BAE Systems unveils Brontanax, UK's first autonomous fighter drone

BAE Systems has unveiled the UK's first uncrewed autonomous Collaborative Combat Aircraft (CCA) at the Farnborough International Airshow. The prototype, named Brontanax, is designed to extend combat mass by complementing crewed aircraft at lower cost, the company stated.

Development and Design

The aircraft was designed and built by engineers at BAE Systems' site in Warton, Lancashire, which the company describes as the home of the UK's sovereign combat air industrial capability. According to BAE Systems, more than 500 of its employees have been involved in the aircraft's development to date, working with over 75 large companies and SMEs from across the British aerospace sector.

🇬🇧 Meet Brontanax: BAE Systems has unveiled the UK's first uncrewed autonomous Collaborative Combat Aircraft at Farnborough. Designed to fly alongside Typhoon and extend combat mass at lower cost, it's set for ground testing at Warton ahead of a first flight next year. 🎥👇 — UK Defence Journal (@UKDefJournal) July 22, 2026

Capabilities and Role

Brontanax is intended to provide electronic warfare and precision strike capabilities against airborne and ground targets. Operating with frontline combat aircraft such as the Typhoon, the company says it will enhance combat mass and operational effectiveness, with planned availability to enter service before the end of the decade.

Similar in size to a BAE Systems Hawk, the aircraft is designed to be operated by a Typhoon pilot or mission commander from range, allowing crewed and uncrewed aircraft to operate as a team. It has been developed with an open architecture and modular design that, according to the company, can be adapted as threats evolve.

Government and Military Response

Defence Secretary Wes Streeting said:

"The unveiling of Brontanax, the UK's first uncrewed autonomous Collaborative Combat Aircraft, is a testament to the extraordinary talent and innovation across our sovereign defence industry. Built at BAE Systems in Warton by British engineers, backed by British businesses large and small, this aircraft demonstrates that the UK has the skills, the technology and the determination to lead the world in combat air power. We're investing £300 million in our StormFighter programme to develop an autonomous combat aircraft here in the UK. This launch shows the depth of industrial capability we have here in Britain to help deliver our ambition to become Europe's first sixth generation air force."

Chief of the Air Staff Air Marshal Sir Harv Smyth said:

"The RAF is determined to become Europe's first 6th Generation Air Force, driving innovation and accelerating the adoption of cutting-edge technology to stay ahead in an increasingly complex and contested battlespace. Working alongside BAE Systems, we are taking a major step towards that ambition, with a prototype expected to fly next year. Backed by £300 million through the Defence Investment Plan, our StormFighter programme is transforming future capability, while the launch of Brontanax, the UK's first autonomous uncrewed Collaborative Combat Aircraft, shows how sovereign defence industry is delivering at pace to support us in being agile, integrated and ready to fly, fight and win."

Industry Perspective

Simon Barnes, Group Managing Director of BAE Systems' Air sector, said:

"We recognise armed forces are being challenged to meet the demands of speed, adaptability and scale. Our Collaborative Combat Aircraft will provide the ability to extend the reach of crewed aircraft, generating greater combat mass at lower cost, while keeping pilots out of harm's way. This capability represents a significant company investment in the UK's future of air power and builds on our long-standing commitment to innovation. Alongside supporting defence priorities, it will strengthen the UK's sovereign defence ecosystem by creating opportunities for SMEs, suppliers and partners across the country."

Background and Funding

The unveiling follows the publication of the government's Defence Investment Plan, which confirmed a £300 million commitment to the StormFighter sovereign autonomous CCA programme, intended to provide the Royal Air Force with what the government describes as Europe's first sixth generation capability.

BAE Systems states that Brontanax builds on more than 25 years of company experience in uncrewed and autonomous systems, and has been developed through its FalconWorks team and funded to date through self-funded research and development. The company invested more than £400 million in self-funded R&D in 2025.

Name and Next Steps

The prototype name is derived from the ancient Greek words for thunder and king. The aircraft is now being prepared for ground-based testing at Warton ahead of flight testing within UK airspace, which the company expects to begin next year.
