US Space Force Accelerates Global Missile Defense with Massive Satellite Expansion
The U.S. Space Force is significantly enhancing its space-based missile defense capabilities by contracting L3Harris Technologies and Sierra Space for an additional 36 advanced tracking satellites. Valued at $1.75 billion, these spacecraft are integral to the "Golden Dome" initiative and will bolster the Proliferated Warfighter Space Architecture's Tranche 3 Tracking Layer, providing unparalleled global surveillance against evolving missile threats by 2028. This expansion builds upon previous tranches, creating a robust, low Earth orbit constellation designed for real-time detection and tracking of hypersonic and ballistic missiles.
