The Naval Surface Warfare Center, Crane Division is seeking sources for JTT-R assemblies, components, and associated engineering, technical, and repair support services. This is a follow-on contract intended to be awarded on a sole-source basis to DRS Advanced ISR LLC in Beavercreek, OH, as any other source would cause significant cost and schedule delays impacting EA-18G mission support. The government is conducting market research to identify companies that can mitigate this sole-source justification by providing evidence of avoiding duplicative costs and time delays. Responses must be submitted by 26 May 2026 to be considered in the market research. Performance of services will be at NSWC, Crane Division in Crane, IN.
