Saednews: Submarines, as one of the most complex and advanced military and research tools, utilize a range of innovative technologies that enable them to continue their missions in the depths of the sea.
Saednews Report: Submarines are among the vehicles that, due to their ability to move underwater and carry out special missions, hold significant importance. These vehicles have become unparalleled tools by utilizing advanced technologies in various fields, including propulsion, navigation systems, communications, sensors, and defense systems. This article examines some of the most important technologies used in submarines, enabling these vehicles to perform optimally in the harsh and difficult underwater conditions.
Submarines, as one of the most complex and advanced vehicles in the underwater world, use various technologies to perform a variety of functions, including moving in the depths of the sea, gathering information, and carrying out specific missions. Below are some of the most important technologies used in submarines:
Propulsion and Engine Systems Submarines typically use diesel or nuclear engines for movement.
Nuclear Propulsion: Nuclear-powered submarines use nuclear energy to generate electricity and propel the submarine. This system allows them to remain underwater for long periods without the need for refueling.
Diesel-Electric Propulsion: In diesel-electric submarines, a diesel engine generates electricity, which powers the electric motors that provide the necessary movement. These submarines can only move underwater for short periods.
Depth Control and Buoyancy Systems Submarines use complex systems to maintain balance and control depth:
Ballast Tanks: Submarines use ballast tanks to control depth, adjusting their buoyancy by filling or emptying these tanks with water or air.
Automatic Depth Control Systems: More advanced submarines use automated systems to precisely adjust and maintain their depth.
Navigation and Positioning Systems Submarines need precise navigation systems for movement:
Acoustic Systems (Sonar): Submarines use sonar to detect underwater objects and obstacles. This system sends sound waves and receives their echoes to determine the location and distance of obstacles.
Inertial Navigation Systems (INS): These systems help submarines determine their position underwater without relying on satellite signals.
GPS with Special Underwater Adjustments: Surface or near-surface submarines use GPS for positioning, but at great depths, these signals are not detectable.
Communication Systems Submarines need to communicate with other submarines or coastal bases. For this purpose, special systems are used:
Acoustic Communication Systems: Since radio waves cannot transmit underwater, acoustic communication systems are used to exchange information through sound waves.
Communication Through Cables: Submarines may use special cables to send information to the surface and receive orders.
Sensors and Cameras Submarines are equipped with various advanced sensors and cameras for environmental data collection and target identification:
Underwater Cameras: Used for observing the underwater environment and identifying obstacles or targets.
Chemical and Biological Sensors: Used to detect pollutants or assess environmental conditions underwater.
Thermal Imaging Systems: Used to detect the temperature of water and objects in specific conditions.
Defense Systems and Weaponry Military submarines are equipped with advanced defense systems:
Missiles and Torpedoes: Submarines can act as platforms for launching missiles and torpedoes.
Anti-Ship and Anti-Submarine Systems: Used for self-defense against enemy threats.
Energy Storage Systems Submarines need to store energy to power their systems during missions:
Lithium-Ion Batteries: In diesel-electric submarines, rechargeable batteries play an essential role in storing and providing energy.
Fuel Cells: Some submarines use fuel cells to generate electricity, which provides better performance than traditional battery systems.
Security and Protection Systems To protect submarines and their crew in harsh conditions, multiple security systems are in place:
Waterproof Doors: Inside submarines, doors are installed that prevent water from entering other sections in case of leaks.
Monitoring Systems for Technical Status: Submarines have advanced systems to monitor the status of engines, electrical systems, and other components.
These technologies allow submarines to perform optimally in challenging environmental conditions, such as great depths and high pressures, ensuring they can continue their missions effectively and safely.
