The SSN 688 class submarines, also known as the Los Angeles-class submarines, are a class of nuclear-powered attack submarines used by the United States Navy. Here are 10 cool facts about these impressive vessels:
Design and Development
The Los Angeles-class submarines were designed to replace the older SSN 585 and SSN 637 classes. The first submarine of this class, USS Los Angeles (SSN-688), was commissioned in 1976. A total of 62 submarines were built, with the last one, USS Cheyenne (SSN-773), commissioned in 1996.
Streamlined Hull Design
The Los Angeles-class submarines have a streamlined hull design, which allows them to operate at high speeds and reduce their acoustic signature. This design also enables them to dive to depths of over 800 feet.
Propulsion and Power
The Los Angeles-class submarines are powered by a single S6G reactor, which produces 35,000 horsepower. This power is used to drive a single shaft, which is connected to a propeller. The submarines also have a backup diesel generator, which can be used in case of an emergency.
Advanced Propulsion System
The Los Angeles-class submarines have an advanced propulsion system, which includes a flywheel-based propulsion system. This system allows the submarines to operate at high speeds while reducing their noise signature.
Armament and Sensors
The Los Angeles-class submarines are equipped with a variety of armaments, including:
- 4 x 21-inch torpedo tubes
- 1 x Harpoon missile launcher
- 1 x Tomahawk missile launcher
- 1 x Mk 48 torpedo
The submarines also have advanced sensors, including:
- AN/BSY-1 combat system
- AN/BQQ-5 sonar system
- AN/BQR-15 sonar system
- AN/BRD-7 radio direction finder
Advanced Sonar System
The Los Angeles-class submarines have an advanced sonar system, which includes a bow-mounted sonar array and a towed sonar array. This system allows the submarines to detect and track targets at long range.
Crew and Accommodations
The Los Angeles-class submarines have a crew of 13 officers and 121 enlisted personnel. The submarines have a variety of accommodations, including:
- Crew quarters
- Galley (kitchen)
- Mess hall
- Sick bay
- Laundry facilities
Advanced Crew Quarters
The Los Angeles-class submarines have advanced crew quarters, which include private sleeping quarters for officers and enlisted personnel. The submarines also have a gym and a library.
Operational History
The Los Angeles-class submarines have had a long and distinguished operational history. They have been involved in a variety of operations, including:
- Cold War operations
- Gulf War operations
- War in Afghanistan operations
- War in Iraq operations
Notable Operations
The Los Angeles-class submarines have been involved in several notable operations, including:
- Operation Earnest Will
- Operation Desert Storm
- Operation Enduring Freedom
- Operation Iraqi Freedom
Modernization and Upgrades
The Los Angeles-class submarines have undergone several modernization and upgrade programs over the years. These programs have included:
- Installation of new combat systems
- Upgrades to the sonar system
- Installation of new propulsion systems
- Upgrades to the hull and superstructure
Advanced Combat System
The Los Angeles-class submarines have been equipped with an advanced combat system, which includes a new combat management system and a new sonar system.
Conclusion
The Los Angeles-class submarines are a class of highly advanced and capable attack submarines. With their streamlined hull design, advanced propulsion system, and advanced sensors and armaments, they are well-suited to a variety of operational tasks. Their long and distinguished operational history is a testament to their capabilities and versatility.
