Overview
Cyclone‑4M is a medium‑lift launch vehicle under development by the Ukrainian aerospace organizations Yuzhnoye Design Office and the National Space Facilities Control and Test Center (NSFCT), in partnership with the Canadian company Maritime Launch Services Ltd. (MLS). The vehicle is intended to provide commercial launch services for small‑to‑medium communication satellites to low‑ Earth orbit (LEO) and sun‑synchronous orbit (SSO).
Development History
The Cyclone‑4M derives its heritage from the Soviet‑era Tsyklon (Cyclone) family of launchers, which were originally designed by Yuzhnoye for orbital insertion of military and scientific payloads. After the dissolution of the USSR, Yuzhnoye pursued modernization of the Tsyklon lineage, resulting in the Cyclone‑4M concept. In 2016, MLS announced a launch services agreement with Yuzhnoye to operate the vehicle from a newly planned spaceport at Canso, Nova Scotia, Canada. Since then, the programme has progressed through design reviews, subsystem testing, and the construction of a launch complex at the Canso site.
Technical Description
| Parameter | Details |
|---|---|
| Configuration | Two‑stage launch vehicle |
| First stage | Liquid‑propellant engine (RD‑843) burning liquid oxygen (LOX) and kerosene (RP‑1). The engine is derived from the RD‑861 family used on earlier Cyclone rockets, modified for higher thrust and re‑ignition capability. |
| Second stage | Solid‑propellant motor (design based on the Ukrainian “KVD‑1” motor). |
| Launch mass | Approximately 120 t (estimated) |
| Payload capacity | Up to 5 t to a 700 km circular LEO, or ~3 t to a 800 km SSO (values based on publicly released performance estimates). |
| Dimensions | Length ≈ 30 m; diameter ≈ 3.35 m (consistent with the Cyclone family). |
| Recovery | No stage recovery; all stages are expendable. |
| Guidance & control | Inertial navigation system with autonomous flight termination capability. |
Launch Site
The primary launch site designated for Cyclone‑4M operations is the Canso Spaceport (also referred to as the “Nova Scotia Spaceport”) on the eastern coast of Canada. The site features a coastal launch pad with ocean‑based safety corridors, enabling launches over sparsely populated regions.
Program Status
As of mid‑2024, Cyclone‑4M remains in the pre‑operational phase. Structural and propulsion subsystem tests have been completed, and the Canso launch infrastructure is undergoing final certification. The programme has not yet conducted a full‑vehicle flight; a maiden launch has been tentatively scheduled for the early 2025 timeframe, subject to regulatory approval and final vehicle integration.
International Context
Cyclone‑4M is part of a broader trend of new medium‑lift launchers emerging from former Soviet design bureaus, seeking to capture a growing commercial market for dedicated satellite launches. Its development reflects Ukraine’s ongoing efforts to maintain a presence in the global launch industry and Canada’s interest in establishing an indigenous launch capability.
