# Starcloud-3 cost competitiveness requires $500/kg launch cost threshold

Starcloud CEO Philip Johnston provided the first explicit industry activation threshold for orbital data centers: $500/kg launch cost. He stated that Starcloud-3, their 200 kW, 3-tonne spacecraft designed for SpaceX's Starship deployment system, would be 'cost-competitive with terrestrial data centers' at this price point, targeting $0.05/kWh. This is conditional on commercial Starship access, which Johnston notes 'isn't expected until 2028-2029.' Current commercial Starship pricing is approximately $600/kg (per Voyager Technologies filing), meaning the gap is real but narrow—potentially clearable in 2027-2028 with higher reuse cadence. This represents the most specific and authoritative data point connecting ODC cost competitiveness to a launch cost threshold, directly instantiating the general claim that each launch cost milestone activates a new industry. The $100/kg gap ($600 current vs. $500 required) represents the final barrier to ODC industry activation at scale.
