# Starship V3's 3x payload improvement (35 to 100+ tons reusable to LEO) compresses the sub-$100/kg timeline by reducing per-kg cost even at similar per-flight cost

Starship V3's jump from ~35 metric tons (V2 reusable) to 100+ metric tons (V3 reusable) to LEO represents a 3x payload improvement in a single architecture revision. This is significant because it changes the cost-per-kg equation even if per-flight costs remain similar. If a V2 flight costs $X and delivers 35 tons, the per-kg cost is $X/35,000. If a V3 flight costs the same $X but delivers 100 tons, the per-kg cost drops to $X/100,000 — a 65% reduction through payload scaling alone, independent of reuse rate improvements. The source notes this is 'not incremental — it changes the economics of Starship payload deployment at scale.' IFT-12 (NET May 12, 2026) will be the first V3 flight test, validating whether the 100+ ton claim holds. The vehicle stands 408 feet tall (4 feet taller than V2) and uses Raptor 3 engines. The mission profile deliberately steps back from tower catch (both booster and ship target splashdown) to validate the new architecture before adding operational complexity. If validated, this makes propellant depots, commercial stations, and large telescope missions viable in single launches rather than requiring multiple V2 flights, directly affecting the sub-$100/kg trajectory that enables the broader space industrial economy.


## Supporting Evidence

**Source:** NASASpaceFlight V3 specifications, May 2026

Starship V3/Block 3 configuration launching on IFT-12 delivers ~3x payload capacity in full reuse mode compared to V2, with increased propellant capacity from taller vehicle dimensions and all-Raptor 3 engines. This is the first flight test of the hardware stack underlying the payload tripling projection.
