U Boat
A U-boat is a type of submarine used by the German Navy, particularly during World War I and World War II. The term "U-boat" comes from the German word "Unterseeboot," which means "undersea boat." These vessels were primarily designed for stealthy underwater warfare, targeting enemy ships and disrupting supply lines.
U-boats played a significant role in naval battles, employing tactics like wolfpack attacks, where multiple submarines would coordinate to overwhelm enemy convoys. Their effectiveness led to significant losses for the Allies, but advancements in anti-submarine warfare eventually diminished their impact by the end of the war.
