The Old School Way to Sink a U.S. Navy Aircraft Carrier

Of course, just like the carrier-based ATTDS, the CRAW anti-torpedo torpedo would also require testing to see if they work as well in practice as they do in theory. Nonetheless, the concept of adding an additional close-range layer of protection to submarines has merit given the increasing capability of modern torpedoes, and the sobering reality that a submarine would be lucky to survive even a single torpedo hit.In 2019, an annual report released by the Department of Testing & Evaluation revealed that a potentially revolutionary new torpedo-defense system installed on five American aircraft carriers had proven unsatisfactory and would be withdrawn from service.(This first appeared last month.)The system combined a towed Torpedo Warning System sensor array designed to detect incoming torpedoes with a quick-acting launcher called the Anti-Torpedo Device System (ATTDS) that could spit out a miniature 220-pound Countermeasure Anti-Torpedo (CAT) measuring only 171 millimeters in diameter. The CAT torpedo was designed to home in on the incoming torpedo and blast it short of its target.
