Nuclear politics is back in a big way with intemperate tweets, cancelled non-proliferation agreements, summits and nuclear tests. Not since the Cold War has the threat of nuclear weapons been this obvious. Underlying this return to this politics of death is a simple fact — the risk of an intentional or accidental nuclear war has been threatening our lives and planet every day since

Nuclear weapons possess enormous destructive power from nuclear fission or combined fission and fusion reactions. Building on scientific breakthroughs made during the s, the United States, the United Kingdom and Canada collaborated during World War II, in what was called the Manhattan Project, to counter the suspected Nazi German atomic bomb project. The most comprehensive guide to nuclear weapons on the Internet.
Unsourced material may be challenged and removed. August Early weapons models, such as the " Fat Man " bomb, were extremely large and difficult to use.
Each modified bomber could only carry one such weapon and only within a limited range. After these initial weapons were developed, a considerable amount of money and research was conducted towards the goal of standardizing nuclear warheads so that they did not require highly specialized experts to assemble them before use, as in the case with the idiosyncratic wartime devices, and miniaturization of the warheads for use in more variable delivery systems.
Through the aid of brainpower acquired through Operation Paperclip at the tail end of the European theater of World War IIthe United States was able to embark on an ambitious program in rocketry. One of the first products of this was the development of rockets capable of holding nuclear warheads.
Because of their limited range, their potential use was heavily constrained they could not, for example, threaten Moscow with an immediate strike. The Boeing B Stratofortress was able by the mids to carry a wide arsenal of nuclear bombs, each with different capabilities and potential use situations.
Starting inthe U. This system was, however, tremendously expensive, both in terms of natural and human resources, and raised the possibility of an accidental nuclear war. During the s and s, elaborate computerized early warning systems such as Defense Support Program were developed to detect incoming Soviet attacks and to coordinate response strategies.
During this same period, intercontinental ballistic missile ICBM systems were developed that could deliver a nuclear payload across vast distances, allowing the U. Shorter-range weapons, including small tactical weapons, were fielded in Europe as well, including nuclear artillery and man-portable Special Atomic Demolition Munition.
The development of submarine-launched ballistic missile systems allowed for hidden nuclear submarines to covertly launch missiles at distant targets as well, making it virtually impossible for the Soviet Union to successfully launch a first strike attack against the United States without receiving a deadly response.
Improvements in warhead miniaturization in the s and s allowed for the development of MIRVs—missiles which could carry multiple warheads, each of which could be separately targeted. The question of whether these missiles should be based on constantly rotating train tracks to avoid being easily targeted by opposing Soviet missiles or based in heavily fortified silos to possibly withstand a Soviet attack was a major political controversy in the s eventually the silo deployment method was chosen.
MIRVed systems enabled the U. Additional developments in weapons delivery included cruise missile systems, which allowed a plane to fire a long-distance, low-flying nuclear-tipped missile towards a target from a relatively comfortable distance.
The current delivery systems of the U.
Additionally, in-flight refueling of long-range bombers and the use of aircraft carriers extends the possible range virtually indefinitely. Command and control[ edit ] Command and control procedures in case of nuclear war were given by the Single Integrated Operational Plan SIOP untilwhen this was superseded by Operations Plan This arrangement was seen as necessary during the Cold War to present a credible nuclear deterrent ; if an attack was detected, the United States would have only minutes to launch a counterstrike before its nuclear capability was severely damaged, or national leaders killed.
If the President has been killed, command authority follows the presidential line of succession. Changes to this policy have been proposed, but currently the only way to countermand such an order before the strike was launched would be for the Vice President and the majority of the Cabinet to relieve the President under Section 4 of the Twenty-fifth Amendment to the United States Constitution.
The command would be carried out by a Nuclear and Missile Operations Officer a member of a missile combat crewalso called a "missileer" at a missile launch control center. A two-man rule applies to the launch of missiles, meaning that two officers must turn keys simultaneously far enough apart that this cannot be done by one man.
When President Reagan was shot in there was confusion about where the "nuclear football" was, and who was in charge. In fact, the nuclear weapons were not placed under locks until decades later, so pilots or individual submarine commanders had the power, but not the authority, to launch nuclear weapons entirely on their own.
The United States nuclear program since its inception has experienced accidents of varying forms, ranging from single-casualty research experiments such as that of Louis Slotin during the Manhattan Projectto the nuclear fallout dispersion of the Castle Bravo shot into the accidental dropping of nuclear weapons from aircraft broken arrows.
How close any of these accidents came to being major nuclear disasters is a matter of technical and scholarly debate and interpretation.
In some of these cases such as Palomaresthe explosive system of the fission weapon discharged, but did not trigger a nuclear chain reaction safety features prevent this from easily happeningbut did disperse hazardous nuclear materials across wide areas, necessitating expensive cleanup endeavors.
Eleven American nuclear warheads are thought  to be lost and unrecovered, primarily in submarine accidents. The nuclear testing program resulted in a number of cases of fallout dispersion onto populated areas.
There were also instances during the nuclear testing program in which soldiers were exposed to overly high levels of radiation, which grew into a major scandal in the s and s, as many soldiers later suffered from what were claimed to be diseases caused by their exposures.
Many of the former nuclear facilities see next section produced significant environmental damages during their years of activity, and since the s have been Superfund sites of cleanup and environmental remediation. Deliberate attacks on weapons facilities[ edit ] Main article: Vulnerability of nuclear plants to attack In three hijackers took control of a domestic passenger flight along the east coast of the U.
The plane got as close as 8, feet above the site before the hijackers' demands were met. The National Nuclear Security Administration has acknowledged the seriousness of the Plowshares action.In Pakistan succeeded in denoting its first nuclear bomb some 24 years after India had conducted its first nuclear event in In the view of Pakistan, developing nuclear weapons and their delivery systems was absolutely necessary as a credible deterrent to a nuclear armed India.
Oct 20, · “This is the most severe crisis in nuclear arms control since the s,” said Malcolm Chalmers, the deputy director general of the Royal United Services Institute.
Jan 06, · More than two dozen countries have nuclear power, but only a few have nuclear weapons or are suspected of pursuing nuclear weapons.
Click on a country below to learn more about their nuclear programs. The United States became the world's first nuclear weapon state in , and remains the only state ever to have used a nuclear weapon in wartime. Today, it maintains one of the world's largest operational arsenals: approximately 4, warheads, 1, of which are deployed.
. The impact of nuclear weapons on sustainable development and humanity was one of the motivators of the Humanitarian Initiative on Nuclear Weapons meetings which eventually lead to the negotiation of the Treaty on the Prohibition of Nuclear Weapons in The world's first nuclear weapons explosion on July 16, , in New Mexico, when the United States tested its first nuclear bomb.
Not three weeks later, the world changed. On August 6, , the United States dropped an atomic bomb on the Japanese city of Hiroshima.
