Solicitation FA8105_CCR_Rev2 (KC-135 Center Console Refresh Revision 2; the documents number it FA810526RB001): the Air Force Life Cycle Management Center (AFLCMC) at Tinker AFB, OK wants a contractor to replace the KC-135 tanker's fuel system, flight display system and flight computer, and add autothrottle. It is one award with a 48-month development base plus six one-year options, projected July 2028 to June 2038. The response due date is November 16, 2026, 12:00 PM Central.
Who can bid
- Active DD 2345 (Military Critical Technical Data Agreement) on file with the Joint Certification Program (JCP) to get access to the controlled documents, which include the statement of work and system requirements
- A SAM.gov role and your company's CAGE code on the request to view the controlled documents
- Current CMMC Level 2 (Self) status and affirmation in SPRS before award for each system that handles federal contract information or controlled unclassified information (Amendment 0001 lowered this from Level 2 certified by a third-party assessor)
How to submit: Electronic proposal (Section L lists Electronic Offers); the exact submission method is in part of Section L that was not in the text provided. What to include is under Full summary below. Check the solicitation's instructions on SAM.gov.
Things to watch (7)
From the version posted Oct 23, 2026.
- Serious: Large cost-type development program with business-system reviews. Cost-plus-incentive-fee development brings cost realism review, cost accounting standards and accounting system checks, which most small businesses cannot meet without a prime partner.
- Serious: Statement of work and system requirements are controlled. You cannot read the statement of work, system requirements or contract data list until your company has a SAM.gov role, a CAGE code and an active DD 2345, so a bid cannot be scoped before that.
- Serious: CMMC status must be in place before award. A bidder without the required CMMC Level 2 (Self) status in SPRS is not eligible for award, and the proposal must list the unique identifiers.
Show all 7Show fewer
- Worth checking: All amendments must be signed and returned. Eight amendments have been issued, and a proposal without them signed can be rejected.
- Worth checking: Price evaluation preference for HUBZone firms. The solicitation as first issued adds 10 percent to the price of offers that are not from HUBZone small businesses (and some small business offers), which can make a non-HUBZone price less competitive.
- Worth checking: Earned value management required. Earned value management (a way of tracking cost and schedule progress) was added by amendment, which means more reporting and a compliant system.
- Minor: Pricing workbooks are detailed and still changing. Amendment 08 changed the units of CLINs 0001 and 0003 and updated the Excel pricing workbooks, so use only the latest versions (Attachment 3A UPDATED7, 3B UPDATED5).
