US Navy tasks Ultra Maritime to develop next-gen acoustic countermeasure system

February 19, 2026, by Fatima Bahtić

Ultra Maritime has been awarded a development contract by the US Navy to design the next-generation acoustic device countermeasure (ADC) MK6, a system intended to enhance protection against evolving underwater threats.

The rapid evolution of adversary torpedo technology is redefining the undersea battlespace. With smarter, stealthier, and more lethal torpedoes that easily outmaneuver traditional decoys and that adapt and re-acquire targets with remarkable precision, the need for next-generation torpedo defense solutions has never been greater.

Ultra Maritime’s ADC MK6 is built for rapid deployment and speed, generating powerful, tailored acoustic signatures to confuse and divert incoming undersea weapons.

According to the company, the system is developed to deliver mission-ready performance and improved acoustic output.

From sonobuoys to sonar systems to acoustic countermeasures, Ultra Maritime continues to work on anti-submarine warfare innovation.

To remind, the company was recently awarded a contract from the UK Ministry of Defense (MoD) to deliver sonobuoys for the Royal Navy’s Merlin maritime patrol helicopter. Ultra Maritime is also working with the MoD on miniaturized sonobuoys for uncrewed air systems, expanding the UK’s future undersea surveillance reach and accelerating the transition to next-generation autonomous ASW systems.
