Airborne ISR

Airborne Intelligence, Surveillance and Reconnaissance (ISR)

Raytheon UK’s Broughton site has emerged as the Airborne Solutions’ Centre of Excellence for technology research and development, as well as programme management for domestic and international customers.

We possess world leading expertise in the development, modification and support of surveillance equipment such as special missions aircraft like Shadow R1 and our previous Sentinel  R1, both vital airborne surveillance asset to the UK Ministry of Defence.

We are committed to technological innovation. We see the future of Airborne ISR in the development of multi mission solutions not dedicated to just single sensors or single capabilities, but which can overlay intelligence from multiple sensors to give a comprehensive overview of the battle space.

We will continue to invest in UK technology and Airborne ISR to ensure that the UK economy is protected and the country secure as a global power.

Sentinel R1 — Special Mission Aircraft

Sentinel R1

Sentinel R1, along with Shadow R1, was one of the UK Ministry of Defence's vital airborne surveillance assets until March 2021 following its retirement from operational service after 13 years. The Sentinel R Mk 1 was the airborne segment of the UK Airborne Stand-Off Radar (ASTOR) programme and provided long-range imagery intelligence (IMINT), including wide area surveillance of land and maritime, to UK and partner forces. Read more about some of the people who played a key role in the Sentinel story to share their memories here.


Shadow R1 — Special Mission Aircraft

Shadow R1

The Shadow R1 tactical C-ISTAR solution provides Airborne ISR in support of UK and international operations. Raytheon continues to develop the platform with an ongoing capability enhancement programme and the provision of in-service support. The aircraft is civil-certified by the Civil Aviation Authority and then released to service by the United Kingdom Military Aviation Authority.



Multi-Mission Aircraft

Multi Mission Aircraft

For Raytheon, the future of ISR airborne solutions lies in the development of multi-mission solutions for airborne platforms that are not dedicated to single sensors or single capabilities, but which can overlay intelligence from multiple sensors to give the decisionmaker a comprehensive overview of the battlespace.



Airborne Mission Management Systems — Spectus

Airborne Mission Thumb

Raytheon UK's Airborne Solutions team is the design authority for Spectus, a next-generation airborne mission management architecture that builds on the success of the ASTOR system and the Shadow R1 programme. Overseer combines intuitive user interfaces with a modular and flexible design to deliver a mission management system at the cutting edge, not only in terms of its software, architecture and open standards implementation, but also in its usability, trainability and maintainability — all critical elements to Raytheon customers around the world. Overseer's off-boarding capability allows it integrate with other ISR systems, and to be interoperable with a range of information exploitation systems.

Commercial Aviation Power & More Electric Aircraft


Raytheon's aerospace power solutions not only rise to the challenges of the More Electric Aircraft (MEA)concept — by reducing size and weight, and increasing power density — but they also deliver value for money to the customer; benefits that constitute our SWaP-V proposition.

The aerospace industry's drive to improve fuel consumption through airframe weight reductions is the catalyst for the rising demand for electrical power solutions being favoured over hydraulic and pneumatic mechanical systems and sub-systems for actuation on the MEA concept. Our high temperature silicon carbide technology is a game changer in the aviation power market, enabling smaller, lighter, more power-dense systems.
