WASHINGTON, D.C. — U.S. Sen. Maine Angus King is bundling up for a military excursion to the Arctic.

King will be aboard with the Navy this weekend as it tests combat systems in the frigid Arctic Ocean. The senator says the trip will help him make better decisions in Congress through his position on the Armed Services Committee.

King says he will tour the Navy’s ice camp built by the Arctic Submarine Laboratory. He will also board a submarine and observe training exercises.

The U.S. says the Arctic is a region important to national security. The Navy trains in the challenging environment every three years to test combat readiness.
