BREAKING: The Space Force is building a global missile-warning web in orbit designed to detect ballistic launches, follow maneuvering hypersonic weapons, and maintain their tracks across the planet.
That architecture has now cleared two major development milestones.
L3Harris (
$LHX) completed the preliminary design of 18 new low-Earth-orbit satellites for SDA’s Tranche 3 Tracking Layer. They will join a planned 72-satellite network split among L3Harris, Lockheed Martin, Northrop Grumman and
$RKLB, creating near-continuous coverage from LEO beginning in FY2029.
Higher above Earth, BAE Systems cleared the critical design review for a separate $1.2 billion system of 10 medium-orbit satellites and its ground command network, allowing the program to advance toward production.
The two layers are designed to work together: MEO sensors scan enormous regions of Earth, while the denser LEO network follows threats with greater speed and precision as they move across the globe.
This emerging architecture points toward a future in which the United States can detect a missile from space, maintain custody as it maneuvers, and rapidly feed that track into its defensive network.
