We entered World War 1 because of a German submarine attack on U.S. merchant ships in 1917.
Human hair was used by the German military to make slippers for the men on their subs. The hair came from the death camps.
USN had 3 carriers and 50 support vessels; IJN had 4 carriers, 7 battlehips and 150 support vessels.
Yes. Midget subs.
German subs had to surface for air. They couldn't avoid being seen by aircraft launched by CVE's; Escort Carriers, also known as "Jeep Carriers", "Baby Flattops." It was akin to rabbits being attacked by hawks and eagles everytime the rabbit came out of it's hole.
Yes. Some lighthouses had additional personnel assigned to them to stand look-out watches for enemy ships, subs, and planes. In specific circumstances the lights would be extinguised if known enemy contacts were in the area.

IJN & USN subs went looking for ships to sink.
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.
German subs fought "Guerre de Course." (Merchant Sinkings) Japanese subs fought "Guerre de Escadre." (Warships vs Warships) US subs fought both.
U-boats, packs of German U-boats searching for American ships were called wolf packs
Because the soon to be sunk merchant ship was radioing the subs position to the allies the whole time the sub was standing by awaiting for the ship to get it's passengers safely off. The sub was spending TOO MUCH TIME on the surface exposed to enemy hunter killer teams. German subs were being sunk and experienced skippers (captains) and their men were being killed because they were "being kind" (also known as "too nice"). If "ships to be sunk" did not radio off the sub's position, and if enemy hunter killer teams didn't destroy so many German Subs/Skippers/and crewmen; then the "Restricted" warfare would have cost the Germans nothing, and they would have and could have...continued.
Mini-Subs launched from mother ships; dive bombers, torpedo bombers, and fighters.
Two or more subs made up a wolf pack.
The Germans sunk more, cause the US didn't have many, and most of them were in the Pacific.
German subs are known as Unterseeboote, U-Bootefor short.
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.
Subs are for sinking ships.
