12th Special Operations Squadron
The 12th Special Operations Squadron is assigned to the 27th Special Operations Group at Cannon Air Force Base, New Mexico. Its mission is the launch and recovery of MQ-9 Reaper Remotely Piloted Aircraft from unprepared locations throughout the world. The squadron was activated in 2015 to replace a detachment that had been performing the same mission since October 2013. The squadron was previously active at Elmendorf Air Force Base, Alaska as the 12th Fighter Squadron, part of the 3d Operations Group. The squadron operated the McDonnell Douglas F-15 Eagle aircraft conducting air superiority missions. The mission of the 12th is to launch and recover Remotely Piloted Aircraft (RPA) operationally employed by the 2d, 3d and 33d Special Operations Squadrons. To avoid the inherent delay in transmitting commands through satellite communications to RPAs from distant stations, the squadron deploys to locations where it can operate the craft for takeoff and landing using line of s ...

Air Force Special Operations Command
Air Force Special Operations Command (AFSOC), headquartered at Hurlburt Field, Florida, is the special operations component of the United States Air Force. An Air Force major command (MAJCOM), AFSOC is also the U.S. Air Force component command to United States Special Operations Command (USSOCOM), a unified combatant command located at MacDill Air Force Base, Florida. AFSOC provides all Air Force Special Operations Forces (SOF) for worldwide deployment and assignment to regional unified combatant commands. Before 1983, Air Force special operations forces were primarily assigned to the Tactical Air Command (TAC) and were generally deployed under the control of U.S. Air Forces in Europe (USAFE) or, as had been the case during the Vietnam War, Pacific Air Forces (PACAF). Just as it had relinquished control of the C-130 theater airlift fleet to Military Airlift Command (MAC) in 1975, TAC relinquished control of Air Force SOF to MAC in December 1982. AFSOC was initially e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Line-of-sight Propagation
Line-of-sight propagation is a characteristic of electromagnetic radiation or acoustic wave propagation which means waves travel in a direct path from the source to the receiver. Electromagnetic transmission includes light emissions traveling in a straight line. The rays or waves may be diffracted, refracted, reflected, or absorbed by the atmosphere and obstructions with material and generally cannot travel over the horizon or behind obstacles. In contrast to line-of-sight propagation, at low frequency (below approximately 3 MHz) due to diffraction, radio waves can travel as ground waves, which follow the contour of the Earth. This enables AM radio stations to transmit beyond the horizon. Additionally, frequencies in the shortwave bands between approximately 1 and 30 MHz, can be refracted back to Earth by the ionosphere, called skywave or "skip" propagation, thus giving radio transmissions in this range a potentially global reach. However, at frequencies abo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satellite Communications
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications s ...

33d Special Operations Squadron
The 33rd Special Operations Squadron is a United States Air Force unit, assigned to the 27th Special Operations Group at Cannon Air Force Base, New Mexico. The squadron operates the General Atomics MQ-9 Reaper. The unit is one of the oldest squadrons in the Air Force, its origins dating to 12 June 1917. Over this time, members of the squadron took part in World War I, World War II, the 1991 Gulf War, Operation Enduring Freedom and Operation Iraqi Freedom. The 33rd SOS was named Air Force Special Operations Command's Special Operations Squadron of the Year for 2012. The squadron was reactivated by the Air Force in May 2009, in view of a perceived need for greater special operations air capacity. First World War The 33rd Special Operations Squadron traces its history to the organization of the 33rd Aero Squadron at Camp Kelly, Texas, on 17 May 1917, about a month after the United States' entry into World War I. The squadron consisted of 160 recruits and was first called "2nd C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2d Special Operations Squadron
The 2nd Special Operations Squadron is an Air Force Reserve Command unit, assigned to the 919th Operations Group. Stationed at Hurlburt Field, Florida, the unit operates General Atomics MQ-9 Reaper remotely piloted vehicles. The unit is one of the oldest units in the United States Air Force, being formed on 25 September 1917 at Fort Omaha, Nebraska. During World War I, the unit was part of the Balloon Section, American Expeditionary Forces, becoming the first American balloon company to reach the Western Front in France and enter combat. The 2nd thus holds the distinction among all USAF units of being "the first complete American air unit in history to operate against an enemy on foreign soil."Schiver, p. 49 It was part of the Army Balloon School after the war, being a balloon training unit until the beginning of World War II. It was later part of the Strategic Air Command during the Cold War. History World War I The unit was initially formed at Fort Omaha, Nebraska as Com ...

McDonnell Douglas F-15 Eagle
The McDonnell Douglas F-15 Eagle is an American twin-engine, all-weather tactical fighter aircraft designed by McDonnell Douglas (now part of Boeing). Following reviews of proposals, the United States Air Force selected McDonnell Douglas's design in 1969 to meet the service's need for a dedicated air superiority fighter. The Eagle first flew in July 1972, and entered service in 1976. It is among the most successful modern fighters, with over 100 victories and no losses in aerial combat, with the majority of the kills by the Israeli Air Force.Spick 2000, p. 127. The Eagle has been exported to Israel, Japan, and Saudi Arabia. The F-15 was originally envisioned as a pure air-superiority aircraft. Its design included a secondary ground-attack capability that was largely unused. The aircraft design proved flexible enough that an improved all-weather strike derivative, the F-15E Strike Eagle, was later developed, entered service in 1989 and has been exported to several nations ...

Remotely Piloted Aircraft
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications.Hu, J.; Bhowmick, P.; Jang, I.; Arvin, F.; Lanzon, A.,A Decentralized Cluster Formation Containment Framework for Multirobot Systems IEEE T ...
