Skyrora has successfully completed a 45-second static hot-fire test of a scaled-down version of its Skyrora XL orbital launch vehicle at Machrihanish on Scotland's west coast. The test marks another important step in the development of the company's three-stage orbital launch vehicle, designed to carry small satellites into low Earth orbit.

The test vehicle was built to validate subsystems and components similar to those that will be used in Skyrora XL. During the trial, engineers gathered critical data on the vehicle's pressurisation system and engine characteristics, including propellant flow rate and chamber pressure. Initial analysis indicates that all subsystems operated successfully throughout the test duration.

Testing at Scale: Reducing Risk Through Iteration

Skyrora's development philosophy centres on early, repeated testing of systems together before scaling them up to full size. By validating subsystems at a smaller scale, the company can identify and address engineering challenges earlier in the programme, reducing technical risk and building confidence in component performance before scaling up through an extensive programme of progressively larger and more demanding trials and integration into the Skyrora XL vehicle.

The company plans to conduct a second test as engineers continue to collate and analyse data from the Machrihanish trial. This incremental approach underpins Skyrora's broader testing strategy: test, learn, refine and test again.

Dr Jack James Marlow, Skyrora Chief Operating Officer, explained the rationale: "You don't build confidence in an orbital launch vehicle by waiting until the finished rocket is on the launchpad. You build it through thousands of decisions, measurements and tests along the way. This scaled-down XL system lets us test and validate the technology, subsystems and components together, understand how they perform and make improvements before scaling up to the full vehicle. Our approach is simple: test, learn, refine and test again, so that when Skyrora XL reaches the pad, we have confidence grounded in evidence."

Skyrora's Scottish Operations and Launch Licensing

Headquartered in Scotland, Skyrora designs, manufactures and tests launch vehicles and rocket engines from its facilities in Cumbernauld. The company is pursuing a broader launch programme alongside Skyrora XL, including the Skylark L suborbital vehicle, advanced propulsion systems and additive-manufacturing capabilities.

In 2025, Skyrora became the first UK-based launch vehicle manufacturer to receive a launch operator licence from the UK Civil Aviation Authority. That licence permits the company to conduct a suborbital launch of Skylark L from SaxaVord Spaceport in Unst, Shetland.

The company is working to establish reliable, sovereign access to space from British soil while strengthening Scotland and the UK's domestic space and advanced-manufacturing capabilities.

Next Steps in Vehicle Development

Following the Machrihanish trial, Skyrora's engineering team will continue to collate and analyse results before progressing to the second hot-fire test. This phased approach allows the company to validate technology and subsystems ahead of full-scale vehicle integration and eventual launch operations.
