The Tranche 2 Tracking Layer will enhance SDA’s capability to provide global, persistent indications, detection, warning, and tracking, of conventional and advanced missile threats, including hypersonic missile systems. Maxar Space Systems is proud to be a critical contributor to this part of the Proliferated Warfighter Space Architecture (PWSA). Collectively, the production of these platforms demonstrates Maxar Space Systems’ ability to develop and manufacture proliferated, low-Earth orbit (LEO) constellations that leverages the company’s Maxar 300 platform, deep experience, operational agility, and cost-efficiency to ensure customer mission requirements are achieved.

“Maxar Space Systems is excited to partner with L3Harris again on behalf of the Space Development Agency,” said Chris Johnson, CEO of Maxar Space Systems. “Our work on both the Tranche 1 and Tranche 2 Tracking Layers illustrates Maxar Space Systems’ ability to leverage our decades of deep commercial experience for new, complex programs on behalf of national security interests.”
