ARLINGTON, Va. – The Swedish defense firm Saab is set to demonstrate for the U.S. Navy an underwater drone that simulates a submarine, making it easier for ships and aircraft to practice anti-submarine warfare.

The company announced Tuesday that it was preparing to demonstrate its AUV62-AT drone for the Navy as part of the Foreign Comparative Testing program. The testing will start in the summer of 2018 and there is an option for more resting in 2019.

The drone, which is based on the company’s T-62 torpedo, mimics the acoustic signature of a submarine so that ships can get in their reps and sets on ASW, but spares the Navy the need to dispatch one of its busy submarines to aid with that training.

The company claims the AUV62-AT “fully replaces the use of a submarine in the role as a maneuvering training target,” and says it is already in use in several countries around the world.
