The Germans sunk more, cause the US didn't have many, and most of them were in the Pacific.
They were there to sink as many ships as possible. Some were given the role of landing spies but that was always subordinate to the role of sinking ships.
U-boats, packs of German U-boats searching for American ships were called wolf packs
The German U boats helped in world war 1 because the U boats could sail around the sea and water. The German U-boats helped a lot They could sail around the water that is good They could go underwater, so they were able to sink many ships without being detected until the utilization of airplanes as escorts by the Allies
Same as subs from other nations. The first German U-Boats, such as U1 (launched in 1906) which originated from a batch of subs sold to Russia during the Russo-Japanese War in 1904 had one torpedo tube. By WWII some subs had 6 tubes, plus a deck gun.
Mini-Subs launched from mother ships; dive bombers, torpedo bombers, and fighters.

To sink enemy vessels, ships or submarines.

IJN & USN subs went looking for ships to sink.
Two or more subs made up a wolf pack.
We entered World War 1 because of a German submarine attack on U.S. merchant ships in 1917.
For the very same reason US subs were a danger to Japan during WWII. Japan & Britain are both Islands. Islanders depend upon IMPORTS. Subs sink ships. Ships IMPORT!
Operation Deadlight was the scuttling in deep waters of most of the German subs. So a LOT of German subs were used there to be sunk. The Navy did retain a number and used most of them for target practice later on. Some lived on to be museum ships. But the sheer number of the German subs captured meant scuttling was the only option: the Allies were already waist-deep in surplus ships and subs themselves and many of those were scuttled or scrapped as well.
subs have empty tanks in them. this empty tanks are filled with water when the subs need to sink and emptied when the subs need to float.

German subs are known as Unterseeboote, U-Bootefor short.
Main weapons of German subs were torpedoes and a cannon on the foredeck. If the target was entirely unarmed and the conditions good the sub would have surfaced and then used the gun. Poorer conditions, or an armed target forcing the sub to remain hidden would have caused the torpedoes to be used instead.
