More Allied submarines operate from Singapore

Would the Royal Navy send more submarines to Singapore?

Yes; Singapore offers British, American, and Dutch boats a much more powerful position against Japanese sea lanes.

Britain would reinforce a viable Singapore submarine force. Compared with operating from Perth, Singapore places Allied boats much closer to the South China Sea, the Philippines, and Japanese invasion shipping. American and Dutch submarines could use the same forward geography, multiplying the coalition's patrol density. The base therefore magnifies the effect of every additional submarine assigned to the theater.
