Ultra Maritime Injecting Autonomous Undersea Capabilities into Next-Generation Torpedo Countermeasure Solutions for Future Anti-Submarine Warfare Dominance

BRAINTREE, Massachusetts – Ultra Maritime continues to advance its investment in the development of cutting-edge Next Generation Countermeasure systems — revolutionary autonomous undersea vehicles designed specifically as an anti-submarine warfare (ASW) solution.

These vehicles, both internally and externally launchable from submarines and unmanned undersea vehicles (UUVs), are engineered for independent operation. Once deployed, they maneuver away from the host platform to deliver real-time tactical updates and enhanced maritime domain awareness through robust acoustic communications.

As adversary undersea threats continue to evolve in capability, countermeasure systems must adapt to keep pace with both current and emerging challenges. To effectively counter these threats, traditional approaches alone are no longer sufficient — countermeasures must advance in sophistication, autonomy and adaptability. There is now a powerful convergence of technologies: torpedo countermeasures and UUVs, themselves. This convergence represents the next phase of ASW, where countermeasure systems integrate autonomous mobility, intelligent sensing and defensive effectors to provide a resilient, layered defense against evolving torpedo threats.

Recently, Ultra Maritime proved its capability in developing a full-duplex acoustic communication node, enabling secure, two-way information exchange between manned and unmanned platforms across the maritime battlespace. This capability enhances coordination and dramatically improves platform survivability in contested and high-threat environments.

Ultra Maritime has delivered more than 30,000 expendable torpedo countermeasures across a diverse portfolio of designs, reinforcing its position as the global leader in torpedo defense solutions.
