USCGC Storis (WAGB-21) is a United States Coast Guard medium icebreaker. She was originally built as the icebreaking anchor handling tug supply vessel (AHTS) Aiviq to support oil exploration and drilling in the Chukchi Sea off Alaska. The USCG acquired the vessel in December 2024 and she is expected to be commissioned to Coast Guard service in August 2025.
