Notice of Intent to Sole Source: SDA Tranche 3 (T3) Ground Segment Development (GSD)

The Space Development Agency (SDA) intends to award a sole-source contract to General Dynamics Mission Systems (GDMS) for the Proliferated Warfighter Space Architecture (PWSA) Tranche 3 (T3) Ground Segment Development (GSD) effort. The contract will include systems engineering, development and deployment, operations and maintenance of Tranche 1 and Tranche 2 ground entry points, and operations and maintenance of ground segment capabilities. The T3 GSD effort will leverage the existing platform/framework, development, test, and operations environments, and mission applications developed under the current GDMS awarded PWSA Ground Management and Integration (GMI) contract. • The contract is anticipated to be awarded in August 2026. • The contract will consist of a four-year base period with six one-year option periods for O&M activities. • The SDA has solicited industry inputs through a Broad Agency Announcement to identify approaches to develop and transition from the existing PWSA GS framework/platform and mission applications. • Any responses to this notice must demonstrate clear and convincing evidence that competition would be advantageous to the Government and would not hinder the timeline or mission objectives of the T3 GSD effort.
