This is a Request for Information (RFI) for market research to assist in planning the future acquisition of a Multifunction Tactical Radar System (MTRS) to perform air traffic control, battle management, unmanned aircraft surveillance, and weather sensing missions. The performance location is Hanscom Air Force Base, Massachusetts. The government requests that information be provided within five working days of receipt to arrange discussions, and seeks solutions that are actionable within the next year (FY2027) with the ability to deliver initial pre-production units within 29 months after a future award. The response must address detailed performance, transport, and technical requirements, and include a rough order of magnitude cost estimate.
