Part of the SDA's eight-satellite Tranche 0 Tracking Layer, deployed to validate the concept of distributed, resilient missile warning from low Earth orbit ahead of full operational deployment. As of December 2025, the SDA announced $3.5 billion in Tranche 3 Tracking Layer contracts for 72 additional satellites — a scale increase that traces its origins directly back to demonstration missions like WILDFIRE 9.
