After emerging from the 5-year refit in May 2023, Iron Duke spent the best part of a year on sea trials, workup and FOST certification.

Royal Navy Type 23 frigate HMS Iron Duke has been stripped of her weapons and sensors and has not been to sea since October 2025, despite no formal decommissioning announcement being made, reports Navy Outlook. As RN Atlantic Patrol Tasking, South, she was well known in the Falkland Islands which she visited on several patrol duties.

Her withdrawal from active service, less than three years after a £103M refit, raises uncomfortable questions about the Royal Navy’s ability to sustain even its much-reduced surface fleet.
