This is a sole-source, firm-fixed-price repair requirement for U.S. Navy submarine Fly-By-Wire Ship Control System flight-critical components (SFCCs). Offerors must hold a valid CONFIDENTIAL security clearance and, if not the original manufacturer, provide authorization and OEM identification. The contractor has 45 days after receiving carcasses to complete teardown and evaluation and submit a firm-fixed-price repair quote, with a requested repair turnaround time of 180 days. A one-year warranty from date of delivery applies, along with stringent quality, traceability, and configuration control requirements. Performance occurs at the contractor’s facility, with government inspection at source and no change of location without authorization.
