Why were submarines important in the world war 2?

Answer 1

Submarines were crucial in World War II for their role in naval warfare, particularly in disrupting enemy supply lines through strategic blockades and attacks on merchant ships. The German U-boats targeted Allied shipping in the Atlantic, significantly impacting logistics and resource availability. Conversely, Allied submarines, especially in the Pacific, played a vital role in undermining Japanese naval strength and disrupting their supply chains. Their stealth and ability to operate underwater made them formidable tools in achieving naval supremacy.
