El Departamento de Defensa de EUA ha establecido \u00a0que las Armas de Energ\u00eda Directa (DEW) constituyen una importante prioridad en el sistema de defensa de ese pa\u00eds. En el marco de los proyectos que se llevan adelante, el US ARMY a ensayado junto con el contratista LOCKHEED MARTIN, un Laser de alta potencia de 60Kw que constituye un verdadero record en el empleo de estas armas desde plataformas terrestres m\u00f3viles. Anteriormente se hab\u00eda ensayado con \u00e9xito un Laser de 10Kw desde un Veh\u00edculo a ruedas. La cantidad de proyectos de \u00e9ste tipo y los presupuestos asignados, ponen en evidencia la creciente aceptaci\u00f3n de las DEW, como una alternativa eficiente y de bajo costo para neutralizar amenazas a\u00e9reas tales como UAV\u00b4s, \u00a0cohetes y misiles.<\/p>\n
HUNTSVILLE, Ala.\u00a0\u2014\u00a0The U.S. Army is taking delivery of a 60 kilowatt-class laser from Lockheed Martin as the company wraps up demonstrations of the capability.<\/p>\n
\u201cIn testing earlier this month, the Lockheed Martin laser produced a single beam of 58kW, representing a world record for a laser of this type,\u201d the company said in a statement Thursday.<\/p>\n
Now that the laser is in Army hands, Radiance Technologies, which has been working on Boeing’s High Energy Laser Mobile Demonstrator (HEL MD) program since 2012 will conduct laboratory testing of the new laser.<\/p>\n
Once the laser is integrated onto the Army’s Heavy Expanded Mobility Tactical Truck, or HEMTT, that becomes the High Energy Laser Mobile Test Truck. Radiance will coordinate all testing of the laser against targets.<\/p>\n
The HEMTT is the largest vehicle in the Army inventory and previously a 10-kW laser was tested on the platform.<\/p>\n
The new laser is based on a design developed under the Department of Defense\u2019s Robust Electric Laser Initiative Program, as well as through investments into the 60 kW-class system by the company and the Army.<\/p>\n
The Pentagon has made directed energy an important priority because military officials believe ultimately employing lasers will dramatically decrease the cost of firing shots. Missiles, rockets, artillery and mortars would ultimately cost far more than shooting with a laser, and with the proper power source, laser weapons would never run out of ammunition.<\/p>\n
The delivery of the more powerful laser to the Army marks another important milestone in developing directed energy to be used as laser weapons on a variety of platforms.<\/p>\n
The 10-kW specialized commercial-off-the-shelf welding laser on a HEMTT was tested between 2010 and 2014 in the High Energy Laser Mobile Demonstrator program and shot down targets in flight, to include class 2 unmanned aircraft systems and 60mm mortars at White Sands Missile Range, New Mexico.<\/p>\n
The less powerful laser was also tested at Fort Sill, Oklahoma, during a maneuver fires integration experiment last spring where the primary targets were class 1 quadcopter UAS as well as ground targets like simulated ground stations and ammunition points.<\/p>\n
In 2015, the company used a 30-kW fiber laser weapon, known as ATHENA, to disable a truck from a mile away.<\/p>\n
Lockheed is preparing to ship the 60-kW laser to the U.S. Army Space and Missile Defense Command and Army Forces Strategic Command in Huntsville, Ala.<\/p>\n
The more powerful laser brings together individual lasers \u201cgenerated through fiber optics, to generate a single, intense laser beam,\u201d Lockheed explained, which allows for it to be scaled up in power by adding more fiber laser subunits.<\/p>\n
\u201cWe have shown that a powerful directed energy laser is now sufficiently light-weight, low volume and reliable enough to be deployed on tactical vehicles for defensive applications on land, at sea and in the air,\u201d Robert Afzal, a senior fellow for Lockheed\u2019s Laser and Sensor Systems business, said.<\/p>\n
The laser system has \u201cproved to be highly efficient in testing,\u201d the company stated, \u201ccapable of translating more than 43 percent of the electricity that powered it directly into the actual laser beam it emitted.”<\/p>\n
