The Navy plans a “sinkex” (sink exercise) next week using as a target the former USS Durham, a 575-foot amphibious cargo ship that saw service in the Vietnam War and participated in the evacuation of Saigon in 1975.

Canada said its frigates Regina and Winnipeg will fire missiles in the sinkex, with Winnipeg to fire Evolved Sea Sparrow missiles and torpedoes, while Regina will fire a Harpoon missile.
