During World War I, the U.S. Navy expanded eightfold and played a vital role in the Allied war effort, primarily by focusing on antisubmarine operations and logistics rather than engaging in major sea battles.1
Key contributions included:
- Antisubmarine Warfare: Upon entering the war in 1917, the U.S. Navy shifted its focus from battleship construction to building destroyers and submarine chasers to protect Allied shipping from German U-boats. By July 1917, U.S. destroyers were stationed in Ireland to support the British convoy system, and by the war's end, more than 380 U.S. craft were operating overseas.2
- Minefields: The Navy laid an extensive antisubmarine minefield across the North Sea.1
- Fleet Support: A battleship division joined the British Grand Fleet, while another was sent to Bantry Bay to guard against German surface raiders.1
- Logistics and Combat Support: The Navy transported more than 2,000,000 troops to France, deployed a naval aviation bombing squadron, and provided heavy railway-mounted guns for use on the Western Front.1
