The crew of Coast Guard Cutter Stone (WMSL 758) returned to their homeport in North Charleston, S.C., on Wednesday after 63 days at sea seeking out drug traffickers in the Atlantic and Caribbean.

Stone served as on-scene commander in support of the Tri-Party partnership, leading U.S. Navy and Royal Canadian navy assets. The partnership, made up of U.S. Coast Guard Atlantic Area, U.S. Second Fleet and Canadian Joint Task Force-Atlantic maritime forces, was established in 2015 in support of homeland defense and counterdrug operations.

“This deployment offered a unique opportunity to demonstrate the diverse capabilities of the national security cutter and how seamlessly and rapidly the Coast Guard can integrate with joint and allied forces to counter maritime threats,” Capt. Jonathan Carter, Stone’s commanding officer, said in a service news release. “The Stone’s crew performed admirably throughout the demanding mission.”

Stone is a 418-foot, Legend-class national security cutter. Its primary missions are counterdrug operations and defense readiness. Stone falls under the command of the Coast Guard Atlantic Area in Portsmouth, Va.
