The Ohio class of nuclear-powered submarines includes the United States Navy's 14 ballistic missile submarines (SSBNs) and its four cruise missile submarines (SSGNs). Each displacing 18,750 tons submerged, the Ohio-class boats are the largest submarines ever built for the U.S. Navy. They are the world's third-largest submarines, behind the Russian Navy's Soviet-designed 48,000-ton Typhoon class and 24,000-ton Borei class. At 20 Trident II missiles apiece, Ohio-class boats carry just as many missiles, if not more, than either the Borei class or the recently deactivated Typhoon class (20).
A submarine-launched ballistic missile (SLBM) is a ballistic missile capable of being launched from submarines. Modern variants usually deliver multiple independently targetable reentry vehicles (MIRVs), each of which carries a nuclear warhead and allows a single launched missile to strike several targets. Submarine-launched ballistic missiles operate in a different way from submarine-launched cruise missiles.
The Dongfeng series, typically abbreviated as "DF missiles", are a family of short, medium, intermediate-range and intercontinental ballistic missiles operated by the Chinese People's Liberation Army Rocket Force.
A ballistic missile submarine is a submarine capable of deploying submarine-launched ballistic missiles (SLBMs) with nuclear warheads. The United States Navy's hull classification symbols for ballistic missile submarines are SSB and SSBN – the SS denotes submarine, the B denotes ballistic missile, and the N denotes that the submarine is nuclear powered. These submarines became a major weapon system in the Cold War because of their nuclear deterrence capability. They can fire missiles thousands of kilometers from their targets, and acoustic quieting makes them difficult to detect, thus making them a survivable deterrent in the event of a first strike and a key element of the mutual assured destruction policy of nuclear deterrence.
The People's Republic of China has developed and possesses weapons of mass destruction, including chemical and nuclear weapons. The first of China's nuclear weapons tests took place in 1964, and its first hydrogen bomb test occurred in 1967 at Lop Nur. Tests continued until 1996, when China signed the Comprehensive Nuclear-Test-Ban Treaty (CTBT), but did not ratify it. China acceded to the Biological Weapons Convention (BWC) in 1984 and ratified the Chemical Weapons Convention (CWC) in 1997.
The TN 75 is a French-built 150kt thermonuclear warhead used on France's M45 and M51 submarine-launched ballistic missiles, carried by the last of the Redoutable class submarines, S616 Inflexible, and by the Triomphant class submarines. The French Navy has 290 TN-75 warheads. It is a miniaturized, hardened and stealthy successor to the TN 71.
The UGM-133A Trident II, or Trident D5 is a submarine-launched ballistic missile (SLBM), built by Lockheed Martin Space in Sunnyvale, California, and deployed with the United States and Royal navies. It was first deployed in March 1990, and remains in service. The Trident II Strategic Weapons System is an improved SLBM with greater accuracy, payload, and range than the earlier Trident C-4. It is a key element of the U.S. strategic nuclear triad and strengthens U.S. strategic deterrence. The Trident II is considered to be a durable sea-based system capable of engaging many targets. It has payload flexibility that can accommodate various treaty requirements, such as New START. The Trident II's increased payload allows nuclear deterrence to be accomplished with fewer submarines, and its high accuracy—approaching that of land-based missiles—enables it to be used as a first strike weapon.
Naval Base Kitsap is a U.S. Navy base located on the Kitsap Peninsula in Washington state, created in 2004 by merging the former Naval Station Bremerton with Naval Submarine Base Bangor. It is the home base for the Navy’s fleet throughout West Puget Sound, provides base operating services, support for both surface ships and fleet ballistic missile and other nuclear submarines as one of the U.S. Navy's four nuclear shipyards, one of two strategic nuclear weapons facilities, and the only West Coast dry dock capable of handling a Nimitz-class aircraft carrier and the Navy's largest fuel depot. Naval Base Kitsap is the third-largest Navy base in the U.S.
The air-sol moyenne portée is a French nuclear air-launched cruise missile manufactured by MBDA France. In French nuclear doctrine, it is referred to as a "pre-strategic" weapon, the last-resort "warning shot" prior to a full-scale employment of strategic nuclear weapons launched from the Triomphant-class ballistic missile submarines. The missile's development was undertaken by Aérospatiale's Tactical Missile Division, now part of MBDA.
The Strategic Forces Command (SFC), sometimes called Strategic Nuclear Command, forms part of India's Nuclear Command Authority (NCA). It is responsible for the management and administration of the country's tactical and strategic nuclear weapons stockpile. It was created on 4 January 2003 by the Vajpayee Government. Air Marshal Teja Mohan Asthana became its first commander-in-chief.
The M51 SLBM is a French submarine-launched ballistic missile, built by ArianeGroup, and deployed with the French Navy. Designed to replace the M45 SLBM, it was first deployed in 2010.
The Hadès system was a short-range ballistic pre-strategic nuclear weapon system designed by France, as a last warning before use of strategic nuclear weapons, in the perspective of a Soviet invasion of Western Europe. It was designed from July 1984 as a replacement for the tactical road-mobile Pluton missile. Initially 120 missiles were planned to be deployed.
The R-29RM Shtil was a liquid propellant, submarine-launched ballistic missile in use by the Russian Navy. It had the alternate Russian designations RSM-54 and GRAU index 3M27. It was designed to be launched from the Delta IV submarine, each of which is capable of carrying 16 missiles. The R-29RM could carry four 100 kiloton warheads and had a range of about 8,500 kilometres (5,300 mi). They were replaced with the newer R-29RMU2 Sineva and later with the enhanced variant R-29RMU2.1 Layner.
The W71 nuclear warhead was a US thermonuclear warhead developed at Lawrence Livermore National Laboratory in California and deployed on the LIM-49A Spartan missile, a component of the Safeguard Program, an anti-ballistic missile (ABM) defense system briefly deployed by the US in the 1970s.
A nuclear triad is a three-pronged military force structure that consists of land-launched nuclear missiles, nuclear-missile-armed submarines, and strategic aircraft with nuclear bombs and missiles. Specifically, these components are land-based intercontinental ballistic missiles (ICBMs), submarine-launched ballistic missiles (SLBMs), and strategic bombers. The purpose of having this three-branched nuclear capability is to significantly reduce the possibility that an enemy could destroy all of a nation's nuclear forces in a first-strike attack. This, in turn, ensures a credible threat of a second strike, and thus increases a nation's nuclear deterrence.
The TN 70 is a French-built thermonuclear warhead which was used on submarine-launched ballistic missiles in Redoutable class ballistic missile submarines.
The Novator RK-55 Relief is a Russian Navy cruise missile that is launched either from submarines (SLCM) or from surface ships. It can have a nuclear warhead developed in the Soviet Union. A version launched from submarine torpedo tubes, the S-10 Granat, has apparently been converted to carry conventional warheads and continues in service to this day. The Russian Federation was reported to have deployed the derivative SS-CX-7/SS-CX-8 systems on 14 February 2017. The land launched version is called the Novator 9M729.
The S3 was a French land-based Intermediate Range Ballistic Missile, equipped with a single 1.2-megatonne thermonuclear warhead. In France it is called an SSBS, for Sol-Sol Balistique Stratégique, or Ground-Ground Strategic Ballistic Missile.
Tête nucléaire océanique is a French thermonuclear warhead intended for use on the M51.2 submarine-launched ballistic missile, that is being developed and built by the Division of Military Applications (DAM) at France's Commissariat à l'énergie atomique et aux énergies alternatives. It will be carried on Triomphant-class submarines. The TNO is intended to replace the currently deployed TN 75 warhead. Its commissioning was planned for 2015, when France's newest submarines, either Le Terrible or Le Vigilant, will be one of the first to carry the warhead.
