Darker bar: ahead of the other company on that measure.
Gravitics is a US space-hardware maker (Seattle) whose StarMax is a 400-cubic-meter station module (near half ISS volume in one launch) that pivoted toward aircraft-carriers-in-orbit for the Space Force: the Orbital Carrier pre-positioned deployment bays and the Viper OTV, sharing a 4m-form-factor manufacturing base. It won a SpaceWERX STRATFI (up to $60M combined government and private, April 2026) and has contracted flight demos with Rocket Lab and True Anomaly as program partners. It is pre-revenue (the STRATFI is matched funding, not revenue).

Millennium Space Systems designs and builds spacecraft platforms, including the Resolute mid-class platform and Epoch satellites, and is producing multiple spacecraft for government missions.
Darker bar: ahead of the other company on that measure.
Millennium Space Systems is a wholly owned Boeing subsidiary that designs, builds, tests and operates agile small-satellite and mid-class spacecraft for national-security and scientific missions. Its current ecosystem reach includes the U.S. Space Force as the customer for 12 MEO missile-warning and tracking vehicles, NASA for the TRACERS mission, SpaceX as the 2025 launch provider, and Boeing for EO/IR payload integration and expanded production. The key open question is whether Millennium and Boeing can deliver the Epoch 1 MEO vehicles on the revised 2026-27 schedule amid broader government findings of spacecraft-readiness and constellation schedule risk.
