About NuclearWeaponArchive

The Nuclear Weapon Archive is a website that collects information on nuclear weapons, their technical background, and their history. It covers the early history of atomic bombs, including the Manhattan Project, Trinity, Hiroshima and Nagasaki, and postwar weapons development. It also includes pages on the nuclear test series of several countries and on the arsenals of the declared nuclear states. A reference library holds technical articles on fission, fusion, weapon assembly methods and glossary terms, and the site hosts the Nuclear Weapons Frequently Asked Questions compiled by Carey Sublette.

The site is a sister site of the Trinity Site, which focuses on historical information and reproductions of public domain documents. The Nuclear Weapon Archive focuses on current information, technical data and written explanations. The homepage states that some sections are not yet completed or released, and that their links are inactive. Some reference items and site sections are dated from the late 1990s and early 2000s, so readers should check the dates on individual pages.
