13 Todd South, Soldiers in Europe are now Using Lasers to Shoot Down Drones, ArmyTimes.com, February 8, 2018, available at < https://www.armytimes.com/news/your-army/2018/02/28/soldiers-in-europe-are-now-using-lasers-to-shoot-down-drones/>. The Russian Stupor is reported to have a range of two kilometers, covering a 20-degree sector; it also suppresses the drone's cameras. Directed energy weapons are among the high-tech arms of the century. However, the Army felt the fixed-base laser system was too large and cut funding for the program after the demonstration phase. When they return to their normal or ground state, the electrons emit photons (particles of light). and and directed energy weapons exist in the medical profession and in society at large. What are the challenges and next steps? Laser weapons potentially eliminate many logistical problems in terms of ammunition supply, as long as there is enough energy to power them. [6], Because they were invented several decades ago, lasers are the most mature of the DEW technologies. These waves penetrate only a few millimeters into the skin and cause the sensation of heat. [24] Would the permanent blinding of a soldier struck by a ZM-87's laser beam be considered intentional or accidental? The Active Denial System (ADS) is a non-lethal directed-energy weapon developed by the U.S. military, designed for area denial, perimeter security and crowd control. low-cost per shot compared to traditional munitions. The Air Force Research Lab's Propulsion Directorate has studied using generators that use high-temperature superconducting wire and high-voltage capacitors. In the Star Wars movies, a wide variety of directed energy weapons are depicted, from handheld light sabers to massive, spaceship-mounted laser cannons. Havana syndrome is a set of medical symptoms reported by US personnel in Havana, Cuba and other locations, suspected by the National Academies of Sciences, Engineering, and Medicine to be caused by microwave energy. This produces a burning pain without actually damaging the tissue. The death ray of science fiction may in fact become a reality in the not too distant future. [1][2] In the United States, the Pentagon, DARPA, the Air Force Research Laboratory, United States Army Armament Research Development and Engineering Center, and the Naval Research Laboratory are researching directed-energy weapons to counter ballistic missiles, hypersonic cruise missiles, and hypersonic glide vehicles. Albert Einstein described the theoretical underpinnings of lasers in 1917. The pain forces the person to flee the area. Directed energy weapons could also play a key role in defending against what has been described as the number one threat to the United States by the Undersecretary of Defense for Research and Engineering Dr. Mike Griffinhypersonic weapons. For example, lasers can cut through steel, aluminum, and many other materials in a matter of seconds. [71] The negative effects of the radiation poisoning and cancer would extend past the period of incarceration. They are real and are maturing rapidly. Building a Stryker with a 50kW laser is a follow-on to the 5kW laser the Army tested on the vehicle just a year ago in Germany at the Joint Warfighting Assessment and related efforts. The soldier returned a short time later to say that the engine would now work and the tourists drove off. Some attempts to replicate this feat have had some success; in particular, an experiment by students at MIT showed that a mirror-based weapon was at least possible, if not necessarily practical. However, no military has yet openly deployed HPM weapons. A prototype ADS system mounted on a Humvee went into testing in August 2005. In early versions of laser weapons, the light was generated by chemical reactions. [81] After the end of the Cold War, the Terra-3 facility was found to be a low-power laser testing site with limited satellite tracking capabilities, which is now abandoned and partially disassembled. [56] Their weapons capability has been controversially used in the USA to disrupt numerous protests. In this last factor, the frequency of the laser and the engagement altitude will have a significant impact on how much the atmosphere effects the lasers lethality. These technologies need the full support of the armed services, and the Department of Defense (DOD) needs to generate clear guidelines for their use. This technology delivers very high-frequency millimeter-wavelength electromagnetic rays that heat skin on contact, causing a painful burning sensation. It was a psychological warfare method which could involve the group based and systematic gaslighting of targets, among other things. They seemed to have arisen from the testing of the television transmitter in Feldberg, Germany. Both the Allies and the Axis powers conducted basic research and studies into primitive directed-energy weapons before World War II. When the LaWS was being integrated onto the ship, the designers and developers envisioned that it would be used several hours a day. HPM lethality can be affected by atmospheric conditions as well, but to a much lesser degree than high-energy laser (HEL) weapons. For example, atmospheric conditions such as turbulence, haze, clouds, etc. Rifle, bazooka and mortar rounds easily deformed the parabolic reflectors, rendering the wave amplification ineffective.[64]. A demonstration system was tested at Kirtland Air Force Base in 2000. In the late Middle Ages, a revolution in the weaponry occurred when chemical-powered (gunpowder) weapons began to replace swords and bows. They will be deployed on land vehicles, aircraft, helicopters, and ships. High-energy lasers (HEL) can range from a few kilowatts to megawatts of average power. The power levels are driven by prime power generation limitations, and ERPs depend on the antenna design and aperture (i.e., size).6, Almost everyone has probably experienced the lethality of a microwave device when they inadvertently put a metal object into a kitchen microwave oven and watched the sparks fly. This same energy can be applied at higher powers for weapon effects. [46] Potentially lethal effects are produced only inside 100 meters range, and disruptive effects at distances on the order of one kilometer. These systems of missile defense are expected to come online no sooner than the mid to late-2020s. In August 2004, the THEL system shot down multiple mortar rounds during testing. DEWs send energy, instead of matter, toward a target, and can be separated into three types: laser weapons, particle-beam weapons, and high-power microwave (HPM) or ra-dio-frequency (RF) weapons. Imagine how much the geopolitical calculus would change on the peninsula if a layered, integrated system of high energy lasers and high-power microwave weapons was deployed to defend against these threats. The Pentagon believes that DEWs are legal under international law, but human rights groups are arguing that DEWs could be used inhumanely. 16 R. Jeffrey Smith, Hypersonic Missiles Are Unstoppable and Theyre Starting a New Global Arms Race, New York Times Magazine, June 19, 2019. [11], The megawatt-class laser was tested at full power in early 2006. While not a rifle or gun, it is so nicknamed as it is handled in the same way as a personal rifle. 11 Megan Eckstein, Navy to Field High-Energy Laser Weapon, Laser Dazzler on Ships This Year as Development Continues, USNI News, May 30, 2019. [2], During the Cold War, the U.S. and the Soviet Union studied the possibility of creating particle-beam weapons, which fire streams of electrons, protons, neutrons, or even neutral hydrogen atoms. [21]U.S. Air Force Research Laboratory, "Active Denial System," fact sheet, September 2005, at http://www.de.afrl.af.mil/Factsheets/ActiveDenial.swf (March 15, 2006). Retrieved 2010-01-04. First up is the Multi-Mission High Energy Laser, a 50-killowatt retrofit to a modified Stryker vehicle, which is expected to be operational in 2023. He has pressed for the development of hypersonic weapons by the United States as well as a defense against them. The full system will be fitted to the aircraft by 2007 and test-fired against ground targets. [6]GlobalSecurity.org, "Patriot Advanced Capability-3 (PAC-3)," at http://www.globalsecurity.org/space/systems/patriot-ac-3.htm (March 15, 2006). In most cases, the target system must be shut off and restarted, and may require minor repairs before it can operate normally again. The antenna gain of the weapon system is also very important, and when combined with the power of the RF source, yields the Effective Radiated Power (ERP) of the weapon. [37] Some examples of weapons which have been publicized by the military are as follows: Active Denial System is a millimeter wave source that heats the water in a human target's skin and thus causes incapacitating pain. This produces a burning pain without actually damaging the tissue. Boeing has received a C-130H transport aircraft from the Air Force and is modifying it for installation of the laser system. These high-speed missiles fly at Mach 5 (five times the speed of sound) and greater. In addition, the Air Force has partnered with the Navy in the development of a high-power RF weapon called High-power Joint Electromagnetic Non-Kinetic Strike (HiJENKS) capable of attacking electronics, communications and computer networks. It stresses the heart, causes insomnia, completely prevents deep sleep, and causes severe muscle aches. Certain types of particle beams have the advantage of being self-focusing in the atmosphere. This damage may create permanent effects depending upon the severity of the attack and the ability of the enemy to diagnose, replace, or repair the affected systems. At 200 yards away, body temperature increases from the normal 98.6 F to 107 F. At closer range, the temperature increase can be even higher, and is lethal. [61][62], Stories in the 1930s and World War Two gave rise to the idea of an "engine-stopping ray". A DE weapon is a system using DE primarily as a direct means to disable, damage or destroy adversary equipment, facilities, and personnel. This In Focus discusses a selection of [66], In 1973, New Scientist magazine reported that a sonic weapon known as a 'squawk box' underwent successful field trials in Northern Ireland, using soldiers as guinea pigs. There is no injury to the target individual. Depending on factors such as burst height, microwave frequency, and the shielding around the target electronics, such an e-bomb could have an effective range of several hundred meters.

While directed-energy research is advancing, inadequate funding is hindering more rapid development and deployment of these technologies. 8, No. [45], AESA radars mounted on fighter aircraft have been slated as directed energy weapons against missiles, however, a senior US Air Force officer noted: "they aren't particularly suited to create weapons effects on missiles because of limited antenna size, power and field of view". [79][80] At the time, the Soviet Union was concerned that the shuttle was being used as a reconnaissance platform. In addition, the cost per shot of a directed energy weapons could be orders of magnitude less expensive than current kinetic weapons. [8], In August 2004, the THEL system shot down multiple mortar rounds during testing. The first step in this endeavor is underway with funding for laser scaling and beam quality improvements for both combined fiber lasers as well as hybrid lasers such as the diode pumped alkali laser or DPALS. The brave men and women who confront dangerous threats across all physical domainsland, air, sea, and spaceneed nothing less than the worlds most promising new capabilities to protect U.S. national security. However, a stronger counterargument is that directed-energy weapons, especially lasers, are more humane than conventional weapons because they can strike pinpoint targets, thus causing less collateral damage. [18]Carlo Kopp, "The Electromagnetic Bomb-A Weapon of Electrical Mass Destruction," at http://www.globalsecurity.org/military/library/report/1996/apjemp.htm (March 15, 2006). Weapons designed to cause undue suffering are banned under the Geneva Convention, and human rights groups argue that directed-energy weapons raise a host of new legal and moral concerns that do not apply to previous generations of conventional weapons. Lasers produce narrow, single-frequency (i.e., single-color), coherent beams of light that are much more powerful than ordinary light sources. The United States must realize that it has to resource the development and fielding of these capabilities. The military has rhetorically embraced the wonders of DEWs, but it has not always opened its wallet to fund the technologies. When a laser beam strikes a target, the energy from the photons in the beam heats the target to the point of combustion or melting. Millimeter waveband energy can penetrate human skin to a very shallow depth, heating the tissue below. For example, in 2005 the cruise liner Seabourn Spirit used a sonic weapon to defend itself from Somali pirates in the Indian ocean. Semiconductors and modern electronics are particularly susceptible to HPM attacks. [citation needed], Another approach was Ernst Schiebolds 'Rntgenkanone' developed from 1943 in Groostheim near Aschaffenburg. When directed at humans, a microwave weapon causes atoms to vibrate, which in turn generates heat. A mechanized unit advancing through a town, protected by an anti-artillery and anti-missile laser shield, clearing the surrounding buildings of snipers and enemy troops with an active denial system, and using electrolasers to stun them before taking them prisoner, all while using HPM weapons to render the enemy's communications useless, would be a powerful military unit indeed. This concentrated energy can have effects across the entire spectrum from non-lethal to lethal. True support for a program is often best measured by the resources that an organization is willing to devote to it. In 1935, the British Air Ministry asked Robert Watson-Watt of the Radio Research Station whether a "death ray" was possible. The laser is being built and will be tested in mid-2006. The weapon's long-range capabilities limit opportunities for the user to assess on-the-ground conditions, potentiating the risk for its inappropriate or disproportionate use. Similar to the Armys RCCTO and the Navys Accelerated Acquisition (AA) Process, the Air Force is leveraging both Air Force Research Laboratorys DE Directorate and Air Force Strategic Development Planning and Experimentation Office to expedite delivery of capabilities to address key capability gaps identified in the DE flight plan: Forward Base Defense, Precision Strike, and Aircraft Self-Protect. LRAD systems are used for long-range communications in a variety of applications[53] and as a means of non-lethal, non-projectile crowd control. Because of its coherence, laser light can stay concentrated for very long distanceseven thousands of miles into space. The distinction between them is the wavelength/frequency of the energy. In addition, a laser shot (including the cost of producing the energy) is much cheaper than a shot from a chemical-powered weapon system. For example, the MDR proposes that the Missile Defense Agency study the potential to develop and field space-based lasers to intercept ballistic missiles.15. For example, when deployed, the anti-ballistic missile Airborne Laser will cost approximately $1,000 per shot. A directed-energy weapon (DEW) is a ranged weapon that damages its target with highly focused energy, including laser, microwaves and particle HPM weapon technology is based on the same technology as radar devices, which already have a long history of research and development. This information is then transferred to an optical tracking system, which refines the target tracking and positions the beam director. The U.S. military has developed an Active Denial System that aims microwaves at people to cause pain without injury. The system consists of several modules: an infrared detection system to detect the missile's launch; the Tracking Illumination Laser (TILL); the Beacon Illuminator Laser (BILL); and the Chemical Oxygen Iodine Laser (COIL). The U.S. military has developed a directed energy technology that shoots beams of a slightly longer wavelength in a focused area over distances up to a mile. Once tracked by the TILL, the BILL measures the atmospheric distortion between the COIL and the missile. Washington, DC 20319-5066. This laser would be megawatt class and have a range of hundreds of miles. 4 Slab Lasers, RP Photonics Encyclopedia website, available at . Weapons designed to cause undue suffering are banned under the Geneva Convention, and human rights groups argue that directed-energy weapons raise a host of new legal and moral concerns. 15-31. [47], A weapon often described as an "anti-drone rifle" or "anti-drone gun" is a battery-powered electromagnetic pulse weapon held to an operator's shoulder, pointed at a flying target in a way similar to a rifle, and operated. Depending on the particulars of the weapon, and how it is used, ERP levels can reach into the hundreds of gigawatts or higher. https://en.wikipedia.org/w/index.php?title=Directed-energy_weapon&oldid=1140806805. The power output necessary for a weapons-grade laser ranges from 10 kilowatts to 1 megawatt. . The skin of the missile heats up, melts, and deforms, and the target breaks up in midair. Some common bio-effects of non-lethal electromagnetic weapons include: Interference with breathing poses the most significant, potentially lethal results. Putting the proper protocols in place should mitigate these concerns. This laser uses rings of magnetically confined electrons whirling at the speed of light to produce laser beams that can be tuned up and down the electromagnetic spectrum from microwaves to ultraviolet light.[4]. The technology is maturing rapidly, threats are emerging which directed energy can almost uniquely address, and the warfighters are signaling their support. [10], Once tracked by the TILL, the BILL measures the atmospheric distortion between the COIL and the missile. In addition, controllers can vary the strength of the energy put on a target, unlike a bullet or exploding bomb, allowing for nonlethal uses. High-power microwave (HPM) weapons work by producing either beams or short bursts of high-frequency radio energy. 1 Department of Defense Joint Publication 3-13.1, Electronic Warfare (Washington, DC: Department of Defense, 2012). This sound, magnified by the dish reflectors, caused vertigo and nausea at 200400 meters (220440yd) by vibrating the middle ear bones and shaking the cochlear fluid within the inner ear. The humanitarian community is also concerned about the long-term biological effects of DEWs (microwaves in particular) and their possible use against civilian targets.[25]. The number of "shots" a laser weapon can produce is limited only by its power supply. As with all new weapons, the DOD General Counsel reviews each DEW for compliance with international and U.S. laws before the Pentagon is allowed to field it. '[67] The British Ministry of Defence denied the existence of such a device. The Defense Department needs to establish clear guidelines for using the technology. They are not "weapons of mass destruction," but they have the potential to . The Air Force also recently demonstrated the ability of an HPM weapon to bring down multiple drones in testing at White Sands Missile Range in New Mexico, according to a recent Military.com article: After decades of research and investment, we believe these advanced directed-energy applications will soon be ready for the battlefield to help protect people, assets and infrastructure. Thomas Bussing, Raytheon Advanced Missile Systems vice president, said in a news release accompanying the announcement. Light is, for practical purposes, unaffected by, Lasers travel at light-speed and have long range, making them suitable for use in. A microwave weapon can achieve this result by causing malfunctions within certain relay and processing circuits within the enemy target system. When these waves interact with a person, they pass through the skin and transfer energy to the water that lies just under the surface. , 2019, available at . Think of the difference between a laser pointer and a flashlight. In addition, a technique known as adaptive optics has been developed for many years. Adversaries are not waiting to develop directed energy weapons. Microwave weapons can be aimed at computers, electronical devices and persons. . Are these weapons still science fiction, lab experiments, or are they real? At some point in the future, entire military units may be armed with only DEWs. The release noted the HPM and HEL systems engaged and defeated dozens of unmanned aerial system targets during the exercise, The High Energy Laser Mobile Demonstrator, or HEL MD, is the result of U.S. Army Space and Missile Defense Command research.
