Attritable, not expendable: how the RAF will account for losses.
The word attached to CCAs across every Western air force is "attritable", and it is doing an enormous amount of work. It sits between expendable, which means the aircraft is consumed on use, and exquisite, which means each loss is a national event. Where exactly Brontanax lands on that spectrum will shape how commanders actually use it — and no cost figure alone answers the question.
- Sunday, 2 August 2026The autonomy stack question
BAE Systems' autonomy heritage is genuine. Taranis flew a decade ago as one of the most advanced unmanned combat air demonstrators anywhere in the world. Mantis matured beyond-line-of-sight operations. Concept 2 pushed the manned-unmanned teaming envelope in simulation. The question with Brontanax is not whether BAE can do autonomy — clearly it can — but how much of that inherited capability is genuinely mission-ready on the timescales the programme has promised.
autonomy - Saturday, 1 August 2026The engine question BAE has not yet answered
BAE Systems has named Rolls-Royce as the propulsion partner for Brontanax without naming an engine. That silence is deliberate and worth reading carefully. The propulsion decision shapes almost every other parameter of the aircraft: unit cost, range, payload fraction, infrared signature, sustainment burden and, critically, exportability.
propulsion - Friday, 31 July 2026How Brontanax stacks up against US Increment 1 CCA
The US Air Force's Increment 1 Collaborative Combat Aircraft programme is the closest live comparator to Brontanax and, on hardware, it is already a generation ahead. The General Atomics YFQ-42A and Anduril YFQ-44A prototypes have both flown, both are being wrung out through structured flight-test campaigns, and the USAF has a clear path to an initial operational capability well before Brontanax reaches first flight.
comparators - Thursday, 30 July 2026The GCAP link that ties Brontanax to Tempest
The £708 million GCAP contract awarded around Farnborough 2026 is legally separate from Brontanax funding, but operationally the two programmes are inseparable. Any autonomy architecture, sensor fusion approach or secure teaming data-link that survives on Brontanax becomes a candidate to migrate into the Tempest crewed fighter later in the decade. That is not an accident; it is the whole point of running the two programmes in parallel under a single UK industrial lead.
programme - Wednesday, 29 July 2026Runway independence and where Brontanax would fly from
A drone designed for European high-intensity conflict has to answer a question the Typhoon fleet has largely been able to avoid: what happens when the main operating base is cratered in the first hours? NATO air forces have spent the last three years rediscovering dispersed operations, and any aircraft entering service in the 2030s will be judged partly on how little infrastructure it needs.
basing - Tuesday, 28 July 2026Weapons: what Brontanax will actually carry
Nothing in the Farnborough material told us what Brontanax will be armed with, and that omission matters more than most of the specification gaps. Weapons integration determines internal bay geometry, electrical and data interfaces, release-clearance workload and, ultimately, whether the aircraft can be sold abroad without a multi-year certification programme for every new customer munition.
weapons - Monday, 27 July 2026Ratio watch: how many drones per fighter, really
The indicative four-to-one ratio of Collaborative Combat Aircraft to crewed fighters shown around the Brontanax reveal is not doctrine. Air Chief Marshal Sir Gerry Mayhew was explicit at Farnborough that the figure is illustrative — a placeholder to help journalists and politicians visualise the concept, not a settled operational construct. The real ratio will emerge over years, driven by three constraints that rarely make headlines.
force-mix - Sunday, 26 July 2026The MQ-28 Ghost Bat parallel to watch closely
Boeing Australia's MQ-28 Ghost Bat is the one loyal-wingman aircraft already flying in the same size and role bracket the RAF has described for Brontanax. Watching how Ghost Bat integrates with the Royal Australian Air Force's F-35A and E-7A fleets over the next eighteen months is probably the most useful predictor available for what the RAF should expect from Brontanax, and where BAE Systems will need to leapfrog.
comparators - Saturday, 25 July 2026The cost curve that has to hold
FalconWorks' headline number for Brontanax — 70 to 80 per cent of a Typhoon's combat effect at 20 to 25 per cent of its cost — is the single most important figure BAE Systems has attached to the aircraft. Every export pitch, every Treasury argument for buying meaningful fleet numbers, and every RAF slide about mass in a contested European air battle ultimately trace back to whether that ratio survives contact with real integration work over 2026 and 2027.
cost - Friday, 24 July 2026Sovereignty is the word that will be tested
"Sovereign" is the word BAE Systems and the MoD keep using around Brontanax, and it is the word that will be tested hardest over the next two years. The programme's political case rests on the claim that this is a genuinely British aircraft, designed, built and sustained by a UK supply chain, with UK intellectual property in the parts that matter. That claim is defensible today. Keeping it defensible through first flight and into series production is a different problem.
industrial-base - Thursday, 23 July 2026The export map BAE is quietly drawing
BAE Systems' insistence that Brontanax is built to an open architecture is not a technical footnote — it is a targeted message to export customers, and the Middle East in particular. The Gulf states have spent the last decade demonstrating that they will not buy combat aircraft they cannot modify. Indigenous munitions, national sensor packages and sovereign mission software are now table-stakes for any serious pitch to Riyadh, Abu Dhabi or Doha.
exports - Wednesday, 22 July 2026Steadfast Defender 27 and the political first flight
Timing Brontanax's first flight to NATO's Steadfast Defender 27 exercise transforms an engineering event into a political showcase. A first flight in a hangar circuit at Warton is a milestone for BAE Systems and the MoD. A first flight that ties into an alliance-wide exercise, watched by every European air chief, is something else entirely — it is a statement of intent.
schedule - Tuesday, 21 July 2026Project Vanquish and the carrier variant nobody quite promised
The BAE Systems promotional footage of a Brontanax launching from a Queen Elizabeth-class carrier was almost certainly deliberate. The MoD brief around the Farnborough reveal was firmly RAF-focused — StormFighter, land-based operations, Typhoon and Tempest teaming — but the CGI carrier launch quietly opened a second front. The Royal Navy's Project Vanquish is looking for a jet-powered uncrewed platform that can operate from a QE-class deck without catapults or arrestor gear, and Brontanax is one of a very small number of candidates that could plausibly meet that requirement with modification.
maritime - Monday, 20 July 2026How Brontanax stacks up against US Increment 1 CCA
The US Air Force's Increment 1 Collaborative Combat Aircraft programme is the closest live comparator to Brontanax and, on hardware, it is already a generation ahead. The General Atomics YFQ-42A and Anduril YFQ-44A prototypes have both flown, both are being wrung out through structured flight-test campaigns, and the USAF has a clear path to an initial operational capability well before Brontanax reaches first flight.
