Today, submarines are an important part of the U.S. Navy. Changes in world politics and further adaptations of sea, land, and space technologies are creating new challenges for submarines in the 21st century. In the future, some submarines may contain no crew at all, but merely computer technology that talks to satellites and transfers information to distant military bases for analysis.
The first American submarine was designed before the Revolutionary War by David Bushnell. He designed and built a one-man submersible vessel that he called “Turtle”. Bushnell’s Turtle featured a hand-cranked screw-like oar that moved the boat forward and back underwater, air pipes that brought fresh air into the boat, ballast tanks that took on water to dive and emptied to ascend, and a primitive torpedo to attack enemy ships. Between the American Revolution and the Civil War many individuals experimented with submarine technology, including American Robert Fulton, an innovator and promoter of the steam engine. In 1800, Fulton completed his version of a submarine, “Nautilus”. Fulton’s design introduced elements that may be found in modern submarines, such as adjustable diving planes for easy vertical maneuvering underwater, a dual system of propulsion, and a compressed air system that allowed the crew about four hours of underwater travel.
After the Civil War the U.S. Navy recognized the potential for submarines in its fleet and held a design competition for a new underwater vessel. John Holland, a submarine designer won the competition and began building the submarine “Pluger” and later an improved version the “Holland VI”. Holland intruduced a new method of propulsion using a gasoline engine. Holland designed a gasoline engine that turned a propeller while the boat cruised on the surface. The engine ran a generator, a machine that produces electricity, to charge batteries necessary to run an electric motor during underwater operations. The vessel proved succesful and was added to the fleet as USS Holland (SS-1). After 1909, The gasoline-powered engines were replaced by diesel powered-engines.
Despite the success of diesel-powered submarines, the quest for a single power source continued. The concept of nuclear power was discovered by German scientists in the 1930’s. U.S. Navy Admiral Hyman G. Rickover.Rickover managed a research team that converted the concepts of nuclear power into working submarines. Those small nuclear power plants on submarines could supply the necessary power for these boats to travel up to 500,000 miles and to stay underwater almost indefinitely without refueling. On January 17, 1955, the first nuclear-powered submarine, USS Nautilus (SSN-571) went to sea. On her first voyage, Nautilus traveled completely submerged in the Atlantic for more than 1,300 miles. In 1958, she traveled under the polar ice cap and reached the North Pole.
List of U.S. Navy submarines by class
Submarines of the United States Navy are built in classes, using a single design for a number of boats. Minor variations occur as improvements are incorporated into the design, so later boats of a class may be more capable than earlier. Also, boats are modified, sometimes extensively, while in service, creating departures from the class standard. However, in general, all boats of a class are noticeably similar.
Pre World-War I
Class | No. build | Commisioned | Notes |
Alligator | 1 | 1862 | First submarine in the U.S. Navy. Purpose was to protect wooden ships against ironclads. |
Holland | 1 | 1900 | 5 others were made; only Holland (SS-1) entered the U.S. Navy as it was the first officially commissioned submarine purchased on 11-04-1900. |
Plunger | 7 | 1903 | Later renamed A class in November 1911, when Navy stopped naming submarines. More powerful Holland. |
B | 3 | 1907 | Last in series of Holland-like submarines. Originally known as Viper class. |
C | 5 | 1910 | Designed by Lawrence York Spear. Originally known as the Octopus class. |
D | 3 | 1910 | Originally known as the Narwhal class. Designed to survive flooding in one compartment. |
E | 2 | 1912 | First US Navy diesel-powered submarine. Known as "pig boats", or "boats", due to foul living quarters and unusual hull shape. |
F | 4 | 1913 | In 1920, the class was designated SS-20–SS-23. |
G | 4 | 1914 | Used gasoline engine. G-1 set the submerged depth record in 1915, 256 feet (78 m). |
H | 9 | 1918 | 3 originally ordered by U.S. Navy. 17 ordered by the Russian Navy. Other 6 bought by U.S. Navy. Known as "pig boats", or "boats", due to hull shape. |
K | 8 | 1912 | Also known as "pig boats", or "boats", due to foul living quarters and unusual hull shape. K-1, K-2, K-5 and K-6 were the first to see action in World War I. |
L | 11 | 1918 | The first US submarines with a deck gun also known as "pig boats", or "boats". Designed for coastal defense. |
M | 1 | 1918 | Double-hull design. Twenty percent larger than the K class. Considered failure by the submarine community. |
N | 7 | 1918 | Known as "pig boats", or "boats", due to foul living quarters and unusual hull shape. Used for coastal patrol. |
O | 16 | 1918 | First submarines with reliable diesel engines. Every man had his own berth and locker. |
AA-1 | 3 | 1922 | Later renamed T class. Prototype "fleet submarines", submarines fast enough (21 knots (11 m/s) to travel with battleships. |

The Gato class of submarines were built for the United States Navy and launched in 1941–1943. Named after the lead ship of the class, USS Gato, they were the first mass-production U.S. submarine class of World War II. Gato‘s name comes from a species of small catshark. Like most other U.S. Navy submarines of the period, ships of the Gato class were given the names of aquatic creatures.

Deep-submergence verhicles (DSVs)
A deep-submergence vehicle (DSV) is a deep-diving crewed submersible that is self-propelled. Several navies operate vehicles that can be accurately described as DSVs. DSVs are commonly divided into two types: research DSVs, which are used for exploration and surveying, and DSRVs (deep-submergence rescue vehicles), which are intended to be used for rescuing the crew of a sunken navy submarine, clandestine (espionage) missions (primarily installing wiretaps on undersea communications cables), or both.DSRVs are equipped with docking chambers to allow personnel ingress and egress via a manhole.
