This notice revises SDA-SN-25-0024 The Space Development Agency (SDA) intends to award a sole-source contract to General Dynamics Mission Systems (GDMS; CAGE 1VPN8), for the Proliferated Warfighter Space Architecture (PWSA) Tranche 3 (T3) Ground Segment Development (GSD) effort. GDMS shall provide the systems engineering (SE), development and deployment, operations and maintenance (O&M) of Tranche 1 and Tranche 2...
View moreA sole source award to GDMS is justified in accordance with 10 U.S.C. § 2304(d)(l)(B), as implemented by FAR 6.302-l(a)(2)(ll), as it is likely that award to any other source would result in substantial duplication of cost to the Government that is not expected to be recovered through competition and unacceptable delays in fulfilling the agency's requirements. An organizational assessment of pre-existing Conflict of Interest (COI) exclusions, aligned with the GMI contract award, also supports the determination of sole source award to GDMS. The planned cost-plus contract is anticipated to be awarded in August 2026. The contract will consist of a four (4)-year base period with six (6) one-year option periods for O&M activities. 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 to enable a future open competition of the Ground Segment to multiple vendors/performers.
This notice of intent is not a request for competitive proposals and no competitive solicitation will be issued. 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. Any response shall include the following information: 1) the business/demographic information showing responsibility and qualification in accordance with FAR Part 9; 2) specific exception to the intent to procure on a sole source basis; 3) technical data showing the capabilities of the respondent to perform the work listed above. The response must provide clear, convincing and unambiguous evidence to substantiate the capability of the respondent to provide the required services as listed above. A request for documentation or additional information or submissions that only ask questions will not be considered an affirmative response to this notice.
The determination not to compete this proposed contract action is solely within the discretion of the Government. Any responses received will be assessed for the purpose of determining a compelling basis to conduct a competitive procurement. The Government will not be responsible for any costs incurred by responding to this notice. Responses, to include capability statements, proposals or quotations, shall be sent via email only to [email protected] (cc: [email protected]), no later than 17 April 2026, at 1:00 PM PT. It is the responsibility of the respondent to contact the Government to confirm receipt prior to the above due date and time. Responses submitted after this deadline will not be addressed.
The Space Development Agency (SDA), under the Department of the Air Force, 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. This special notice, identified as SDA-SN-26-0010, outlines requirements for systems engineering, development, deployment, and operations and maintenance (O&M) of Tranche 1 and Tranche 2 ground entry points. The effort includes integrating ground segment capabilities to support T3 Tracking space vehicle missions and ensuring interoperability within the PWSA architecture. The contractor will leverage existing frameworks, test environments, and mission applications from the current Ground Management and Integration (GMI) software baseline and continuous integration/delivery pipeline to meet aggressive launch readiness timelines.
The planned cost-plus contract is anticipated for award in August 2026, featuring a four-year base period and six one-year option periods for O&M activities. This procurement is classified under NAICS 541715 Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology) and PSC AC33 National Defense R&D Services; Defense-Related Activities; Experimental Development. The SDA has justified the sole-source selection based on the determination that award to any other source would result in substantial duplication of costs and unacceptable schedule delays. Additionally, an assessment of pre-existing conflict of interest exclusions aligned with the GMI contract supports the selection of GDMS.
While this is not a request for competitive proposals, the government will consider responses that provide clear and convincing evidence that a competitive procurement would be advantageous and would not hinder mission objectives. Submissions must include business qualifications, specific exceptions to the sole-source intent, and technical data substantiating the respondent's capability to perform the work. All responses must be submitted via email to the primary point of contact, Beatriz Estrada, by April 17, 2026, at 1:00 PM PT. The government retains sole discretion in determining whether to conduct a competitive procurement based on the information received.
