Calhoun (WMSL 759) is named to honor Charles L. Calhoun, the first master chief petty officer of the U.S. Coast Guard. Calhoun served in the U.S. Navy for three years during World War II and was honorably discharged in 1946 as a torpedo man second class. He enlisted in the Coast Guard that same year and held varying positions of leadership over the course of his career.
Ingalls Shipbuilding is the sole designer and provider of the Coast Guard Legend-class national security cutter. The flagship of the Coast Guard fleet, national security cutters are capable of embarking and supporting a wide range of Coast Guard, Navy and NATO manned and unmanned aircraft. National security cutters have proven to be ideal platforms for drug interdiction, global illegal fishing, disaster relief, and defense support operations.
Ingalls has delivered nine Legend-class national security cutters, and two more are under construction. Calhoun, the 10th national security cutter, is scheduled to be delivered early next year.
