Northrop Grumman has successfully demonstrated the integration of its AN/AQS-24 anti-mine sonar system with an unmanned surface vessel for the US Navy, advancing efforts to shift mine countermeasure missions toward uncrewed platforms. Conducted in Panama City, Florida, the trials occurred just 45 days after contract award, underscoring rapid development and deployment timelines. During the demonstration, the towed sonar operated effectively from a drone vessel, meeting all primary objectives set by the Navy while improving safety and mission efficiency. The AN/AQS-24 combines a high-speed synthetic aperture sonar with an optical laser sensor to detect, classify, and localize surface and subsurface mines. Capable of operating at speeds up to 18 knots and previously tested at depths exceeding 400 feet, the system offers robust performance across diverse maritime environments. Currently deployed on MH-53E Sea Dragon helicopters and Littoral Combat Ships, the sonar’s migration to autonomous vessels supports Pentagon objectives to reduce sailor exposure to mine threats. When paired with USVs, the system can conduct standoff detection missions in shallow and deep waters alike, maintaining effectiveness while keeping personnel out of harm’s way.
