// OVERVIEW

The Vanguard OTV is last-mile logistics for orbit: a reusable, refuelable tug that picks up payloads at a rideshare drop-off and delivers them to their final orbit — LEO, GEO, or cislunar.

Refueling at a Drift Node turns a single vehicle into a persistent delivery service, decoupling the destination orbit from the launch manifest.
