Officials of the Naval Undersea Warfare Center Division Keyport in Keyport, Washington, announced a $42.1 million contract with Ultra Electronics to build its Acoustic Device Countermeasure (ADC) MK 2 torpedo decoy for surface warships.
The ADC MK 2 is a battery-powered expendable sonar countermeasure for use by surface ships and submarines to counter torpedo threats. When deployed, it hovers vertically at a pre-selected depth using a pressure-controlled motor driving a small shrouded propeller in the tail of the decoy, and emits an acoustic signal to spoof incoming torpedoes.
The system essentially uses sound to divert or confuse homing torpedoes to help naval forces create a multilayer defensive screen. The ADC MK 2 is part of an integrated sense-to-effect solution that helps surface ships survive torpedo attacks.
The system employs advanced acoustic processing techniques to detect and classify torpedo threats with a very low false alert rate and high probability of correct classification.
The technology is expected to be finished by July 2027.
