France test-fired its hypersonic demonstrator vehicle for the first time on 26 June, the Directorate General of Armaments (DGA) announced.
The VMaX hypersonic glide vehicle (HGV) demonstrator was launched from a ground-based rocket at the Biscarosse test facility on the southern French Atlantic coast.
“This first demonstrator contained many onboard technological innovations. Its flight test, on a very demanding long-range trajectory, was an unprecedented technical challenge that paves the way for the future of our national hypervelocity road map,” the DGA said.
According to the DGA, technical analyses of the data recovered from the test are under way to draw lessons for the continuation of the experimental flights.
While technical details pertaining to the VMaX have not been released, it is understood to fly at Mach 5, which is the gateway speed for hypersonic capability. News of the test was disclosed shortly after imagery was posted online showing irregular contrails high in the sky over the test site.

The new Ariane 6 rocket will launch the initial batch of Galileo Second Generation (G2G) navigation satellites into orbit in 2026 and 2027, Arianespace announced on 29 April.
A total of four G2G satellites will be sent into orbit on Ariane 6 over two separate launches in 2026 and 2027. Airbus Defence and Space and Thales Alenia Space are each building six satellites, which together form the first fleet of G2G satellites, the company detailed.
The G2G satellites will use electric propulsion and host a more powerful navigation antenna as well as improved atomic clocks and fully digital payloads compared with the first-generation Galileo satellites. Each spacecraft will weigh 2,000 kg, orbiting at an altitude of 23,222 km (medium Earth orbit).

Kaman's Kargo medium-lift unmanned aerial vehicle (UAV) has been in flight-testing since December 2023, the company's general manager, Romin Dasmalchi, told Janes in advance of Modern Day Marine on 24 April.
The UAV first flew while tethered to the ground for safety reasons. The tether has since been removed, Dasmalchi said, and the first Kargo is free-flying at an undisclosed UAV testing site in Pennsylvania.
Following a flight, Dasmalchi said, “You would make an adjustment – call it a tuning adjustment – and then you fly it for a short period. You give it some inputs manually to see how it handles, then you land and you make adjustments. We probably did hundreds of those evolutions.” The Kargo might undergo 20 to 30 flights per day.
As of 26 April the first Kargo craft had accrued around 50 hours of flight time, Dasmalchi said, and hundreds of ignitions of its Rolls-Royce RR300 engine. Aside from changes to antenna placement, Dasmalchi anticipated no major changes to Kargos in production based on the results of flight-testing to date.

The US Air Force (USAF) awarded Sierra Nevada Corporation (SNC) a USD13 billion contract to build the Survivable Airborne Operations Center (SAOC), intended to replace the Boeing E-4B Nightwatch as the service's airborne nuclear command-and-control aircraft and primary transport for the secretary of defence. The contract was announced on 26 April, and is set to run through July 2036.
The contract covers ground support systems, including mission trainers, maintenance trainers, and system integration laboratories, among other necessary equipment.
“To satisfy operational requirements, the weapon system will be comprised of a commercial derivative aircraft that will be hardened and modified to meet military requirements,” said the USAF in the contract announcement. “Additionally, the mission system will integrate secure communications and planning capabilities on modern information technology, infrastructure, based on a Modular Open System Approach (MOSA).”
The number and type of aircraft included in the contract are publicly undisclosed, but the USAF currently operates four E-4Bs, which entered service in 1980 according to Janes C4ISR & Mission Systems: Air and are approaching the end of their service lives.
