# Orbital data center deployment follows a three-tier launch vehicle activation sequence (rideshare → dedicated → constellation) where each tier unlocks an order-of-magnitude increase in compute scale

Starcloud's $170M Series A roadmap provides direct evidence for tier-specific launch cost activation in orbital data centers. The company structured its entire development path around three distinct launch vehicle classes: Starcloud-1 (Falcon 9 rideshare, 60kg SmallSat, proof-of-concept), Starcloud-2 (Falcon 9 dedicated, 100x power increase, first commercial-scale radiative cooling test), and Starcloud-3 (Starship, 88,000-satellite constellation targeting GW-scale compute for hyperscalers like OpenAI). This is not gradual scaling but discrete architectural jumps tied to vehicle economics. The rideshare tier proves technical feasibility (first AI workload in orbit, November 2025). The dedicated tier tests commercial-scale thermal systems (largest commercial deployable radiator). The Starship tier enables constellation economics—but notably has no timeline, indicating the company treats Starship-class economics as necessary but not yet achievable. This matches the tier-specific threshold model: each launch cost regime unlocks a qualitatively different business model, not just more of the same.
