Britain’s Sovereign Hypersonic Strike Effort Enters New Phase
The UK is progressing an ambitious national endeavor to join the growing number of countries capable of developing hypersonic weapons.
A £1 billion ($1.34 billion) initiative launched three years ago has now attracted more than 120 companies—and others waiting in the wings—as well as generated more than 25 research and development contracts and successfully tested propulsion systems.
Led by the UK Defense Ministry’s Team Hypersonics, the initiative is entering its next phase. Engineers are designing a hypersonic cruise missile flight-test vehicle, the Scalable Hypersonic Advanced Ramjet Demonstration (SHARD), that the country hopes to fly in 2030.

Last year’s Strategic Defense Review described hypersonics as a technology that is redefining warfare, enabling penetrating weapons that can evade the current generation of air defenses. China and Russia already have introduced such weapons into their arsenals; Western countries are playing catchup.
Success would pave the way for sovereign UK hypersonic weapons while strengthening the country’s ability to collaborate internationally.
The recently published Defense Investment Plan allocates £770 million over four years to support the development of a new generation of 2,000-km-range (1,200-mi.) deep-strike missiles under the Trinity House Agreement with Germany.
The UK also is collaborating with Australia and the U.S. through the AUKUS security pact, which has made hypersonic weapons and enabling technologies a priority.
UK industry and academia are no strangers to hypersonic flight and the challenges associated with developing air vehicles capable of operating at extreme velocities and temperatures. In the early 2000s, the UK Defense Ministry supported the HyShot dual-mode ramjet/scramjet engine research and helped fund the Sustained Hypersonic Flight Experiment (SHyFE) to explore technologies for a hypersonic missile. However, as the conflict in Afghanistan drained resources at the time, interest in SHyFE faded, and the trials were called off.
Fortunately, that work was not in vain. The experts who worked on HyShot and SHyFE are now supporting Team Hypersonics, says Paul Wilson, head of Team Hypersonics UK. “We are not starting cold,” Wilson tells Aviation Week. “Hypersonics is not a stand-alone technology; it requires a range of the UK’s existing highly skilled and world-leading disciplines across multiple industrial sectors. So we are extending, rather than establishing, their capacity and expertise.”
One of the first steps in the journey was the creation of a Hypersonic Technologies and Capability Development Framework (HTCDF), which has led to what Wilson calls a “collective partnership” of small, medium and large industry players (AW&ST July 31-Aug. 13, 2023, p. 17).
Wilson says the framework and its low barrier to entry have helped both to prepare the supplier base and to set rapid procurement timelines. Some £50 million has been spent since July 2024 on developing technologies and testing as well as building academic skills and training.
The HTCDF is split into eight workstreams, including modeling, airframe and power generation, propulsion, computing, seekers, lethal packages, low-technology-readiness-level packages and academic work packages. Contracts have been awarded through all but the lethal packages workstream.
Team Hypersonics issued a £12 million contract in December for an Industry Mission Partner to develop the design for the flight-test vehicle. A joint team from the UK’s Defense Science and Technology Laboratory and the U.S. Air Force Research Laboratory completed 233 static engine tests of an air-breathing engine in early 2025. Testing spanned the full flight Mach number range from supersonic to hypersonic speeds. The tests validated the robustness of the engine design, engineers said at the time.
Officials say work is continuing in support of a series of large-scale tests planned for next year.
Those partnerships have enabled the UK to move “rapidly toward fully sovereign capability,” Wilson says. Technology maturation is benefiting both hypersonic cruise missile and hypersonic glide vehicle development. Reusable systems are outside the program’s scope.
The HTCDF also includes several international companies that have helped accelerate progress in large-scale testing and integration.
Team Hypersonics says international suppliers are welcome to contribute to the framework, but the UK Defense Ministry could choose to restrict some activities to domestic suppliers for national security considerations.
In addition to the work on the demonstrator, Team Hypersonics and its industry partners are playing a role in accelerating the Thresher concept, revealed by Aviation Week in 2020 (AW&ST, April 6-19, 2020, p. 14), and the HyLarc UK-U.S. hypersonic technology initiative being run in collaboration with AUKUS partners under the Hypersonic Flight-Test and Experimentation Project Arrangement.
For Wilson, the objective extends beyond a single demonstrator. The ambition is to rebuild a sovereign hypersonics enterprise capable of designing, testing and producing future generations of high-speed weapons in the UK.
