Storm Shadow is an
Anglo-
French air-launched
cruise missile, manufactured by
MBDA and used by France,
Italy, the United Kingdom and
Greece. 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.
Characteristics
The stealthy missile has a range in excess of , is powered by a turbojet at Mach 0.8 and can be carried by the
Tornado GR4, Italian
Tornado IDS,
Eurofighter Typhoon,
Dassault Mirage 2000 and
Dassault Rafale aircraft. The
F-35 Lightning II will also carry the missile once the aircraft enters service. 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. The missile weighs about has a maximum body diameter of and a wingspan of . Intended targets are command, control and communications; airfield facilities; port facilities; 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.
Close to the target, the missile
bunts, climbing to an altitude intended to achieve the best probability of target identification and penetration. During the bunt, the nose cone is jettisoned to allow a high resolution
infrared camera to observe the target area (the bunt 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.
History
thumb|left|Storm Shadow at the RAF Museum LondonBritish Aerospace and Matra were competing with
McDonnell Douglas,
Texas Instruments/
Short Brothers,
Hughes/
Smiths Industries,
Daimler-Benz Aerospace/
Bofors,
GEC-Marconi and
Rafael. The BAe/Matra Storm Shadow was selected on
25th June 1996. A development and production contract was signed on
1997-02-11, by which time Matra and BAe had completed the merger of their missile businesses to form
Matra BAe Dynamics. France ordered 500 SCALP missiles in January 1998.
The first successful fully-guided firing of the Storm Shadow/SCALP EG took place at the CEL Biscarosse range in France at the end of December 2000. The launching aircraft was a Mirage 2000N. The first British firing occurred on
2001-05-25 from a Tornado flying from
BAE Warton.
Storm Shadow entered service with the
Royal Air Force in 2002. It was first used during the
2003 invasion of Iraq by
No. 617 Squadron.
On 12 September 2006 three Italian
Tornado IDS left for South Africa to complete the integration of the Storm Shadow.
Future development
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 for future weapons .
