Nuclear submarines, such as those used by the navy, can stay at sea for 3-4 months without refueling. Their endurance is primarily limited by crew provisions and maintenance needs, rather than fuel supply.

FAQs & Answers

  1. What is the average lifespan of a nuclear submarine? The average lifespan of a nuclear submarine is typically about 30 years, depending on maintenance and upgrades.
  2. Can nuclear submarines be refueled at sea? No, nuclear submarines must return to port to be refueled, which is a planned part of their maintenance cycle.
  3. What are the main advantages of nuclear submarines? Nuclear submarines can operate submerged for extended periods and travel long distances without refueling, enhancing stealth and operational capability.
  4. How do crew provisions affect submarine endurance? Crew provisions, such as food and water, limit how long a submarine can stay at sea, as they must be stocked before deployment.
