Operation Nimbus Star
Following the Yom Kippur War between Egypt and Israel in 1973, an international agreement was reached in October 1973 to provide measures to reopen the Suez Canal after its closure for 8 years after the 1967 Six-Day War. The U.S.-led clearing effort undertaken in 1974 consisted of three operations: the sweeping of mines in the Suez Canal by naval units from the United States, the United Kingdom and France (Operation Nimbus Star), the provision of training and advisory assistance for land and water explosive ordnance clearance for Egyptian forces (Operation Nimbus Moon) and the removal and salvage of wrecks from the Canal (Operation Nimrod Spar). Operation Nimbus Star Operation Nimbus Star involved the clearance of naval mines and unexploded ordnance from portions of the Suez Canal and its approaches The U.S. Navy amphibious assault ship (later relieved by ) deployed more than a month early with only five days notice, and became the flagship of "Task Force 65" to clear mines f ...

Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of other First W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boeing Vertol CH-46 Sea Knight
The Boeing Vertol CH-46 Sea Knight is a medium-lift tandem-rotor transport helicopter powered by twin turboshaft engines. It was designed by Vertol and manufactured by Boeing Vertol following Vertol's acquisition by Boeing. Development of the Sea Knight, which was originally designated by the firm as the Vertol Model 107, commenced during 1956. It was envisioned as a successor to the first generation of rotorcraft, such as the H-21 "Flying Banana", that had been powered by piston engines; in its place, the V-107 made use of the emergent turboshaft engine. On 22 April 1958, the V-107 prototype performed its maiden flight. During June 1958, the US Army awarded a contract for the construction of ten production-standard aircraft, designated as the YHC-1A, based on the V-107; this initial order was later cut down to three YHC-1As though. During 1961, the US Marine Corps (USMC), which had been studying its requirements for a medium-lift, twin-turbine cargo/troop assault helicopter, ...

Pilot Boat
A pilot boat is a type of boat used to transport maritime pilots between land and the inbound or outbound ships that they are piloting. Pilot boats were once sailing boats that had to be fast because the first pilot to reach the incoming ship got the business. Today, pilot boats are scheduled by telephoning the ship agents/representatives prior to arrival. History Pilots and the work functions of the maritime pilot go back to Ancient Greece and Roman times, when incoming ships' captains employed locally experienced harbour captains, mainly local fishermen, to bring their vessels safely into port. Eventually, in light of the need to regulate the act of pilotage and ensure pilots had adequate insurance, the harbours themselves licensed pilots for each harbour. Although licensed by the harbour to operate within their jurisdiction, pilots were generally self-employed, meaning that they had to have quick transport to get them from the port to the incoming ships. As pilots were of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suez Canal Authority
Suez Canal Authority (SCA) is an Egyptian state-owned authority which owns, operates and maintains the Suez Canal. It was set up by the Egyptian government to replace the Suez Canal Company in the 1950s which resulted in the Suez Crisis. After the UN intervened, the three invading countries (France, Israel, and the United Kingdom) were forced to withdraw. Establishment and organization SCA is an independent authority having legal personality. SCA was established by the nationalization act signed on 26 July 1956 by the Egyptian president Gamal Abdel Nasser. The act at the same time nationalized the Suez Canal Company and transferred all its assets and employees to the SCA established by this act. The head office is located in Ismaïlia. In Port Said the administration building of the earlier Suez Canal Company is used. Its board of directors comprises 14 persons, including the chairman and managing director. Assets, duties and responsibilities SCA owns the Suez Canal and all are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-personnel Mine
Anti-personnel mines are a form of mine designed for use against humans, as opposed to anti-tank mines, which are designed for use against vehicles. Anti-personnel mines may be classified into blast mines or fragmentation mines; the latter may or may not be a bounding mine. The mines are often designed to injure, not kill, their victims to increase the logistical (mostly medical) support required by enemy forces that encounter them. Some types of anti-personnel mines can also damage the tracks on armoured vehicles or the tires of wheeled vehicles. The International Campaign to Ban Landmines has sought to ban mines culminating in the 1997 Ottawa Treaty, although this treaty has not yet been accepted by over 30 countries. Use Anti-personnel mines are used in a similar manner to anti-tank mines, in static "mine fields" along national borders or in defense of strategic positions as described in greater detail in the land mine article. What makes them different from most anti-ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-tank Mine
An anti-tank mine (abbreviated to "AT mine") is a type of land mine designed to damage or destroy vehicles including tanks and armored fighting vehicles. Compared to anti-personnel mines, anti-tank mines typically have a much larger explosive charge, and a fuze designed to be triggered by vehicles or, in some cases, remotely or by tampering with the mine. History First World War The first anti-tank mines were improvised during the First World War as a countermeasure against the first tanks introduced by the British towards the end of the war. Initially they were nothing more than a buried high-explosive shell or mortar bomb with its fuze upright. Later, purpose-built mines were developed, including the Flachmine 17, which was simply a wooden box packed with explosives and triggered either remotely or by a pressure fuze. By the end of the war, the Germans had developed row mining techniques, and mines accounted for 15% of U.S. tank casualties during the Battle of Saint-Mih ...

Land Mine
A land mine is an explosive device concealed under or on the ground and designed to destroy or disable enemy targets, ranging from combatants to vehicles and tanks, as they pass over or near it. Such a device is typically detonated automatically by way of pressure when a target steps on it or drives over it, although other detonation mechanisms are also sometimes used. A land mine may cause damage by direct blast effect, by fragments that are thrown by the blast, or by both. Landmines are typically laid throughout an area, creating a ''minefield'' which is dangerous to cross. The use of land mines is controversial because of their potential as indiscriminate weapons. They can remain dangerous many years after a conflict has ended, harming civilians and the economy. Seventy-eight countries are contaminated with land mines and 15,000–20,000 people are killed every year while many more are injured. Approximately 80% of land mine casualties are civilians, with children as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bomb Disposal
Bomb disposal is an explosives engineering profession using the process by which hazardous Explosive device, explosive devices are rendered safe. ''Bomb disposal'' is an all-encompassing term to describe the separate, but interrelated functions in the military fields of explosive ordnance disposal (EOD) and improvised explosive device disposal (IEDD), and the Public security, public safety roles of public safety bomb disposal (PSBD) and the bomb squad. History The first professional civilian bomb squad was established by Sir Vivian Dering Majendie. As a Major in the Royal Artillery, Majendie investigated an explosion on 2 October 1874 in the Regent's Canal, when the barge 'Tilbury', carrying six barrels of petroleum and five tons of gunpowder, blew up, killing the crew and destroying Macclesfield Bridge and cages at nearby London Zoo. In 1875, he framed The Explosives Bill (proposed law), Act, the first modern legislation for explosives control. He also pioneered many bomb d ...
