The Navy is opening a marketplace for the Medium Unmanned Surface Vessel (MUSV) family of systems program, focusing on high-capacity logistics support and containerized payload transport. A Request for Prototype Proposal will be released by 01 August 2026, using Other Transaction Authority to accelerate design and demonstration. The effort seeks expertise in vessel construction, autonomy, and maritime problem solving, with awards intended for prototype projects demonstrating operational capability. Performance location is not specified, and no budget amount is provided. This opportunity is for parties interested in developing adaptable, resilient unmanned surface vessel solutions.
