The US Navy (USN) will begin a three-month evaluation of Saab’s anti-submarine warfare (ASW) training system later this year.

The demonstration will take place at the Atlantic Undersea Test and Evaluation Center (AUTEC) in the Bahamas using the company’s AUV62-AT, an artificial acoustic system that mimics a submarine.A Saab AUV62-AT during an exercise.

AUV62-AT, which is both active and passive target, was designed around the Swedish Navy’s Mk 62 torpedo. The platform can be programmed to emit signals similar to existing submarines, for example, it can transmit signals to appear as a Russian Akula-class submarine, Chris Lade, defence sales manager for Saab, told Jane’s on 9 January at the annual Surface Navy Association conference in Arlington, Virginia.

“The AUV62-AT is also an active target so it is designed to process what it receives from sonar, and return that ping after it has processed it, as if it were the shape and form of a submarine,” Lade said.

A series of hydrophones in a towed array enable the AUV62-AT to do that, he added.

The platform also acts as an active target which is aspect dependent, so for example if it is ‘pinged’ from the front, a sonar operator on a ship or submarine would receive a front ‘ping’ back.

Additionally, operators can get post-exercise analysis from the AUV62-AT. The system records what the assets are doing as they are searching for the ASW trainer. Upon completion of the exercise the system will provide data that plots the location of each asset, whether air, sea, or undersea during the exercise.

A submarine could also fire a dummy torpedo at the AUV62-AT, which will record the torpedo’s attack and provide the ability to assess how well the training went during the firing.
