When was the first nuclear weapon created?
July 16, 1945
On July 16, 1945, in the desert north of Alamogordo, New Mexico, the first nuclear test took place, code-named “Trinity”, using a device nicknamed “the gadget.” The test, a plutonium implosion-type device, released energy equivalent to 22 kilotons of TNT, far more powerful than any weapon ever used before.
Who developed the first nuclear weapon?
J. Robert Oppenheimer
J. Robert Oppenheimer is often called the “father of the atomic bomb” for leading the Manhattan Project, the program that developed the first nuclear weapon during World War II.
When were nuclear weapons used in history?
The world’s first nuclear weapons explosion on July 16, 1945, in New Mexico, when the United States tested its first nuclear bomb. Not three weeks later, the world changed. On August 6, 1945, the United States dropped an atomic bomb on the Japanese city of Hiroshima.
How long did it take to develop the atomic bomb?
The Laboratory began in 1943, a few years after the start of World War II, for a single purpose: to design and build an atomic bomb. It took just 27 months. On July 16, 1945, the world’s first atomic bomb was detonated 200 miles south of Los Alamos at Trinity Site.
When was the last time a nuclear bomb was used?
During the final stages of World War II in 1945, the United States conducted atomic raids on the Japanese cities of Hiroshima and Nagasaki, the first on August 6, 1945, and the second on August 9, 1945. These two events were the only times nuclear weapons have been used in combat.
Where did the US get uranium for the atomic bomb?
Most of the uranium used during World War II was from the Congolese mines, and the “Little Boy” bomb the U.S. dropped on Hiroshima on August 6, 1945 used Congolese uranium. However, the transportation of uranium across the Atlantic Ocean was an arduous task. The journey needed to be quick and secretive.

When did the US drop its first nuclear bomb?
On August 6, 1945, during World War II (1939-45), an American B-29 bomber dropped the world’s first deployed atomic bomb over the Japanese city of Hiroshima.
When was the last US nuclear bomb set off?
This nuclear test’s code-name – Divider – was well-chosen (perhaps unwittingly), as it marked the last U.S. nuclear test to date. The 20 kilotons underground nuclear test, which was conducted at the test site in Nevada on 23 September 1992 , was the last of 1,032 nuclear tests carried out by the country.
What year did Russia first detonate a nuclear weapon?
First Soviet atomic bombThe Soviet Union detonated its first atomic bomb, known in the West as Joe-1, on Aug. 29, 1949, at Semipalatinsk Test Site, in Kazakhstan. Joe-1 was a direct copy of the plutonium bomb dropped on Nagasaki and had a yield of about 20 kilotons.
What is the most powerful weapon in the United States?
The B41 or Mk-41 with a yield of 25Mt is the most powerful thermonuclear weapon ever fielded by the United States. About 500 bombs were produced between 1960 and 1962, remaining in service, until July 1976.
