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.

Experimental use: an example is USS Albacore (AGSS-569), which used an unprecedented hull design. In this list such single boat "classes" are marked with "(unique)".

Pre–World War I

Pre–World War I
Class name No. Laid down Last comm. Notes
Alligator[1] 1 1861 1862 First submarine in the U.S. Navy. Purpose was to protect wooden ships against ironclads.
Holland[2][3] 1 1896 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 April 1900.
Plunger[4][5][6][7] 7 1900 1903 Later renamed A class in November 1911, when Navy stopped naming submarines. Essentially enlarged, more powerful Holland.
B[8][9][10][11] 3 1905 1907 Last in series of Holland-like submarines. Originally known as Viper class.
C[12] 5 1905 1910 Designed by Lawrence York Spear. Originally known as the Octopus class.
D[13] 3 1908 1910 Originally known as the Narwhal class. Designed to survive flooding in one compartment.
E[14] 2 1909 1912 First US Navy diesel-powered submarine. Known as "pig boats", or "boats", due to foul living quarters and unusual hull shape.
F[15] 4 1909 1913 In 1920, the class was designated SS-20–SS-23.
G[16][17][18][19] 4 1909 1914 Used gasoline engine. G-1 (SS-19½) set the submerged depth record in 1915, 256 feet (78 m). G-1 (SS-19½) was given the number 19½ because SS- numbers were given after her decommissioning; she was between SS-19 & SS-20.
H[20][21] 9 1911 1918 3 originally ordered by U.S. Navy. 17 ordered by the Imperial Russian Navy, 11 delivered. Other 6 bought by U.S. Navy. Known as "pig boats", or "boats", due to foul living quarters and unusual hull shape.
K[22][23] 8 1912 1912 Known as "pig boats", or "boats", due to foul living quarters and unusual hull shape. K-1 (SS-32), K-2 (SS-33), K-5 (SS-36), K-6 (SS-37) were the first U.S. submarines to see action in World War I.
L[24] 11 1914 1918 The first US submarines with a deck gun. Known as "pig boats", or "boats", due to foul living quarters and unusual hull shape. Designed for coastal defense.
M-1[25] 1 1914 1918 Double-hull design. Twenty percent larger than the K class. Known as "pig boats", or "boats", due to foul living quarters and unusual hull shape. Considered failure by the submarine community.
N[26] 7 1915 1918 Known as "pig boats", or "boats", due to foul living quarters and unusual hull shape. Used for coastal patrol.
O[27][28] 16 1916 1918 Each cost $550,000. First submarines with reliable diesel engines. Every man had his own berth and locker. Known as "pig boats", or "boats", due to foul living quarters and unusual hull shape. O-11 through O-16 (built by Lake Torpedo Boat Company) also known as the "modified O-class". Modified boats proved to be disappointing and were scrapped in 1930; Lake went out of business in 1925.
AA-1[29] 3 1916 1922 Later renamed T class. Designed for 5,540 miles (8,920 km) at 14 knots (7.2 m/s), but performed 3,000 miles (4,800 km) at 11 knots (5.7 m/s). Prototype "fleet submarines"—submarines fast enough (21 knots (11 m/s)) to travel with battleships. Twice the size of any concurrent or past U.S. submarine. A poor tandem engine design caused the boats to be decommissioned by 1923 and scrapped in 1930.

World War I

Class name No. Laid down Last comm. Notes
R[30][31] 20 1917 1918 Larger conning tower to serve as commanding officer's battle station. Fired Mark 10 torpedoes and traveled 5,000 miles (8,000 km) at 10 knots (5.1 m/s).
R-21[32] 7 1917 1919 Designed by Simon Lake. Generally similar to R class, but smaller and reverted to 18-inch torpedo tubes. Scrapped in 1930; Lake went out of business in 1925.
S 51 1917 1922 The S class is subdivided into four groups of different designs.
