Space Forge
Overview
Manufactures ultra-high-performance semiconductor substrates in the vacuum/microgravity of LEO aboard returnable ForgeStar satellites, selling the materials — not the satellites — to terrestrial chip customers.
Moat: Owns the only free-flying commercial semiconductor manufacturing tool ever operated in orbit, plus the proprietary Pridwen deployable heat shield for material return — a vertically integrated make-and-return loop no competitor has demonstrated.

Key Products
- ForgeStar-1operational
Launched and established in-orbit communications; in December 2025 generated microwave-induced plasma at up to ~1,000°C in LEO, a world first for a free-flying commercial semiconductor tool. Never designed to return — slated for controlled deorbit during 2026.
First flight: 2025-06-27
- ForgeStar-2development
Adds the Pridwen heat shield for the company's first attempt at material return.
- Pridwen heat shielddevelopment
Deployable heat shield, zero-gravity deployment tested October 2025.
Near-term Catalysts
- 2026
ForgeStar-1 controlled deorbit
Validates end-of-life and re-entry models feeding directly into Pridwen.
- 2026-2027
ForgeStar-2 build and launch
The first attempt to physically return space-manufactured semiconductor material; the entire business thesis hinges on it.
Top Risks
- Return is unproven — every revenue model depends on Pridwen surviving re-entry with intact product, never yet demonstrated end-to-end.
- Space-grown substrates must beat terrestrial fabs on performance by enough to justify launch and recovery cost.
- Capital-intensive, pre-revenue path requiring repeated large raises in a UK market shaken by Orbex's 2026 administration.
