ARLINGTON, Va. — When the nuclear-powered aircraft carrier USS Nimitz emerged from an extended period in a shipyard last week, it featured a new installation of an anti-torpedo system.
Nimitz is the Navy’s fifth carrier to have the Anti-Torpedo-Defense System installed. The system includes the Torpedo Warning System, an acoustic sensor that detects an incoming torpedo; a tactical control station; and the Countermeasure Anti-Torpedo (CAT). The CAT, a small torpedo designed to intercept an incoming torpedo, was developed by Pennsylvania State University’s Applied Research Lab.
Compared with air- or ship-launched cruise missiles, anti-ship torpedoes are much more difficult for a ship to defend against because the medium of water is more opaque and distorted to sensors.
The anti-torpedo defense system was one of several improvements added to the ship, including two Mk38 25mm guns and the Consolidated Afloat Network Enterprise Services system, according to an Oct. 5 Navy release announcing the Nimitz’s commencement of sea trials following a 20-month Extended Planned Incremental Availability at Puget Sound Naval Shipyard, Bremerton, Wash.
An engineering and development model (EDM) of the anti-torpedo system was tested in May 2013 from USS George H.W. Bush and deployed in 2014. A roll-on/roll-off model was deployed on USS Theodore Roosevelt and USS Dwight D. Eisenhower. A second EDM was installed on USS Harry S. Truman. The Navy plans to equip all aircraft carriers and other high-value ships with the system by 2035.
