MBDA is working in partnership with Leonardo to develop a new electronic warfare version of the SPEAR weapon system — SPEAR EW — which brings enhanced Suppression of Enemy Air Defence (SEAD) capability to Eurofighter. Chris Stevens, MBDA’s Head of Air Domain Sales for the UK, reveals how this revolutionary new capability could be a game-changer for Eurofighter.


SPEAR EW uses the SPEAR missile as its baseline but, instead of a warhead and seeker, the payload is an Electronic Warfare (EW) device which is a state-of-the-art electronic jammer designed to confuse adversaries and keep pilots safe.

At the heart of SPEAR EW is a miniaturised EW payload from Leonardo, based on the company’s innovative Digital Radio Frequency Memory (DRFM) technology used in its BriteCloud Expendable Active Decoy. 

It uses less capacity than a conventional warhead and this extra volume means there’s additional fuel capacity.

Hence, what looks and behaves exactly like a normal SPEAR has three times the range. Using the existing SPEAR architecture as the starting point has a number of other advantages. SPEAR EW’s power, weight, and centre of gravity remain exactly the same so integration is relatively straight-forward because activities that normally bring a level of complexity like flight test and separation clearance are already carried out.



It marks a fundamental change in the ability of friendly air forces to conduct their missions despite the presence of enemy air defences. SPEAR EW acts as a stand-in jammer which greatly increases the survivability of the Eurofighter by suppressing enemy air defences. It can be used for multiple different types of EW. At one end of the spectrum it could simply jam a radar, effectively blinding it, and at the other it could mimic 100s of different objects, therefore creating a mask.

This flexibility gives a pilot a range of options. Blinding a threat radar is an overt action but they can call on more subtle effects. For example, SPEAR EW can be used to create a decoy by making you appear bigger or appear as though there are 50 targets so that it’s impossible for an adversary to determine which is the real target.

Alternatively, you might want to encourage the threat target to start shooting which would enable your forces to find it. Another option could be to get the adversary to train their fire at an imaginary target and therefore allow you through their defences.

SPEAR EW isn’t simply restricted to land targets. It could be used for maritime strike to blind or confuse a ship.


Electronic Warfare has many guises and Eurofighter already boasts strong capability, while future enhancements promise even greater offensive capability. However, dedicated EW attacks require huge amounts of power. There’s also a limitation of how far a platform like Eurofighter can project these kinds of effects. That’s where SPEAR EW comes into its own. It means EW effects can be projected either over a long distance or for a long time, whilst allowing the pilot to retain the ability to use the aircraft’s own sensors for effects.
Eurofighter already has the ability to carry a mixed payload depending on the mission, so for example, you could carry three SPEAR EWs and nine regular SPEAR missiles.


In a word, no. Compressed to a size that no-one else can match, Leonardo’s Digital Radio Frequency Memory (DRFM) technology leads the way in terms of miniaturised technology. Taking the DRFM technology as used in BriteCloud and combining it with SPEAR, provides an EW capability that’s unrivalled.


MBDA and Leonardo have been awarded a contract to carry out a Technical Demonstration Programme (TDP) by Defence Equipment & Support (DE&S). This one-year contract continues the development work already carried out by MBDA and Leonardo.
This will enable that work to mature. One of the aims is to keep development of SPEAR EW as closely aligned with the main SPEAR programme as possible to ensure any integration work is as seamless as possible.


MBDAs vision for SPEAR is to create a swarm of network-enabled miniature cruise missile weapons able to saturate and neutralise the most sophisticated air defences. Adding SPEAR-EW alongside complementary variants of the SPEAR family will add significant capability and force multiplication without the need to repeat the platform integration. There is a roadmap of variants, spirals and technology insertions in the pipeline to further enhance the family.
