Oh, nowadays there are civilised arrangements. The British spy on the American people and give the results to the American services, and in return the Americans spy on the British people and give the results to the British services.
Because if the double agents are all several-thousand-ton naval vessels than you need something with a little bit more punch than a Welrod to deal with them.
Also, is that Misaka Imouto's goggles? iirc there are no welding mask makers that make that style of block.

Ma'am.Set them free.Thank you for all your efforts.Thanks to the actions of our double agent, Akashi,we have found multiple Fairy-sans that we believe to be British Empire spies that have infiltrated the base.Nice to meet you, I'm Akashi!They're the same as ever, MI6...What.I would like information on the U-Boat that has apparently concealed herself in this base.If there's any dirty work you're wanting done in the base, then leave it to me!You would be the British Empire spy with all the dirt, yes?
