The Balao class was a design of United States Navy submarine used during World War II, and with 120 boats 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 V-boats were a group of nine United States Navy submarines built between World War I and World War II from 1921 to 1934 under authorization as the "fleet boat" program.
The Plunger class was an early class of United States Navy submarines. In the first years of their service, they were used primarily as training and experimental vessels for the newly formed "silent service" to familiarize naval personnel with the performance and operations of such craft. They were known as the "A class" after being renamed to A-type designations on 17 November 1911. All except Plunger ended up being stationed in the Philippines, an American possession, prior to the outbreak of World War I. They were shipped there on colliers and formed an integral part of the harbor defense system for Manila. In some instances, this class of submarines is referred to as the Adder class, as USS Adder was the first boat of the class to be completed.
USS Adder, later renamed A-2, was one of seven Plunger-class submarines built for the United States Navy (USN) in the first decade of the 20th century.
USS Moccasin (SS-5) was one of seven Plunger-class submarines built for the United States Navy (USN) in the first decade of the 20th century.
The AA-1 class was a class of three experimental submarines of the United States Navy, built toward the end of World War I, between 1916 and 1919, intended to produce a high-speed fleet submarine. The design was not a success and none of the submarines saw active service. However, the lessons learned were applied to the design of the later V-boats. The class was later renamed as the T class.
USS C-1 (SS-9) was the lead ship of her class of submarines built for the United States Navy in the first decade of the 20th century.
USS C-2 (SS-13) was one of five C-class submarines built for the United States Navy in the first decade of the 20th century.
USS C-4 (SS-15) one of five C-class submarines built for the United States Navy in the first decade of the 20th century.
USS C-3 (SS-14) was one of five C-class submarines built for the United States Navy in the first decade of the 20th century.
USS C-5 (SS-16) was one of five C-class submarines built for the United States Navy in the first decade of the 20th century.
USS B-2 (SS-11) was one of three B-class submarines built for the United States Navy in the first decade of the 20th century.
The F-class submarines were a group of four submarines designed for the United States Navy by Electric Boat in 1909. F-1 and F-2 were built by Union Iron Works in San Francisco, while F-3 and F-4 were built by The Moran Company in Seattle, Washington.
The B-class submarines were three United States Navy submarines built by the Fore River Shipbuilding Company in Quincy, Massachusetts, under a subcontract from the Electric Boat Company. They were eventually stationed in the Philippines, an American possession, beginning in 1912–15. They were shipped there on colliers. All three were stricken and expended as targets 1919–22.
The United States D-class submarines were a trio of submarines built for the United States Navy in the first decade of the 20th century. All three ships served during World War I providing training for crews and officers on the U.S. East Coast, before the class was decommissioned and sold for scrap in 1922.
The G-class submarines were a class of four United States Navy submarines. While the four G boats were nominally all of a class, they differed enough in significant details that they are sometimes considered to be four unique boats, each in a class by herself. They were the result of agitation for competition in submarine design; all previous US submarines were designed by Electric Boat. G-1, G-2, and G-3 were designed by Simon Lake of the Lake Torpedo Boat Company, while G-4 was designed by American Laurenti. G-1 and G-2 were built by Newport News, G-3 by Lake, and G-4 by Cramp.
The E-class submarines were a class of two United States Navy submarines, built by the Fore River Shipbuilding Company of Quincy, Massachusetts, under a subcontract from the Electric Boat Company. They were used as coastal and harbor defense submarines prior to World War I. When hostilities broke out, the E class were mostly used as training boats; however, E-1 operated on war patrols based in the Azores. During this time, the need for an improved permanent bridge structure was discovered; the temporary piping-and-canvas bridges were inadequate in the North Atlantic.
The United States H-class submarines were Electric Boat design EB26A and EB26R design coastal patrol submarines used by the United States Navy.
The K-class submarines were a class of eight submarines of the United States Navy, serving between 1914 and 1923, including World War I. They were designed by Electric Boat and were built by other yards under subcontracts. K-1, K-2, K-5, and K-6 were built by Fore River Shipyard in Quincy, Massachusetts, K-3, K-7, and K-8 by Union Iron Works in San Francisco, and K-4 by The Moran Company in Seattle, Washington. All were decommissioned in 1923 and scrapped in 1931 to comply with the limits of the London Naval Treaty.
The U-5 class was a class of three submarines or U-boats that were operated by the Austro-Hungarian Navy before and during World War I. The class was a part of the Austro-Hungarian Navy's efforts to competitively evaluate three foreign submarine designs.
