A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a fish. The term torpedo originally applied to a variety of devices, most of which would today be called mines. From about 1900, torpedo has been used strictly to designate a self-propelled underwater explosive device.
Submarine warfare is one of the four divisions of underwater warfare, the others being anti-submarine warfare, mine warfare and mine countermeasures.
A midget submarine is any submarine under 150 tons, typically operated by a crew of one or two but sometimes up to six or nine, with little or no on-board living accommodation. They normally work with mother ships, from which they are launched and recovered and which provide living accommodation for the crew and support staff.
HMS Laforey was the lead ship of her class of destroyer built for the Royal Navy. Launched a year before the First World War began, she was attached to the Dover Patrol. Laforey saw action in several engagements with German torpedo boats, including the Battle off Noordhinder Bank and the action of 17 March 1917. Laforey was sunk in 1917 by a British mine after escorting several freighters to France. She was named for Francis Laforey, captain of HMS Spartiate at the Battle of Trafalgar in 1805.
HMS Porpoise (N14) was one of the six-ship class of Grampus-class mine-laying submarines of the Royal Navy. She was built at Vickers Armstrong, Barrow and launched 30 August 1932. She served in World War II in most of the naval theatres of the war, in home waters, the Mediterranean and the Far East. She was sunk with all hands by Japanese aircraft on 19 January 1945, and was the last Royal Navy submarine to be lost to enemy action.
HMS Rorqual (N74) was a British mine-laying submarine, one of the six ships of the Grampus class of the Royal Navy. She was built by Vickers Armstrong, Barrow and launched 27 July 1936. She served in the Second World War in the Mediterranean and in the far east. She was the only Grampus-class submarine to survive the war, and she is considered the most successful minelaying submarine of World War II, sinking 57,704 GRT of enemy shipping, 35,951 of which through her mines.
The Hansa was a Swedish passenger ship, in use on the route between the Swedish mainland and Visby. She was torpedoed and sunk by a Soviet submarine in 1944, during World War II.
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-boat campaign from 1914 to 1918 was the World War I naval campaign fought by German U-boats against the trade routes of the Allies. It took place largely in the seas around the British Isles and in the Mediterranean. The German Empire relied on imports for food and domestic food production and the United Kingdom relied heavily on imports to feed its population, and both required raw materials to supply their war industry; the powers aimed, therefore, to blockade one another. The British had the Royal Navy which was superior in numbers and could operate on most of the world's oceans because of the British Empire, whereas the Imperial German Navy surface fleet was mainly restricted to the German Bight, and used commerce raiders and unrestricted submarine warfare to operate elsewhere.
SM U-21 was a U-boat built for the Imperial German Navy shortly before World War I. The third of four Type U-19-class submarines, these were the first U-boats in German service to be equipped with diesel engines. U-21 was built between 1911 and October 1913 at the Kaiserliche Werft in Danzig. She was armed with four torpedo tubes and a single deck gun; a second gun was added during her career.
SMS Augsburg was a Kolberg-class light cruiser of the German Kaiserliche Marine during the First World War. She had three sister ships, SMS Kolberg, Mainz, and Cöln. The ship was built by the Kaiserliche Werft in Kiel; her hull was laid down in 1908 and she was launched in July 1909. Augsburg was commissioned into the High Seas Fleet in October 1910. She was armed with a main battery of twelve 10.5 cm SK L/45 guns and had a top speed of 25.5 knots.
The Galeb class, also known as the Orao class, were minelayers originally built as minesweepers for the Imperial German Navy between 1918 and 1919.
Submarine warfare in the Black Sea in World War II during 1941 primarily involved engagements between submarines of the Soviet Black Sea Fleet attacking Axis merchantmen defended by Romanian and Bulgarian warships. These engagements were a part of the naval Black Sea campaigns between Axis and Soviet naval forces.
The Romanian Navy during World War II was the main Axis naval force in the Black Sea campaigns and fought against the Soviet Union's Black Sea Fleet from 1941 to 1944. Operations consisted mainly of mine warfare, but there were also escort missions and localized naval engagements. The largest naval action fought by the Romanian Navy was the 26 June 1941 Raid on Constanța, and its most extensive operation was the 1944 evacuation of the Crimea.
Submarine warfare in the Black Sea in World War II during 1942 involved engagements between primarily submarines of the Soviet Black Sea Fleet attacking Axis merchantmen defended by Romanian and German naval warships. These engagements were a part of the Black Sea campaigns between Axis and Soviet naval forces.
The Soviet submarine Baltic Sea campaign in 1941 was launched by the Soviet Navy at the early stage of Operation Barbarossa. The offensive was hampered by the quick German ground advance and the retreat of Soviet naval vessels from the main Baltic harbors.
The Soviet submarine Baltic Sea campaign in 1944 was launched by the Soviet Navy to harass enemy shipping and naval military assets of the Nazi Germany on the Eastern Front during World War II.
The Soviet naval Baltic Sea campaign in 1945 was launched by the Soviet Navy to harass enemy shipping and naval military assets of Nazi Germany on the Eastern Front during World War II. Both submarines and surface units of the Soviet Navy were employed. The campaign scored successes during Operation Hannibal.
The Barents Sea campaign in 1941 was a submarine operation in the Arctic waters of the Barents Sea during World War II. It was a combined Soviet and British campaign, with boats departing from Polyarny to harass German shipping along the Norwegian coast.
SMS G102 was a G101-class large torpedo boat operated by Imperial German Navy during the First World War. The ship was ordered for the Argentine Navy from the German shipyard Germaniawerft as the San Luis, but was still under construction at the start of the war and was seized by Germany.
