British O-class Submarine
The ''Odin''-class submarine (or "O class") was a class of nine submarines developed and built for the Royal Navy (RN) in the 1920s. The prototype, , was followed by two boats originally ordered for the Royal Australian Navy, but transferred to the RN in 1931 because of the poor economic situation in Australia, and six modified boats ordered for the RN. Three modified boats were built for the Chilean Navy as the s in 1929. Design The class was built to replace the ageing L-class submarines which did not have adequate endurance for use in the Pacific Ocean. These boats were theoretically able to dive to , though none were formally tested beyond . Armament consisted of eight torpedo tubes (6 bow, 2 stern) and one gun. The boats were of a saddle tank type with fuel carried in riveted external tanks. These external tanks proved vulnerable to leaking after depth charge A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by bei ...

British L-class Submarine
The British L-class submarine was originally planned under the emergency war programme as an improved version of the British E-class submarine. The scale of change allowed the L class to become a separate class. The armament was increased when the 21-inch torpedoes came into service. The Group 3 boats had two QF 4-inch guns fore and aft of the lengthened conning tower. Also, 76 tons of fuel oil was carried in external wing tanks for the first time in British submarines. Several of the Group 1 boats were configured as minelayers including ''L11'' and ''L12''. In the Group 2 boats, ''L14'', ''L17'' and ''L24'' to ''L27'' were built as minelayers carrying 16 mines but without the two beam torpedo tubes. The introduction of the L class came too late to contribute significantly in World War I. was accidentally depth-charged by three American destroyers in early 1918. torpedoed the German submarine . torpedoed the German destroyer ''S33'' in October 1918 but was sunk by accomp ...

Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive Shock factor, hydraulic shock. Most depth charges use explosive, high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, patrol aircraft, and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, during which they were supplemented, and later largely replaced, by anti-submarine homing torpedoes. A depth charge fitted with a nuclear warhead is also known as a "nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-submarine missile from a s ...

Mediterranean
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide.

Malta
Malta ( , , ), officially the Republic of Malta ( mt, Repubblika ta' Malta ), is an island country in the Mediterranean Sea. It consists of an archipelago, between Italy and Libya, and is often considered a part of Southern Europe. It lies south of Sicily (Italy), east of Tunisia, and north of Libya. The official languages are Maltese and English, and 66% of the current Maltese population is at least conversational in the Italian language. Malta has been inhabited since approximately 5900 BC. Its location in the centre of the Mediterranean has historically given it great strategic importance as a naval base, with a succession of powers having contested and ruled the islands, including the Phoenicians and Carthaginians, Romans, Greeks, Arabs, Normans, Aragonese, Knights of St. John, French, and British, amongst others. With a population of about 516,000 over an area of , Malta is the world's tenth-smallest country in area and fourth most densely populated sovereign cou ...

William Beardmore And Company
William Beardmore and Company was a British engineering and shipbuilding conglomerate based in Glasgow and the surrounding Clydeside area. It was active from 1886 to the mid-1930s and at its peak employed about 40,000 people. It was founded and owned by William Beardmore, later Lord Invernairn, after whom the Beardmore Glacier was named. History Forged steel castings, armour plate and naval guns The Parkhead Forge, in the east end of Glasgow, became the core of the company. It was established by Reoch Brothers & Co in 1837 and was later acquired by Robert Napier in 1841 to make forgings and iron plates for his new shipyard in Govan. Napier was given the contract to build , sister ship to the Royal Navy's first true ironclad warship, . Parkead was contracted to make the armour for her, but failed, so the manager, William Rigby called in William Beardmore Snr, who at the time was superintendent of the General Steam Navigation Company in Deptford, to help.

Gulf Of Taranto
The Gulf of Taranto ( it, Golfo di Taranto; Tarantino: ; la, Sinus Tarentinus) is a gulf of the Ionian Sea, in Southern Italy. The Gulf of Taranto is almost square, long and wide, making it the largest gulf in Italy, and it is delimited by the capes Santa Maria di Leuca (to the east, in Apulia) and Colonna (the ancient ''Lacinium'', to the west, in Calabria), encompassed by the three regions of Apulia, Basilicata and Calabria. The most important rivers are the Basento, the Sinni, and the Agri. The main cities on the gulf are Taranto and Gallipoli. Also the Greek colonies (Magna Graecia) of Kroton, Heraclea, Thurii, and Sybaris were founded on the Gulf of Taranto. Italy claims the whole gulf as national waters, thus closed to international traffic. This position, which is similar to that of Libya on the Gulf of Sidra, is not recognized by some other countries, such as the United States and the United Kingdom The United Kingdom of Great Britain and Northern Ireland ...

Friendly Fire
In military terminology, friendly fire or fratricide is an attack by belligerent or neutral forces on friendly troops while attempting to attack enemy/hostile targets. Examples include misidentifying the target as hostile, cross-fire while engaging an enemy, long range ranging errors or inaccuracy. Accidental fire not intended to attack enemy/hostile targets, and deliberate firing on one's own troops for disciplinary reasons, is not called friendly fire,Regan, Geoffrey (2002) ''Backfire: a history of friendly fire from ancient warfare to the present day'', Robson Books and neither is unintentional harm to civilian or neutral targets, which is sometimes referred to as collateral damage. Training accidents and bloodless incidents also do not qualify as friendly fire in terms of casualty reporting. Use of the term "friendly" in a military context for allied personnel started during the First World War, often when shells fell short of the targeted enemy. The term ''friendly fire'' ...

Chatham Dockyard
Chatham Dockyard was a Royal Navy Dockyard located on the River Medway in Kent. Established in Chatham in the mid-16th century, the dockyard subsequently expanded into neighbouring Gillingham (at its most extensive, in the early 20th century, two-thirds of the dockyard lay in Gillingham, one-third in Chatham). It came into existence at the time when, following the Reformation, relations with the Catholic countries of Europe had worsened, leading to a requirement for additional defences. Over 414 years Chatham Royal Dockyard provided more than 500 ships for the Royal Navy, and was at the forefront of shipbuilding, industrial and architectural technology. At its height, it employed over 10,000 skilled artisans and covered .
