Proliferated low-Earth orbit (pLEO) architectures - constellations of hundreds of smaller, lower-cost satellites orbiting earth close to the atmosphere - add a resiliency layer to our current array of on-orbit systems and can better target hypersonic missiles maneuvering in flight. In support of Space Development Agency (SDA), Northrop Grumman is a leader in the effort to rapidly field a global pLEO architecture of data transport and missile warning/missile tracking satellites and the powerful ground systems that stitch it all together.

To help SDA make this complex architecture a reality, Northrop Grumman is combining its advanced technology and decades of mission expertise with the best commercially developed technology from partners ready today to produce with speed and at scale.
