Stormer HVM is a British self-propelled Starstreak High Velocity Missile air-defense system mounted on the tracked Alvis Stormer vehicle. It combines a protected CVR(T)-derived carrier, passive target-alerting equipment, and a roof launcher with eight ready Starstreak missiles for close air defense against low-flying aircraft, helicopters, and UAVs. The United Kingdom announced Stormer transfers to Ukraine in April 2022, later stated that six Stormer vehicles with Starstreak launchers had been supplied, and Ukrainian reporting placed the systems on the frontline by late July 2022.
The United Kingdom announced Stormer armoured vehicles fitted with anti-air missile launchers for Ukraine on 25 April 2022 and later stated that six Stormer vehicles with Starstreak launchers had been supplied; Ukrainian frontline reporting documented Stormer HVM systems in Armed Forces of Ukraine service.
Role detailsStormer HVM combines a tracked Alvis Stormer vehicle with the Starstreak High Velocity Missile launcher and passive target-cueing equipment. British Army material identifies the self-propelled HVM fit as eight ready Starstreak missiles on the vehicle and twelve additional missiles carried, while other secondary references give a lower reload count. This entry uses the British Army figure in specifications and treats the lower count as a source discrepancy rather than a separate configuration.
A roof-mounted Air Defence Alerting Device uses infrared scanning and processing to detect and prioritise targets, then slews the weapon sight toward the target.
Starstreak is a laser beam-riding HVM family missile with three dart-type projectiles and a speed above Mach 3 in British Army descriptions.
The Stormer vehicles supplied to Ukraine were framed by the UK as short-range anti-air capability, with Ukrainian reporting later describing frontline air-defense use against Russian UAVs.

Stormer HVM is the self-propelled member of the Starstreak/HVM family. The same missile family also appears in lightweight multiple-launcher and shoulder-fired configurations, while the Stormer chassis was adapted into other support and specialist variants.
