The death ray or death beam was a theoretical particle beam or electromagnetic weapon of the 1920s through the 1930s - hypothetical beam weapon, able to hit the target at a distance by means of directional emission.
At the beginning of XX century, the idea of XX death ray was very popular. Nikola Tesla claimed to have invented a death ray which he called teleforce in the 1930s. Nikola Tesla (10 July 1856 – 7 January 1943) was a Serbian-American inventor, electrical engineer, mechanical engineer, physicist, and futurist best known for his contributions to the design of the modern alternating current (AC) electrical supply system. In theory, the device can generate intensely directed beam energy, which could be used for the destruction of enemy aircrafts, army and other things. However, the "death ray" and has not been released Tesla, though He tried to sell it different military units.
American corporation Boeing with USAF in Kirtland Air Base (New Mexico) has successfully tested a laser weapon on 2 September 2009. As a goal was selected a motionless car on the territory of rocket polygon White Sands. The laser, installed on the aircraft C-130H, have guided on the object, and then destroyed his accurate shot.
Earlier USAF tested of such weapon. In August 2009, under the experiment, laser complex, installed on the platform of the liner "Boeing 747-400", intercepted, tracked and destroyed the training missile.
System, named Boeing YAL-1 Airborne Laser (ABL), is a combination of oxygen-iodide chemical laser capacity of near megawatt and two kilowatt lasers, designed for backlight launch missile. The complex is designed for destruction tactical warheads, different from the strategic abbreviated radius of action and lower speed flight.
After the start such a missile system will highlight it usual lasers, and after, making amendments on the rate of flight, atmospheric phenomena and strength missiles, destroy megawatt laser, located in the tail of the aircraft and aimed at the target with a system of mirrors, fixed in front. According to calculations constructors, range weapons should amount 300 - 600 kilometers.
11 February 2010, high power laser, placed on airborne (Boeing-747-400F), destroyed a ballistic missile in the boost part of the trajectory in during the test on the polygon in California.
