Note: The classification of the 18 boats into the two U.S. Atlantic Fleet, and are thus based at Naval Submarine Base Kings Bay, Georgia. īoats in aqua(*) are operated by the U.S. Originally designed for 30-year service lives, it was later decided that Ohio-class submarines would each serve for 42 years, comprising two periods of 20 years of operations and a two-year mid-life nuclear refueling. The last boat of the class, USS Louisiana, was commissioned in September 1997, nearly 16 years after the class entered operational service. agreed to reduce the number of nuclear warheads it could deploy, and thus rationalized its order to 18 boats. Originally, it was decided that 20 boats were to be built, but due to the 1991 START I agreement between the U.S. Due to an unspecified "series of unfortunate problems in Washington D.C." and manufacturing issues, Ohio did not initiate sea trials until June 1981, setting back the boat's commissioning date to November that year, three years behind schedule. The first of the class, USS Ohio, was laid down in 1976. In July 1974, General Dynamics Electric Boat was awarded the contract to construct the Ohio-class submarines. Navy is currently, as of January 2013, undertaking a program tentatively named SSBN-X to study the prospective replacement of the class. With the first retirement of an Ohio-class boat scheduled for 2029, the U.S. The cost to refit the four boats was around US$1 billion (2008 dollars) per vessel. The boats could thereafter carry 154 Tomahawk cruise missiles and 66 special operations personnel, among other capabilities and upgrades. As a result, the four oldest boats of the class- Ohio, Michigan, Florida, and Georgia-progressively entered the conversion process in late 2002 and were returned to active service by 2008. The decision was made to convert four Ohio-class boats into SSGNs capable of conducting conventional land attack and special operations. Navy would be operating in total, 14 would be sufficient for the strategic needs of the U.S. In 1994, the Nuclear Posture Review study determined that, of the 18 Ohio SSBNs the U.S. Ohio-class submarines that carry ballistic missiles receive orders from the United States Strategic Command based in Nebraska. The primary self-defense weapon of the class is the Mk 48 ADCAP torpedo. The 73,000 lb (33,100 kg) UGM-96, with a range of 4,000 mi (6,400 km), served from October 1979, starting with the Benjamin Franklin-class USS Francis Scott Key, until 2006. Both variants of the Tridents-the UGM-96 Trident I and the UGM-133 Trident II-are propelled by three-stage solid propellant rockets and are equipped with 8–14 nuclear warheads. The Ohio class was designed in the 1970s to carry the concurrently-designed Trident submarine-launched ballistic missile. The Ohio class replaced the Benjamin Franklin- and Lafayette-class SSBNs. The Ohio-class boats, each displacing 18,750 tons submerged, are the third largest submarines in the world, behind the 48,000-ton Typhoon class and 24,000-ton Borei class of the Russian Navy. The remaining four have been converted from their initial roles as SSBNs to cruise-missile carriers (SSGN). Air Force strategic bombers and intercontinental ballistic missiles, constitute the nuclear-deterrent triad of the U.S. Fourteen of the eighteen boats are ballistic missile submarines (SSBN), which, along with U.S. Named after its lead boat, the Ohio class of nuclear-powered submarines is, as of October 2013, serving with its sole operator, the United States Navy. USS Louisiana, the last of the Ohio class, arrives at Naval Base Kitsap, Washington (2005). ![]()
