## What project 650013 buys

When KC-46A procurement completes, the Air Force will maintain continuous recapitalization of the KC-135 fleet by procuring additional KC-46A tanker aircraft under the KC-46A Production Extension (PEx) project. The Air Force plans to use the KC-46A Capability Production Document as the most affordable requirements basis for Tanker Production Extension. The The KC-46A PEx program funding supports development of acquisition documentation, detailed acquisition plans, Request for Proposal (RFP) contracting activities, assessment and mitigation of risks and issues, and other studies and analysis. Funding includes efforts to define and mitigate Diminishing Manufacturing Sources & Materiel Shortages (DMSMS) and obsolescence issues in preparation for aircraft procurement.​ The KC-46A PEx effort ensures tanker availability for the warfighter and supports the Air Force's assessment and development of tanker requirements for the next Tanker Recapitalization program. This requirement supports performance of a full financial audit as required by title 10 U.S.C. Chapter 9A, Sec 240-D. This program element included all necessary expenses required to manage, execute, and deliver weapon system capability. The use of such program funds would be in addition to the civilian pay expenses budgeted in program elements 0605829F, 0605831F, 0605833F, and 0605898F.

**R-3 lines of work:** Product Development; Support.
