# Starship V3's tripled payload capacity (>100 MT vs V2's 35 MT) lowers the $100/kg launch cost threshold entry point from 6+ reuse cycles to 2-3 reuse cycles

Starship V3's >100 MT reusable payload to LEO represents a 3x increase over V2's ~35 MT capacity. When this payload multiplier is applied to the KB's existing V2 cost projections, the economics fundamentally shift: V3 single-use drops to ~$900/kg (vs V2's higher baseline), and critically, V3 crosses the $100/kg threshold at approximately 2-3 reuse cycles rather than V2's 6+ cycles. At 6 reuse cycles, V3 achieves $25-30/kg (vs V2's $78-94/kg). This is not merely an incremental improvement but a structural change in when cost thresholds become accessible. The $100/kg threshold matters because it's the feasibility gate for gigawatt-scale orbital compute (per Google's Project Suncatcher analysis) and multiple ISRU economics models. V3's lower threshold entry point means these applications become viable 2-3 years earlier in calendar time, assuming comparable reuse cadence to V2. The Raptor 3 engine being 4x cheaper to manufacture than Raptor 1 (SpaceX reported) compounds this advantage. However, this timeline acceleration is theoretical and depends entirely on achieving the reuse cycles, which leads to the investigation bottleneck constraint.


## Supporting Evidence

**Source:** NASASpaceFlight, April 29, 2026

Starship V3 configuration debuts with IFT-12, featuring taller Ship and Super Heavy Booster with increased propellant capacity and full Raptor 3 engine suite. Payload capacity increases approximately 3x versus Starship V2 in full reuse mode. Both flight vehicles (Booster 19 and Ship 39) completed full static fires April 15-16, 2026, validating ground-test readiness of the V3 configuration before maiden flight.
