We proved that the technology could be effective, but its size, weight, and power (SWaP) requirements made the laser weapons impracticable to field. 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. [16] When the microwave energy encounters unshielded wires or electronic components, it induces a current in them, which causes the equipment to malfunction. 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. The Sodium Guidestar at the Air Force Research Laboratory Directed Energy Directorate's Starfire Optical Range. First, the choice of a lasers wavelength can help to mitigate the affect because different laser wavelengths perform much better in the atmosphere than others. Millimeter waveband energy can penetrate human skin to a very shallow depth, heating the tissue below. Other members of a crowd are unaffected, except by panic when they see people fainting, being sick, or running from the scene with their hands over their ears. 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. 4 Slab Lasers, RP Photonics Encyclopedia website, available at . A DE weapon is a system using DE primarily as a direct means to disable, damage or destroy adversary equipment, facilities, and personnel. 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. They are not the answer to all the challenges, and will not replace kinetic weapons, but they are an essential adjunct to countering specific threats and providing dominance in land, air, sea, and space. Particle beams as beam weapons are theoretically possible, but practical weapons have not been demonstrated yet. [74] Some of the victims of this method suffered from suspicious cases of cancer and have claimed that they had also been targeted with directed X-rays. For continuous wave systems, which use high average power to effect targets, levels are typically from 50 to 100s of kilowatts up to several megawatts of power. They can not only achieve these speeds but can maneuver at them as well including varying trajectories, headings and altitudes. For example, a Navy ship-to-air laser will have different requirements than an Air Force air-to-air system, which will have different requirements than a space-based missile defense system and therefore different technological considerations. Particle-beam weapons can use charged or neutral particles, and can be either endoatmospheric or exoatmospheric. Laser weapons potentially eliminate many logistical problems in terms of ammunition supply, as long as there is enough energy to power them. In fact, the megawatt-class Airborne Laser developed in the late 1990s and early 2000s required an entire 747 aircraft to hold the equipment. HPM weapon technology is based on the same technology as radar devices, which already have a long history of research and development. While the development costs of directed energy systems can be high, there are several factors in play which can reduce these costs or at least provide better return on the investment over the life cycle. True support for a program is often best measured by the resources that an organization is willing to devote to it. While they are both part of the electromagnetic spectrum, laser and microwave weapons operate very differently and have very different effects. Furthermore, the power of lasers and microwave weapons has decreased, allowing for nonlethal uses. (Courtesy photo), The High Energy Laser Mobile Demonstrator, or HEL MD, is the result of U.S. Army Space and Missile Defense Command research (U.S. Army), The premier professional military and academic publishing house. Space-based high energy lasers could be brought to bear especially in the boost/ascent phase of boost glide hypersonic missiles where a high-energy laser could destroy the vehicle early in its trajectory. 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]. [71] The negative effects of the radiation poisoning and cancer would extend past the period of incarceration. A DE weapon is a system using DE primarily as a direct means to This information is then transferred to an optical tracking system, which refines the target tracking and positions the beam director. While directed-energy research is advancing, inadequate funding is hindering more rapid development and deployment of these technologies. [2]David E. Fisher, A Race on the Edge of Time: Radar-The Decisive Weapon of WWII (New York: McGraw-Hill, 1988), pp. The pain forces the person to flee the area. 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. Neither should we. National Defense University Space-based lasers would have a profound impact on the U.S. ability to defend and if necessary, fight in space. The Defense Department needs to establish clear guidelines for using the technology. [1] They may begin to appear on the battlefield within the next decade, bringing a revolution in weapons and how war is waged. [61][62], Stories in the 1930s and World War Two gave rise to the idea of an "engine-stopping ray". 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. PRISM Vol. But there is a rule of thumb that states that an interceptor needs to be capable of three times the speed of the target it is defending against to be able to maneuver to destroy it. The United States cannot allow itself to fall behind in yet another area of warfighting as has happened in hypersonics. The Air Force Research Lab's Propulsion Directorate has studied using generators that use high-temperature superconducting wire and high-voltage capacitors. Weapons that go beyond non-lethal intentions and cause 'superfluous injury or unnecessary suffering' may also violate the Protocol I to the Geneva Conventions of 1977."[87]. A possible future development is the electrolaser. Microwave weapons can be aimed at computers, electronical devices and persons. [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. 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. and DEWs use the electromagnetic spectrum (light and radio energy) to attack pinpoint targets at the speed of light. Developing hypersonic interceptors will also be an option in the U.S. defense architecture. The article states: 'The squawk box is highly directional which gives it its appeal. Lieutenant General Henry Trey Obering, III, USAF (Ret. [20], 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. However, no military has yet openly deployed HPM weapons. Boeing has received a C-130H transport aircraft from the Air Force and is modifying it for installation of the laser system. For example, the static and distortion that high voltage power lines have on a car radio causes no lasting damage to the radio after the car leaves the area. Directed energy weapons are among the high-tech arms of the century. HPM weapons have also been considered for use as nonlethal "heat ray" systems for crowd control. Electronic devices can be shielded by putting conductive metal cages around them; however, enough microwave energy may still get through the shielding to damage the device. 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. However, British scientists calculated that the electronic systems of the time could not generate the power necessary for a "death ray," and research was redirected into early radar detection systems. This information is then transferred to an optical tracking system, which refines the target tracking and positions the beam director. 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. Panel discussions on the role of high-power lasers in SDI took place at various laser conferences, during the 1980s, with the participation of noted physicists including Edward Teller.[76][77]. As another example, high energy lasers could be used to protect forward-deployed troops and bases from attacks by swarms of unmanned aircraft carrying explosive devices. Examples of this cited earlier included the Airborne Laser, the Navys LaWS program, and others. The electrical shock is enough to stun personnel, detonate improvised explosive devices, or destroy electronic equipment. The two U.S. laser weapons systems closest to actual deployment are the Tactical High-Energy Laser (THEL) and the Airborne Laser (ABL). 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. - The Navy continues to learn more about a pair of directed energy weapons, as the service installs the fourth and fifth dazzler system this year and begins land-based testing of . In addition to the nuclear ballistic missile threat posed by North Korea, which can be defended by U.S. missile defense systems, there is a North Korean threat which cannot be defended against today. from PrayingMedic: Q NOVEMBER-DECEMBER 2022 VIDEO: [41] Vigilant Eagle was not mentioned on Raytheon's Web site in 2022. 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. 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 .
