What Reaction Dynamics does

Reaction Dynamics (RDX) is a privately held Canadian aerospace and defense company founded in 2017 and headquartered in Longueuil, Quebec, that is developing a family of hybrid-propulsion launch vehicles and in-space propulsion subsystems centered on its patented RE-101 hybrid rocket engine. The engine combines solid fuel with a liquid oxidizer in a simplified architecture of roughly a dozen parts versus nearly 15,000 in conventional liquid-fueled engines, eliminating cryogenic handling and explosion risk while supporting stockpile-friendly, on-demand operations; the company also operates a Velo3D Sapphire laser powder bed fusion system for in-house additive manufacturing of nickel-based superalloy nozzles and combustion chambers in partnership with McGill University. Its product portfolio comprises the Aurora-8 two-stage orbital launcher (up to 250 kg to SSO, maiden orbital flight targeted 2028), the Aurora Suborbital demonstrator (maiden flight 2026), the Aurora-1 aeroballistic platform for hypersonic and microgravity test missions, and modular in-space satellite propulsion systems for orbit maintenance, collision avoidance and end-of-life deorbit.

The company is pre-revenue, with a quote-based commercial launch services model (first multi-launch contract signed with Galaxia at CANSEC in May 2025), a hardware sales stream planned for in-space propulsion modules, and a managed services angle into sovereign and allied defense launch under Canada's Defence Production Act — positioned as an ITAR-free provider. Capital structure is dominated by non-dilutive government funding: CAD $38M cumulative raised through a CAD $14M Series A (June 2025), CAD $8M Quebec grant, CAD $8.3M IDEaS Launch the North tranche, EUR 300K NATO DIANA Phase 2 award, CAD $1.5M Canadian Space Agency award, and a CAD $1M Draper Associates investment. Strategic partnerships with Maritime Launch Services (Spaceport Nova Scotia), Hanwha Ocean (MOU for strategic investment), DRDC, Space Machines Company, Maya HTT, McGill and Polytechnique Montreal anchor a domestic launch corridor and allied defense supply chain. The company has 1–10 employees and targets weekly launch cadence from containerized, mobile, low-footprint sites once operational.

Revenue model

1. Commercial launch services: Per-launch dedicated small-satellite delivery contracts to commercial constellation operators; first commercial contract signed with Galaxia at CANSEC in May 2025 (multi-launch), targeting satellites under 200 kg into LEO/SSO. Pre-revenue for orbital launch; suborbital flight planned first.
2. Government grants and public funding: Non-dilutive capital from Canadian federal and Quebec provincial governments including a CAD $10M Quebec grant, CAD $8.3M IDEaS Launch the North grant, CAD $8.3M Canadian Department of National Defence grant, plus EDC senior credit facility (to partner Maritime Launch Services) and NATO DIANA Phase 2 award (300,000 EUR).
3. Sale of in-space propulsion hardware and satellite mobility systems: Potential sales of modular in-space propulsion units for satellite operators needing high-density impulse for orbit maintenance, collision avoidance and end-of-life deorbit; positioned as a complementary revenue stream alongside launch services.
4. Defence and government launch services: Future sovereign and allied launch services to the Canadian Armed Forces, Department of National Defence, NORAD, NATO allies, and DRDC-aligned missions including responsive launch and reconstitution of space assets under Launch the North / IDEaS frameworks.

Core offering

Reaction Dynamics designs, manufactures and sells hybrid rocket launch vehicles and in-space propulsion hardware built around its patented RE-101 hybrid engine. Flagship offerings include the Aurora-8 two-stage orbital rocket (delivering up to ~250 kg payloads to LEO/SSO), the Aurora Suborbital demonstrator, the Aurora-1 aerobalistic test platform, and modular satellite propulsion subsystems. Revenue is generated through dedicated per-launch contracts, in-space propulsion hardware sales, and government/defense launch service agreements.

Product overview

Reaction Dynamics offers an integrated portfolio of launch and propulsion products built around a single patented hybrid propulsion technology. At the core is the RE-101 hybrid rocket engine, which solves a 90-year-old propulsion challenge and underpins the Aurora family of rockets: Aurora-8 (orbital, two-stage, 250 kg to SSO, orbital launch targeted 2028), Aurora Suborbital (maiden flight in 2026), and Aurora-1 (sub-orbital test platform for hypersonic and microgravity missions). Complementing these launchers, RDX markets in-space propulsion systems for satellite mobility (orbit raising, station-keeping, collision avoidance, deorbit). Reaction Dynamics is structured as a single product family with multiple variants and a complementary satellite subsystems business, all built on the same regenerative-cooled hybrid architecture that is ITAR-free and designed for stockpile-friendly, on-demand, responsive operations.

• Firefly Aerospace: Firefly operates the Alpha smallsat launcher and is developing the MLV medium-lift vehicle, directly competing with Aurora-8 in the dedicated small-sat launch market and increasingly in responsive defense launch.
• HyImpulse Technologies: HyImpulse is a European small-launch startup developing hybrid-propulsion rockets (SL1 and next-generation vehicles) — the most direct propulsion-technology peer to RDX's RE-101 hybrid architecture and Aurora family.
• NordSpace: NordSpace is a fellow Canadian small-launch startup and one of the three companies (with RDX and Canada Rocket Company) selected under Canada's $105M Launch the North initiative, directly competing for the same sovereign Canadian launch mandate.

Others
