Rocket Factory Augsburg (RFA)
Overview
German new-space launch provider developing RFA ONE, a 3-stage small-lift rocket sized at 1,300+ kg to LEO using nine in-house Helix engines (oxygen-rich staged combustion, kerosene/LOX). Spun out from OHB-affiliated Aerospace Propulsion Products in 2018; OHB SE remains the strategic shareholder. RFA also develops Orbital Stage, a re-ignitable kick stage / orbital tug for last-mile delivery, in-space servicing and constellation deployment. Inaugural orbital flight is targeted for summer 2026 from SaxaVord Spaceport (Shetland, UK), positioning RFA to perform the UK's first vertical orbital launch.
Moat: Only European new-space company building an oxygen-rich staged-combustion engine (Helix) — a higher-performance cycle than the gas-generator engines used by Isar's Aquila or Rocket Lab's Rutherford. Vertical integration (engine, stages, avionics) is reinforced by Aerospace Propulsion Products heritage. OHB SE's strategic shareholding gives an anchor European prime customer for payload integration. SaxaVord launch-pad exclusivity for the inaugural campaign and selection as anchor for the UK's first vertical orbital launch creates UK government alignment that competitors lack.

Oxygen-rich staged-combustion (ORSC) kerosene/LOX engine — first Western new-space ORSC engine to reach launch-vehicle integration
- Orbital Stage / kick stagedevelopment
Re-ignitable upper stage / space tug for last-mile orbit insertion, on-orbit servicing and constellation deployment
Government Contracts
| Agency | Program | Amount | Year | Source |
|---|---|---|---|---|
| ESA | Boost! commercial space transportation services contract | Up to €11M (Boost! ceiling) plus follow-on launcher demonstration support | 2024 | |

Near-term Catalysts
- Summer 2026
RFA ONE inaugural orbital test flight from SaxaVord Spaceport (Shetland, UK)
Would be the UK's first vertical orbital launch and would unlock the SaxaVord operational backlog and ESA Boost! follow-on contracts
- 2026 H1
Full-duration first-stage hot-fire repeat after Aug 2024 anomaly remediation
Critical regression test after the 18-month engine, tank-pressurisation and ground-procedure overhaul; gates pad re-entry
- 2026 Q2
Stage 1 + Stage 2 integration on relighted RFA pad at SaxaVord
First and second stages have already been delivered to SaxaVord — full vehicle stacking is the last operational milestone before launch
- 2026–2027
European Launcher Challenge (ELC) follow-on awards
RFA was a candidate for ELC tranche 2 funding alongside PLD Space, Isar and MaiaSpace; institutional anchor demand
Top Risks
- August 2024 SaxaVord stage-1 hot-fire anomaly destroyed a complete first stage and damaged the launch mount — a repeat would be catastrophic for the company's funding runway
- Pre-revenue, development-stage launcher with smaller balance sheet than Isar Aerospace (€400M+) and PLD Space (€380M+)
- Oxygen-rich staged combustion is technically ambitious; Helix qualification slips would compound program delays
- UK / SaxaVord regulatory approvals (CAA spaceport licence, UK ITAR-equivalent ECML) remain on the critical path
- ArianeGroup's MaiaSpace small launcher and Isar Spectrum already have hardware on the pad — RFA must demonstrate orbit before peers consolidate the European ELC pipeline
