  • Sedan Crater Formation: On July 6, 1962, the largest man-made crater in the United States was formed. The underground nuclear test at the former Nevada Test Site was part of Operation Plowshare, a program established to investigate the use of nuclear weapons for mining, cratering and other civilian purposes.
  • Trinity The First Detonation of an Atomic Weapon: On July 16, 1945, the United States Army conducted the Trinity nuclear test plunging humanity into the atomic age. The first-ever nuclear bomb was detonated in New Mexico as part of the Manhattan Project.
  • “Baker” Bikini Atoll, The First Underwater Nuclear Explosion: On July 25,1946, the United States conducted the first-ever underwater nuclear explosion. Detonated at Bikini Atoll in the Pacific Ocean, the explosion was conducted to assess the damage to ships and submarines.
  • Little Feller I, The Last Atmospheric Test in the U.S.: On July 17, 1962, the United States conducted its final atmospheric nuclear test at the Nevada Test Site.
  • Strategic Arms Reduction Treaty Signed: The Strategic Arms Reduction Treaty (START) was signed on July 31, 1991, by former President George H.W. Bush and Soviet President Mikhail Gorbachev. The treaty limited the number of Intercontinental Ballistic Missiles and nuclear warheads either country could possess.
  • Atomic Energy Act of 1946: The Atomic Energy Act of 1946, also known as the McMahon Act, determined how the United States would control and manage nuclear technology. The act signed into law on August 1 ruled that nuclear weapon development and nuclear power management would be under civilian, rather than military control, and established the United States Atomic Energy Commission for this purpose.
  • The Limited Test Ban Treaty: On August 5, 1963, the Limited Test Ban Treaty was signed by the United States, Great Britain and the Soviet Union. The treaty banned nuclear weapons testing in the atmosphere, in outer space and under water.
  • Hiroshima Bombing: On August 6, 1945, during World War II, the United States detonated an atomic bomb over the Japanese city of Hiroshima. The explosion immediately killed an estimated 80,000 people.
  • Nagasaki Bombing: Days after the Hiroshima bombing, the United States dropped another atomic bomb on the Japanese city of Nagasaki, killing approximately another 40,000 people.
  • “Kearsarge” Joint Test Between U.S. and USSR: On August 17, 1988, the United States and the USSR conducted a joint verification experiment at the Nevada Test Site.
  • Nevada Test Site Renamed Nevada National Security Site: In August 2010, the Nevada Test Site was renamed the Nevada National Security Site (NNSS). The site is no longer used for nuclear weapons testing but rather for U.S. national security needs.
