Nuclear triad

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. Currently only four countries have the nuclear triad: United States, Russia, China and, recently, India. Israel is suspected of having it as well. In the past, France also had it, but renounced ground-launched missiles. While traditional nuclear strategy holds that a nuclear triad provides the best level of deterrence from attack, in reality, most nuclear powers do not have the military budget to sustain a full triad. While only the United States and Russia have maintained strong nuclear triads for most of the nuclear age, there are other countries that have triad powers. These countries include China, India, and France. Both the United States and Russia have had the strongest, and longest-living triads. These triads include the following components: Bomber aircraft: Aircraft carrying nuclear bombs, or nuclear-armed cruise missiles, for use against ground or sea targets. Land-based missiles (MRBMs or ICBMs): Delivery vehicles powered by a liquid or solid-fueled rocket that primarily travel in a ballistic (free-fall) trajectory. Ballistic missile submarines (SSBNs): Nuclear missiles launched from ships or submarines. They are classified under an umbrella of vessels and submarines that are capable of launching a ballistic missile. The triad gives countries a way to deliver a nuclear attack by land, sea or air. For the United States, the idea to have these three options was for the purpose of retaliation.
