Evolved SEASPARROW Missile (ESSM) Next Significant Variant (NSV) Sources Sought

The U.S. Navy, acting through the NATO SEASPARROW Project Office, is conducting market research to identify capable sources for the design, development, production, and in‑service support of a Next Significant Variant (NSV) of the Evolved SEASPARROW (ESSM) missile. The effort seeks a Guided Missile Assembly (GMA) or subsystem solution that fits a 10‑inch diameter, can be launched from Mk 41 VLS, and meets stringent performance, modularity, and open‑systems requirements for all 12 NATO consortium nations. Respondents are asked to submit a capabilities statement describing their technical, manufacturing, and programmatic ability to deliver the missile architecture, including airframe, propulsion, guidance, seeker, kill mechanism, datalink, software, and sustainment. The solicitation is purely informational; no funding is attached, and responses will be used for future acquisition planning, possibly leading to a prototype Other Transaction award. • Target product: ESSM Next Significant Variant (NSV) – guided missile assembly or subsystem set. • Required dimensions: ≤10 in diameter to fit Mk 41 VLS quad‑pack canister. • Performance envelope: wide speed, altitude, maneuverability, and signature ranges; robust against RF/EO/IR counter‑measures. • Architecture: Modular Open Systems Approach (MOSA) with maximum Government Purpose Rights in data/software. • Deliverables: design data, software source code, interface specifications, and support for international releasability. • Submission: Capabilities statement (≤15 pages PDF) by 17:00 ET, 3 Dec 2026; NDA/TOUA required for additional technical details (due 19 Oct 2026). • Evaluation focus: cost & schedule, TRL/MRL, MOSA compliance, export‑control compliance, and supply‑chain risk mitigation.
