DASS Hypersonic Engines
Powering Hypersonic Realities
The DASS Engine family represents a breakthrough in air-breathing hypersonic propulsion, developed entirely in-house by Space Engine Systems (SES). These engines are designed for high-speed, agile aerospace platforms, enabling hypersonic flight, orbital access, and rapid point-to-point transport.
SES’s DASS-GNX and DASS-GNX-M engines provide scalable, fuel-efficient, and high-performance solutions for hypersonic drones, spaceplanes, and next-generation aerospace vehicles.
DASS-GNX
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.
