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, it is 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,[4][3] making it the fastest short-range surface-to-air missile in existence.[5] 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.[5]
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)[6] was drawn up with the requirements of the system, specifying the requirement of three launch platforms for the missile:
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.[6] The LML and shoulder-launched versions have been in use since 2000.[6]
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 7 km (4.3 mi), improved lethality,[2][3] an improved targeting system, and much higher operating ceiling,[7] up to 5 km (16,000 ft).[8]
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.[9]
Description
A Starstreak, just after being launched from an AN/TWQ-1 Avenger mobile, short-range air-defence platform
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 the target using the aiming unit's optically stabilized sight. The process of tracking the target allows the aiming unit to compute the right trajectory to bring the missile together with the target. The operator can indicate wind direction to the unit and, in the case of a long-range target, provide superelevation. When the initial tracking is complete, the operator fires the missile by pressing a button.[6]
The missile then fires the first-stage rocket motor; this launches the missile from the tube but burns out before leaving the tube to protect the operator. Four metres (thirteen feet) away from the operator, when the missile is at a safe distance, the second stage fires. This rapidly accelerates the missile to a burn-out velocity exceeding Mach 4. As the second stage burns out, three dart sub-munitions are released.
The dart housing is made from a tungstenalloy. The darts are each 396 millimetres (15.6 in) long, 22 millimetres (0.87 in) in diameter, and about 900 grams (32 oz) in mass. Around half the weight of each dart - approximately 450 g (16 oz) - is its explosive charge, detonated by a delayed-action, impact-activated fuse.[6] Each dart consists of a rotating fore-body, with two canard fins, attached to a non-rotating rear assembly with four fins. The rear assembly of each dart also houses the guidance electronics including a rearwards facing sensor.
The darts do not home in on laser energy reflected from the target; instead, the aiming unit projects two laser beams which paint a two-dimensional matrix upon the target. The lasers are modulated, and by examining these modulations the sub-munitions sensor can determine the dart's location within the matrix. The dart is then steered to keep it in the centre of the matrix. The sub-munitions steer by briefly decelerating the rotating fore-body with a clutch. The front wings then steer the missile in the appropriate direction. The three sub-munitions fly in a formation about 1.5 metres (4.9 ft) in radius, and have enough kinetic energy to manoeuvre to meet a target evading at 9g at 7,000 metres (23,000 ft).[6]
Earlier laser guidance systems used a single beam that had to be kept on the target at all times, the missile homing in on laser energy reflected off the target; if it moved off the target, the reflection would end and guidance would be lost until the target was regained. This problem could be reduced by making the laser's beam wider, but at the cost of reduced accuracy and reflected energy. Starstreak's system allows for the beam area to be much larger than the target while retaining pinpoint accuracy.
On impact with the target a delayed-action fuse is triggered, allowing the projectile to penetrate the target before the explosive warheaddetonates. The tungsten housing is designed to fragment and maximise damage inside the target.[6]

The missile was brought into service with 12 Regiment Royal Artillery and 47 Regiment Royal Artillery in 1997 as part of the High Velocity Missile (HVM) system equipped with both the Air Defence Acquisition Device (ADAD) and a ×60 thermal sight. Each regiment was equipped with 108 HVM self-propelled armoured launchers mounted on the Stormer tracked chassis capable of holding eight missiles ready to fire and a further eight reloads (the original capacity of twelve was reduced during a revision). The launchers could originally run on batteries for extended periods to minimise their signature, but significant upgrades dramatically increased the system's power requirements. A light-role variant known as HVM Lightweight Multi Launch (LML), capable of holding three ready-to-fire missiles, was also brought into service with the Air Defence Troop Royal Marines and a Royal Artillery Air Assault Battery attached to 16 Air Assault Brigade. The systems' armoured variant, the HVM Self Propelled (Stormer), saw service during the Second Gulf War but did not fire. The British Army currently uses the A5 fifth-generation missile, significantly improved from the original missile. The HVM SP and LML variants now carry a mix of both Starstreak A5 and Lightweight Multirole Missiles.
In 2012, the Ministry of Defence announced that it would be placing HVM LML light role detachments equipped with Starstreak A4 missiles on top of several blocks of flats in London prior to the 2012 London Olympics. The Ministry claimed that the area was the only suitable location for an air defence detachment of the type. Some residents were upset and uncertain of the necessity of the detachment.[10][11] In 2013, the British MOD ordered 200 more Starstreak missiles.[12]
On 16 March 2022, Defence SecretaryBen Wallace announced that the UK would supply Ukraine with Starstreak missiles to help prevent Russian air supremacy following the 2022 Russian invasion of Ukraine.[13] British soldiers trained Ukrainian forces to use the system.[14] HVM SPs were also deployed to Poland as an interim measure until the arrival of Sky Sabre.[15] In April 2022, Starstreak missiles were in use by Ukrainian soldiers,[16] and it was reported that Ukrainian forces appeared to have successfully used the system to shoot down a Russian Mi-28N attack helicopter.[17][18] The missile, according to footage released by the UK MOD, hit with all three projectiles, splitting the helicopter in half.[18]
In April there were claims that the UK would be providing Alvis Stormer vehicles armed with Starstreak. There are reports the Stormer HVM is being supplied to Ukraine.[19] The system has been used to shoot down a drone during April as well. [20]
ATASK (Air To Air Starstreak): Fired from a helicopter. This was developed in combination with McDonnell-Douglas and Lockheed-Martin electronics between 1995 and 1998 specifically for use with the AH-64 Apache. It has yet to enter service.[6]
LML: Fired from a Lightweight Multiple Launcher (LML) that holds three missiles ready for firing and can be used as either a stationary launch unit or mounted on a light vehicle such as a Land Rover or HMMWV (Humvee). The LML originated in a proposal under the Army Suggestions Scheme for the Javelin system.[6]
Seastreak: Two versions of a naval mounting have been demonstrated—a one-man mount similar to the LML but carrying a total of six missiles, and a close in weapon system mounting holding 24 missiles.
Self-propelled (SP) HVM: Carried on an Alvis Stormer AFV with a roof-mounted eight-round launcher with internal storage for a further 8 missiles.[6] This is the most common variant.
Starstreak Avenger: Built to a U.S. Army requirement in the early 1990s, this system integrated the Starstreak missile on the Boeing Avenger vehicle, replacing 1 pod of Stinger missiles with 1 pod of 4 Starstreak and modifying the fire control system accordingly.
Starstreak Mark II: Upgrade to the Starstreak.
THOR/Multi Mission System (MMS): A four-missile turret mounted on a Pinzgauer (6×6) cross-country chassis,[21] launched by Thales UK in 2005.[22]
