VANDENBERG SPACE FORCE BASE, Calif. - On the cusp of a new era in military space operations, Northrop Grumman has delivered 21 satellites to Vandenberg Space Force Base, California for launch, a significant step in advancing the Space Development Agency’s (SDA) Proliferated Warfighter Space Architecture (PWSA). These satellites, part of the Tranche 1 Transport Layer (T1TL), will provide secure and resilient communications for the warfighter and data transport for the PWSA Tracking Layer. Over the next six months, several dozen additional Northrop Grumman-built satellites for the PWSA will be launched into low Earth orbit (LEO), contributing to both the missile defense and data transport missions.
As a trusted innovator who’s delivered technologies that ensure American leadership in space for decades, Northrop Grumman is building on its unmatched experience building highly capable systems like the James Webb Space Telescope and the Arctic Satellite Broadband Mission. The company is applying this multi-orbit, end-to-end system expertise to produce resilient, proliferated architectures and manufacture satellites at speed and scale - an essential shift to meet the demands of modern warfighting.
The PWSA is a classic mission with a modern twist: a constellation of satellites designed to detect and track missiles and pass data around the world with almost no lag time. Northrop Grumman is combining its advanced technology and decades of mission expertise with the best commercially developed solutions to make high-volume manufacturing repeatable, affordable and resilient, and stay ahead of evolving global threats.
Northrop Grumman’s satellite production capabilities support a wide-scale rollout. Multiple PWSA contracts are underway, each delivering incremental improvements in mission capability. Dozens of satellites are fully integrated, with final checkouts in progress. The company’s robust supply chain management and diverse, growing supplier base has strengthened its ability to overcome challenges and efficiently deliver complex space systems.
By collaborating closely with the SDA, industry partners and suppliers, Northrop Grumman is advancing interoperable and modular solutions that meet SDA’s open architecture standards. These standards ensure seamless interoperability across satellites, payloads, and ground systems from multiple providers, enabling continuous, secure data flow across domains.
