The Mediterranean U-boat Campaign in the Mediterranean Sea was fought by Austria-Hungary and German Empire against the Allies during World War I. It was characterised by the ability of the Central Powers to raid with near impunity during the first years of the war, causing substantial shipping losses, until the introduction of the convoy system allowed the Allies to drastically cut their losses from 1917 on.

The U-boat campaign from 1914 to 1918 was the World War I naval campaign fought by German U-boats against the trade routes of the Allies. It took place largely in the seas around the British Isles and in the Mediterranean. The German Empire relied on imports for food and domestic food production and the United Kingdom relied heavily on imports to feed its population, and both required raw materials to supply their war industry; the powers aimed, therefore, to blockade one another. The British had the Royal Navy which was superior in numbers and could operate on most of the world's oceans because of the British Empire, whereas the Imperial German Navy surface fleet was mainly restricted to the German Bight, and used commerce raiders and unrestricted submarine warfare to operate elsewhere.

The Torpedo Alley, or Torpedo Junction, off North Carolina, is one of the graveyards of the Atlantic Ocean, named for the high number of attacks on Allied shipping by German U-boats in World War II. Almost 400 ships were sunk, mostly during the Second Happy Time in 1942, and over 5,000 people were killed, many of whom were civilians and merchant sailors. Torpedo Alley encompassed the area surrounding the Outer Banks, including Cape Lookout and Cape Hatteras.
United States Navy operations during World War I began on April 6, 1917, after the formal declaration of war on the German Empire. The United States Navy focused on countering enemy U-boats in the Atlantic Ocean and the Mediterranean Sea while convoying men and supplies to France and Italy. Because of United States's late entry into the war, her capital ships never engaged the German fleet and few decisive submarine actions occurred.
