The U.S. Air Force is contemplating a firm fixed-price requirements contract for the repair of the KC-135 Multipoint Refueling System, with performance at Tinker AFB, Oklahoma. The contract includes a base year plus four one-year options and covers a wide range of items such as fuel door assemblies, hose drum assemblies, and flight refueling pods. This is a sole-source requirement to Cobham Mission Systems, and qualification requirements apply, meaning award cannot be delayed for additional source approval. No budget amount is specified in the notice. All responsible sources may submit a capability statement for consideration.
