U.S. Coast Guard Cutter Kimball (WMSL 756) conducts a passing exercise with the Royal Canadian Navy ship HMCS Regina while Kimball patrols the Bering Sea, July 18, 2024. During Kimball’s 122-day patrol, the crew also interacted with strategic partners in Victoria, Canada, strengthening relationships by focusing on shared interests in the Bering Sea and the expanding Artic region.

The Indo-Pacific Defense Forum has a report on an exercise that indicates some degree of cooperation between the Coast Guard and the Air Force.
A key drill involved two B-52s simulating a long-range maritime strike. In a display of joint force precision, the bombers received targeting data from the U.S. Coast Guard cutter Kimball and U.S. Navy assets, allowing their crews to acquire targets from a significant distance and simulate a weapons engagement.
