How far could a submarine travel?

The distance a submarine can travel depends on various factors such as its type, fuel capacity, and mission requirements. Nuclear submarines can operate for extended periods, often traveling thousands of miles without needing to surface, while diesel-electric submarines typically have a limited range due to fuel constraints. On average, a nuclear submarine can cover approximately 20,000 miles before needing to refuel, while diesel-electric submarines may have ranges of 1,000 to 3,000 miles. Ultimately, operational factors and mission constraints will also influence the actual distance traveled.
