Charles L
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its depr ...

Bofors 57 Mm L/70 Naval Artillery Gun
Bofors 57 mm Naval Automatic Gun L/70 ( sv, 57 mm sjöautomatkanon L/70 (''57 mm SAK 70'')), among other names (see Names), is a series of dual-purpose naval guns designed and produced by the Swedish arms manufacturer AB Bofors (since March 2005 part of BAE Systems AB), designed in the late 1960s as a replacement design for the twin barreled Bofors 57 mm Naval Automatic Gun L/60. The gun is remotely controlled by a fire-control computer but can as a redundancy measure also be operated manually by crew using instrument panels either on or in direct contact with the gun. The gun has been upgraded and improved several times: *Mk1 – The baseline Mark 1 variant began production in 1970 and was initially used to equip smaller coastal patrol craft and fast attack craft. *Mk2 – The improved Mark 2 variant came in 1981 and drastically lowered the weight as well as introduced new servo stabilizers. *Mk3 – The improved Mark 3 variant came in 1995 and primarily features t ...

High Endurance Cutter
The designation of high endurance cutter (WHEC) was created in 1965 when the United States Coast Guard adopted its own designation system. High endurance cutters encompass the largest cutters previously designated by the United States Navy as gunboats, destroyer escorts, and seaplane tenders. The term High Endurance Cutter may refer to any of five individual ship classes that have seen service in the Coast Guard. *The Legend-class cutter is the newest class in this category. *The is a contemporary design. These vessels are also known as Secretary- or Hero-class cutters.

Integrated Deepwater System Program
The Integrated Deepwater System Program (IDS Program or Deepwater) was the 25-year program to replace all or much of the United States Coast Guard's equipment, including aircraft, ships, and logistics and command and control systems. The $24 billion program (which began with a price tag of $17 billion) lost authorization in Fiscal Year 2012 and is officially defunct. The initial idea was to develop interoperable system which included new cutters and small boats, a new fleet of fixed-wing aircraft, a combination of new and upgraded helicopters, and land- and cutter-based unmanned aerial vehicles (UAVs). All of these assets will be linked with Command, Control, Communications and Computers, Intelligence, Surveillance and Reconnaissance (C4ISR) systems. Performance-based logistics is also an aspect of the contract. History The Coast Guard performs many missions in a deepwater environment, which is usually defined as waters more than 50 nautical miles offshore. These missions inclu ...

HH-65 Dolphin
The Eurocopter MH-65 Dolphin is a twin-engined helicopter operated by the United States Coast Guard (USCG) for medevac-capable search and rescue (SAR) and armed Airborne Use of Force missions. It is a variant of the French-built Eurocopter AS365 Dauphin. Development The SA366 G1 Dauphin version was selected by the United States Coast Guard in 1979 as its new short range recovery (SRR) air-sea rescue helicopter, replacing the Sikorsky HH-52A Sea Guard.

M240 Machine Gun
The M240 – officially the Machine Gun, 7.62 mm, M240 – is the U.S. military designation for the FN MAG, a family of belt-fed, gas-operated medium machine guns that chamber the 7.62×51mm NATO cartridge. The M240 has been used by the United States Armed Forces since the late 1970s. It is used extensively by infantry, most often in rifle companies, as well as on ground vehicles, watercraft and aircraft. Though it is heavier than some comparable weapons, it is highly regarded for reliability and its standardization among NATO members is a major advantage. All variants are fed from disintegrating belts and are capable of firing most types of 7.62 mm (.30/.308 cal) NATO ammunition. M240 variants can be converted to use non-disintegrating belts. There are significant differences in weight and some features among some versions which restrict the interchangeability of parts. The M240s used by the U.S. military are currently manufactured by FN America, the American ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M2 Browning
The M2 machine gun or Browning .50 caliber machine gun (informally, "Ma Deuce") is a heavy machine gun that was designed towards the end of World War I by John Browning. Its design is similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 cartridge. The M2 uses Browning's larger and more powerful .50 BMG (12.7 mm) cartridge. The design has had many designations; the official U.S. military designation for the current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications, and low-flying aircraft. The gun has been used extensively as a vehicle weapon and for aircraft armament by the United States since the 1930s. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan.

CIWS
A close-in weapon system (CIWS ) is a point-defense weapon system for detecting and destroying short-range incoming missiles and enemy aircraft which have penetrated the outer defenses, typically mounted on a naval ship. Nearly all classes of larger modern warships are equipped with some kind of CIWS device. There are two types of CIWS systems. A gun-based CIWS usually consists of a combination of radars, computers, and rapid-firing multiple-barrel rotary cannons placed on a rotating turret. Missile-based CIWSs use either infra-red, passive radar/ ESM, or semi-active radar terminal guidance to guide missiles to the targeted enemy aircraft or other threats. In some cases, CIWS are used on land to protect military bases. In this case, the CIWS can also protect the base from shell and rocket fire. Gun systems A gun-based CIWS usually consists of a combination of radars, computers and rotary or revolver cannon placed on a rotating, automatically aimed gun mount. Examp ...

Nulka
Nulka is an Australian-designed and -developed active missile decoy built by an American/ Australian collaboration. Used aboard warships of the United States Navy (USN), Royal Australian Navy (RAN), United States Coast Guard (USCG), and Royal Canadian Navy, Nulka is a rocket-propelled, disposable, offboard, active decoy designed to lure anti-ship missiles away from their targets. It has a unique design in that it hovers in mid-air while drawing the incoming anti-ship missile. The hovering rocket concept was initiated in Australia by the Defence Science and Technology Organisation (DSTO), and the system was designed, developed and then manufactured by AWA Defence Industries ( AWADI) (now BAE Systems Australia). BAE refers to Nulka as a " soft-kill defence system". The word "Nulka" is of Australian Aboriginal origin and means "be quick". The Nulka consists of the missile itself enclosed in a hermetically sealed canister. This canister is then contained in a dedicated launcher mod ...
