In Britain, ASDIC.
In America SONAR.
Different names for the same thing!
United States Submarine Operations in World War II was created in 1949.
unrestricted submarine warfare
they copied there butts
it wass Germany i pretty sure but i cloud be wrong but take my word for it. __ When the war started in 1914, England had the largest submarine fleet in the world.
600 ft is threshhold
Asdic
Virginia class submarine
David Bushnell launched what is regarded as the world's first submarine.
England had the most powerful surface fleet of ships, while Germany had the most powerful submarine fleet. England's surface fleet won out over German submarines.
The world's first atomic powered submarine was the USS Nautilus.
The USS Nautilus (SSN-571) was the world's first operational nuclear submarine.
World War II submarines were powered by large electric motors. On the surface, the motors drew their power from diesel generators, not unlike how a diesel locomotive operates today. When submerged, the diesel engines could not be operated, and the motors drew their power from huge banks of electric batteries. After the batteries were drained of their power, the submarine would have to surface in order to run its diesel generators to provide propulsion and electric power to the submarine. During this period, the sub's batteries were recharged. Toward the end of World War II the submarine snorkel was invented, which gave a submarine the capability of running its diesel engines while submerged. The submarine was required to stay relatively close to the surface, but it was fully submerged with the exception of the snorkel mast. Nuclear powered submarines also have banks of electric batteries, but they are only used when the main propulsion plant and/or its steam-powered electric generators are disabled. When a nuclear-powered submarine's batteries are fully drained, they are recharged by the boat's diesel generator if its steam-powered electric generators are not available, or by the steam-powered electric generators when they becomes available. Just like a diesel-electric submarine, a nuclear-powered submarine must operate its diesel generator on or near the ocean's surface.
The submarine you are thinking about was the USS Nautilus. It was the world's first nuclear powered submarine and commissioned into the US Navy in 1955
A U-boat was a submarine used by Germany in World War 1 and World War 2.

There was no submarine that could do that as early as 1945
