In three weeks of testing at New Mexico's White Sands Missile Range, the US Army recently reported they'd successfully engaged over 90 mortars and drones with--a giant laser mounted on top of a truck. Using radar to locate and engage its quarry, the 10 kW Boieng-built laser--which is roughly equivalent to 10,000 light bulbs focused into a coin-sized beam--acquires its target and rapidly heats it until the weapon explodes in midair.
