A related project is the Advanced Tactical Laser (ATL) system, which uses a less powerful version of the ABL's COIL laser, instead of missiles, to attack ground targets. While DEWs are not the solution to all combat situations, these technologies would provide the U.S. military with additional flexibility in tailoring its response to different types of threats. While centuries of technological advances have improved the power of these materials, the basic operating principle of chemical-powered weapons ultimately remains the same. 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. However, a variety of optical methods can be used to correct for blooming. 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). Development of the THEL began in 1996 as a joint program between the United States and Israel to develop a laser system capable of shooting down Katyusha rockets, artillery, and mortar shells. 79, No. Directed energy weapons, such as lasers and microwaves, had enjoyed an exotic aura. 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. This article will examine answers to these questions. The laser light is coherent in a single color, and the flashlight is broad-spectrum light. While some uses may be illegal (e.g., targeting an unarmed civilian who in no way poses a threat), other uses are just as assuredly legal and legitimate. During the Iraq War, electromagnetic weapons, including high power microwaves, were used by the U.S. military to disrupt and destroy Iraqi electronic systems and may have been used for crowd control. They are real and are maturing rapidly. They seemed to have arisen from the testing of the television transmitter in Feldberg, Germany. The full system will be fitted to the aircraft by 2007 and test-fired against ground targets. The number of "shots" a laser weapon can produce is limited only by its power supply. On August 24, 2004, the Tactical High Energy Laser (THEL) system destroyed a salvo of mortar rounds in midair during a test. These waves penetrate only a few millimeters into the skin and cause the sensation of heat. The Beacon Illuminator Laser system, which measures and corrects for atmospheric distortion, has also been shipped to Boeing for testing. can affect a lasers performance but there are ways to address these phenomena. The virus that causes COVID-19 most likely leaked from a Chinese laboratory, according to a classified report based on new intelligence and recently sent to the White House and key members . Improvements in energy-generating systems may also make particle-beam weapons feasible. In 1995, the Chinese military marketed the ZM-87 laser interference device, a tripod-mounted battlefield laser dazzler designed to blind enemy soldiers and optics temporarily. However, as with the development of any unprecedented military capability, there are risks, challenges and limitations involving their cost, schedule and performance. This makes targeting and tracking easier as well. However, risks, challenges and limitations remain. [65], The Central Intelligence Agency informed Secretary Henry Kissinger that it had twelve reports of Soviet forces using laser weapons against Chinese forces during the 1969 Sino-Soviet border clashes, though William Colby doubted that they had actually been employed. Additional information on How Lasers Work, is available on the Lawrence Livermore National Lab website, . 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. Like lasers, HPM weapons can operate in a pulsed or continuous manner and are classified using peak or average power respectively. Adversaries are not waiting to develop directed energy weapons. HPM lethality can be affected by atmospheric conditions as well, but to a much lesser degree than high-energy laser (HEL) weapons. Examples include damaging individual components, circuit cards, or the mother boards in a desktop computer. 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. In addition, a technique known as adaptive optics has been developed for many years. 7 David M. Sowders et al., High Power Microwave (HPM) and Ultrawideband (UWB): A Primer on High Power RF, PL-TR-95-1111, Special Report, Phillips Laboratory, March 1996, 76. The short, intense bursts of energy produced by HPM devices damage equipment without injuring personnel. Andrew Gudgel. 3. However, current research focuses on using them as a means of nonlethal area defense and as anti-electronic weapons rather than as "death rays.". Paired with a microwave generator, an EPFCG could produce an ultrashort, intense microwave burst. Directed energy weapon could be responsible for auditory hallucinations, brain injuries. This produces a burning pain without actually damaging the tissue. It stated that it did have, however, an 'ultra-loud public address system which [] could be "used for verbal communication over two miles, or put out a sustained or modulated sound blanket to make conversation, and thus crowd organisation, impossible. However, Boeing has been somewhat successful with the Boeing YAL-1 and Boeing NC-135, the first of which destroyed two missiles in February 2010. The Symptoms of Being Attacked by Directed Energy Weapons DEW symptoms: Causes headaches, intense psychological and physiological stress in that you can feel all your insides. In the next several years, the U.S. Army, Navy and Air Force all plan to develop and field these weapons at an increasing pace. They can destroy, degrade or blind many other systems that contain sensors and electronics. The destructive power of directed energy weapons (their lethality) derives from the amount of energy transferred to the target over time. The Active Denial System (ADS) is a nonlethal anti-personnel DEW that uses millimeter-wavelength beams to create a painful sensation in an individual without causing actual injury. The ABL is a system that uses a megawatt chemical laser mounted on a modified Boeing 747 to shoot down theater ballistic missiles. In fact, the megawatt-class Airborne Laser developed in the late 1990s and early 2000s required an entire 747 aircraft to hold the equipment. At the speeds that these hypersonic missiles fly, they have vulnerabilities which could be exploited by directed energy weapons. So hypersonic kinetic interceptors would have to be capable of achieving speeds of Mach 15 and higher. Vection and motion sickness can also occur. The laser is being built and will be tested in mid-2006. The Sodium Guidestar at the Air Force Research Laboratory Directed Energy Directorate's Starfire Optical Range. Boost glide weapons are launched atop ballistic missiles then released to glide to the target. 019, available at < https://www.defense.gov/Portals/1/Interactive/2018/11-2019-Missile-Defense-Review/The%202019%20MDR_Executive%20Summary.pdf>. When the LaWS was being integrated onto the ship, the designers and developers envisioned that it would be used several hours a day. The Sodium Guidestar at the Air Force Research Laboratory Directed Energy Directorate's Starfire Optical Range. In recent years the U.S. Navy deployed a 30kW class solid state laser weapon system (LaWS) prototype on the Afloat Forward Staging Base, USS Ponce. 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]. This makes targeting and tracking easier as well. The two U.S. laser weapons systems closest to actual deployment are the Tactical High-Energy Laser (THEL) and the Airborne Laser (ABL). [49] It is relatively close to deployment. Army Successfully Demos Laser Weapon Stryker in Germany, DefenseNews.com, March 21, 2018, available at < https://www.defensenews.com/land/2018/03/21/us-army-successfully-demos-laser-weapon-on-stryker-in-europe/>. Because of its coherence, laser light can stay concentrated for very long distanceseven thousands of miles into space. They have strong physical and psychological effects and can be used for military and terrorist activities. Lasers are becoming smaller and more powerful. 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. Similar in principle to the microwave oven, the weapons produce energies in the megawatt range. This plan includes a program which aims to test high energy lasers on aircraft against surface to air and air to air missile threats. The system consists of a missile-detecting and tracking subsystem (MDT), a command and control system, and a scanning array. European Parliament For example, a recent test of a solid-state laser by Northrop Grumman produced a continuous 27-kilowatt beam that lasted just under six minutes.[23]. Washington, DC 20319-5066. 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. [16]U.S. Air Force Research Laboratory, "High-Power Microwaves," fact sheet, September 2002, at http://www.de.afrl.af.mil/Factsheets/HPM.swf (March 15, 2006). [12] A complete prototype ABL weapons system will be assembled in 2006. This concentrated energy can have effects across the entire spectrum from non-lethal to lethal. Thermal blooming occurs in both charged and neutral particle beams, and occurs when particles bump into one another under the effects of thermal vibration, or bump into air molecules. There is no injury to the target individual. [citation needed]. For high energy lasers, lethality depends on the power output of the laser, the purity and concentration of the light (beam quality), the target range, the ability to keep the laser on the target aimpoint (jitter control and tracking), and the atmospheric environment the laser traverses to the target. getty. 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. Similar in principle to the microwave oven, the weapons produce energies in the megawatt range. 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]. One of the most promising laser devices is the free-electron laser. Modern battlefield weapons are the descendents of muskets and cannon. [45] The energy spikes are tailored to enter missiles through antennae or sensor apertures where they can fool guidance systems, scramble computer memories or even burn out sensitive electronic components. Depending on the type of laser, this means that the weapon can have an almost "endless magazine" of laser bursts. How can they be used and how disruptive can they be? Conceptual MindWorks in San Antonio, TX received a $7 million cost-plus fixed-fee contract to provide for research support around emerging directed energy weapons (including non-lethal weapons) and their effects on humans.Work will be conducted in cooperation with the Air Force Research Laboratory, Human Effectiveness Directorate (AFRL/HEDR), Directed Energy Bio-effects Division, Radio . [46] Potentially lethal effects are produced only inside 100 meters range, and disruptive effects at distances on the order of one kilometer. A14.5 kHz E V2K 28-Dec-8927-Oct-92Oliver M. LoweryOliver M. LoweryPresents subliminal auditory information to the human via remotely applied waves US 5356368 A4-212 Hz MK 1-Mar-9118-Oct-94Robert A. MonroeInterstate Industries Inc. (dba Monroe Products)Method of and apparatus for inducing . They are well-suited to defending against threats such as missiles and artillery shells, which DEWs can shoot down in mid-flight. Development of the THEL began in 1996 as a joint program between the United States and Israel to develop a laser system capable of shooting down Katyusha rockets, artillery, and mortar shells. This type of weapon shows great potential as a riot-control device or area-denial system. The kinetic energy imparted by a particle stream destroys the target by heating the target's atoms to the point that the material literally explodes. We proved that the technology could be effective, but its size, weight, and power (SWaP) requirements made the laser weapons impracticable to field. Current HPM research focuses on pulsed power devices, which create intense, ultrashort bursts of electrical energy and would be used to power the microwave generator of an HPM weapon. 15 Office of the Secretary of Defense, Missile Defense Review, January 2019, available at < https://www.defense.gov/Portals/1/Interactive/2018/11-2019-Missile-Defense-Review/The%202019%20MDR_Executive%20Summary.pdf>. It has been claimed that the USSR made use of the lasers at the Terra-3 site to target the Space Shuttle Challenger in 1984. Examples of this capability include signal overrides or insertion, power cycling (turning power on and off at irregular intervals) and causing the system to lock-up. These effects are not permanent because the target system will return to normal operation within a specified time, which obviously varies according to the weapon. [7]Bill Gertz, "N. Korea Fired Laser at Troops," The Washington Times, May 13, 2003, at http://newsmine.org/archive/war-on-terror/north-korea/nkorea-fired-laser-at-troops.txt (March 15, 2006). This technology delivers very high-frequency millimeter-wavelength electromagnetic rays that heat skin on contact, causing a painful burning sensation. In the 1951 science fiction film, The Day the Earth Stood Still, powerful ray guns are shown vaporizing rifles and even tanks. This In Focus discusses a selection of (Invented by Max Steenbeck at Siemens-Schuckert in the 1930s, these were later called Betatrons by the Americans.) Because they were invented several decades ago, lasers are the most mature of the DEW technologies. What are Directed Energy Weapons? [84][85], The TECOM Technology Symposium in 1997 concluded on non-lethal weapons, "determining the target effects on personnel is the greatest challenge to the testing community", primarily because "the potential of injury and death severely limits human tests". Funding has been cut to both of the programs. [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. The skin of the missile heats up, melts, and deforms, and the target breaks up in midair. Microwave electromagnetic weapons can also stun a victim.
