BAE Systems and Leonardo have been awarded a contract to develop the Active Electronically Scanned Array (AESA), the European Common Radar System Mark 2(ECRS Mk2) radar, to a standard ready to be integrated on to RAF Typhoons.
It will sustain more than 600 highly skilled jobs across the country, including more than 300 at Leonardo’s site in Edinburgh, over 100 electronic warfare specialists at the company’s site in Luton, and 120 engineers at BAE Systems’ site in Lancashire.

The ECRS2 is a multi-functional array (MFA) that will give UK Typhoons a world-leading Electronic Warfare capability, in addition to traditional radar functions, including wide band Electronic Attack. It will equip RAF pilots with the ability to locate, identify and suppress enemy air defences using high-powered jamming. They can engage targets whilst beyond the reach of threats – even when they’re looking in another direction – and operate inside the range of opposing air defences, remaining fully protected throughout. This game-changing capability will replace the mechanically-scanning radar that RAF Typhoons are currently equipped with and will ensure the UK retains the freedom to deliver air power wherever and whenever it is needed. It also enables the Typhoons to link up with future data-driven weapons to combat rapidly evolving air defences, ensuring that UK Typhoons can continue to dominate the battlespace for years to come. 

Andrea Thompson, Managing Director Europe & International for BAE Systems’ Air sector, said:

“This capability will allow Typhoon to take its place in the future battlespace for decades to come, maturing key technologies for future combat air systems and ensuring interoperability. As well as securing highly skilled jobs, it will sustain the key skills needed to keep the UK at the forefront of the global Combat Air sector. We look forward to continuing to work alongside the Eurofighter nations and our industry partners to ensure Typhoon delivers the needs of today and answers the challenges of tomorrow.”

Mark Hamilton, Senior Vice-President Electronic Warfare, Leonardo, said:

“This contract is great news for the UK, which will get the world’s most capable fighter radar, and great news for British engineering. Inventing, developing and building advanced technology here in the UK allows us to understand and meet the specific requirements of our Armed Forces and to secure export orders all around the world, boosting the whole UK economy.” The new radar will be based on Active Electronically Scanned Array (AESA) technology and will provide game-changing capabilities based on a revolutionary MFA. It has significantly more Transmit-Receive Elements than other radars, making Mk2 the most capable fighter AESA radar in the world, maintaining the same power and precision of traditional radars but also enabling the simultaneous operation of its wide-band Electronic Warfare functionality. BAE Systems, the UK’s prime contractor for the Typhoon, will integrate the new sensor which will be developed by Leonardo, the UK’s defence electronics champion.

Both companies are currently working as part of a four-nation development programme alongside Eurofighter consortium partners in Germany, Spain and Italy on a baseline version of the AESA radar. The ECRS Mk2 is a completely new approach designed to meet the operational needs of the RAF and future export customers. The UK’s commitment follows a similar commitment from Germany and Spain to deliver their own national requirements for an AESA radar.
