The U.S. Navy has awarded Ultra Maritime a development contract for the MK6 Acoustic Device Countermeasure to address the rapid evolution of adversary torpedo technology.

Modern undersea warfare is being redefined by smarter, stealthier, and more lethal torpedoes capable of outmaneuvering traditional decoys and re-acquiring targets with high precision. To counter these threats, the ADC MK6 is designed for rapid deployment and speed, generating powerful, tailored acoustic signatures specifically engineered to confuse and divert incoming undersea weapons. This system provides a trusted layer of defense intended for use in highly contested maritime domains and high-threat environments.

The design for the next-generation program is built upon a decades-long record of delivering countermeasure systems to navies worldwide. This specific development was jumpstarted by years of independent investment by Ultra Maritime, highlighting a commitment to providing allied fleets with future-ready undersea protection. The new system emphasizes mission-ready performance, improved acoustic output, and robust compatibility.

Ultra Maritime continues to operate across the anti-submarine warfare sector, producing a range of technologies from sonobuoys and sonar systems to acoustic countermeasures. This latest contract focuses on maintaining a technological edge against both current undersea threats and future unknown developments in torpedo technology.
