Evolved SEASPARROW Missile (ESSM) Releasable Seeker Assembly Sources Sought

The NATO SEASPARROW Project Office (NSPO) is conducting market research through a Request for Information (RFI) to gather concepts for a releasable seeker assembly for the Next Significant Variant (NSV) of the Evolved SEASPARROW Missile (ESSM). This seeker subsystem must be open, modular, standards-driven, and capable of long-term affordability, rapid capability insertion, and international cooperation among the 12 consortium nations. The RFI seeks concept descriptions addressing operational needs against current and future threats, integration into a 10-inch missile body, and adherence to an open-source architecture with maximum government rights to technical data. Responses, due by April 27, 2026, must detail company capabilities, experience, export control compliance, production plans, cost estimates, development timelines, security clearances, and extensive technical characteristics of the proposed seeker. This RFI is for informational purposes only and does not constitute a request for proposal.

The NATO SEASPARROW Project Office (NSPO) is conducting market research through a Request for Information (RFI) to gather concepts for a releasable seeker assembly for the Next Significant Variant (NSV) of the Evolved SEASPARROW Missile (ESSM). The NSPO, a twelve-nation consortium, seeks an open, modular, and standards-driven architecture for the seeker to ensure long-term affordability, rapid capability insertion, and international cooperation. The seeker must integrate with a 10-inch diameter missile body, provide capabilities against various threats in complex environments, and handle countermeasures. Responses should detail technical characteristics, proposed architecture, data rights, cost estimates, development timelines, security clearances, and export control compliance for all 12 consortium nations. This RFI is for planning only and is not a request for proposals.
