Launch On Warning
Launch on warning (LOW), or fire on warning, is a strategy of nuclear weapon retaliation where a retaliatory strike is launched upon warning of enemy nuclear attack and while its missiles are still in the air, before detonation occurs. It gained recognition during the Cold War between the Soviet Union and the United States. With the invention of intercontinental ballistic missiles (ICBMs), launch on warning became an integral part of mutually-assured destruction (MAD) theory. US land-based missiles can reportedly be launched within 5 minutes of a presidential decision to do so and submarine-based missiles within 15 minutes. History Before the introduction of intercontinental ballistic missiles (ICBMs), the US Strategic Air Command (SAC) had multiple bombers on patrol at all times in a program known as Operation Chrome Dome. In the event of a Soviet nuclear strike, SAC would order its already-airborne bombers to fly to the other country and to drop their nuclear payload on p ...

Second Strike
In nuclear strategy, a retaliatory strike or second-strike capability is a country's assured ability to respond to a nuclear attack with powerful nuclear retaliation against the attacker. To have such an ability (and to convince an opponent of its viability) is considered vital in nuclear deterrence, as otherwise the other side might attempt to try to win a nuclear war in one massive Pre-emptive nuclear strike, first strike against its opponent's own nuclear forces. Theory The possession of second-strike capabilities counters a first-strike nuclear threat and can support a no first use nuclear strategy. Reciprocal second-strike capabilities usually cause a mutual assured destruction defence strategy, though one side may have a lower level minimal deterrence response. Second-strike capabilities can be further strengthened by implementing fail-deadly mechanisms. These mechanisms create a threshold and guaranteed consequences if that threshold is breached. For instance, a threshold m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nuclear Weapons
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either nuclear fission, fission (fission or atomic bomb) or a combination of fission and nuclear fusion, fusion reactions (thermonuclear weapon), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. Nuclear bombs have had Nuclear weapon yield, yields between 10 tons (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). Yields in the low kilotons can devastate cities. A thermonuclear weapon weighing as little as can release energy equal to more than 1.2 megatons of TNT (5.0 Petajoule, PJ). Apart from the blast, Effects of nuclear explosions, effects of nuclear weapons include Firestorm, firestorms, extreme Thermal radiation, heat and ionizing radiation, radioactive nuclear fallout, an Nuclear electromagnetic pulse, electromagnetic pulse, and a radar blackout. The first nuclear weapons were deve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Strategy
Nuclear strategy involves the development of military doctrine, doctrines and strategy, strategies for the production and use of nuclear weapons. As a sub-branch of military strategy, nuclear strategy attempts to match nuclear weapons as means to political ends. In addition to the actual use of nuclear weapons whether tactical nuclear weapon, in the battlefield or strategic nuclear weapon, strategically, a large part of nuclear strategy involves their use as a bargaining tool. Some of the issues considered within nuclear strategy include: *Conditions which serve a nation's interest to develop nuclear weapons *Types of nuclear weapons to be developed *How and when weapons are to be used Many strategists argue that nuclear strategy differs from other forms of military strategy. The immense and terrifying power of the weapons makes their use, in seeking victory in a traditional military sense, impossible. Perhaps counterintuitively, an important focus of nuclear strategy has be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doctor Strangelove
''Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb'' (known simply and more commonly as ''Dr. Strangelove'') is a 1964 political satire black comedy film co-written, produced, and directed by Stanley Kubrick. It is loosely based on the Thriller (genre), thriller novel ''Red Alert (novel), Red Alert'' (1958) by Peter George (author), Peter George, who wrote the screenplay with Kubrick and Terry Southern. It stars Peter Sellers in three roles. The film, financed and released by Columbia Pictures, was a co-production between the United States and the United Kingdom. ''Dr. Strangelove'' parodies Cold War fears of a Nuclear warfare, nuclear war between the United States and the Soviet Union and stars George C. Scott, Sterling Hayden, Keenan Wynn, Slim Pickens, and Tracy Reed (English actress), Tracy Reed. The story concerns an insane brigadier general of the United States Air Force who orders a pre-emptive nuclear attack on the Soviet Union. It follows the Presid ...

Stanislav Petrov
Stanislav Yevgrafovich Petrov (; 7 September 1939 – 19 May 2017) was a lieutenant colonel of the Soviet Air Defence Forces who played a key role in the 1983 Soviet nuclear false alarm incident. On 26 September 1983, three weeks after the Soviet military had shot down Korean Air Lines Flight 007, Petrov was the duty officer at the command center for the Oko nuclear early-warning system when the system reported that a missile had been launched from the United States, followed by up to four more. Petrov judged the reports to be a false alarm. His subsequent decision to disobey orders, against Soviet military protocol, is credited with having prevented an erroneous retaliatory nuclear attack on the United States and its NATO allies that would have likely resulted in a large-scale nuclear war. An investigation later confirmed that the Soviet satellite warning system had indeed malfunctioned. Because of his decision not to launch a retaliatory nuclear strike amid this incident, ...

Nash Equilibrium
In game theory, the Nash equilibrium is the most commonly used solution concept for non-cooperative games. A Nash equilibrium is a situation where no player could gain by changing their own strategy (holding all other players' strategies fixed). The idea of Nash equilibrium dates back to the time of Cournot, who in 1838 applied it to his model of competition in an oligopoly. If each player has chosen a strategy an action plan based on what has happened so far in the game and no one can increase one's own expected payoff by changing one's strategy while the other players keep theirs unchanged, then the current set of strategy choices constitutes a Nash equilibrium. If two players Alice and Bob choose strategies A and B, (A, B) is a Nash equilibrium if Alice has no other strategy available that does better than A at maximizing her payoff in response to Bob choosing B, and Bob has no other strategy available that does better than B at maximizing his payoff in response to Alice c ...

Mutually Assured Destruction
Mutual assured destruction (MAD) is a doctrine of military strategy and national security policy which posits that a full-scale use of nuclear weapons by an attacker on a nuclear-armed defender with second-strike capabilities would result in the complete annihilation of both the attacker and the defender. It is based on the theory of rational deterrence, which holds that the threat of using strong weapons against the enemy prevents the enemy's use of those same weapons. The strategy is a form of Nash equilibrium in which, once armed, neither side has any incentive to initiate a conflict or to disarm. The result may be a nuclear peace, in which the presence of nuclear weapons decreases the risk of crisis escalation, since parties will seek to avoid situations that could lead to the use of nuclear weapons. Proponents of nuclear peace theory therefore believe that controlled nuclear proliferation may be beneficial for global stability. Critics argue that nuclear proliferation i ...

Game Theory
Game theory is the study of mathematical models of strategic interactions. It has applications in many fields of social science, and is used extensively in economics, logic, systems science and computer science. Initially, game theory addressed two-person zero-sum games, in which a participant's gains or losses are exactly balanced by the losses and gains of the other participant. In the 1950s, it was extended to the study of non zero-sum games, and was eventually applied to a wide range of Human behavior, behavioral relations. It is now an umbrella term for the science of rational Decision-making, decision making in humans, animals, and computers. Modern game theory began with the idea of mixed-strategy equilibria in two-person zero-sum games and its proof by John von Neumann. Von Neumann's original proof used the Brouwer fixed-point theorem on continuous mappings into compact convex sets, which became a standard method in game theory and mathematical economics. His paper was f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fail-deadly
Fail-deadly is a concept in nuclear military strategy that encourages deterrence by guaranteeing an immediate, automatic, and overwhelming response to an attack, even if there is no one left to trigger such retaliation. The term ''fail-deadly'' was coined as a contrast to ''fail-safe''. Fail-deadly can refer to specific technology components, or the controls system as a whole. The United Kingdom's fail-deadly policies delegate strike authority to submarine commanders in the event of a loss of command (using letters of last resort), ensuring that even when uncoordinated, nuclear retaliation can be carried out.

Deterrence Theory
Deterrence theory refers to the scholarship and practice of how threats of using force by one party can convince another party to refrain from initiating some other course of action. The topic gained increased prominence as a military strategy during the Cold War with regard to the use of nuclear weapons and is related to but distinct from the concept of mutual assured destruction, according to which a full-scale nuclear attack on a power with second-strike capability would devastate both parties. The central problem of deterrence revolves around how to credibly threaten military action or nuclear punishment on the adversary despite its costs to the deterrer. Deterrence in an international relations context is the application of deterrence theory to avoid conflict. Deterrence is widely defined as any use of threats (implicit or explicit) or limited force intended to dissuade an actor from taking an action (i.e. maintain the status quo). Deterrence is unlike compellence, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
