Teribus, thats a very good and valid point..however..the term "Sub Hunter" is also used on our City Class Destroyers, Sea King Helicopter, and Aurora Aircraft. They do their job flawlessly with the exception of the Sea King. The Govt also says the Subs are needed for coastal defence, security, and for the Depts. of Oceans and Fisheries, as well as Customs and the RCMP. Also shared purpose as the Maritime Coastal Defence Vessel (MCDV) and again, the Sea King and Aurora....Slàinte!
