Do the Brits have a navy?
Once upon a time...
Of course they have. There is just one tiny problem. Apparently, they can’t operate in hot weather. See this article: https://www.theguardian.com/uk-news/2016/jun/07/destroyers-will-break-down-if-sent-to-middle-east-admits-royal-navy
So the only Navy that mounts a Dalek on its ships is ineffective where it is warm.
