Should the United Kingdom have ships able to operate in the Arctic?
Short answerYes, and cold-weather operation is already a longstanding Royal Navy design requirement.
NotesType 45 requirements weighted cold conditions more heavily than hot-weather operation because planners expected attention to move away from the Middle East. Norway, NATO's northern flank, and the Falklands all make low-temperature performance relevant to British ships. Experience later showed the cost of underweighting hot-weather demands. A globally used fleet needs both capabilities rather than optimizing around one climate.
