WASHINGTON – U.S. Navy asked Leidos Inc. in Reston, Va., to develop an advanced active acoustic countermeasure to help U.S. defense services and its allied submarine forces against modern acoustic-homing torpedoes. Officials of the Naval undersea Systems Command in Washington offered a $13.9 million contract to Leidos to test, design and build an Acoustic Device Countermeasure (ADC), that is also called the ADC MK5.
This defense countermeasure for the torpedo will generate noise to deceive the sonar guidance systems of incoming torpedoes that are coming towards for the sounds the target submarines are making. The contract to Leidos includes software and hardware developments for the defense technology to develop ADC MK5 torpedo defense mechanism with technical and non-recurring services.
ADC MK5 is a 3-inch-diameter that have acoustic communications links to connect and separate countermeasures devices to enable group behavior where the incoming torpedoes can be defeated. This technique can be employed in-groups of six units’ expendable device where the targeted submarines launch through external launchers that have advanced features where submarines can employ as static or mobile devices with adaptive countermeasure (ACM) technology.
The ADC MK5 mechanism can be re-programmable so that it can be operated together with U.S. and allied torpedoes or anti-torpedo systems to change tactics in response to environmental conditions via the acoustic communication link.
These countermeasures are developed with embedded processors and a built-in threat torpedo classifier where countermeasure operations and tactics can be employed any time based on acoustic to work against incoming torpedoes cooperatively.
