Starstreak is a British short-range surface to air missile that can be used as a man-portable air-defence system (MANPADS) or in heavier systems, manufactured by Thales Air Defence (formerly Shorts Missile Systems), in Belfast, Northern Ireland. It is also known as Starstreak HVM (High Velocity Missile). After launch, the missile accelerates to more than Mach 4, making it the fastest short-range surface-to-air missile in existence. It then launches three laser beam-riding submunitions, increasing the likelihood of a successful hit on the target. Starstreak has been in service with the British Army since 1997. In 2012 Thales relaunched the system as ForceSHIELD. Development Development on the missile began in the early 1980s after an evaluation of missile and gun options to increase air defence capabilities showed that a high-velocity missile system would best meet the needs and could also replace existing shoulder-launched missiles. A General Staff Requirement (GSR3979) was drawn up with the requirements of the system, specifying the requirement of three launch platforms for the missile: A self-propelled launcher. A three-round lightweight launcher. A man-portable launcher. In 1984, the British Ministry of Defence awarded development contracts to British Aerospace (BAe) and Shorts Missile Systems; the BAe missile was known as Thunderbolt HVM. Shorts won the competition and were awarded £356 million. Further development and a production contract materialized in November 1986, and the missile was officially accepted into service in September 1997. The missile was intended to replace the Javelin surface-to-air missile in British service. The LML and shoulder-launched versions have been in use since 2000. In July 2001, Thales received a contract for a successor identification friend or foe system for Starstreak. In mid-2007, Thales UK in Northern Ireland revealed that it had developed Starstreak II, a much improved successor to the Starstreak missile. Some of the advantages of the new version are increased range of , improved lethality, an improved targeting system, and much higher operating ceiling. In 2011, when it won a contract for the Lightweight Multirole Missile (LMM), Thales announced it had agreed with the Ministry of Defence to "re-role previously contracted budgets to facilitate the full-scale development, series production and introduction of the LMM." The contract affected is speculated to have been Starstreak. Description When used in the light or MANPADS role, the Starstreak missile is transported in a sealed launch tube. This tube is attached to an aiming unit for firing. The operator tracks
