Silent Service of World War II
Here was the Silent Service Boats Of World War II. When the Japanese attacked Pearl Harbor on 7 December 1941, the U.S. Navy had a total of 111 submarines. However, this fleet was not nearly as impressive as the number suggests. It was mostly a collection of aging boats from the late teens and early twenties, with only a few of the newer, more modern Gato-class boats. Fortunately, with the war in Europe was already two years old and friction with Japan ever-increasing, help from what would become known as the Silent Service in the Pacific was on the way: there were 73 of the new fleet submarines under construction.
