NAVAIR/PMA-265 is conducting market research to identify industry capability and facility capacity to provide supplemental or secondary turnkey Service Life Modification capacity for F/A-18E/F and EA-18G aircraft starting in FY29. The Government seeks mature, currently operational facilities, personnel, processes, tooling, and infrastructure—not conceptual or developmental solutions requiring significant new construction or multi-year stand-up. Interested sources may support all or part of the workload, including aircraft induction, preservation, inspection/documentation, SLM specification modifications, structural technical directive incorporation, Block III upgrade kit installation, material procurement/management, inspection-based repairs, parts manufacturing/sourcing, systems troubleshooting, records updates, and functional check flight support. Respondents should demonstrate relevant tactical aircraft MRO/modification experience, facility and throughput capacity, technical capability, staffing, cybersecurity compliance, and any Government enablers needed; the anticipated maximum SLM induction profile is up to 47 aircraft per year across the industrial base. Information will inform the Government’s long-term acquisition strategy through 2038, including whether to add a qualified source or maintain the current hybrid framework.
