What do the guys on a submarine do during long missions?
Submarines can operate at depths of over 1,000 feet, where water pressure exceeds 1,000 psi, a condition that requires specialized materials and engineering to prevent structural failure.
Crew members on submarines typically work in shifts, known as "watches," allowing them to alternate between operational duties and rest periods, which is crucial for maintaining mental acuity in confined environments.
Submarines are equipped with advanced sonar systems to navigate and detect other vessels, utilizing sound waves to map the ocean floor and identify potential obstacles or threats.
The atmosphere inside a submarine is carefully controlled, with systems to manage oxygen levels and carbon dioxide concentration, essential for the crew's survival during long missions.
To maintain morale during extended deployments, submariners often engage in recreational activities, such as watching movies, playing video games, or even exercising, all within the limited space of the submarine.
Food on submarines is stored in a way that minimizes waste and maximizes preservation, often using freeze-drying and vacuum-sealing techniques to ensure meals remain edible for months.
Submarines use a system called "ballast tanks" to control their buoyancy, allowing them to sink or rise in the water column by taking in or expelling water.
The psychological effects of prolonged underwater missions can lead to phenomena such as "submarine stress," which is managed through regular mental health check-ins and team-building exercises.
Submarines are often equipped with a "periscope," which uses a system of mirrors and lenses to allow crew members to observe the surface while remaining submerged, providing a tactical advantage.
Many modern submarines utilize a nuclear propulsion system, which allows them to operate underwater for extended periods without needing to surface for fuel, significantly increasing their operational range.
The crew on submarines undergoes rigorous training in emergency procedures, including how to react to flooding or fire, ensuring they are prepared to handle life-threatening situations in a confined space.
Submarines have a unique waste management system that treats and processes human waste on board, reducing the need to surface and dispose of it, which could compromise stealth.
Communication with the outside world is limited on submarines, typically relying on very low frequency (VLF) radio waves that can penetrate water, though this is often restricted to urgent messages.
The hull of a submarine is designed to be hydrodynamic, allowing it to move efficiently through water and reducing drag, which is necessary for stealth and fuel efficiency.
Some submarines are equipped with advanced artificial intelligence systems that assist in navigation, threat detection, and data analysis, enhancing operational capabilities.
Crew members often train in simulators that replicate the submarine's environment, allowing them to practice emergency drills and operational procedures without the risks associated with real-life scenarios.
Submarine missions can last several months, during which crew members may experience a phenomenon known as "time dilation," where the extended confinement alters their perception of time.
The design and operation of submarines are influenced by principles of fluid dynamics, which dictate how they interact with water, affecting everything from speed to maneuverability.
Research submarines contribute to scientific knowledge by exploring underwater ecosystems, studying marine life, and collecting data on oceanographic phenomena, often leading to discoveries about climate change.
Finally, the technologies developed for submarines often find applications in other fields, such as robotics, deep-sea exploration, and even space exploration, showcasing the innovative engineering behind these remarkable vessels.
