The FIM-92 Stinger is a combat-proven, lightweight, impact-penetration, supersonic, fire-and-forget, multi-platform, air-to-air and surface-to-air missile developed to counter low level flying threats such as aircraft, helicopters, UAVs and cruise missiles. The Stinger missiles is man-portable and shoulder-fired and has been installed on ground vehicles to provide short-range/close-in air defense capability to ground military units. It has also been installed on helicopters for self-defense purposes.

The Stinger-RMP (Reprogrammable Microprocessor) was deployed in 1989 correcting known operational deficiencies. The Stinger-RMP is a reprogrammable missile meaning that no hardware changes are required to change missile's software. The Stinger-RMP adds an improved IR-UV (Infrared and Ultraviolet) seeker, Identification Friend or Foe (IFF), improved range, improved maneuverability and best performance in IR countermeasures (IRCM) environments to the baseline Stinger missile.

The changes applied to the Singer-RMP missile were the result of operational deficiencies assessments and the need to counter emerging sophisticated air threats. Raytheon and the US Army are carrying out a Preplanned Product Improvement (P3I) program to add new hardware to the Stinger missile improving its military capabilities.
