The US Army tested Raytheon-made Stinger anti-air missiles equipped with new proximity fuzes for the first time, successfully intercepting two small unmanned aerial vehicles. The company's Land Warfare Systems Vice President Kim Ernzen said Stingers were generally used against low-altitude larger targets such as helicopters and fixed-winged aircraft, however the new proximity fuze enables engaging smaller targets such as small UAVs. The Stinger weapon system is a man-portable, shoulder-fired guided missile system employing “fire and forget” principle.
