USS Sailfish (SS-192), was a US Sargo-class submarine, originally named Squalus. As the Squalus, the submarine sank off the coast of New Hampshire during test dives on 23 May 1939. The sinking drowned 26 crew members, but an ensuing rescue operation, using the McCann Rescue Chamber for the first time, saved the lives of the remaining 33 aboard. The submarine was salvaged in late 1939 and decommissioned.
The submarine was recommissioned as the Sailfish in May 1940, and conducted numerous patrols in the Pacific War during World War II, earning nine battle stars. She was decommissioned in October 1945 and later scrapped; the conning tower remains on display at Portsmouth Naval Shipyard in Kittery, Maine.
The United States Navy (USN) is the maritime service branch of the United States Armed Forces and one of the eight uniformed services of the United States. It is the largest and most powerful navy in the world, with the estimated tonnage of its active battle fleet alone exceeding the next 13 navies combined, including 11 U.S. allies or partner nations as of 2015. It has the highest combined battle fleet tonnage (4,635,628 tonnes as of 2019) and the world's largest aircraft carrier fleet, with eleven in service, two new carriers under construction, and five other carriers planned. With 336,978 personnel on active duty and 101,583 in the Ready Reserve, the U.S. Navy is the third largest of the U.S. military service branches in terms of personnel. It has 290 deployable combat vessels and more than 2,623 operational aircraft as of June 2019.The U.S. Navy traces its origins to the Continental Navy, which was established during the American Revolutionary War and was effectively disbanded as a separate entity shortly thereafter. After suffering significant loss of goods and personnel at the hands of the Barbary pirates from Algiers, the U.S. Congress passed the Naval Act of 1794 for the construction of six heavy frigates, the first ships of the U.S. Navy. The U.S. Navy played a major role in the American Civil War by blockading the Confederacy and seizing control of its rivers. It played the central role in the World War II defeat of Imperial Japan. The U.S. Navy emerged from World War II as the most powerful navy in the world. The 21st century U.S. Navy maintains a sizable global presence, deploying in strength in such areas as the Western Pacific, the Mediterranean, and the Indian Ocean. It is a blue-water navy with the ability to project force onto the littoral regions of the world, engage in forward deployments during peacetime and rapidly respond to regional crises, making it a frequent actor in U.S. foreign and military policy.
The U.S. Navy is part of the Department of the Navy, alongside the U.S. Marine Corps, which is its coequal sister service. The Department of the Navy is headed by the civilian Secretary of the Navy. The Department of the Navy is itself a military department of the Department of Defense, which is headed by the Secretary of Defense. The Chief of Naval Operations (CNO) is the most senior Navy officer serving in the Department of the Navy.
