LONDON : The UK Ministry of Defence has awarded BAE Systems a £453.5 million contract for the full-scale production of a next-generation radar system for the Royal Air Force’s Eurofighter Typhoon fleet, a move that significantly strengthens Britain’s air combat and electronic warfare capabilities amid a deteriorating European security environment.
The contract covers the production and integration of the ECRS Mk2 radar, an advanced active electronically scanned array (AESA) system designed to give Typhoon aircraft a decisive edge in contested airspace. The award follows several years of development, testing and risk-reduction work funded through sustained UK government investment and is described by defence officials as one of the most substantial upgrades to the Typhoon platform since it entered service.
Once fielded, the ECRS Mk2 will be integrated across the RAF’s full fleet of Tranche 3 Typhoon aircraft, with entry into operational service expected before the end of the decade.
A Step Change From Mk1 to Mk2
The ECRS Mk2 represents a major evolution from the earlier ECRS Mk1 radar currently being introduced on Typhoon aircraft. While the Mk1 focuses primarily on improving traditional radar performance — including greater detection range, faster target tracking and improved reliability over legacy mechanically scanned systems — the Mk2 is designed as a multi-role sensor and electronic warfare system.
Unlike the Mk1, which is optimized mainly for air-to-air and air-to-ground sensing, the Mk2 incorporates advanced electronic attack and electronic protection functions. This allows the radar not only to detect and track multiple targets simultaneously but also to disrupt, deceive or suppress hostile radar and air-defence systems. The system can dynamically switch between surveillance, targeting and electronic warfare modes, providing pilots with greater flexibility in high-threat environments.
Defence sources describe the Mk2 as a “sensor-effector,” blurring the traditional line between radar and electronic warfare equipment. The upgrade is particularly significant in the context of modern conflicts, where aircraft are increasingly required to operate inside dense, networked air-defence zones.
Enhanced Capabilities for Modern Warfare
The ECRS Mk2’s AESA architecture allows thousands of transmit-receive modules to be controlled electronically rather than mechanically, enabling near-instantaneous beam steering, greater resilience to jamming, and improved performance against low-observable targets. The radar is capable of detecting, identifying and tracking multiple airborne and surface targets at long range while maintaining a low probability of intercept, reducing the chance of detection by adversaries.
In electronic warfare roles, the Mk2 can generate focused, high-power electronic effects to degrade or deny enemy sensors, offering Typhoon crews a powerful self-protection and force-multiplier capability. This is seen as particularly relevant as Russian and other state-level air-defence systems become more sophisticated and continue to proliferate across active conflict zones.
The upgrade also enhances Typhoon’s ability to share data across NATO networks, improving interoperability with allied aircraft, ground forces, and command-and-control systems.
Industrial Impact and UK Jobs
The contract is expected to support around 1,300 skilled jobs across the UK defence sector, including approximately 400 roles at Leonardo and more than 120 positions at BAE Systems, with the majority of employment concentrated in Scotland and the North West of England.
Leonardo UK will lead the design and manufacture of the radar hardware at its facilities in Edinburgh and Luton, while BAE Systems will oversee system integration and aircraft modification at its Lancashire sites. Under the current programme, the companies will deliver 38 ECRS Mk2 radars.
The broader Typhoon programme supports more than 20,000 UK jobs annually and generates approximately £1.4 billion in exports each year, with total export sales exceeding £30 billion since the aircraft entered service.
Strategic Context and Government Messaging
Richard Hamilton, Managing Director for Air Operations at BAE Systems Air, described Typhoon as a cornerstone of the UK’s defence posture. “The Typhoon programme is a fundamental pillar of the UK’s national defence and security,” he said, noting the aircraft’s role at the heart of NATO air policing missions, particularly along Europe’s eastern flank.
UK Defence Secretary John Healey framed the radar upgrade within the wider geopolitical context, describing the Typhoon fleet as the backbone of UK and NATO air defence. He highlighted the growing threat from Russian drone and missile activity and repeated violations of NATO airspace, adding that the ECRS Mk2 will help keep Britain secure at home and strong abroad for many years to come.
Future-Proofing the Typhoon Fleet
Defence analysts see the ECRS Mk2 radar as a critical step in keeping the Eurofighter Typhoon operationally relevant well into the 2030s, particularly as the UK advances development of its Global Combat Air Programme (GCAP). The radar is also viewed as a technology bridge, allowing advanced sensor fusion and electronic warfare techniques to mature ahead of the next generation of combat air platforms.
With the £453.5 million production contract now in place, the UK has sent a clear signal that it intends to maintain Typhoon as a front-line, high-end combat aircraft capable of operating in the most demanding threat environments — a message aimed at allies, industry, and potential adversaries alike.
