UK’s Only Polar Icebreaker is Towed to Port to Investigate “Defect”
UK media is speculating that the Royal Navy may be facing a significant problem after its only polar icebreaker, HMS Protector, appears to have suffered a significant failure. Reports are indicating that the now 25-year-old survey and scientific vessel used as a demonstration of sovereignty in the polar regions has experienced a potentially serious mechanical failure without plans for a replacement.
The publication Naval Lookout and local newspapers are reporting that HMS Protector was towed into her homeport at Davenport on October 13. A Royal Navy spokesperson would only say that it was to permit “investigations into a defect” aboard the vessel. There is no official word on the scope of the problem, but the daily newspaper The Telegraph is reporting that the vessel experienced a “double-engine defect” while at sea, requiring a tow to return to port.
The latest incident comes after the vessel, which was originally built in Norway in 2001 as Polarbjorn, had just undergone her five-year drydocking in 2025. She was given a significant overhaul, which was designed to extend her operations.
The vessel, which has a DNV Ice Class 05 rating with a capability of maneuver through first-year ice up to 20 inches (0.5 meters), was built as a commercial polar research and subsea support vessel by GTC Rieber Shipping. The Royal Navy took her on an emergency charter in 2011 for three years, designed to fill a gap after the prior polar vessel, HMS Endurance, also experienced a catastrophic failure that resulted in flooding on the vessel.
The Royal Navy acquired HMS Protector in 2013 and completed her outfitting for its polar missions. Between 2015 and 2019, she was deployed full-time to the Southern Hemisphere at sea for as much as 330 days and based in South Africa. The ship has a displacement of 5,000 tons and has an overall length of 89 meters (292 feet). She has a normal complement of 88 and is also capable of embarking a Royal Marine detachment.

Her primary mission has officially been to carry out observations, fishery inspections, and hydrographic surveys. However, she was mostly seen as a demonstration of British sovereignty and spent the past few seasons splitting her time between the Arctic and Antarctic. Supply missions to the UK’s Antarctic station are carried out by the British Antarctic Survey, which commissioned its vessel RRS Sir David Attenborough in 2021 after construction delays.
HMS Protector suffered propulsion problems in 2019, which required a 10-month overhaul and meant she missed her 2020-2021 season. She returned to the Arctic in 2021 and later that year made her first visit to the Antarctic since 2019.
Commentators are noting that the failure comes at a challenging time as Argentina has become more active and is presenting new challenges to the British Falkland Islands. HMS Protector was used to show the flag and maintain a presence in the region in the past and would be missed this year.

The UK government had begun discussions about a potential replacement for the icebreaker, but no decisions had been reached as it struggles with the overall plans for the Royal Navy. Funding was being established, but the government said a decision on how to procure the new vessel had not been reached. Critics further assert that the UK needs two capable vessels to maintain its presence in each polar region.
Speculation is that the Royal Navy might again be in a challenging position as it found itself in after the failure of HMS Endurance in 2008. It might again have to seek out a stopgap solution similar to what led to the acquisition of HMS Protector.
