The Amphion class of British diesel-electric submarines were designed for use in the Pacific War. Only two were completed before the end of hostilities, but following modernisation in the 1950s, they continued to serve in the Royal Navy into the 1970s.
An attack submarine or hunter-killer submarine is a submarine specifically designed for the purpose of attacking and sinking other submarines, surface combatants and merchant vessels. In the Soviet and Russian navies they were and are called "multi-purpose submarines". They are also used to protect friendly surface combatants and missile submarines. Some attack subs are also armed with cruise missiles, increasing the scope of their potential missions to include land targets.
The Russian Navy is the naval arm of the Russian Armed Forces. It has existed in various forms since 1696; its present iteration was formed in January 1992 when it succeeded the Navy of the Commonwealth of Independent States.
The Victor class, Soviet designations Project 671 Yorsh, Project 671RT Syomga and Project 671RTM/RTMK Shchuka,, are series of nuclear-powered attack submarines built in the Soviet Union and operated by the Soviet Navy. Since the 1960s, 48 units were built in total, of which the last remaining are currently in service with the Russian Navy. The Victor-class submarines featured a teardrop shape, allowing them to travel at high speed. These vessels were primarily designed to protect Soviet surface fleets and to attack American ballistic missile submarines. Project 671 began in 1959 with the design task assigned to SKB-143.
The Akula class, Soviet designation Project 971 Shchuka-B is a series of fourth generation nuclear-powered attack submarines (SSNs) first deployed by the Soviet Navy in 1986. There are four sub-classes or flights of Shchuka-B, consisting of the original seven Project 971 boats, commissioned between 1984 and 1990; six Project 971Is, commissioned between 1991 and 2009; one Project 971U, commissioned in 1995; and one Project 971M, commissioned in 2001. The Russians call all of the submarines Shchuka-B, regardless of modifications.
The Soviet Navy was the naval warfare uniform service branch of the Soviet Armed Forces. Often referred to as the Red Fleet, the Soviet Navy made up a large part of the Soviet Union's strategic planning in the event of a conflict with the opposing superpower, the United States, during the Cold War (1945–1991). The Soviet Navy played a large role during the Cold War, either confronting the North Atlantic Treaty Organization in western Europe or power projection to maintain its sphere of influence in eastern Europe.
The Baltic Sea Campaigns were conducted by Axis and Allied naval forces in the Baltic Sea, its coastal regions, and the Gulf of Finland on the Eastern Front of World War II. After early fighting between Polish and German forces, the main combatants were the Kriegsmarine and the Soviet Navy, with Finland supporting the Germans until 1944 and the Soviets thereafter. The Swedish Navy and merchant fleet played important roles, and the British Royal Navy planned Operation Catherine for control of the Baltic Sea and its exit choke point into the North Sea.
The Bulgarian Navy is the navy of the Republic of Bulgaria and forms part of the Bulgarian Armed Forces. It has been largely overlooked in the reforms that Bulgaria had to go through in order to comply with NATO standards, mostly because of the great expense involved and the fact that naval assaults are not considered to be a great concern for the country's security. That is why three of the four Romeo-class submarines are now docked and have been out of operation for some time. The last one was decommissioned in November 2011. Only the more modern frigates, corvettes and missile crafts are on active duty.
The S-class or Srednyaya submarines were part of the Soviet Navy's underwater fleet during World War II. Unofficially nicknamed Stalinets, boats of this class were the most successful and achieved the most significant victories among all Soviet submarines. In all, they sank 82,770 gross register tons (GRT) of merchant shipping and seven warships, which accounts for about one-third of all tonnage sunk by Soviet submarines during the war.
The Dekabrist class, also known as Series I, were the first class of submarines built for the Soviet Navy after the October Revolution of 1917. They were authorized in the Soviet Naval Shipbuilding Program of 1926, marking the revival of submarine design in Russia. They were authorized in the Soviet Naval Shipbuilding Program of 1926, and began their sea trials in 1930.
The Leninets or L class were the second class of submarines to be built for the Soviet Navy. Twenty-five were built in four groups between 1931 and 1941. They were minelaying submarines and were based on the British L-class submarine, HMS L55, which was sunk during the British intervention in the Russian Civil War. Some experience from the previous Dekabrist-class submarines was also utilised. The boats were of the saddle tank type and mines were carried in two stern galleries as pioneered on the pre-war Russian submarine Krab (1912), the world's first minelaying submarine. These boats were considered successful by the Soviets. Groups 3 and 4 had more powerful engines and a higher top speed.
The Shchuka-class submarines, also referred to as Sh or Shch-class submarines, were a medium-sized class of Soviet submarines, built in large numbers and used during World War II. "Shchuka" is Russian for pike. Of this class, only two submarines entered service after 1945, although they were launched before the war.
The Black Sea Campaigns were the operations of the Axis and Soviet naval forces in the Black Sea and its coastal regions during World War II between 1941 and 1944, including in support of the land forces.
The U-20 class was a class of four submarines or U-boats built for and operated by the Austro-Hungarian Navy during World War I. The class is sometimes referred to as the Havmanden class because it was based upon the design of the Royal Danish Navy's 1911 Havmanden-class submarines, three of which were built in Fiume.
The Korean People's Army Navy or the Korean People's Navy (KPN), is the naval component of the Korean People's Army, the North Korean armed forces.
The Pacific Fleet is the Russian Navy fleet in the Pacific Ocean.
Arctic naval operations of World War II were the World War II naval operations that took place in the Arctic Ocean, and can be considered part of the Battle of the Atlantic and/or of the European Theatre of World War II.
Soviet submarine K-1 was a K-class submarine of the Soviet Navy during World War II.
