Named in May 2024, via UK subsidiary Space Engine Systems Ltd, as one of 90 suppliers eligible to bid under the UK MoD's Hypersonic Technologies and Capability Development Framework. spaceq.ca
Operates a design and production facility plus airside operations in Edmonton, Alberta, and an airside building at Newquay Airport, Cornwall. spaceenginesystems.com
AIAA's Aerospace America reported that SES tested near-full-scale versions of its complete DASS GNX turbo-ramjet in July and August 2024, including early destruction testing. aerospaceamerica.aiaa.org
In July-August 2025 at its Villeneuve Airport facility, the precooler-enabled turbojet demonstrated performance to Mach 3 and full-scale ramjet tests sustained hydrogen combustion up to 30 seconds. aerospaceamerica.aiaa.org
Mach 5 remains simulation only: the 2025 ground tests demonstrated Mach 3 on the turbojet, with simulations extending to Mach 5. No SES vehicle has flown. aerospaceamerica.aiaa.org
States it is "ISO 9001 and AS9100D certified" and registered with Canada's Controlled Goods Program. spaceenginesystems.com
Its 51-200 headcount band is self-declared on LinkedIn, where only about ten members are associated with the company. Treat the band as the company's own claim rather than a measured figure. linkedin.com
Its own site gives two different HELLO-1 payload figures to low Earth orbit, 1,000 kg on one page and 550 kg on another, so the figure here should be read as unsettled. spaceenginesystems.com
Products Space Engine Systems publishes on its own site. Each card links to the page it was taken from.
Turbo-ramjet engine
Precooled air-breathing turbo-ramjet: an afterburning turbojet from zero to Mach 3 and a ramjet from Mach 3 to Mach 5, rated 88.9 kN sea-level static thrust on multiple fuels. Ground-tested hardware; no flight.
Learn moreHypersonic demonstrator aircraft
Piloted hypersonic demonstrator, with an uncrewed option, designed to take off from a runway, cruise at Mach 5 between 28 and 32 km and glide back to base. Engine integration was under way as of October 2024; it has not flown.
Learn moreReusable launch vehicle
Reusable horizontal-takeoff vehicle combining DASS GNX with a rocket engine for a suborbital trajectory to 100 km, and 1,000 kg to low Earth orbit via a transfer vehicle. Design stage; the site says a first test-flight schedule will be announced, with no date.
