The U.S. Air Force intends to award a sole source firm-fixed-price contract to BAE Systems for the procurement of EPAWSS Group B Kits supporting the F-15EX program. The scope is limited to manufacturing and delivering physical hardware kits, including critical Line Replaceable Modules and expanded countermeasures capability. No specific budget amount, submission timeline, or performance location is mentioned in the notice. This is a pre-solicitation notice only, not a request for proposals, and the government will not reimburse response costs. Foreign participation at the prime contractor level is not permitted due to security requirements.
