USS Nimitz now armed with anti-torpedo defense system

USS Nimitz became the latest nuclear-powered aircraft carrier to have a hard-kill anti-torpedo defense system when the carrier left the shipyard last week.

The Surface Ship Torpedo Defense (SSTD) System consists of the Torpedo Warning System, an automated control station and a Countermeasure Anti-Torpedo (CAT).

Developed by Pennsylvania State University’s Applied Research Lab, the Countermeasure Anti-Torpedo is designed to destroy an incoming torpedo by collision.

USS Nimitz is the fifth aircraft carrier to be equipped with this technology.
