Golden Dome Space-Based Interceptor Layer
Space Force program developing space-based interceptor prototypes for the Golden Dome missile defense architecture.
The Golden Dome space-based interceptor (SBI) layer is a U.S. Space Force effort to develop space-based interceptor prototypes as part of the broader Golden Dome missile defense architecture, targeting a 2028 demonstration. Split out as its own program record from a combined 'Space Warfighting Architecture' entry, since its budget and participant set are materially different from SDA's Proliferated Warfighter Space Architecture (see space-warfighting).
