Sustainment Support (Repair, Spares, and Engineering Services) for AN/GSM-397 Systems

The Government is seeking industry input to support the sustainment of the AN/GSM-397 Electronic Systems Test Set and its associated components used for the F-15 aircraft, requiring repair, manufacturing, sustaining engineering, software support, and program management services. While the Government holds formal design and document change authority, it lacks access to critical proprietary technical data including schematics, source code, interface documentation, and depot-level test procedures, making external contractor support essential to fulfill the requirement. Respondents are urged to propose Commercial-Off-The-Shelf solutions, modified COTS, Nondevelopmental Items, or commercial service models that can meet the technical needs without reliance on proprietary Government-held information. The solicitation number FA8517Repair23NSNs is posted as a presolicitation with a response deadline of August 19, 2026, and falls under NAICS code 811210 for repair and maintenance. All necessary materials, tooling, software, test equipment, and engineering services must be provided by the contractor. A list of targeted NSNs is provided in Attachment 1, though it remains subject to change, and no physical samples are available for evaluation. The effort is managed by the Air Force Life Cycle Management Center at Robins Air Force Base, Georgia, with primary point of contact Cedric Reese and secondary contact Steve Renfroe available for inquiries. There are no set-asides designated for this opportunity, and performance will occur at Warner Robins, Georgia.
