Brontanax
BAE Systems · United Kingdom · Updated
Brontanax is an uncrewed collaborative combat aircraft (CCA) demonstrator that BAE Systems unveiled at the Farnborough International Airshow in July 2026, built at its Warton site as the UK's entry for the Royal Air Force's StormFighter requirement. BAE describes it as the UK's first sovereign, British-designed CCA, intended to fly and fight alongside crewed aircraft such as the Typhoon.
Overview
BAE Systems' FalconWorks rapid-development team designed and built Brontanax at Warton, Lancashire, revealing the prototype on 22 July 2026. The company says more than 500 BAE employees, supported by over 75 other companies and SMEs, worked on the aircraft, and that the programme to date has been funded from BAE's own research and development budget rather than government money. Brontanax is BAE's proposal for StormFighter, the UK Ministry of Defence's sovereign autonomous collaborative combat aircraft programme; the UK's Defence Investment Plan has allocated £300 million to StormFighter, which is expected to fund the programme's next phase of development.
BAE positions Brontanax as a lower-cost complement to crewed fast jets rather than a replacement for them: a company spokesperson has said it could cost around one-quarter as much as a Typhoon, and FalconWorks engineering lead Dave Holmes has said it could fly 70–80% of a Typhoon's missions at 20–25% of the cost. BAE has not published figures to support these estimates, and they are company claims rather than verified costs. The Royal Air Force has linked the programme to its ambition to become "Europe's first sixth-generation air force," in the words of Air Marshal Sir Harv Smyth.
Design and capabilities
BAE has released few technical details. The company says Brontanax is roughly the size of its Hawk trainer jet and has a tailless, blended-fuselage, swept-wing airframe, built around an open, modular architecture that BAE says can be adapted as threats evolve; one trade report links its control system to the UK Ministry of Defence's Pyramid open avionics reference architecture. The aircraft is designed to be uncrewed but directed by a Typhoon pilot or a ground-based mission commander, so that crewed and uncrewed aircraft can operate as a team, and BAE has said it is intended for electronic warfare and precision strike against airborne and ground targets. BAE has not disclosed Brontanax's dimensions, weight, engine, payload, range or endurance.
Operational history
Brontanax has not yet flown. As of its July 2026 unveiling, BAE said the aircraft was moving into ground-based testing at Warton ahead of flight trials, which the Royal Air Force expects to begin in 2027; the programme's goal is to enter service before the end of the decade. No operator has taken delivery and no production contract has been announced.
