DASS GNX
The Core of Next-Gen Hypersonics
The DASS-GNX is an advanced air-breathing turbo-ramjet engine designed for hypersonic flight and rapid reusability. Ground-proven with airworthiness certification expected in 2025, it powers both defence and space platforms, enabling sustained high-speed operations without reliance on traditional rockets. This trade-secret propulsion system reduces cost, increases efficiency, and accelerates mission readiness for both tactical and launch applications.

Hello-1
Hello-1 is a reusable hypersonic spaceplane providing high-frequency, low-cost orbital access. Combining air-breathing turbo-ramjet propulsion with rocket-assisted insertion, it offers a flexible, rapid-response alternative to traditional rockets. Operating from Spaceport Cornwall and additional global sites, it cuts costs and turnaround times by eliminating single-use boosters and complex infrastructure.
With unmatched reusability, Hello-1 enables NewSpace ventures, research, and defence applications to deploy payloads faster and cheaper. Its horizontal takeoff and landing (HTOL) capability supports satellite deployments, suborbital research, and in-orbit demonstrations, strengthening the UK’s sovereign launch capabilities and making space more accessible.
