The Manhattan Project was a research and development undertaking during World War II that produced the first nuclear weapons. It was led by the United States with the support of the United Kingdom and Canada.
Who created atomic bomb
physicist J. Robert Oppenheimer
No one person can be credited with producing the world's first atomic bomb but two men had outsize achievements in that effort: physicist J. Robert Oppenheimer and Army Lt. Gen. Leslie Groves.
What is the oldest bomb
Explosive bombs were used in East Asia in 1221, by a Jurchen Jin army against a Chinese Song city. Bombs built using bamboo tubes appear in the 11th century. Bombs made of cast iron shells packed with explosive gunpowder date to 13th century China.

city of Hiroshima
On August 6, 1945, the United States dropped an atomic bomb on the city of Hiroshima. The bomb was known as “Little Boy”, a uranium gun-type bomb that exploded with about thirteen kilotons of force.

Which country has largest atom bomb
Tsar Bomba, (Russian: “King of Bombs”) , byname of RDS-220, also called Big Ivan, Soviet thermonuclear bomb that was detonated in a test over Novaya Zemlya island in the Arctic Ocean on October 30, 1961. The largest nuclear weapon ever set off, it produced the most powerful human-made explosion ever recorded.
Do Tsar Bomba exist

Does Tsar Bomba still exist
As only one bomb was built to completion, that capability has never been demonstrated. The remaining bomb casings are located at the Russian Atomic Weapon Museum in Sarov and the Museum of Nuclear Weapons, All-Russian Scientific Research Institute Of Technical Physics, in Snezhinsk.
Why was the nuke called Little Boy
After the Thin Man bomb, whose moniker was inspired by the U.S. President Franklin Roosevelt, didn't come to fruition, the gun-type uranium atomic bomb named Little Boy was developed. It was likely dubbed as such because it was smaller in size.
Why didn’t the US nuke Vietnam
The most significant material constraint on using nuclear weapons was the risk of a wider war with China. U.S. leaders worried that a U.S. invasion of North Vietnam or the use of tactical nuclear weapons there could bring China into the war.
Does Japan have nukes
Since the bombing of Hiroshima and Nagasaki, Japan has been a staunch upholder of antinuclear sentiments. Its postwar Constitution forbids the establishment of offensive military forces, and in 1967 it adopted the Three Non-Nuclear Principles, ruling out the production, possession, or introduction of nuclear weapons.

The radiation in Hiroshima and Nagasaki today is on a par with the extremely low levels of background radiation (natural radioactivity) present anywhere on Earth. It has no effect on human bodies.
How big is Russia’s biggest nuke
Larger weapons will be more than 100 kilotons, and for strategic weapons, up to 1,000 kilotons. The bomb dropped on Hiroshima in 1945 was 15 kilotons. Russia's largest nuclear bomb, the Tsar Bomba, was tested in 1961 and is thought to have been some 50 megatons, or 50 million tons, of TNT.
Why didn’t the US use nuclear bombs in Vietnam
The most significant material constraint on using nuclear weapons was the risk of a wider war with China. U.S. leaders worried that a U.S. invasion of North Vietnam or the use of tactical nuclear weapons there could bring China into the war.
How many died on Tsar Bomba
The Tsar Bomba is the most powerful thermonuclear weapon ever detonated, as no other bomb as strong has ever been tested. While there were no deaths from the Tsar Bomba's test, there were windows shattered due to the explosion 780km (480 miles) away in a village on Dikson Island.
How powerful was Fat Man
21 kilotons
At 11:02 a.m., at an altitude of 1,650 feet, Fat Man (right) exploded over Nagasaki. The yield of the explosion was later estimated at 21 kilotons, 40 percent greater than that of the Hiroshima bomb. Nagasaki was an industrial center and major port on the western coast of Kyushu.
Who dropped the Fat Man bomb
Major Charles Sweeney
The atomic bomb used at Nagasaki, Japan, on August 9, 1945, was "Fat Man". The bomb was dropped by a USAAF B-29 airplane named "Bockscar", piloted by U.S. Army Air Force Major Charles Sweeney. The bomb weighed 10,000 pounds and had a diameter of 60 inches.
Did we almost nuke Vietnam
