Two submarines of the United States Navy have been named USS Sealion for the sea lion, any of several large, eared seals native to the Pacific.
The United States Navy (USN) is the naval warfare service branch of the United States Armed Forces and one of the seven uniformed services of the United States. It is the largest and most capable navy in the world and it has been estimated that in terms of tonnage of its active battle fleet alone, it is larger than the next 13 navies combined, which includes 11 U.S. allies or partner nations. with the highest combined battle fleet tonnage and the world's largest aircraft carrier fleet, with eleven in service, and two new carriers under construction. With 319,421 personnel on active duty and 99,616 in the Ready Reserve, the Navy is the third largest of the service branches. It has 282 deployable combat vessels and more than 3,700 operational aircraft as of March 2018, making it the second-largest air force in the world, after the United States Air Force.
Sea lions are sea mammals characterized by external ear flaps, long foreflippers, the ability to walk on all fours, short, thick hair, and a big chest and belly. Together with the fur seals, they comprise the family Otariidae, eared seals, which contains six extant and one extinct species in five genera. Their range extends from the subarctic to tropical waters of the global ocean in both the Northern and Southern Hemispheres, with the notable exception of the northern Atlantic Ocean. They have an average lifespan of 20–30 years. A male California sea lion weighs on average about 300 kg (660 lb) and is about 8 ft (2.4 m) long, while the female sea lion weighs 100 kg (220 lb) and is 6 ft (1.8 m) long. The largest sea lion is Steller's sea lion, which can weigh 1,000 kg (2,200 lb) and grow to a length of 10 ft (3.0 m). Sea lions consume large quantities of food at a time and are known to eat about 5–8% of their body weight at a single feeding. Sea lions can go around 16 knots in water and at their fastest they can go up to 30 knots. Three species, the Australian sea lion, the Galápagos sea lion and the New Zealand sea lion are listed as Endangered.
Pinnipeds, commonly known as seals, are a widely distributed and diverse clade of carnivorous, fin-footed, semiaquatic marine mammals. They comprise the extant families Odobenidae, Otariidae, and Phocidae. There are 33 extant species of pinnipeds, and more than 50 extinct species have been described from fossils. While seals were historically thought to have descended from two ancestral lines, molecular evidence supports them as a monophyletic lineage. Pinnipeds belong to the order Carnivora and their closest living relatives are believed to be bears and the superfamily of musteloids, having diverged about 50 million years ago.
USS Sealion (SS-195), a Sargo-class submarine, was the first ship of the United States Navy to be named for the sea lion, any of several large, eared seals native to the Pacific.
The Sargo-class submarines were among the first US submarines to be sent into action after the Japanese attack on Pearl Harbor, starting war patrols the day after the attack, having been deployed to the Philippines in late 1941. Similar to the previous Salmon class, they were built between 1937 and 1939. With a top speed of 21 knots, a range of 11,000 nautical miles (20,000 km), and a reliable propulsion plant, along with the Salmons they were an important step in the development of a true fleet submarine. In some references, the Salmons and Sargos are called the "New S Class", 1st and 2nd Groups.
World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945. The vast majority of the world's countries—including all the great powers—eventually formed two opposing military alliances: the Allies and the Axis. A state of total war emerged, directly involving more than 100 million people from over 30 countries. The major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. World War II was the deadliest conflict in human history, marked by 50 to 85 million fatalities, most of whom were civilians in the Soviet Union and China. It included massacres, the genocide of the Holocaust, strategic bombing, premeditated death from starvation and disease, and the only use of nuclear weapons in war.

Newport News Shipbuilding (NNS), a division of Huntington Ingalls Industries, is the largest industrial employer in Virginia, and sole designer, builder and refueler of United States Navy aircraft carriers and one of two providers of U.S. Navy submarines. Founded as the Chesapeake Dry Dock and Construction Co. in 1886, Newport News Shipbuilding has built more than 800 ships, including both naval and commercial ships. Located in the city of Newport News, their facilities span more than 550 acres (2.2 km2), strategically positioned in one of the great harbors of the East Coast.
Three submarines of the United States Navy have borne the name USS Skate, named for a type of ray.
Two submarines of the United States Navy have been named USS Tang, after the tang, or surgeonfish, especially of the several West Indian species.
USS Pampanito (SS-383/AGSS-383), a Balao-class submarine, was a United States Navy ship, the third one named for the pompano fish. She completed six war patrols from 1944 to 1945 and served as a Naval Reserve Training ship from 1960 to 1971. She is now a National Historic Landmark, preserved as a memorial and museum ship in the San Francisco Maritime National Park Association located at Fisherman's Wharf.
USS Herring (SS-233), a Gato-class submarine, was the only ship of the United States Navy to be named for the herring.
The Balao class was a successful design of United States Navy submarine used during World War II, and with 120 units completed, the largest class of submarines in the United States Navy. An improvement on the earlier Gato class, the boats had slight internal differences. The most significant improvement was the use of thicker, higher yield strength steel in the pressure hull skins and frames, which increased their test depth to 400 feet (120 m). Tang actually achieved a depth of 612 ft (187 m) during a test dive, and exceeded that test depth when taking on water in the forward torpedo room while evading a destroyer.
The New York Shipbuilding Corporation was an American shipbuilding company that operated from 1899 to 1968, ultimately completing more than 500 vessels for the U.S. Navy, the United States Merchant Marine, the United States Coast Guard, and other maritime concerns. At its peak during World War II, NYSB was the largest and most productive shipyard in the world. Its best-known vessels include the destroyer USS Reuben James (DD-245), the cruiser USS Indianapolis (CA-35), the aircraft carrier USS Kitty Hawk (CV-63), the nuclear-powered cargo ship NS Savannah, and a quartet of cargo-passenger liners nicknamed the Four Aces.
USS Lionfish (SS-298), a Balao-class submarine, was the only ship of the United States Navy named for the lionfish, a scorpaenid fish native to the Pacific and an invasive species found around the Caribbean. She was designated a National Historic Landmark in 1986, and is now on display at Battleship Cove in Fall River, Massachusetts.
The United States' S-class submarines, often simply called S-boats, were the first class of submarines with a significant number built to United States Navy designs. Others of this class were built to contractor designs.
Manitowoc Shipbuilding Company, located in Manitowoc, Wisconsin, was a major shipbuilder for the Great Lakes. It was founded in 1902, and made mainly steel ferries and ore haulers. During World War II, it built submarines, tank landing craft (LCTs), and self-propelled fuel barges called "YOs". Employment peaked during the military years at 7000. The shipyard closed in 1968, when Manitowoc Company bought Bay Shipbuilding Company and moved their shipbuilding operation to Sturgeon Bay.

Battleship Memorial Park is a military history park and museum located on the western shore of Mobile Bay in Mobile, Alabama. It has a collection of notable aircraft and museum ships including the South Dakota-class battleship USS Alabama and Gato-class submarine USS Drum. USS Alabama and USS Drum are both National Historic Landmarks; the park as a whole was listed on the Alabama Register of Landmarks and Heritage prior to that time, on October 28, 1977.
Seawolf Park is a memorial to USS Seawolf (SS-197), a United States Navy Sargo-class submarine mistakenly sunk by U.S. Navy forces in 1944 during World War II. It is located on Pelican Island, just north of Galveston, Texas, in the United States.
The 4"/50 caliber gun was the standard low-angle, quick-firing gun for United States, first appearing on the monitor Arkansas and then used on "Flush Deck" destroyers through World War I and the 1920s. It was also the standard deck gun on S-class submarines, and was used to rearm numerous submarines built with 3-inch (76 mm) guns early in World War II. United States naval gun terminology indicates the gun fired a projectile 4-inch (102 mm) in diameter, and the barrel was 50 calibers long.
