The U.S. Air Force is seeking a contractor to provide technical expertise and engineering staff for F-15 avionics hardware and software updates, production support, and modifications to improve reliability and maintainability. The contract will be a Cost-Plus Fixed Fee, IDIQ with a 12-month basic ordering period and two additional 12-month ordering periods, with performance anticipated to begin September 2026 for a total of three years. The government intends to use other than full and open competition, citing Northrop Grumman Systems Corporation as the only source capable of meeting the requirement without unacceptable delays. The F-15 fleet’s remaining life cycle is currently scheduled through 2045. No specific budget amount or performance location is mentioned.
