GKN Aerospace reveals role in BAE Systems secret Brontanax combat drone

GKN Aerospace has completed the engineering, manufacture and full prototype integration of the wings, fins and control surfaces of Brontanax, the uncrewed Collaborative Combat Aircraft (CCA) unveiled by BAE Systems at the Farnborough International Airshow on July 22, 2026. 

The announcement offers the first detailed look at the supply chain behind an aircraft that BAE Systems developed largely in secret at its Warton site in Lancashire. GKN Aerospace said the structures were delivered flight-ready, having progressed from a clean-sheet design within what it described as an accelerated timeline. 

Composite work at Cowes 

The components were produced at GKN Aerospace’s composite design and assembly facility at Cowes, on the Isle of Wight, a site the company says marks 125 years of aerospace activity this year. The work drew on capabilities coordinated across several of the group’s sites. 

BAE Systems has positioned Brontanax as a pre-series, pre-production prototype, with its FalconWorks rapid development unit leading the design. The manufacturer has committed more than £400 million ($535 million) of its own funding since concept work began in 2022, drawing on more than 500 employees and around 75 UK suppliers. 

The aircraft is roughly the size of a Hawk trainer, with a maximum take-off weight above five metric tons. The prototype flies with a Williams International engine, although BAE Systems expects to transition to a powerplant from Rolls-Royce’s Orpheus family. Power-on is scheduled for the end of the third quarter of 2026, followed by ground trials in the first half of 2027 and a first flight later that year. 

Brontanax is BAE Systems’ answer to the Royal Air Force’s Storm Fighter requirement, under which the latest Defence Investment Plan allocates £300 million ($400 million) to loyal wingman development.

The company signed a partnership with Anduril UK on December 9, 2025, covering next-generation UAV solutions, and in May 2026 said it would support the next phase of Project NYX, the British Army’s effort to field an uncrewed teammate for the Apache. Anduril was one of four companies retained on that program on May 15, 2026.The post GKN Aerospace reveals role in BAE Systems secret Brontanax combat drone appeared first on AeroTime.
