A "sister site" relationship has been established with Gregory Walker's
Trinity Site.
Greg and I are actively collaborating to provide the broadest variety of nuclear weapon information, in the most convenient form that we can. The two sites each have a different focus. The Nuclear Weapon Archive provides current information, technical data, and informative write-ups.
The Trinity Site focuses on historical information, especially reproductions of public domain documents.

• Updated the Tsar Bomba page (the world's largest nuclear bomb).
  

• Updated pages on the U.S. Nuclear Weapon Enduring Stockpile.
  

• Added Britain's First Plans for Developing an Atomic Bomb, William Penney's 1947 first outline of the features of the atomic bomb, and the tasks required to develop one.
  

• Updated the Section 8 of the Nuclear Weapons Frequently Asked Questions, "The First Nuclear Weapons", now with diagrams.
  

• Added the Enola Gay page.
  

• Updated pages on the U.S. Nuclear Weapon Enduring Stockpile, U.S. Nuclear Forces and the W62 and W76 warheads..
  

• Added pages on the Aleksandr Litivenko case and on polonium poisoning.
  

• Most recent update to North Korea.
  

• Added North Korea to the list of declared nuclear states.


• Updated U.S. nuclear arsenal page.

• Updated Operation Castle test page and Nuclear Weapons Frequently Asked Questions, Section 12. Contact email changed.

• Site is retitled The Nuclear Weapon Archive with its own domain.

  Regrettably a vast amount of reference material once available on-line has been removed in the wake of 9-11, and large amounts of material continue to disappear. For example, all informational sites at Los Alamos have vanished as of this writing (20 May 2002). I removed some links that are no longer active, but many others may be no longer available.
