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.
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.
U-boats, packs of German U-boats searching for American ships were called wolf packs
It was called the Lusitania
In the EPL...3 Subs Universally in the main its also 3 subs
The Germans sunk more, cause the US didn't have many, and most of them were in the Pacific.
German subs were looking for targets; just like the Japanese subs were off the US west coast...looking for targets.
German subs are known as Unterseeboote, U-Bootefor short.
Most subs that were lost we're on Germany's side because they employes the most subs, and after the code was broken subs began sinking on the German side routinely.
German subs fought "Guerre de Course." (Merchant Sinkings) Japanese subs fought "Guerre de Escadre." (Warships vs Warships) US subs fought both.
U- Boats
German subs sinking the Lusitania and the Zimmermann Telegram.
We entered World War 1 because of a German submarine attack on U.S. merchant ships in 1917.
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.
PUSH
Yes. Midget subs.
11 starting men, and around 10 subs
Same as subs from other nations, only the markings (words/numbers) were in German.
