Protecting the Carrier Against Torpedo Attack
The prospect of torpedo attack against our high-value units periodically rears its ugly head and then submerges again as technology and tactics are developed to counter this threat, In our century's wars each major threat to the high-value unit was analyzed and dealt with after a few (or in some cases, a lot) of important ships were sunk in almost every case the most efficient and cost-effective mechanism used to attack these ships was a torpedo.
