In the upper level of the forward compartment is theĬontrol room-the heart of the ship. The propulsion plant and other shipboard use. Service Turbine Generators that supply the ship'sĮlectricity, and the evaporator, which distills water for The after compartmentĪll the propulsion machinery, as well as the Ship's Living spaces, weapons systems, control centers, and The ship carries enough food to feed a crew of over one hundred for as long as 90 days.Ĭlass submarines are divided into two watertightĬompartments. Sustained operation of the complex equipment and machinery on the ship requires the support of repair parts carried on board. The ship is equipped with two distilling plants which convert salt water to fresh water for drinking, washing and the propulsion plant. Atmosphere control equipment replenishes oxygen used by the crew, and removes carbon dioxide and other atmosphere contaminants. To take advantage of this, the ship is outfitted with auxiliary equipment to provide for the needs of the crew. The nuclear power plant gives these boats the ability to remain deployed and submerged for extended periods of time.
Various alarm and indicating circuits enable the Officer of the Deck and the Engineering Officer of the Watch to continuously monitor critical parameters and equipment located throughout the ship. Interior communication is possible on a wide range of circuits and sound powered phones which do not require electrical power and are reliable in battle situations. The submarines are outfitted with a wide variety of antennas, transmitters and receivers necessary to support accomplishment of their assigned tasks. The USS MEMPHIS (SSN 691) has been modified to serve as a test and evaluation platform for advanced submarine systems and equipment, while retaining her combat capability.
They are configured for under-ice operations in that their forward diving planes have been moved from the sail structure to the bow and the sail has been strengthened for breaking through ice. SSNs 751-773 - The final 23 hulls referred to as "688I" (for improved), are quieter, incorporate an advanced BSY-1 sonar suite combat system and the ability to lay mines from their torpedo tubes.SSNs 719-750 - Starting with SSN 719 and beyond the last 31 hulls of the class have 12 vertical launch tubes for the Tomahawk cruise missile, along with an upgraded reactor core.SSNs 688-718 - Original Los Angeles class.These submarines were built in three successive variants: Faster than her predecessors and possessing highly accurate sensors, weapons control systems and central computer complexes, the LOS ANGELES Class is armed with sophisticated MK-48 Advanced Capability anti-submarine/ship torpedoes, Tomahawk land attack cruise missiles, and mines. These 360 foot, 6,900-ton ship are well equipped to accomplish these tasks. Get on station quickly, stay for an extended period of time and carry out a variety of missions including the deployment of special forces, minelaying, and precision strike land attack. While anti-submarine warfare is still their primary mission, the inherent characteristics of the submarine's stealth, mobility and endurance are used to meet the challenges of today's changing global geopolitical climate. Submarines of the LOS ANGELES Class are among the most advanced undersea vessels of their type in the world. Escort duties included conducting ASW sweeps hundreds of miles ahead of the CVBG and conducting attacks against the SAG.
The new submarines showed another step improvement in quieting and an increase in operating speed to allow them to support the CVBG. The LOS ANGELES class SSN was designed almost exclusively for Carrier Battlegroup escort they were fast, quiet, and could launch Mk48 and ADCAP torpedoes, Harpoon Anti-Ship Missiles (no longer carried), and both land attack and anti-ship (no longer carried) Tomahawk cruise missiles. The LOS ANGELES class SSN specifically included ASW against Soviet submarines trying to sink the USĬarrier and ASUW against capital ships in the Soviet surface action group.
