USCGC Sea Fox

USCGC Sea Fox was the last Marine Protector-class patrol boat coastal patrol boat to be built. Her first home port was Bangor, Washington where she was part of the Coast Guard Maritime Force Protection Unit there, in company with her sister ship USCGC Sea Devil (WPB-87368).

Unlike most cutters in her class she is owned by the United States Navy, although she is staffed by United States Coast Guard personnel. She and three of her sister ships (Sea Devil, Sea Dragon and Sea Dog) were employed to protect the Navy's largest submarines, the nuclear-armed Ohio-class submarine, while the submarines were in or near their moorings. These four cutters mounted an additional gyro-stabilized remotely controlled machine gun.

When Sea Dragon and Sea Dog, assigned to Coast Guard Maritime Force Protection Unit Kings Bay, were decommissioned on May 29, 2024, Sea Fox and Sea Devil replaced them.
