The UK’s Royal Navy has withdrawn its fleet flagship from a historic NATO exercise on Norway’s Arctic coast over what it says are issues with the vessel’s propeller.

According to Marine Industry News, the HMS Queen Elizabeth had been due to sail from Portsmouth on Sunday evening (4 February) until routine checks identified an issue with a coupling on the vessel’s starboard propeller shaft.

The £3.5bn, 65,000-ton aircraft carrier — which has parts constructed in the same shipyard that built the Naval Service’s LÉ George Bernard Shaw — will be replaced by sister ship HMS Prince of Wales in exercise Steadfast Defender 2024.

The Prince of Wales has had its own share of propeller issues, previously breaking down shortly after setting out for the United States on deployment in August 2022.

Steadfast Defender 2024 is NATO’s largest exercise since the end of the Cold War, involving some 90,000 military personnel from all NATO members and Sweden.
