Contract Awards Accelerate Golden Dome Satellite Development
The Space Development Agency awarded $1.75B to L3Harris ($955M) and Sierra Space ($798M) for 36 satellites to enhance the Golden Dome missile defense system. These satellites, part of Tranche 3, will support tracking and defense capabilities in low-Earth orbit, with launches expected in 2028. The U.S. Space Force will operate and sustain them. The awards align with SDA's plans for global missile defense coverage.
