The duration a submarine can stay underwater varies based on its type and resources. Nuclear-powered submarines can stay submerged for several months, limited primarily by the crew's food supply and psychological factors. In contrast, diesel-electric submarines typically have a few days of underwater endurance before they need to surface or use a snorkel to recharge their batteries. Overall, the specific duration depends on the submarine's design and mission requirements.

You drag the word "submarine" itself onto the submarine. Then you wait for it to sink.
