How to bid on the KC-135 Center Console Refresh for the DEPT of Defense

What the Air Force is buying and why it matters

The U.S. Air Force is seeking proposals for the KC-135 Center Console Refresh (CCR) program. This initiative addresses critical obsolescence issues in the KC-135 Refueling Tanker aircraft. The goal is to replace obsolete Fuel System, Flight Display System, and Flight Computer equipment, and to add autothrottle systems. The Air Force is looking for innovative, turn-key solutions that improve these systems and allow for future growth and adaptability.

This contract is significant for vendors specializing in aerospace engineering, manufacturing, and system integration. It covers engineering and manufacturing development (EMD), production, and deployment (P&D) under a single award indefinite delivery/quantity contract. The anticipated contract includes a 48-month base period and six one-year option periods, with a projected performance from July 2028 to June 2038.

Key dates and what happens at the deadline

Proposals for the KC-135 Center Console Refresh are due by November 02, 2026, at 1:00 PM ET (which is 12:00 PM CST). All required solicitation and amendment documents must be signed and included with your proposal submission.

It is crucial to submit your proposal on time. Late submissions are generally not considered. Ensure all necessary access to controlled documents is obtained well in advance of the deadline, as this process requires specific company registrations.

Who this opportunity suits

This opportunity is suitable for companies with expertise in aerospace engineering, avionics, flight control systems, and fuel systems. Firms capable of providing turn-key solutions for complex aircraft system upgrades, including design, development, production, and deployment, will find this solicitation relevant.

The contract structure includes a Cost-Plus Incentive Fee (CPIF) for the EMD phase and Firm Fixed Price (FFP) for Production and Deployment. This structure may appeal to companies comfortable with both cost-reimbursement and fixed-price contract types.

How to respond to this solicitation

To access the solicitation documents, you must first have a role assigned in SAM.gov. Once your role is assigned, you can submit a request to view the controlled documents. It is essential to include your company’s CAGE code with your access request; failure to do so will cause delays.

Access to controlled documents will only be granted if your company has an active DD2345 on file through the Joint Certification Program (JCP) website. If your DD2345 is not found or is inactive, it must be updated and active before your access request can be approved. Be aware that government personnel cannot assist with assigning roles in SAM.gov or with DD2345 updates; you will need to contact SAM.gov or the JCP for assistance with those processes.

Tips for preparing a competitive response

Carefully review all amendments to the solicitation. Amendment 04, for example, made minor corrections to the Statement of Work and pricing matrixes. Ensure your proposal reflects the most current requirements and pricing structures.

Given the focus on obsolescence and future growth, highlight your company's innovative approaches and proven track record in modernizing complex aircraft systems. Emphasize your ability to provide turn-key solutions that are supportable and adaptable for future upgrades.

Pay close attention to the contract type for each phase: CPIF for EMD and FFP for Production and Deployment. Your pricing proposal should clearly delineate costs and incentives according to these structures. Ensure all required forms, including the signed solicitation and amendments, are included in your submission.
