The brief

Analyst view
  • The US Space Force was established as the sixth branch of the US Armed Forces in December 2019.
  • Golden Dome is a $185 billion integrated missile defense architecture with space-based interceptors, radars, and command centers.
  • April 2026: $3.2 billion awarded to 12 contractors for interceptor prototypes. Demos 2028; full capability 2035.

Technical approach

As reported
Space-based constellation

Proliferated low-Earth orbit satellites

Small, inexpensive satellites in low-Earth orbit carry kinetic interceptors for boost, midcourse, and glide-phase engagement.

Kill vehicles

Kinetic impact interceptors

Multiple hit-to-kill vehicles per satellite use direct impact to destroy missiles. No nuclear warheads; reduces debris.

Integrated architecture

Tied to ground sensors and command

Satellites work with ground radars, command centers, and Homeland Defense systems for detection and fire control.
