The Technology Application Program Office (TAPO) is conducting market research to identify vendors capable of providing non-recurring engineering support, trade studies, and production for modifications to the IVCS system on the H-47 Chinook, with a potential sole-source contract anticipated for Parker-Lord. The government seeks vendors with demonstrated experience in vibration control system trade studies, system design and production, legacy IVCS upgrades, program management, and sustainment services. Performance of services is not explicitly specified, but the work involves integration and flight testing for the H-47 Chinook. No budget amounts are mentioned in the description. Responses are due by 10:00 AM Eastern Time on 23 June 2026.
