The Space Development Agency (SDA) awarded $3.5 billion in contracts to four companies for a set of missile-tracking satellites. The contracts, announced Dec. 19, are for the Tracking Layer Tranche 3 segment of the Proliferated Warfighter Space Architecture (PWSA), a growing network of military satellites intended to provide faster, more resilient missile warning and tracking than legacy space systems. L3Harris Technologies, Lockheed Martin, Northrop Grumman and Rocket Lab will each build 18 satellites. Contract values range from $764 million for Northrop to $1.1 billion for Lockheed. The satellites are projected to launch in fiscal year 2029.
