Hms Iron Duke withdrawn, leaving Royal Navy with 5 frigates
hms iron duke has been withdrawn from active service after being stripped of her weapons and sensors and not going to sea since October 2025. The Type 23 frigate is now effectively out of front-line use, leaving the Royal Navy with just 5 frigates.
The ship’s early removal comes less than three years after a £103 million life extension refit completed in May 2023. That work took 49 months and more than 1.7 million man-hours, and the expectation on completion was that she would serve for at least 5 years.
Iron Duke in Portsmouth and Devonport
Iron Duke was laid up in Portsmouth in 2017 before arriving in Devonport in May 2019 to begin the refit. The overhaul removed her obsolete Harpoon system, and she was fitted for, but never received, the Naval Strike Missile system.
After the refit ended, the frigate spent the best part of a year on sea trials, workup and FOST certification. She then moved through a short period of front-line activity that included monitoring Russian vessels passing through the English Channel.
King, Prime Minister and Baltic duty
The ship attended DSEI 2023 in September 2023 and hosted the King. She later hosted the Prime Minister in Tallinn after the Joint Expeditionary Force summit in December 2024, visited Norway in March 2025 and spent a few weeks in the Baltic on her only major overseas deployment.
Her commanding officer said the ship had been activated to monitor Russian vessels in or close to UK waters 13 times in the preceding 12 months. In January 2026, Iron Duke still retained most of her ship’s company, even though rumours pointed to personnel shortages and a possible transfer of most of the crew to HMS Kent.
MoD and March 2026 plans
The Ministry of Defence said in November 2025 that plans to fit Iron Duke with the towed array sonar had been abandoned because the benefits of proceeding did not justify the additional cost. The ship was supposed to go back to sea in March 2026, but instead she has been stripped and taken out of active service without a formal decommissioning announcement.
For the Royal Navy, the immediate result is a smaller frigate force and one less hull available for operations at a time when Iron Duke’s refit has ended in early withdrawal rather than another run of service. The crew issue now sits alongside the ship’s removal from active duty, with the practical consequence that one of the fleet’s long-refitted frigates has already stopped making sea time before the planned return date.
