Hiroshima

Hiroshima was the first military target of a nuclear weapon in human history. This occurred on August 6, 1945 in the Pacific theatre of World War 2, at 8:15 a.m., when the United States Army Air Forces (USAAF) dropped the atomic bomb "Little Boy" on the city.

Hiroshima - Wikipedia

, Japan, August 6, 1945, at 8:15 AM. A B-29 dropped the bomb from 31,000 feet. The bomb exploded about 1,500 feet above the city with a force of 15,000 tons of TNT.

Did Little Boy hit the ground?

Little Boy was a uranium bomb packed with about 110 pounds of fissile material. As it turned out, less than 2 pounds of that material actually underwent fission. The bomb never hit the ground, but exploded about 2,000 feet above the city – a height intended to cause maximum damage.

Was Fat Man and Little Boy more powerful?

The Fat Man produced an explosion of about 21 kilotons. The B83? 1.2 megatons, equaling 1,200,000 tons of TNT, making it 80 times more powerful than the Little Boy.

What was the blast range of Little Boy?

Its lethal radius was approximately 1.3 kilometres (0.8 mi), covering about half of the firestorm area. An estimated 30% of immediate fatalities were people who received lethal doses of this direct radiation, but died in the firestorm before their radiation injuries would have become apparent.

How big was the Little Boy nuke?

The atomic bomb used at Hiroshima, Japan, on August 6, 1945, was "Little Boy". The bomb was dropped by a USAAF B-29 bomber, Enola Gay, piloted by U.S. Army Air Force Colonel Paul Tibbets, Jr. The bomb weighed 9,000 pounds and had a diameter of only 28 inches.

How was the LITTLE BOY Atomic Bomb Works?.Hiroshima bombing | 3D Animation. Learn from the base.

What is the biggest bomb ever made in size?

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.

What is the smallest nuke ever made?

The W54 fission bomb, deployed by the USA in Europe between 1961 and 1971, is the smallest confirmed nuclear weapon ever made.

How fast did Little Boy explode?

0916:02 (8:16:02 AM Hiroshima time): After falling nearly six miles in forty-three seconds, Little Boy explodes 1,968 feet above the Dr. Shima's Clinic, 550 feet away from the aiming point of the Aioi Bridge.

What was the wind speed of the Little Boy bomb?

Also, the intensive bomb blast created maximum wind speeds of 440 meters per second at the hypocenter. The blast spread out radially, and swept the entire city in about 10 seconds. August 6,1945-8:15 a.m. Characteristics―The mass destruction and killing was indiscriminate and instantaneous.

Did Little Boy bomb have a parachute?

For some time after the atomic bombings, the Japanese public referred to the new-type bomb as a “parachute bomb,” but, needless to say, no parachute was attached to the atomic bomb.

Are parts of Hiroshima still radioactive?

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.

What is the strongest bomb in the world?

The Tsar Bomba packed a punch of over 50 megatons, which is the equivalent of 50 million tons of conventional explosives. That's 10 times more powerful than all the munitions expended during World War Two and over 1,500 times the force of the atomic bombs dropped on Hiroshima and Nagasaki combined.

How far was the shock wave at Hiroshima?

In both cities the blast totally destroyed everything within a radius of 1 mile from the center of explosion, except for certain reinforced concrete frames as noted above. The atomic explosion almost completely destroyed Hiroshima's identity as a city.

How much uranium did Little Boy have?

About 140 pounds (64 kilograms) of highly enriched uranium-235 was used to create "Little Boy," a nuclear-fission bomb that worked by shooting a large, hollow cylinder of uranium over a smaller uranium insert.

Why did Little Boy explode in the air?

Little Boy triggered a nuclear explosion, rather than implosion, by firing one piece of uranium 235 into another. When enough U235 is brought together, the resulting fission chain reaction can produce a nuclear explosion.

Was Little Boy detonated in the air?

The Mk I bomb, nicknamed "Little Boy," was the first nuclear weapon used in warfare. It was delivered by the B-29 Enola Gay (on display at the Smithsonian National Air & Space Museum), it detonated at an altitude of 1,800 feet over Hiroshima, Japan, on Aug. 6, 1945.

What was used as fuel in the Little Boy bomb?

The first two atomic bombs in 1945

The Hiroshima bomb was made from highly-enriched uranium-235. This was prepared by diffusion enrichment techniques using the very small differences in mass of the two main isotopes: U-235 (originally 0.7% in the uranium) and U-238, the majority.

What is the fastest wind has ever blown?

The fastest wind speed ever recorded comes from a hurricane gust. On April 10, 1996, Tropical Cyclone Olivia (a hurricane) passed by Barrow Island, Australia. It was the equivalent of a Category 4 hurricane at the time, 254 mph (408 km/h).

How many miles would a nuke destroy?

The volume the weapon's energy spreads into varies as the cube of the distance, but the destroyed area varies at the square of the distance. Thus 1 bomb with a yield of 1 megaton would destroy 80 square miles. While 8 bombs, each with a yield of 125 kilotons, would destroy 160 square miles.

How far did Hiroshima radiation spread?

Nearly everything was heavily damaged up to a radius of 3 miles from the blast, and beyond this distance damage, although comparatively light, extended for several more miles.

How far would a nuke reach if it hit Washington DC?

The fireball would have a radius of 180miles, the air blast radius would be 340miles, and the radiation radius - where death rates would be between 50 percent and 90 percent - would be 1.2kilometers.

Can 1 nuke take out the whole world?

A single nuclear weapon can destroy a city and kill most of its people. Several nuclear explosions over modern cities would kill tens of millions of people. Casualties from a major nuclear war between the US and Russia would reach hundreds of millions.

How old is the oldest nuke?

The world's first nuclear explosion occurred on July 16, 1945, when a plutonium implosion device was tested at a site located 210 miles south of Los Alamos, New Mexico, on the plains of the Alamogordo Bombing Range, known as the Jornada del Muerto. The code name for the test was "Trinity."
