Situated some 200 miles inside the Arctic Circle at the Joint Helicopter Command (JHC) training facility near Bardufoss, Northern Norway, the JHC base known as 'Clockwork' provides survival and operational training and support facilities to enable aviation capable units arms to survive, operate and fight in extreme cold weather environments.

It enables CHF to prepare for future operations and is fundamental to the delivery of littoral manoeuvre for the Royal Navy given the geography and excellent facilities that exist in the local area. 150 Naval personnel from Commando Helicopter Force normally based at the Royal Naval Air Station Yeovilton in Somerset will take part in their annual winter training exercise in Northern Norway.
