What the Air Force is buying and why it matters

The Department of Defense, specifically the US Air Force, is seeking solutions for the KC-135 Center Console Refresh (CCR) program. This involves updating the KC-135 Refueling Tanker aircraft with new Fuel Systems, Flight Display Systems, and Flight Computers. The goal is to address obsolescence issues and improve these systems, including the addition of autothrottle systems.

This is a significant long-term opportunity, with an anticipated contract period from July 2028 to June 2038. The contract structure includes a Cost-Plus Incentive Fee (CPIF) for Engineering and Manufacturing Development (EMD) and Firm Fixed Price (FFP) for Production and Deployment (P&D). It will be a single-award indefinite delivery/quantity contract.

Key dates and what happens at the deadline

The solicitation was published on August 24, 2026. The deadline for proposal submissions is October 15, 2026, at 5:00 PM ET. All proposals must be submitted by this time.

Remember that the solicitation and any amendments must be signed and included with your proposal submission. The Air Force has released editable PDF versions of these documents.

Who this opportunity suits

This opportunity is suitable for companies with expertise in aircraft fuel systems, flight display systems, flight computers, and autothrottle systems. Given the nature of the work, experience with military aircraft and complex integration projects will be beneficial.

Small businesses interested in this equipment category should note that specific security clearances are required to access detailed solicitation documents. Your company will need an active DD2345 on file through the Joint Certification Program (JCP) website.

How to respond to this solicitation

To access the solicitation documents, you must have a role assigned in SAM.gov. Once your role is assigned, submit a request to view the documents and ensure you include your company’s CAGE code. Failure to provide the CAGE code will delay your access request.

Access to controlled documents will only be granted if your company has an active DD2345 on file through the JCP website. If your DD2345 is not found or is inactive, it must be updated and active before access can be approved. Government personnel cannot assist with assigning SAM.gov roles or DD2345 issues; you will need to contact SAM.gov or the JCP for assistance.

Practical tips for preparing a competitive response

Thoroughly review all solicitation documents, including any amendments, to understand the full scope of work and requirements. Pay close attention to the technical specifications for the fuel system, flight display system, flight computer, and autothrottle integration.

Since this is a long-term contract with different pricing structures for EMD and P&D, ensure your cost proposal is meticulously detailed and aligns with the specified contract types. Clearly articulate your innovative ideas for improving the systems and enabling future supportability and growth, as the Air Force is looking for turn-key solutions.

Given the requirement for an active DD2345 and SAM.gov roles, start the process of verifying and updating these credentials immediately. Delays in obtaining access to controlled documents can significantly impact your ability to prepare a timely and complete proposal.
