How we built the list


We combined public data, product sheets, conference materials, and Procureezy’s discovery signals. We prioritize: flight heritage, certs and audits, production capacity, and clarity on export controls. If you are a supplier and want to be included or updated, contact us.
‍
Selection criteria (what buyers care about)
Capability and envelope: thrust range, Isp, power, propellant, total impulse.
Form factor fit: CubeSat class compatibility, volume, mounting interfaces.
Quality & compliance: AS9100/EN9100, ECSS, REACH/ROHS, ITAR/EAR notes.
Operations: average lead time, MOQ, integration and acceptance test options.
Reliability signals: flight heritage, on-time delivery, NC trends.

FAQ


Which propulsion technologies are most available in Europe today
Hall-effect and iodine-based electric systems are widely available. FEEP and electrospray are common for nanosats. Green monopropellant options exist if you are replacing hydrazine.

‍How long do propulsion deliveries typically take
Plan for 3 to 12 months depending on capability, qualification status, and vendor backlog. Ask for a capacity statement in the quote.

‍What certifications should I look for
AS9100 or EN9100, ECSS process alignment, and clear statements on REACH or ROHS. Request export classification letters early.

‍Can I use multiple vendors on one mission
Yes. Many teams split awards for risk reduction or source PPUs and tanks from partners recommended by the primary vendor.
