## Supporting Evidence

**Source:** Starship V3 cost projections and Suncatcher threshold analysis, April 2026

Starship V3 with tripled payload capacity and Raptor 3 cost reduction makes the $200/kg threshold achievable within 2-3 years of routine operations according to analyst projections. V3 economics at projected high-cadence operations approach this threshold, validating that the Suncatcher threshold is not just theoretically sound but practically reachable within the current Starship development roadmap.

## Supporting Evidence

**Source:** Basenor.com analysis connecting V3 payload economics to orbital data center thresholds, April 2026

Starship V3 economics analysis explicitly cites the $200/kg Project Suncatcher threshold as now achievable within 2-3 years of routine V3 operations, validating that this threshold remains the relevant target for orbital data center viability and that V3 represents the launch vehicle generation that can reach it.

# Google's Project Suncatcher research identifies $200/kg launch cost as the enabling threshold for gigawatt-scale orbital AI compute constellations, validating the tier-specific model where constellation-scale ODC requires Starship-class economics while proof-of-concept operates on Falcon 9

Google's Project Suncatcher research paper explicitly states that 'launch costs could drop below $200 per kilogram by the mid-2030s' as the enabling cost threshold for gigawatt-scale orbital compute constellations. This validates the tier-specific deployment model: Google is launching a 2-satellite proof-of-concept in early 2027 using Falcon 9 (current cost ~$1,500-3,000/kg for dedicated launches), while explicitly stating that constellation-scale deployment requires approximately 10x further cost reduction to ~$200/kg by the mid-2030s. Sundar Pichai's framing of 'a decade away from a new normal of extraterrestrial data centers' aligns with this mid-2030s Starship-class economics timeline. The technical architecture (81-satellite clusters in 1km arrays, gigawatt-scale vision) represents the constellation tier, while the 2027 test represents the proof-of-concept tier. This is the first major hyperscaler to publish a specific cost threshold validation, moving the tier-specific model from theoretical framework to industry planning assumption.

## Extending Evidence

**Source:** Basenor, April 2026 - Starship V3 cost projections vs. Google feasibility study

Starship V3's projected $78-94/kg at 6 reuse cycles is already below the $200/kg Google threshold for competitive ODC cost-competitiveness. This suggests the threshold may be reached sooner than anticipated, though commercial pricing vs. technical cost projections remain distinct.
