The Stinger-Reprogrammable Microprocessor, or RMP, missile has a greater than 90 percent success rate in reliability and training tests. Its supersonic speed, agility and a highly accurate guidance and control system give the weapon an operational edge against cruise missiles and all classes of aircraft. The system is also used on Apache helicopters for air-to-air engagements.
In 2019, the U.S. Army began retrofitting its Stinger missiles with proximity fuzes, which allow missiles to destroy unmanned airborne systems with direct hits or by detonating near them. A pair of Stinger missiles intercepted two drones using proximity fuzes during an Army test in 2017.
The modified missile offers ground troops better defense against small, agile threats.
