Commander-in-Chief, Western Approaches
Commander-in-Chief, Western Approaches was the commander of a major operational command of the Royal Navy during World War II. The admiral commanding, and his forces, sometimes informally known as 'Western Approaches Command,' were responsible for the safety of British shipping in the Western Approaches. History Admiral Martin Dunbar-Nasmith, who had been Commander-in-Chief, Plymouth, also took over responsibility for the Western Approaches from the start of World War II. After the fall of France in June 1940, the main North Atlantic convoy routes were diverted around the north of Ireland through the north-western approaches.History of Derby House (Western Approaches Museum) accessed 1 May 2017 By late 1940, the location of the Combined Operations headquarters at Plymouth was increasingly awkwar ...

Naval Ensign Of The United Kingdom
The White Ensign, at one time called the St George's Ensign due to the simultaneous existence of a cross-less version of the flag, is an ensign worn on British Royal Navy ships and shore establishments. It consists of a red St George's Cross on a white field, identical to the flag of England except with the Union Flag in the upper canton. The White Ensign is also worn by yachts of members of the Royal Yacht Squadron and by ships of Trinity House escorting the reigning monarch. In addition to the United Kingdom, several other nations have variants of the White Ensign with their own national flags in the canton, with the St George's Cross sometimes being replaced by a naval badge omitting the cross altogether. Yachts of the Royal Irish Yacht Club wear a white ensign with an Irish tricolour in the first quadrant and defaced by the crowned harp from the Heraldic Badge of Ireland. The Flag of the British Antarctic Territory and the Commissioners' flag of the Northern Lighthouse Bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

U-boat
U-boats were naval submarines operated by Germany, particularly in the First and Second World Wars. Although at times they were efficient fleet weapons against enemy naval warships, they were most effectively used in an economic warfare role (commerce raiding) and enforcing a naval blockade against enemy shipping. The primary targets of the U-boat campaigns in both wars were the merchant convoys bringing supplies from Canada and other parts of the British Empire, and from the United States, to the United Kingdom and (during the Second World War) to the Soviet Union and the Allied territories in the Mediterranean. German submarines also destroyed Brazilian merchant ships during World War II, causing Brazil to declare war on both Germany and Italy on 22 August 1942. The term is an anglicised version of the German word ''U-Boot'' , a shortening of ''Unterseeboot'' ('under-sea-boat'), though the German term refers to any submarine. Austro-Hungarian Navy submarines were also kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-submarine Warfare
Anti-submarine warfare (ASW, or in older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades. Successful ASW operations typically involved a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Admiral (Royal Navy)
Admiral is a senior rank of the Royal Navy, which equates to the NATO rank code OF-9, outranked only by the rank of admiral of the fleet. Royal Navy officers holding the ranks of rear admiral, vice admiral and admiral of the fleet are sometimes considered generically to be admirals. The rank of admiral is currently the highest rank to which a serving officer in the Royal Navy can be promoted, admiral of the fleet being in abeyance except for honorary promotions of retired officers and members of the Royal Family. The equivalent rank in the British Army and Royal Marines is general; and in the Royal Air Force, it is air chief marshal. History The first admirals (1224 to 1523) King Henry III of England appointed the first known English Admiral Sir Richard de Lucy on 29 August 1224. De Lucy was followed by Sir Thomas Moulton in 1264, who also held the title of ''Keeper of the Sea and Sea Ports''. Moulton was succeeded by Sir William de Leybourne, (the son of Sir Roger de ...

Huff-Duff
High-frequency direction finding, usually known by its abbreviation HF/DF or nickname huff-duff, is a type of radio direction finder (RDF) introduced in World War II. High frequency (HF) refers to a radio band that can effectively communicate over long distances; for example, between U-boats and their land-based headquarters. HF/DF was primarily used to catch enemy radios while they transmitted, although it was also used to locate friendly aircraft as a navigation aid. The basic technique remains in use to this day as one of the fundamental disciplines of signals intelligence, although typically incorporated into a larger suite of radio systems and radars instead of being a stand-alone system. Earlier systems used a mechanically rotated antenna or solenoid and an operator listening for peaks or nulls in the signal, which often took considerable time to determine the bearing on the order of a minute or more. Later systems used a set of antennas to receive the same signal in slightly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

Naval Tactics In The Age Of Steam
The development of the steam ironclad firing explosive shells in the mid-19th century rendered sailing ship tactics obsolete. New tactics were developed for the big-gun Dreadnought battleships. The Naval mine, mine, torpedo, submarine and aircraft posed new threats, each of which had to be countered, leading to tactical developments such as anti-submarine warfare and the use of dazzle camouflage. By the end of the steam age, aircraft carriers had replaced battleships as the principal unit of the Naval fleet, fleet. Beginnings in the 19th Century The interval of ninety years between the end of the Napoleonic Wars in 1815 and the beginning of the Russo-Japanese War in 1904 was marked by no major naval war. There was fighting at sea, and there were prolonged blockades, but there were no Military campaign, campaigns between large and well-appointed navies. During this period an entire revolution took place in the means of propulsion, armament and construction of ships. Steam was ap ...
