submarines in World War II

During World War II, submarines were stealthy naval vessels used primarily for attacking ships and disrupting enemy supply lines. Unlike surface ships, they operated submerged underwater for extended periods, making them hard to detect. German U-boats targeted Allied shipping in the Atlantic, threatening crucial supplies, while American and Allied submarines focused on Japanese ships in the Pacific. Submarines employed torpedoes as their main weapon, and their ability to strike silently gave them a strategic advantage. They played a vital role in naval warfare, shaping the outcome of the conflict by controlling sea routes and restricting enemy movements.
