Reacher Satellite Ground Terminal
Reacher is a mobile X‐Band Satellite ground terminal (SGT) acquired by the British Ministry Of Defence, it is designed to replace all medium and large legacy SGTs used in the land environment. It is intended to deliver services through Skynet 5 satellites, and to assist in the transition to TCP/IP network protocol services. Reacher was brought into service in 2007. Secure communications are delivered through the Skynet 5 private finance initiative contract with Airbus Defence and Space (previously Paradigm Secure Communications) in partnership with Information Systems and Services at MoD Corsham. Variants Reacher came initially in three variants, 44 of which were delivered to the military: * Reacher Large, mounted on a MOWAG Duro III vehicle, provides an assured data rate of 8 Mbit/s through a antenna. Reacher Large takes15 minutes to set up and can only be used when stationary. * Reacher Medium is mounted on a MOWAG Duro III 6 x 6 vehicle and provides an assured data rate ...

Satellite Signal Receiver Brief At The Schriever AFB
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by propulsion, ...

Antenna (radio)
In radio engineering, an antenna or aerial is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver. In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic wave In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, which propagate through space and carry momentum and electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visib ...s (radio waves). In Receiver (radio), reception, an antenna intercepts some of the power of a radio wave in order to produce an electric current at its terminals, that is applied to a receiver to be Amplifier, amplified. Antennas are essential components of all radio equipment. An antenna is an array of conductor (material), conductors (Driven element, elements), elect ...

Royal Marines
The Corps of Royal Marines (RM), also known as the Royal Marines Commandos, are the UK's special operations capable commando force, amphibious light infantry and also one of the five fighting arms of the Royal Navy. The Corps of Royal Marines can trace their origins back to the formation of the "Duke of York and Albany's maritime regiment of Foot" on 28 October 1664, and can trace their commando origins to the formation of the 3rd Special Service Brigade, now known as 3 Commando Brigade on 14 February 1942, during the Second World War. As a specialised and adaptable light infantry and commando force, Royal Marine Commandos are trained for rapid deployment worldwide and capable of dealing with a wide range of threats. The Corps of Royal Marines is organised into 3 Commando Brigade and a number of separate units, including 47 Commando (Raiding Group) Royal Marines, and a company-strength commitment to the Special Forces Support Group.

Boeing C-17 Globemaster III
The McDonnell Douglas/Boeing C-17 Globemaster III is a large military transport aircraft that was developed for the United States Air Force (USAF) from the 1980s to the early 1990s by McDonnell Douglas. The C-17 carries forward the name of two previous piston-engined military cargo aircraft, the Douglas C-74 Globemaster and the Douglas C-124 Globemaster II. The C-17 is based upon the McDonnell Douglas YC-15, YC-15, a smaller prototype airlifter designed during the 1970s. It was designed to replace the Lockheed C-141 Starlifter, and also fulfill some of the duties of the Lockheed C-5 Galaxy. Compared to the YC-15, the redesigned airlifter differed in having swept wings, increased size, and more powerful engines. Development was protracted by a series of design issues, causing the company to incur a loss of nearly US$1.5 billion on the program's development phase. On 15 September 1991, roughly one year behind schedule, the first C-17 performed its maiden flight. The C-17 formally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helicopters
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most common h ...

Chinook Helicopter
The Boeing CH-47 Chinook is a tandem rotor helicopter developed by American rotorcraft company Vertol and manufactured by Boeing Vertol. The Chinook is a heavy-lift helicopter that is among the heaviest lifting Western helicopters. Its name, Chinook, is from the Native American Chinook people of Oregon and Washington state. The Chinook was originally designed by Vertol, which had begun work in 1957 on a new tandem-rotor helicopter, designated as the Vertol Model 107 or V-107. Around the same time, the United States Department of the Army announced its intention to replace the piston engine–powered Sikorsky CH-37 Mojave with a new, gas turbine–powered helicopter. During June 1958, the U.S. Army ordered a small number of V-107s from Vertol under the ''YHC-1A'' designation; following testing, it came to be considered by some Army officials to be too heavy for the assault missions and too light for transport purposes. While the YHC-1A would be improved and adopted by the U.S. M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Op Herrick
Operation Herrick was the codename under which all British operations in the War in Afghanistan were conducted from 2002 to the end of combat operations in 2014. It consisted of the British contribution to the NATO-led International Security Assistance Force (ISAF), and support to the American-led Operation Enduring Freedom (OEF), within the central Asian country. Operation Herrick superseded two previous efforts in Afghanistan. The first of these was Operation Veritas, which consisted of support during the United States invasion of Afghanistan in October 2001. The last major action of this was a sweep in east Afghanistan by 1,700 Royal Marines during Operation Jacana, which ended in mid-2002. The second was Operation Fingal, which involved leadership and a 2,000 strong contribution for a newly formed ISAF in Kabul after December 2001. Command was subsequently transferred to NATO ally Turkey several months later and the British contingent was scaled back to 300. Since then, all com ...

Operation Telic
Operation Telic (Op TELIC) was the codename under which all of the United Kingdom's military operations in Iraq were conducted between the start of the invasion of Iraq on 19 March 2003 and the withdrawal of the last remaining British forces on 22 May 2011. The bulk of the mission ended on 30 April 2009 but around 150 troops, mainly from the Royal Navy, remained in Iraq until 22 May 2011 as part of the Iraqi Training and Advisory Mission. 46,000 troops were deployed at the onset of the invasion and the total cost of war stood at £9.24 billion in 2010. Background Operation Telic was one of the largest deployments of British forces since World War II. It was only approached in size by the 1991 Operation Granby deployment for the Gulf War and the 1956 Operation Musketeer Suez Crisis deployment. It was considerably larger than the 1982 Operation Corporate in the Falklands War, which saw around 30,000 personnel deployed and the Korean War, which saw fewer than 20,000 personnel deplo ...

Amphibious Warfare
Amphibious warfare is a type of offensive military operation that today uses naval ships to project ground and air power onto a hostile or potentially hostile shore at a designated landing beach. Through history the operations were conducted using ship's boats as the primary method of delivering troops to shore. Since the Gallipoli Campaign, specialised watercraft were increasingly designed for landing troops, material and vehicles, including by landing craft and for insertion of commandos, by fast patrol boats, zodiacs (rigid inflatable boats) and from mini-submersibles. The term ''amphibious'' first emerged in the United Kingdom and the United States during the 1930s with introduction of vehicles such as Vickers-Carden-Loyd Light Amphibious Tank or the Landing Vehicle Tracked.The first LVT prototypes were named ''Alligator'' and '' Crocodile'', though neither species is actual amphibian Amphibious warfare includes operations defined by their type, purpose, scale an ...
