The United States currently fields both the largest Navy in the world, and currently the largest active submarine fleet. However, the US only operates Nuclear Submarines, the last Diesel-Electric boat being donated some years ago for research use. Many other nations operate DE submarines because of the lower cost, and because they don't have "blue water" navies - those which are global in nature. They only provide coastal defense.
