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 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. It has 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 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 3,700 operational aircraft as of June 2019, making it the third-largest air force in the world, after the United States Air Force and the United States Army.
Quincy is the largest city in Norfolk County, Massachusetts, United States. It is part of Metropolitan Boston and one of Boston's immediate southern suburbs. Its population in 2014 was 93,397, making it the eighth-largest city in the state. Known as the "City of Presidents," Quincy is the birthplace of two U.S. presidents—John Adams and his son John Quincy Adams—as well as John Hancock, a President of the Continental Congress and the first signer of the Declaration of Independence, as well as being the 1st and 3rd Governor of Massachusetts.
A harbor or harbour is a sheltered body of water where ships, boats, and barges can be docked. The term harbor is often used interchangeably with port, which is a man-made facility built for loading and unloading vessels and dropping off and picking up passengers. Ports usually include one or more harbors. Alexandria Port in Egypt is an example of a port with two harbors.
Unusually for the early submarine era, the E class boats displaced no more than the 340 tons of the preceding class. The E class was the first US diesel-powered submarine. The French "Z" (Q 36) was the first in the world, in 1905.Although early diesels were unreliable and the E class engines were replaced in 1915, diesels rapidly supplanted gasoline-fueled engines aboard submarines worldwide, to eliminate the substantial risk of gasoline fumes settling into the bilges of the boat at explosive concentrations. Another innovation that became standard was bow planes for greater precision in depth control.
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 US East Coast, before the class was decommissioned and sold for scrap in 1922.
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to the mechanical compression. This contrasts with spark-ignition engines such as a petrol engine or gas engine, which use a spark plug to ignite an air-fuel mixture.
Diving planes, also known as hydroplanes, are control surfaces found on a submarine which allow the vessel to pitch its bow and stern up or down to assist in the process of submerging or surfacing the boat, as well as controlling depth when submerged.
These vessels included some features intended to increase underwater speed that were standard on US submarines of this era, including a small sail and a rotating cap over the torpedo tube muzzles. The streamlined, rotating torpedo tube muzzle cap reduced the drag that an uncovered tube would otherwise cause. In the stowed position, the submarine appeared to have no torpedo tubes, as the holes in the cap were covered by the bow stem. This feature remained standard through the K class, after which it was replaced with shutters that were standard through the 1950s. For extended surface runs, the small sail intended for greater speed underwater was augmented with the temporary piping-and-canvas structure apparent in the photo. The considerable time required to dismantle that structure made "crash" diving the boat impossible, and that impediment remained until its removal with the inception of the N class, commissioned 1917-1918. Experience in World War I showed that this was inadequate in North Atlantic weather, and earlier submarines serving overseas in that war (E class through L class) had the forward structure of the bridge modified with a "chariot" shield. Starting with the N class, built with lessons learned from overseas experience, US submarines had bridges more suited to surfaced operations in rough weather.
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 Seattle Construction and Drydock Company in Seattle, Washington. All were decommissioned in 1923 and scrapped in 1931 to comply with the limits of the London Naval Treaty.
The United States N-class submarines were a class of seven coastal defense submarines built for the United States Navy during World War I.
World War I, also known as the First World War or the Great War, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. Contemporaneously described as "the war to end all wars", it led to the mobilisation of more than 70 million military personnel, including 60 million Europeans, making it one of the largest wars in history. It is also one of the deadliest conflicts in history, with an estimated nine million combatants and seven million civilian deaths as a direct result of the war, while resulting genocides and the resulting 1918 influenza pandemic caused another 50 to 100 million deaths worldwide.
The E class and similar early submarines were known as "pig boats", or "boats", due to foul living quarters and unusual hull shape.The E class was used to test and evaluate tactics and new equipment, but was quickly overtaken by newer long-range, ocean-going submarines. E-1 was forward deployed to the Azores in World War I, the oldest and smallest US submarine to perform war patrols in that war. The class was decommissioned and scrapped in 1922 to comply with the Washington Naval Treaty.
The Azores, officially the Autonomous Region of the Azores, is one of the two autonomous regions of Portugal. It is an archipelago composed of nine volcanic islands in the North Atlantic Ocean about 1,360 km (850 mi) west of continental Portugal, about 1,643 km (1,021 mi) west of Lisbon, in continental Portugal, about 1,507 km (936 mi) northwest of Morocco, and about 1,925 km (1,196 mi) southeast of Newfoundland, Canada.
The Washington Naval Treaty, also known as the Five-Power Treaty, was a treaty signed during 1922 among the major nations that had won World War I, which agreed to prevent an arms race by limiting naval construction. It was negotiated at the Washington Naval Conference, held in Washington, D.C., from November 1921 to February 1922, and it was signed by the governments of the United Kingdom, the United States, France, Italy, and Japan. It limited the construction of battleships, battlecruisers and aircraft carriers by the signatories. The numbers of other categories of warships, including cruisers, destroyers and submarines, were not limited by the treaty, but those ships were limited to 10,000 tons displacement each.
USS E-1 (SS-24) was an E-class submarine of the United States Navy. Originally named Skipjack, the boat was launched on 27 May 1911 by the Fore River Shipyard, Quincy, Massachusetts; sponsored by Mrs. D. R. Battles; renamed E-1 on 17 November 1911; and commissioned on 14 February 1912, Lieutenant Chester W. Nimitz in command. She was the first American submarine to be powered by diesel engines.
Chester William Nimitz, Sr. was a fleet admiral of the United States Navy. He played a major role in the naval history of World War II as Commander in Chief, U.S. Pacific Fleet and Commander in Chief, Pacific Ocean Areas, commanding Allied air, land, and sea forces during World War II.
USS E-2 (SS-25) was an E-class submarine of the United States Navy. Originally named Sturgeon, the boat was launched on 15 June 1911 by the Fore River Shipyard, Quincy, Massachusetts; sponsored by Ms. Margaret Nelson Little; renamed E-2 on 17 November 1911; and commissioned on 14 February 1912, Ensign C. N. Hinkamp in command.
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 Skipjack class was a class of United States Navy nuclear submarines (SSNs) that entered service in 1959-61. This class was named after its lead boat, USS Skipjack. The new class introduced the teardrop hull and the S5W reactor to U.S. nuclear submarines. The Skipjacks were the fastest U.S. nuclear submarines until the Los Angeles-class submarines, the first of which entered service in 1974.
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.
The A class was the Royal Navy's first class of British-designed submarines. Thirteen were built by Vickers at Barrow-in-Furness between 1902 and 1905 as an improvement on the US Plunger class.
The Barracuda-class submarines were the product of Project Kayo, a research and development effort begun immediately after World War II by the United States Navy to "solve the problem of using submarines to attack and destroy enemy submarines." They originally had the hull classification symbol SSK, for "hunter-killer submarine". It was known that the Soviet Navy had acquired the German Type XXI U-boat and other advanced submarines, and was expected to rapidly put derivatives of them into production. In 1948 the US Navy prepared estimates of the number of anti-submarine warfare (ASW)-capable submarines (SSKs) that would be needed to counter the hundreds of advanced Soviet submarines that were expected to be in service by 1960. Two scenarios were considered: a reasonable scenario assuming the Soviets would build to their existing force level of about 360 submarines, and a "nightmare" scenario projecting that the Soviets could build submarines as fast as the Germans had built U-boats, with a force level of 2,000 submarines. The projected US SSK force levels for these scenarios were 250 for the former and 970 for the latter. By comparison, the total US submarine force at the end of World War II, excluding obsolescent training submarines, was just over 200 boats.
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.
USS O-2 (SS-63) was one of 16 O-class submarines built for the United States Navy during World War I.
USS O-4 (SS-65) was one of 16 O-class submarines built for the United States Navy during World War I.
USS L-11 (SS-51) was an L-class submarine of the United States Navy.
The R-class submarines were a class of United States Navy submarines active from 1918 until 1945. With the first of the class laid down following the American entry into World War I, they were built rapidly. Although R-15 through R-20 were completed July–October 1918, they did not serve overseas, and the bulk of the class were not completed until after the Armistice.
The United States Navy's sixteen O-class submarines were created out of the lessons learned from the L class. The O class were about 80 tons larger than the L class, with greater power and endurance for ocean patrols. Due to the American entry into World War I the O class were built much more rapidly than previous classes, and were all commissioned in 1918. O-1 through O-10 were group 1, designed by Electric Boat, O-11 through O-16 were group 2, designed by the Lake Torpedo Boat Company and sometimes considered a separate class. The group 2 boats entered service just before the end of World War I. Eight of the group 1 boats survived to serve in World War II as training boats when they were recommissioned in 1941.
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 Moran Bros. 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 C-class submarines were five United States Navy submarines built by the Fore River Shipbuilding Company in Quincy, Massachusetts, under a subcontract from the Electric Boat Company. Built between 1906 and 1909, and in commission from 1908 to 1919, all five were subsequently sold for scrap in 1920. They were considerably larger than the preceding B class at 275 tons submerged vs. 173 tons submerged, and were the first United States submarines with two-shaft propulsion, doubling the machinery of the B class.
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 was built by Newport News, G-2 and G-3 by Lake, and G-4 by Cramp.
The United States H-class submarines were Holland 602 type submarines used by the United States Navy.
The United States L-class submarines were a class of 11 submarines built 1914–1917, and were the United States Navy's first attempt at designing and building ocean-going submarines. At the time there was a significant gap in long-range submarine design compared with other major navies. The Group 2 L-boats designed by Lake Torpedo Boat Company were built to slightly different specifications from the other Group 1 L-boats and are sometimes considered a separate L-5 class.
