N6833525RFI0435: horizon reference system for arleigh burke-class guided missile destroyers, constellation-class frigates, and freedom and independence-class littoral combat ships

The Department of the Navy Naval Air Systems Command Naval Air Warfare Center is seeking to procure a Horizon Reference System (HRS) for multiple naval vessel classes including Arleigh Burke-class guided missile destroyers, Constellation-class frigates, and Freedom and Independence-class littoral combat ships. This pre-solicitation notice represents Amendment 0005 and includes responses to industry day questions regarding technical specifications for the navigation and guidance system. The government intends to compete this requirement and will release a draft Request for Proposal (RFP) with sections L & M that will provide comprehensive technical requirements currently missing from the initial documentation. Key technical areas requiring further definition include gyroscope interface details, cybersecurity considerations, packet formatting rules, power verification methods, and component coating requirements. The response deadline for this pre-solicitation is September 24, 2025, with industry stakeholders advised to review the existing RFI System Specification while awaiting the forthcoming draft RFP.

This opportunity does not utilize any set-aside designations and will be open to full and open competition. The government file indicates that multiple vendors have submitted technical questions during the industry engagement phase, suggesting active interest from the defense contractor community, though no specific incumbent contractors or potential bidders are identified in the available documentation. The notice does not disclose estimated contract values, award amounts, or budget ranges for this procurement. Similarly, specific quantities of horizon reference systems to be procured or delivery timelines are not detailed in this pre-solicitation phase, with such information expected to be included in the upcoming draft RFP that will contain the complete technical specifications and contract requirements.
