I would be they all used them in WW2 or the cold war
Yes, they did.

Yes, submarines were used in World War I, primarily by Germany, which employed U-boats (Unterseeboote) to disrupt Allied shipping and trade routes. The use of unrestricted submarine warfare aimed to blockade Britain and cut off supplies. This tactic significantly impacted naval warfare and contributed to the eventual entry of the United States into the war. Other nations, including Britain and France, also utilized submarines, though to a lesser extent.
No, not really, submarines were first used successfully in the Civil War.
Britain, France, Germany, Italy and USA all used submarines during WW1
the military and navy use it for war and combat. Many submarines are made for launching missels and taking down ships and other subs.
The Allies, including Great Britain, USA, Russia and Italy all had submarines during WW1. In general they were not nearly as advanced or successful as the German U-boats.
