21 July — Raytheon UK unveiled Red Kite at the Farnborough International Airshow, presenting what the company calls a domestically designed and digitally engineered glide weapon intended to give the Royal Air Force a lower-cost, high-volume precision munition.
Red Kite reuses the StormBreaker airframe
Raytheon UK developed Red Kite over five years and deliberately reused the airframe of the GBU-53/B StormBreaker rather than redesigning it. The source weapon, StormBreaker, is described as “already integrated on the F-35B, F/A-18 and F-15 and manufactured in Europe before export to the United States.” By preserving that airframe the company said it could draw on StormBreaker’s manufacturing scale and integration maturity while focusing United Kingdom investment on internal subsystems.
Guidance, patents, and a deliberate datalink choice
According to Richard Gates, Raytheon UK’s head of weapons, the guidance section of Red Kite “was designed and coded in‑house,” with several patents pending. Gates also said Red Kite carries no integrated datalink at this stage — a “deliberate cost decision” — while the design permits a datalink to be added later if customer requirements change.
Digital engineering and the programme’s ‘digital twin’
Raytheon UK emphasised digital modelling throughout development. The company described the programme’s digital twin as “functionally inseparable from the weapon itself,” allowing software changes to be validated in hours rather than the roughly six months a legacy Paveway update requires. The firm framed that method as aligned with the Ministry of Defence’s push — citing Defence Equipment and Support’s argument that digital engineering will let designs be tested virtually thousands more times than is physically possible.
United Kingdom supply chain and jobs
The supply chain for Red Kite is spread across England, Scotland and Wales. Raytheon UK said control actuation is produced at Glenrothes in Fife, the fuse in Reddington and Glasgow, and the warhead in Glascoed. The company estimates around 140 skilled jobs across the three nations will directly support the programme. Raytheon UK employs more than 2,000 people in the country as a supplier and systems integrator to the Ministry of Defence.
Role for the RAF: “high‑low mix,” range claims, and platform fit
Executives positioned Red Kite as the low end of a “high‑low mix,” intended to sit below powered weapons such as SPEAR Cap 3 while offering substantially greater stand‑off range than Paveway IV. Raytheon UK treats SPEAR Cap 3 as a distinct, powered capability rather than a competitor. The company claimed Red Kite achieves a multiple of Paveway IV’s range but did not supply specific figures. Raytheon UK said Red Kite is optimised for the Eurofighter Typhoon, with additional integration potential on the F‑35.
What this means for the RAF, Raytheon UK, and Defence Equipment and Support
- The Royal Air Force: Red Kite is pitched as a lower‑cost, high‑volume precision option to allow deeper stockpiles, and as a tool to address a capability gap Raytheon UK executives said has widened as threats have proliferated over the past 15 to 20 years.
- Raytheon UK: The company presented Red Kite as a step toward a more resilient, sovereign United Kingdom defence industrial base, emphasising domestic design, code, and a UK supply chain while arguing its Typhoon integration experience could compress the time to service.
- Defence Equipment and Support: The programme’s reliance on digital engineering dovetails with the organisation’s stated goal that virtual testing will multiply how often designs can be simulated before physical testing, a point Raytheon UK used to justify faster software validation.
Raytheon UK said further development work remains before Red Kite is ready for service, while arguing that reuse of StormBreaker’s airframe and an existing United Kingdom supply chain give the programme leverage to shorten that timeline. James Gray, the company’s managing director and chief executive, said the weapon was designed with affordability in mind and represents a step toward a more sovereign industrial base.
The unveiling frames Red Kite as part of a broader shift toward smaller, cheaper precision munitions designed for accuracy and stockpiling rather than larger warheads. The company pointed to recent conflicts as evidence that air campaigns can last longer than planners expect, reinforcing the case for weapons that are inexpensive enough to field in depth.
