G7a
The G7a(TI) was the standard issue ''Kriegsmarine'' torpedo introduced to service in 1934. It was a steam-powered design, using a wet heater engine burning decaline, with a range of at speed. In 1936, the Kriegsmarine's first electrical powered torpedo was introduced with the G7e(TII). It was replaced beginning in 1942 by the G7e(TIII). The G7a(TI) remained in service as the main torpedo of Kriegsmarine for the length of the war, being the only torpedo used from surface vessels, and alongside electric torpedoes on the uboats. Design The G7a(TI) torpedo was 533.4 mm (21 in) in diameter, 7163 mm (23 ft 6 in) in length (with a type Ka or Kb warhead and Pi1 or Pi2 pistol), the warhead holding a charge of approximately 280 kg (617lbs) of so-called Schießwolle 36. It was Kriegsmarine's first operational torpedo (hence "TI" = Torpedo number one), and the standard issue torpedo for all German U-boats and surface torpedo-bearing vessels from 1934 to the end o ...

G7e Torpedo
The G7e torpedo was the standard electric torpedo used by the German ''Kriegsmarine'' submarines in World War II. It came in 20 different versions, with the initial model G7e(TII) in service at the outbreak of the war. Due to several problems, leading to the German "''Torpedokrise''" which lasted until the end of 1941, the improved G7e(TIII) took over as the standard electric torpedo used by German U-boats for the rest of the war. G7e torpedoes measured in diameter and about in length. Depending on the type, the warhead contained a main charge of of '' Schießwolle 36'', a mixture of dipicrylamine and TNT. All were powered by electric motors and lead-acid batteries which required onboard maintenance to maintain their functionality. Other major G7e-versions that saw operational service during the war, were the first acoustic homing torpedo G7es(TIV) ''Falke'' and its improved successor G7es(TV) ''Zaunkönig''.

Wet Heater
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. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though some ...

SS Fanad Head
SS ''Fanad Head'' was a UK cargo steamship. She was built during the First World War and torpedoed and sunk ten days after the UK entered the Second World War. Building Workman, Clark and Company of Belfast built ''Fanad Head'' for the Ulster Steam Ship Co Ltd (G. Heyn & Sons Ltd). She was completed in 1917 and registered in Belfast. She was named after Fanad, a headland in County Donegal. Sinking Initial attacks and response When the UK entered the Second World War on 3 September 1939 ''Fanad Head'' was in Canada. She sailed from Montreal carrying general cargo and grain to the UK, and on 14 September she was steaming unescorted off the coast of Ireland when at 1323 hours she was sighted by the . The U-boat surfaced and gave chase, and ''Fanad Head'' radioed for assistance. Some west-northwest of Malin Head ''U-30'' fired a shot across the cargo ship's bow from her 88 mm gun, which persuaded ''Fanad Head''s Master, George Pinkerton, to stop.

Convoy
A convoy is a group of vehicles, typically motor vehicles or ships, traveling together for mutual support and protection. Often, a convoy is organized with armed defensive support and can help maintain cohesion within a unit. It may also be used in a non-military sense, for example when driving through remote areas. Naval convoys Age of Sail Naval convoys have been in use for centuries, with examples of merchant ships traveling under naval protection dating to the 12th century. The use of organized naval convoys dates from when ships began to be separated into specialist classes and national navies were established. By the French Revolutionary Wars of the late 18th century, effective naval convoy tactics had been developed to ward off pirates and privateers. Some convoys contained several hundred merchant ships. The most enduring system of convoys were the Spanish treasure fleets, that sailed from the 1520s until 1790. When merchant ships sailed independently, a privateer cou ...

Karl Dönitz
Karl Dönitz (sometimes spelled Doenitz; ; 16 September 1891 24 December 1980) was a German admiral who briefly succeeded Adolf Hitler as head of state in May 1945, holding the position until the dissolution of the Flensburg Government following Germany's unconditional surrender to the Allies days later. As Supreme Commander of the Navy beginning in 1943, he played a major role in the naval history of World War II. He began his career in the Imperial German Navy before World War I. In 1918, he was commanding , and was taken prisoner of war by British forces. While in a POW camp, he formulated what he later called ''Rudeltaktik'' ("pack tactic", commonly called "wolfpack"). By the start of the Second World War, Dönitz was supreme commander of the ''Kriegsmarine'' U-boat arm ( (BdU)). In January 1943, Dönitz achieved the rank of (grand admiral) and replaced Grand Admiral Erich Raeder as Commander-in-Chief of the Navy. Dönitz was the main enemy of Allied naval forces in ...

Scuttling
Scuttling is the deliberate sinking of a ship. Scuttling may be performed to dispose of an abandoned, old, or captured vessel; to prevent the vessel from becoming a navigation hazard; as an act of self destruct, self-destruction to prevent the ship from being captured by an enemy force (or, in the case of a vessel engaged in illegal activities, by the authorities); as a blockship to restrict navigation through a Channel (geography), channel or within a harbor; to provide an artificial reef for divers and marine life; or to alter the flow of rivers. Notable historical examples Skuldelev ships (around 1070) The Skuldelev ships, five Viking ships, were sunk to prevent attacks from the sea on the Danish city of Roskilde. The scuttling blocked a major waterway, redirecting ships to a smaller one that required considerable local knowledge. Cog near Kampen (early 15th century) In 2012, a Cog (ship), cog preserved from the keel up to the decks in the silt was discovered alongside ...
