Ultra Maritime Tests Integrated ASW and Counter-UUV Sonar System During US Navy Exercise

Published Aug 14, 11:29 AM UTC

Ultra Maritime successfully demonstrated an integrated active-passive sonar system during the U.S. Navy's Lanternfish 2026 exercise. The system combines the company's Sea Spear deployable passive sonar array with the newly developed SSQ-125B active sonobuoy to detect and track unmanned underwater vehicles (UUVs). This demonstration validates Ultra Maritime's acoustic architecture for future autonomous counter-UUV and anti-submarine warfare (ASW) operations. The scalable solution supports the company's Ocean of Things vision—a distributed network of autonomous underwater sensors deployable from manned and unmanned platforms for persistent surveillance. Applications include port protection, critical infrastructure security, maritime choke point monitoring, expeditionary operations, and long-duration surveillance of strategic waterways. The SSQ-125B is described as the only active sonobuoy of its kind, designed exclusively by Ultra Maritime, and together with Sea Spear creates an integrated detection ecosystem that extends range, persistence, and effectiveness of autonomous ASW operations.
