The Navy is announcing a forthcoming opportunity for Medium Unmanned Surface Vehicles (MUSV) Phase II Integration and Testing, emphasizing modular, adaptable designs for evolving threats. Vendors will be evaluated on platform maturity, open-architecture autonomy compatibility, endurance, payload integration capacity, and rapid-production scalability. The government intends to use streamlined acquisition authorities, including Commercial Solutions and Other Transactions, to award Basic Ordering Agreements, prototype agreements, and potentially production contracts. The formal Area of Interest release is planned on or before September 30, 2026, with a rolling open window to allow ongoing competition and updates from vendors. Approved platforms will be listed on the drones.mil maritime marketplace for authorized stakeholders to issue funded delivery orders.
