(**RESCHEDULED**) NATO SEASPARROW Project Office (NSPO) Evolved SEASPARROW Missile New Variant Development – Industry Day N0001425SN0004

The NATO SEASPARROW Project Office (NSPO) / PEO IWS 12.0 and NavalX, the innovation organization for the U.S. Navy and Marine Corp and the Office of Naval Research (ONR), invite existing and potential industry partners to learn about the NATO SEASPARROW Consortium s effort to design and develop a new missile variant to follow the ESSM Block 2 in Washington, DC on Tuesday, October 14th 2025. The NSPO is a twelve-nation international consortium with a mission to provide a platform for international cooperation and innovation to manage the development, production, integration, and sustainment of effective, reliable, and affordable weapon systems to protect consortium and partner nation forces from current and future threats. More information on the NATO SEASPARROW Surface Missile System Project can be found at this link; https://www.natoseasparrow.org The NSPO welcomes existing and new industry partners, without prejudice to companies with limited government contracting experience. Potential partners with strong technical competence in their particular field may be successful with a high willingness to learn and adapt digital engineering processes and respond constructively to the NATO SEASPARROW Consortium s needs. The Industry Day will consist of a morning session (0830 1130 EDT) and afternoon session (1300 1600 EDT). The morning session will begin with an overview of the NATO SEASPARROW Consortium and Project Office, current consortium products, and the future direction in comparison to current systems. The morning session will end with a CLASSIFIED briefing of the consortium s requirements for a future missile system with the operational techniques and technical capabilities that may be needed to meet them. The afternoon session will focus on our acquisition approach, including timelines, a discussion of how we aim to leverage digital engineering, and methods for assessing technological candidates and industry partners. Registration This CLASSIFIED event may include information classified up to the SECRET level. ATTENDEES MUST MEET ALL OF THE FOLLOWING REQUIREMENTS: POSSESS AT LEAST A SECRET CLEARANCE HOLD CITIZENSHIP OF ONE OF THE TWELVE NATO SEASPARROW CONSORTIUM PARTNER NATIONS REPRESENT A COMPANY HEADQUARTERED IN ONE OF THE TWELVE NATO SEASPARROW CONSORTIUM PARTNER NATIONS. Attendance will be limited to two people per company (one primary attendee and a plus-one). If capacity is reached, plus-ones will be asked not to attend to allow additional companies to be represented. Registration will close on October 7, 2025, at 1200 EDT, or when we reach max capacity, whichever comes first. To register for the event, use the following link (may require accessing from a personal computer): https://forms.osi.apps.mil/r/hgeBFtTj8F

Amendment 0002 **RESCHEDULING ANNOUNCEMENT** The NSPO Evolved SEASPARROW Missile New Variant Development Industry Day has been rescheduled from 14 October 2025 to 28-29 January 2026. Please reference the attached Amendment 0002 document for full registration details. Amendment 0001 **POSTPONEMENT ANNOUNCEMENT** Due to the Government shutdown, the Evolved SEASPARROW Missile New Variant Development Industry Day previously scheduled for 14 October 2025 is postponed until further notice. Future information regarding the Industry Day will be provided via amendments to this special notice. If you have questions, please contact the points of contact listed in the original announcement. The NATO SEASPARROW Project Office (NSPO) / PEO IWS 12.0 invites existing and potential industry partners to learn about the NATO SEASPARROW Consortium s effort to design and develop a new missile variant to follow the ESSM Block 2 in Washington, DC on Wednesday and Thursday, 28-29 January, 2026. This event has been rescheduled from a single day event on 14 October 2025, which was postponed due to U.S. Government shutdown, to a two-day event to allow more participation. The government will present the same information on both days and industry is asked to sign up for only one of the two days. NSPO is a twelve-nation international consortium with a mission to provide a platform for international cooperation and innovation to manage the development, production, integration, and sustainment of effective, reliable, and affordable weapon systems to protect consortium and partner nation forces from current and future threats. More information on the NATO SEASPARROW Surface Missile System Project can be found at this link; https://www.natoseasparrow.org. The NSPO is exploring technology to be incorporated into a Next Significant Variant (NSV) missile system. This successor to the ESSM Block 2 must be able to engage current and future threats while maintaining existing quad-pack sizing with a 10 missile diameter. Drivers for development include stressing simultaneous engagement scenarios, the need to develop fully releasable technologies using open architecture standards for all consortium partners to openly share, and the need to maintain capability with current consortium systems to the greatest extent possible while limiting ship support. To develop the NSV missile system, the NSPO will lean heavily on digital engineering and model-based systems engineering to communicate missile designs and requirements efficiently among consortium nations and industry partners in a shared development environment. These tools will be used to evaluate weapon systems and missile technologies through a design alternative evaluation process. White papers are expected to include all aspects of the NSV missile including seeker technologies, autopilot, computing stack, internal communications, rocket motor alternatives, warhead design, missile to missile communications, data links, combat system integration, etc. NSPO previously submitted a sources sought for an Open Source M&S Suite (see Notice N00024-25-R-5430) able to interface with a missile system model written in the SysML v2 systems modeling language. The missile system model will include subsystem/component models of technology solicited from industry partners. The NSPO welcomes existing and new industry partners, without prejudice to companies with limited government contracting experience. Potential partners with strong technical competence in their particular field may be successful with a high willingness to learn and adapt digital engineering processes and respond constructively to the NATO SEASPARROW Consortium s needs. Each day of the event will consist of a CLASSIFIED morning session (0830 1130 EDT) and afternoon UNCLASSIFIED session (1300 1600 EDT). The morning CLASSIFIED session will be a briefing of the consortium s requirements for a future missile system with the operational techniques and technical capabilities that may be needed to meet them. The afternoon UNCLASSIFIED session will cover an overview of the NATO SEASPARROW Consortium and Project Office, current consortium products, and the future direction in comparison to current systems. The afternoon session will also focus on our acquisition approach, including timelines, a discussion of how we aim to leverage digital engineering, and methods for assessing technological candidates and industry partners.
