UK’s BAE enters uncrewed fighter competition with ‘Brontanax’

FARNBOROUGH, England, July 22 (Reuters) – BAE Systems revealed a new unmanned fighter jet on Wednesday, boosting Britain’s entry into one of the defence industry’s hottest and most fiercely contested markets.

The UK’s biggest defence company showcased a model of its new ​jet, Brontanax, derived from the ancient Greek words for thunder and king, at the ‌Farnborough Airshow. It is about the size of a Hawk trainer and would be ready to start flight testing next year, BAE said.

As the global threat level rises and western nations re-arm, defence chiefs say the lesson from the Ukraine war is clear: nations need to control the skies to avoid Ukrainian-style attritional trench warfare and that ‌requires air ​forces to bulk up.

BAE enters an increasingly crowded market for ⁠so-called Collaborative Combat Aircraft, with Airbus, ⁠Boeing, Anduril and General Atomics among a growing number of companies competing for business at Farnborough in a sector expected to expand rapidly.

Often described as “loyal wingmen,” CCAs are designed to fly alongside piloted aircraft and are expected to cost roughly a third as much as a ​traditional fighter jet.

CROWDED MARKETPLACE

Britain’s new Defence Secretary Wes Streeting, who was appointed on Monday, said it was a “groundbreaking moment”.

“We will adopt this as our operational concept demonstrator, and we’re going to get ⁠it in the air in 2027,” he said at ⁠the airshow.

BAE has invested hundreds of millions of pounds in its CCA, ​pushing ahead without the government co-investment which usually underpins new platforms.

“We’ve put our money where our mouth ​is,” CEO Charles Woodburn told Reuters.

“We could see where the market was going,” he ‌added, saying he hopes to secure a UK order, and that other countries in Europe and the Middle East could follow, with some already showing an interest.

BAE has developed Brontanax alongside the Royal Air Force, in a project dating back to 2022, and already has a fully assembled aircraft at ⁠its Warton facility in northwest England. It could enter service by 2030, BAE said.

That timeline compares to Boeing’s MQ-28 Ghost Bat, on display at Farnborough, which has already started flight testing, and could be ⁠flying for Australia by 2028.

BAE ‌said its CCA offered more stealth than rivals and it was aiming ⁠for it to have 70% to 80% of the capabilities of a ​fighter ‌jet and to come in at under 25% of the cost, which ​could give ⁠it a price tag of around $25 million.

Its open architecture and modular design will allow software upgrades and changes to easily be made, with BAE looking at non-military suppliers to help with the build.

Britain said in its defence investment plan earlier in July that it would spend an initial £300 million ($401.10 million)  to launch a sovereign CCA programme it has named Storm Fighter.
