The Royal Navy's HMS Kent has joined up with the US Navy in the Arctic for cold-weather training.
The Type 23 frigate joined two American destroyers, a nuclear submarine, support ship and long-range maritime patrol aircraft this week to practise operations in the challenging conditions.
The effectiveness of sonar, used by navies to detect other objects, navigate and communicate with other vessels, is impacted by the conditions in the Arctic.
More than 1,200 military personnel from the UK and the US are taking part in the exercise.
Commander Matt Sykes, the Commanding Officer of HMS Kent, said the challenges of working in the Arctic’s extreme conditions “should not be underestimated”.
Lieutenant Georgia Harding, HMS Kent’s Principal Warfare Officer, added the exercise is a “culmination” of high-intensity training that has seen “a step change” in HMS Kent’s readiness to conduct operations.
The Arctic exercise comes after the two nations conducted anti-submarine warfare training in UK waters a few weeks ago.
It is the second time in two months the Royal Navy has tested its capabilities off the Norwegian coast.
