napa River goes through the Mare Island Strait and separates the peninsula shipyard (Mare Island, California) from the main portion of the city of Vallejo.
 MINSY made a name for itself as the premier US West Coast submarine port as well as serving as the controlling force in San Francisco Bay Area shipbuilding efforts during World War II.
 The base closed in 1996 and has gone through several redevelopment phases.
 It was registered as a California Historical Landmark in 1960, and parts of it were declared a National Historic Landmark District in 1975.
The Portsmouth Naval Shipyard (PNS), often called the Portsmouth Navy Yard, is a United States Navy shipyard located in Kittery on the southern boundary of Maine near the city of Portsmouth, New Hampshire.
 PNS is tasked with the overhaul, repair, and modernization of US Navy submarines.
 The facility is sometimes confused with the Norfolk Naval Shipyard in Portsmouth, Virginia.
The Mare Island Strait is a channel at in the San Pablo Bay separating Mare Island and the mainland in Vallejo, California in Solano County.
 The strait was formerly used by the Mare Island Naval Shipyard until its closure in 1995.
 The strait is the mouth of the Napa River and is used for both recreational and freight boating.
 The Vallejo Ferry Terminal and its commuter ferry service to San Francisco are located on the strait.
Vice Admiral Alfred Eugene Montgomery (12 June 1891 – 15 December 1961) was an officer in the United States Navy who served in World War I and World War II.
 A graduate of the Naval Academy, he participated in operations on the Mexican Border.
 He trained for submarines, and became executive officer of the submarine USS "E-1" .
 In November 1914 he reported to the Mare Island Naval Shipyard where the new submarine USS "F-1" was being fitted out, and served as its commander from June 1917 until it was lost on 17 December 1917.
