diagram showing how anti-torpedo torpedo system works

A torpedo designed by engineers at Penn State's Applied Research Laboratory can track and destroy enemy torpedoes. When an acoustic sensor array towed behind a ship detects an approaching torpedo, a human operator on the ship fires the countermeasure anti-torpedo torpedo (CAT), which finds and "kills" the incoming torpedo. Distance is compressed in this diagram.
