Nuclear Weapons Primer Learn about the steps and materials needed to make a nuclear weapon, a description of weapon designs, and a history of nuclear weapon tests.

Most known innovations in nuclear weapon design originated in the United States, though some were later developed independently by other states. In early news accounts, pure fission weapons were …

Feb 18, 2026 · The simplest weapon design is the pure fission gun-assembly device, in which an explosive propellant is used to fire one subcritical mass down a “gun barrel” into another subcritical …

Jun 4, 2025 · Ever wondered how a nuclear bomb is actually made? In this in-depth video, we explore the entire process of building a nuclear weapon — from uranium enrichment to triggering the final...

Understand the scientific, industrial, and political processes required to develop nuclear weapons.

Mar 13, 2019 · Admittedly, the situation with respect to terrorist acquisition of weapons is a bit different. But even here, actual weapon construction requires a type of information I do not provide, and …

Nov 30, 2017 · After testing a missile that North Korea said was capable of striking the US, Pyongyang claimed it had become a full nuclear power, though analysts remain skeptical. Following are the …

At first glance, making a fission bomb is simple: assemble a supercritical mass of fissile material, and a chain reaction will rapidly produce neutrons that, in turn, generate more fission and neutrons.

Jul 18, 2009 · The amount of fissile materials needed to make a nuclear weapon varies with the degree of enrichment, the sophistication of the weapon design, and the intended yield.

Key materials in this process include uranium and plutonium, which are extracted and processed through various stages, including mining, milling, and chemical separation. Facilities like the Pantex …
