The NATO SEASPARROW Project Office (NSPO) issued Special Notice N0001425SN0004-0001 to announce the postponement of the Evolved SEASPARROW Missile New Variant Development Industry Day. Originally scheduled for October 14, 2025, the event was delayed due to a government shutdown. Future updates regarding the Industry Day will be disseminated through amendments to this special notice. Interested parties with questions are advised to contact the points of contact listed in the original announcement. This amendment serves to inform potential participants of the schedule change and directs them to existing resources for further information.

The NATO SEASPARROW Project Office (NSPO) / PEO IWS 12.0 is hosting an Industry Day on January 28-29, 2026, in Washington, D.C., to discuss the development of a Next Significant Variant (NSV) missile system, a successor to the ESSM Block 2. This two-day event, rescheduled from October 2025, aims to engage existing and potential industry partners in designing and developing a new missile variant that can address current and future threats while maintaining existing quad-pack sizing and a 10-inch missile diameter. The NSPO, a twelve-nation international consortium, emphasizes digital engineering and model-based systems engineering for efficient communication of missile designs and requirements. The Industry Day will feature classified morning sessions detailing consortium requirements and operational techniques, and unclassified afternoon sessions covering the consortium overview, current products, future direction, acquisition approach, and methods for assessing technological candidates. Registration is required by January 21, 2026, and attendees must possess at least a SECRET clearance, be citizens of and represent a company headquartered in one of the twelve NATO SEASPARROW Consortium partner nations. This notice is not a request for proposals, and participation is not required for future opportunities.

The NATO SEASPARROW Project Office (NSPO), in collaboration with NavalX and the Office of Naval Research (ONR), is hosting an Industry Day on October 14, 2025, in Washington, DC. The event aims to engage industry partners in developing a Next Significant Variant (NSV) missile system to succeed the ESSM Block 2. This new variant must handle current and future threats, maintain existing quad-pack sizing, and utilize open-architecture standards for consortium partners. NSPO emphasizes digital engineering and model-based systems engineering for efficient design and requirement communication. White papers are expected to cover all aspects of the NSV missile, including seeker technologies, autopilot, and warhead design. The Industry Day will feature an overview of the consortium, current products, future direction, and a classified briefing on requirements. The afternoon session will focus on the acquisition approach and leveraging digital engineering. This classified event requires attendees to possess a Secret clearance, hold citizenship, and represent a company headquartered in one of the twelve NATO SEASPARROW consortium partner nations. Registration closes on October 7, 2025, or when capacity is reached. This notice is for informational purposes and does not constitute a request for proposals.
