Intro
Discover the 5 key features of Permit-class submarines, the United States Navys attack submarine class, including their nuclear-powered propulsion, advanced sonar systems, and combat capabilities. Learn about their designs, developments, and operations, and explore how these submarines play a crucial role in naval warfare, stealth, and reconnaissance.
The Permit class submarines were a class of nuclear-powered attack submarines in service with the United States Navy from the 1960s to the 1990s. These submarines were designed to conduct a variety of missions, including anti-submarine warfare, anti-surface warfare, and reconnaissance. Here are 5 key features of Permit class submarines:
Advanced Propulsion System
The Permit class submarines were powered by a nuclear reactor, which provided a significant improvement in endurance and speed compared to conventional diesel-electric submarines. The nuclear reactor was a pressurized water reactor (PWR) design, which was more efficient and reliable than earlier nuclear reactor designs. The reactor was paired with a steam turbine, which drove a single propeller shaft.
The advanced propulsion system of the Permit class submarines allowed them to operate at high speeds for extended periods of time, making them well-suited for a variety of missions. The submarines had a top speed of over 20 knots (23 mph), which was faster than many surface ships of the time.
Improved Sensors and Fire Control Systems
The Permit class submarines were equipped with advanced sensors and fire control systems, which allowed them to detect and engage targets more effectively. The submarines had a bow-mounted sonar system, which used active and passive sensors to detect and track targets. The sonar system was paired with a fire control system, which used computers and gyroscopes to calculate the optimal firing solution.
The submarines also had a radar system, which provided air and surface surveillance capabilities. The radar system was used to detect and track surface ships and aircraft, and to provide targeting data for the submarine's missiles and torpedoes.
Increased Endurance and Range
The Permit class submarines had a significant increase in endurance and range compared to earlier submarine designs. The submarines had a large battery capacity, which allowed them to operate for extended periods of time without surfacing. The submarines also had a large fuel capacity, which allowed them to operate for thousands of miles without refueling.
The increased endurance and range of the Permit class submarines made them well-suited for long-range missions, such as patrols and reconnaissance. The submarines could operate for weeks or even months at a time without surfacing, making them ideal for covert operations.
Advanced Communication Systems
The Permit class submarines had advanced communication systems, which allowed them to communicate with other submarines and surface ships over long distances. The submarines had a satellite communication system, which used satellites to transmit and receive messages. The system allowed the submarines to communicate with other submarines and surface ships in real-time, even when they were thousands of miles apart.
The submarines also had a radio communication system, which used radio waves to transmit and receive messages. The system allowed the submarines to communicate with other submarines and surface ships over shorter distances, and was used for tactical communications during missions.
Improved Safety Features
The Permit class submarines had several safety features, which improved the safety of the crew and the submarine. The submarines had a emergency ballast tank system, which allowed them to quickly surface in case of an emergency. The system used compressed air to blow water out of the ballast tanks, which allowed the submarine to quickly gain buoyancy and surface.
The submarines also had a fire suppression system, which used inert gases to suppress fires. The system was designed to quickly extinguish fires, which reduced the risk of damage to the submarine and injury to the crew.
