Ultra Maritime tests integrated ASW and counter-UUV sonar system during US Navy exercise

Published Aug 14, 11:29 AM UTC

During the U.S. Navy's Lanternfish 2026 exercise, Ultra Maritime successfully demonstrated an integrated active-passive sonar system combining its Sea Spear deployable passive array and the newly developed SSQ-125B active sonobuoy. The system was used to passively detect and actively localize unmanned underwater vehicles (UUVs), validating Ultra Maritime's acoustic architecture for future autonomous counter-UUV and anti-submarine warfare (ASW). The demonstration advances the company's Ocean of Things vision—a distributed network of autonomous underwater sensors deployable from manned and unmanned platforms. The scalable solution is intended for port protection, maritime choke point security, expeditionary operations, and long-duration surveillance. 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 for distributed undersea surveillance.
