The Navy is conducting a sources sought notice for market research to identify vendors capable of performing complex P-8A Increment 3 Block 2 (ECP6) retrofit installations, involving de-installation of existing systems, installation of government-furnished kits, and return-to-service. Interested parties must submit a Capability Statement and a detailed questionnaire covering company profile, facilities, security infrastructure, past performance on Boeing 737/P-8A aircraft, quality certifications, and capacity/throughput rates. The questionnaire also requires information on Boeing licensing agreements, data rights, and the ability to perform at least 50% of work for small business set-asides. No budget or performance location is specified; the effort is expected to require hangar space for multiple P-8A aircraft and a turnaround time exceeding six to eight months per aircraft. The government will not reimburse submission costs and will only assess responses that allow review by government support contractors.
