Storm Shadow is an Anglo-French air-launched cruise missile, manufactured by MBDA and used by France Italy and the UK. Storm Shadow is the British name for the weapon; in French service it is called SCALP EG (Emploi Général, meaning General Purpose). The missile is based on the earlier MBDA Apache anti-runway missile, and differs in that it carries a warhead, rather than submunitions.
the missile is designed to be carried by the Tornado, Eurofighter Typhoon, Mirage 2000 and Rafale, the missiles is also another british product that the Spams love, so when it enters service the The F-35 Lightning II will also carry the missile.
The BROACH warhead features an initial penetrating charge to clear soil or enter a bunker, then a variable delay fuse to control detonation of the main warhead. Intended targets are command, control and communications, airfields, ports, AMS/ammunition storage, ships/submarines in port, and bridges.
It is a fire and forget missile, programmed before launch. Once launched, the missile cannot be controlled, its target information changed or be self-destroyed. Mission planners programme the missile with the target air defences and target. The missile follows a path semi-autonomously, on a low flight path guided by GPS and terrain matching to the area of the target. Once close to the target, the missile pulls up, climbing to an altitude intended to achieve the best probability of target identification and penetration. During the climb, the nose cone is jettisoned to allow a high resolution infrared camera to observe the target area (the climb enlarges the field of vision). The missile then tries to locate its target based upon its targeting information. If it can not, and there is a high risk of collateral damage, it will fly to a crash point instead of risking inaccuracy.
MBDA is developing a longer range sea-launched variant, to be called SCALP Naval, to be launched from surface vessels and submarines using the A70 version of the SYLVER launcher on the former. To provide a comparable range to the Tomahawk missile the range of the SCALP Naval would have to be significantly larger than the Storm Shadow.
The Storm Shadow was suggested as part of the RAF]]'s Future Offensive Air System, possibly using a non-penetrating aircraft (e.g. C-130J or A400M) deploying large numbers of the missile. The FOAS study was cancelled in 2005, although the Storm Shadow may still be included in future studies.
