HMS Argyll (F231) was a **Type 23 Duke-class** anti-submarine warfare frigate of the Royal Navy, laid down in 1987 by Yarrow Shipbuilders in Glasgow, launched in 1989, and commissioned in 1991 as the longest-serving vessel in her class. Designed for versatility, she was equipped with the Sea Ceptor air defence missile system (the first Type 23 to receive it), a 4.5-inch gun, anti-ship missiles, torpedoes, and facilities for a helicopter, enabling roles in anti-submarine operations, maritime security, drug interdiction, and humanitarian missions. Argyll participated in key deployments, including the Sierra Leone intervention in 2000, multiple Gulf patrols, and Pacific operations. She was decommissioned in 2024 after 33 years of service, sold to BAE Systems for use in apprentice training and shipbuilding support, with her ship's bell presented to the Duke of Argyll in 2025 as a symbolic end to her career. As of early 2026, she is no longer in naval service.
