The Vigilant Eagle Airport Protection System is a proposed directed-energy weapon under development by the U.S. military under a Defense Department contract with Raytheon. It would create an invisible microwave dome around an airport that could block missiles heading toward incoming and outgoing aircraft. [1]
Man-portable air-defense systems (MANPADS) are shoulder-launched surface-to-air missiles (SAMs) that present a substantial threat to civilian and military aircraft. The U.S. government says these type of weapons have been used in at least 36 attacks on civilian aircraft in the past three decades. [2]
Raytheon has experimented with directed energy weapons since the inadvertent production of the first microwave oven during testing in 1958.
Raytheon CEO William Swanson has described a greater focus on directed energy systems in recent years. [3]
Raytheon Missile Systems developed Vigilant Eagle under a U.S. Defense Department contract and has discussed with the Department of Homeland Security, the potential of using it at U.S. airports. [1] In 2006, a $4.1 million contract with the Department of Homeland Security was issued to assess the anti-missile system. [4]
Within the last three years, the company's researchers have shot down multiple types of shoulder-fired antiaircraft missiles at a distance of several miles with pulses of microwave energy. The company says that its prototype high-power microwave (HPM) weapon, with an energy focused to within 1 degree, sends an electrical pulse which penetrates through openings in the missile's metal parts and reaches its computers and guidance system. This energy is powerful enough to damage electrical components and scramble computer chips, causing the missile to fly off course. [3] Raytheon has tested the system at an American airport, but both the company and the airport are unwilling to disclose which one because of a confidentiality agreement. [1]
The VE works by directing electromagnetic radiation; specifically, a set of high-frequency microwaves toward any projectile fired at an aircraft that is either taking off or landing. For example, if someone were to launch a shoulder-fired projectile or missile from outside the airport during an aircraft's takeoff, the VE airfield would detect the missile's presence and would shoot a microwave beam to deflect it from the airfield. [1]
Vigilant Eagle consists of three major components: a missile detecting and tracking subsystem (MDT), a command and control system, and a scanning array. The MDT is a fixed grid of passive infrared (IR) cameras. The command and control system determines where the launch of the projectile is taking place. Using the scanning array, it can interfere with the MANPAD's guidance system and deflect it away from the aircraft. [5]
The company claims that the system would offer much lower costs than other defense systems claiming $5-11 billion in savings if it were implemented at the 31 busiest U.S. airports. [3]
Airline carriers prefer a ground-based system because it avoids the weight and cost of airplane-mounted systems. [6]
The FIM-92 Stinger is an American man-portable air-defense system (MANPADS) that operates as an infrared homing surface-to-air missile (SAM). It can be adapted to fire from a wide variety of ground vehicles, and from helicopters and drones as the Air-to-Air Stinger (ATAS). It entered service in 1981 and is used by the militaries of the United States and 29 other countries. It is principally manufactured by Raytheon Missiles & Defense and is produced under license by Airbus Defence and Space in Germany and by Roketsan in Turkey.
The Raytheon Company was a major U.S. defense contractor and industrial corporation with manufacturing concentrations in weapons and military and commercial electronics. It was previously involved in corporate and special-mission aircraft until early 2007. Raytheon was the world's largest producer of guided missiles. In April 2020, the Raytheon Company merged with United Technologies Corporation to form Raytheon Technologies, which changed its name to RTX Corporation in July 2023.
Shoulder-fired missile, shoulder-launched missile or man-portable missile, among other variants, are common slang terms to describe high-caliber shoulder-mounted weapons systems; that is, weapons firing large, heavy projectiles ("missiles"), typically using the backblast principle, which are small enough to be carried by a single person and fired while held on one's shoulder. The word "missile" in this context is used in its original broad sense of a heavy projectile, and encompasses all shells and rockets, guided or unguided. A more formal variant is simply shoulder-fired weapons system and the like.
A directed-energy weapon (DEW) is a ranged weapon that damages its target with highly focused energy without a solid projectile, including lasers, microwaves, particle beams, and sound beams. Potential applications of this technology include weapons that target personnel, missiles, vehicles, and optical devices.
The RIM-116 Rolling Airframe Missile (RAM) is a small, lightweight, infrared homing surface-to-air missile in use by the German, Japanese, Greek, Turkish, South Korean, Saudi Arabian, Egyptian, Mexican, UAE, and United States navies. It was originally intended and used primarily as a point-defense weapon against anti-ship missiles. As its name indicates, RAM rolls as it flies. The missile must roll during flight because the RF tracking system uses a two-antenna interferometer that can measure phase interference of the electromagnetic wave in one plane only. The rolling interferometer permits the antennas to look at all planes of incoming energy. In addition, because the missile rolls, only one pair of steering canards is required. As of 2005, it is the only U.S. Navy missile to operate in this manner.
A ranged weapon is any weapon that can engage targets beyond hand-to-hand distance, i.e. at distances greater than the physical reach of the user holding the weapon itself. The act of using such a weapon is also known as shooting. It is sometimes also called projectile weapon or missile weapon because it typically works by launching solid projectiles ("missiles"), though technically a fluid-projector and a directed-energy weapon are also ranged weapons. In contrast, a weapon intended to be used in hand-to-hand combat is called a melee weapon.
Man-portable air-defense systems are portable surface-to-air missiles. They are guided weapons and are a threat to low-flying aircraft, especially helicopters.
The Anza is a series of shoulder-fired, man-portable surface-to-air missiles produced by Pakistan. Guided by an infrared homing seeker, the Anza is used for short range air defence.
A laser weapon is a type of directed-energy weapon that uses lasers to inflict damage. Whether they will be deployed as practical, high-performance military weapons remains to be seen. One of the major issues with laser weapons is atmospheric thermal blooming, which is still largely unsolved. This issue is exacerbated when there is fog, smoke, dust, rain, snow, smog, foam, or purposely dispersed obscurant chemicals present. In essence, a laser generates a beam of light that requires clear air or a vacuum to operate.
An infrared countermeasure (IRCM) is a device designed to protect aircraft from infrared homing missiles by confusing the missiles' infrared guidance system so that they miss their target. Heat-seeking missiles were responsible for about 80% of air losses in Operation Desert Storm. The most common method of infrared countermeasure is deploying flares, as the heat produced by the flares creates hundreds of targets for the missile.
Counter rocket, artillery, and mortar, abbreviated C-RAM or counter-RAM, is a set of systems used to detect and/or destroy incoming rockets, artillery, and mortars before they hit their targets, or provide early warning.
The Northrop Grumman Guardian is a passive anti-missile countermeasure system designed specifically to protect commercial airliners from shoulder-launched missiles, using directed infrared countermeasures (DIRCM) technology.
FN-6 or Feinu-6 is a third-generation passive infrared homing (IR) man portable air defence system (MANPADS). Development from HN-5 missile, FN-6 missile is an export-oriented product and China's most advanced surface-to-air missile offered on the international market. Specially designed to engage low-flying targets, it has a range of 6 km and a maximum altitude of 3.8 km. The missile has been exported to Malaysia, Cambodia, Sudan, Pakistan, and Peru, and a variant was incorporated into People's Liberation Army (PLA) service as the HN-6. Based on FN-6, China has several numbers of other MANPADS and other vehicle-based short-range air defense systems.
A kinetic energy weapon is a projectile weapon based solely on a projectile's kinetic energy to inflict damage to a target, instead of using any explosive, incendiary/thermal, chemical or radiological payload. All kinetic weapons work by attaining a high flight speed — generally supersonic or even up to hypervelocity — and collide with their targets, converting its kinetic energy and relative impulse into destructive shock waves, heat and cavitation. In kinetic weapons with unpowered flight, the muzzle velocity or launch velocity often determines the effective range and potential damage of the kinetic projectile.
The Counter-electronics High Power Microwave Advanced Missile Project (CHAMP) is a joint concept technology demonstration led by the Air Force Research Laboratory, Directed Energy Directorate at Kirtland Air Force Base to develop an air-launched directed-energy weapon capable of incapacitating or damaging electronic systems by means of an EMP.
United States Army air defense relies on a range of ground launched missiles, ranging from hand held to vehicle mounted systems. The Air Defense Artillery is the branch that specializes in anti-aircraft weapons. In the US Army, these groups are composed of mainly air defense systems such as the PATRIOT Missile System, Terminal High Altitude Air Defense, and the Avenger Air Defense system which fires the FIM-92 Stinger missile.
The GBU-53/B StormBreaker, previously known as the Small Diameter Bomb II, is an American air-launched, precision-guided glide bomb.
CIRCM, the Common Infrared Countermeasures program, is a United States Army initiative intended to develop a lightweight, low-cost and modular laser-based infrared protection system for U.S. helicopters and light fixed-wing aircraft. The technology will primarily provide defense against shoulder-fired, heat-seeking missiles, or MANPADS. The program is being developed to replace older suites such as the Advanced Threat Infrared Countermeasures (ATIRCM).
