General Dynamics Secures $400.4 Million Space Development Agency Contract for Next-Generation Military Space Network
General Dynamics Awarded $400.4 Million SDA Contract
General Dynamics Mission Systems has secured a $400.4 million contract from the Space Development Agency (SDA) to develop the ground segment for Tranche 3 of the Proliferated Warfighter Space Architecture (PWSA). The contract covers software development, testing, systems integration, and long-term operations and maintenance for the mission applications that will support the Pentagon's next-generation military satellite network.
The award is structured as a cost-plus contract and is expected to run through September 30, 2030. Initial funding includes $60.7 million in Fiscal Year 2026 Research, Development, Test and Evaluation (RDT&E) funds obligated at the time of award. Work will be carried out across facilities in Arizona, Washington, North Dakota, Alabama, and Virginia.
Building the Digital Backbone of Military Space Operations
Rather than building satellites, General Dynamics will develop the ground infrastructure that enables the constellation to operate. This includes mission software, command-and-control applications, systems integration, testing, and operational support required to manage the growing fleet of low-Earth orbit military satellites.
The ground segment acts as the central nervous system of the architecture, allowing military operators to control satellites, distribute sensor data, manage communications, and rapidly deliver information to commanders across multiple combat domains.
Supporting the Proliferated Warfighter Space Architecture
The Proliferated Warfighter Space Architecture (PWSA) is one of the Pentagon's most ambitious space modernization programs. Instead of relying on a small number of large satellites, the architecture deploys hundreds of smaller satellites in low Earth orbit to provide resilient communications, missile warning, missile tracking, and tactical data sharing.
This distributed approach is designed to improve survivability against anti-satellite threats while ensuring uninterrupted support for U.S. and allied military operations. The SDA is expanding Tranche 3 with additional satellite layers supporting missile warning and missile defense under broader initiatives such as Golden Dome for America.
General Dynamics Expands Its Space Portfolio
The latest award strengthens General Dynamics' position as a key provider of military space infrastructure. The company has previously supported SDA programs by developing ground management and integration systems, and the new contract builds on that experience with expanded software and operational responsibilities.
As the Department of Defense continues investing in resilient space-based networks, secure command systems, and integrated missile defense capabilities, General Dynamics is expected to play an increasingly important role in connecting satellites with warfighters across air, land, sea, cyber, and space domains.
