What are Some Different Types of Nuclear Weapons?

Weapons that use the huge energy that can be released instantaneously by nuclear fission or fusion reactions to produce explosions and have the effect of mass destruction. It mainly includes fission weapons (first-generation nuclear weapons, usually called atomic bombs) and fusion weapons (also known as hydrogen bombs, divided into two-stage and three-stage). Nuclear weapons are also called nuclear or atomic weapons. In a broad sense, nuclear weapons refer to nuclear weapon systems with operational capabilities, including throwing or launching systems. Nuclear weapons usually refer to nuclear weapons in a narrow sense, that is, a nuclear bomb consisting of a nuclear warhead, guidance, and penetrating devices installed in the shell of the warhead. The main body of the nuclear warhead is a nuclear explosive device, referred to as a nuclear device. The nuclear device, together with the detonation control system, constitutes a nuclear warhead. The nuclear warhead, guidance, and penetrating equipment are installed in the warhead shell, which constitutes the nuclear warhead of a ballistic missile. Broadly defined nuclear weapons usually refer to nuclear weapons systems with operational capabilities, consisting of nuclear bombs, throwing / launching systems and command and control, communications, and operational support systems.

The emergence of nuclear weapons is

According to analysis by experts, the technical development of nuclear weapons in various countries must first pass four barriers: nuclear fuel, initiation devices, nuclear testing, and throwing technology.

In addition to the production of nuclear materials such as uranium 235 and plutonium 239, the development of the nuclear warhead itself must be coordinated with the development process of the entire nuclear weapon system. The research and development process is roughly as follows: starting from the imagination stage; after advance research or feasibility studies on key technical issues and components, several types of content including weight, size, form, power, nuclear materials, nuclear test requirements, development period, and funding are formed. Design plan; After demonstrative comparison and evaluation, design plan is selected, and tactical and technical indicators are determined; then model research and design, various simulation tests are carried out; process tests and trial productions, and the design of the design is verified through nuclear tests, and finally, Process sizing and approved production. To carry out these tasks, we must have a dedicated scientific and technical team and provide necessary test sites, including nuclear test sites. After the weapon is delivered to the army, the R & D and production departments must also provide maintenance, repair, and component replacement services, make necessary improvements based on the feedback information, and take charge of their retirement or processing.

To do a good job of designing a nuclear warhead, it is necessary to understand its reaction process thoroughly, understand the conditions and various physical parameters it must have, and grasp the internal relations and changes of many of these factors. To this end, a series of scientific and technological issues such as nuclear physics, neutron physics, high-temperature and high-pressure condensed matter physics, supersonic fluid mechanics, detonation, computational mathematics, and materials science must be studied. R & D practice will in turn drive and promote the development of these disciplines.

In the development process, the following links play an important role: Use a fast, large-capacity electronic computer to conduct theoretical research calculations of the reaction process. Such calculations should be as close to the actual situation as possible in order to find from a variety of assumptions or design schemes. Best

Due to the improvement of the accuracy of nuclear weapon projection tools, since the 1960s, the development of nuclear weapons, first of all, has significantly reduced the weight and size of the nuclear warhead but still maintained a certain power, that is, the specific power (ratio of power to weight) has Significantly improved. For example, the atomic bomb dropped by the United States in Nagasaki weighed about 4.5 tons and the power was about 20,000 tons; in the late 1970s,

On August 6, 2014, Japanese Prime Minister Shinzo Abe spoke at the memorial ceremony for those killed in the Hiroshima bombing, saying that the destruction of nuclear weapons around the world is a mission entrusted to Japan. He also reiterated Japan's three nuclear-free principles: do not own, manufacture, or import nuclear weapons.

Hiroshima Mayor Ichi Matsui read a declaration of peace calling for complete nuclear disarmament at a ceremony. He also called on the leaders of the nuclear powers, "First of all, Obama visits the bombed area in person and looks at it with his own eyes."

According to reports, Japan mourned the victims of the atomic bombing of Hiroshima on August 6, 1945. Traditionally, the commemorative ceremony was held in the Peace Park in the city centre. About 45 thousand people gathered at the ceremony, and diplomats from 65 countries also attended the ceremony. ^[8]

According to a January 7 issue of the Japanese "Diplomat Scholar" website, many countries are quietly searching for helium-3 materials for the fourth-generation nuclear weapons. Obtaining such non-radioactive sediments will become the new hegemon of the world. In the competition, we won.
