The Trinity bomb contained plutonium.
The first bomb exploded, the Trinity test bomb, used plutonium. The first bomb deployed, dropped on Hiroshima, used uranium 235. The second bomb deployed, dropped on Nagasaki, used plutonium 239.
Many elements were used in the first atomic bombs in the nonnuclear parts. As I cannot possibly list them all (the most common elements were the carbon, nitrogen, and oxygen used in the chemical explosives) I will only address the elements used as the nuclear fuel that powered the atomic explosion.Gadget, plutonium-239 (Trinity site test on July 16, 1945)Little Boy, uranium-235 (Hiroshima bombing on August 6, 1945)Fatman, plutonium-239 (Nagasaki bombing on August 8, 1945)Gilda, plutonium-239 (Operation Crossroads Able test on June 30, 1946)Helen of Bikini, plutonium-239 (Operation Crossroads Baker test on July 24, 1946)all 3 Operation Sandstone tests in 1948 used plutonium-239all 5 Operation Ranger tests in 1951 used plutonium-239the first 2 Operation Greenhouse tests in 1951 used plutonium-239the third Operation Greenhouse test in 1951 used plutonium-239 and deuterium (boosted fission)the fourth Operation Greenhouse test in 1951 used plutonium-239 and tritium (boosted fission)all 7 Operation Buster-Jangle tests in 1951 used plutonium-239the 8 Operation Tumbler-Snapper tests in 1952 used various combinations of uranium-235, plutonium-239, and deuterium in different teststhe first Operation Ivy test in 1952 used plutonium-239, deuterium, and tritium (it was the first hydrogen bomb)the second Operation Ivy test in 1953 used uranium-235 (at about 500 kiloton yield it was the largest pure fission explosion ever)the 11 Operation Upshot-Knothole tests in 1953 used various combinations of uranium-235, plutonium-239, lithium, and deuterium in different tests (several were "hydrogen bomb mockups" without the fusion fuel to test the principle of radiation implosion)the 6 Operation Castle tests in 1954 used various combinations of lithium, deuterium, and plutonium-239 (these included the first tests of practical designs for deliverable hydrogen bombs)etc.
The fissile fuel in the first 3 bombs was:Plutonium, Trinity test, July 16, 1945Uranium, Hiroshima attack, August 6, 1945Plutonium, Nagasaki attack, August 9, 1945Trinity test Gadget: Plutonium. First atomic bomb detonation.Hiroshima Little Boy: 80% enriched Uranium. First atomic bomb used in combat.Take your pick.
It was designed and the kits of parts were crated at Los Alamos, NM. The Trinity test device was assembled at the Trinity site. The two bombs dropped on Japan were assembled on the island of Tinian.
Wedges of the metal Plutonium were assembled into a ball shape, and surrounded by explosives. When the explosives detonated, they crushed the ball into a smaller, denser ball, triggering a nuclear fission reaction. This changes Plutonium into other materials, and releases huge amounts of energy very quickly. However, the first atomic bomb used in war was a different design. A "bullet" of Uranium 235 metal was fired down a gun barrel into a larger mass of Uranium 235. When the two pieces of Uranium were rapidly brought together, the nuclear fission reaction began.
The Trinity Test was the first test of a nuclear device. The bomb detonated at the trinity test was an implosion-type plutonium bomb nicknamed 'the gadget' the bomb was the same type of bomb that was dropped on Nagasaki Japan.
The atomic bomb tested at the Trinity test site in New Mexico during World War II was a plutonium-based implosion-type bomb known as "Gadget." This test marked the first detonation of a nuclear weapon.
Plutonium was used in the Trinity test, Uranium in the first combat weapon.
The first bomb that was used on people (Little Boy) used Highly Enriched Uranium as its fissile material. The first tested bomb at the Trinity Test used Plutonium as its fissile material.
The Trinity test shot was done to verify the Plutonium implosion mechanism. The Hiroshima bombing was the beginning of nuclear war with Japan to force them to surrender.
In the test bomb, the material was plutonium. Plutonium was also used in one of the bombs dropped on Japan, Fat Man. Little Boy, the bomb dropped on Nagasaki, was made of uranium.
The first bomb exploded, the Trinity test bomb, used plutonium. The first bomb deployed, dropped on Hiroshima, used uranium 235. The second bomb deployed, dropped on Nagasaki, used plutonium 239.
Trinity was the first test of technology for a nuclear weapon. It was conducted by the United States on July 16, 1945, at a location 35 miles (56 km) southeast of Socorro, New Mexico, on what is now White Sands Missile Range, headquartered near Alamogordo. Trinity was a test of an implosion-design plutonium bomb. The Fat Man bomb, using the same conceptual design, was dropped on Nagasaki, Japan, on August 9th. The Trinity detonation was equivalent to the explosion of around 20 kilotons of TNT and is usually considered the beginning of the Atomic Age.
Plutonium was used in the first A-bomb, the Trinity test of July 16, 1945. Uranium, more specifically ore highly-enriched in U-235, was used to create the "Little Boy" bomb dropped on Hiroshima (August 6, 1945). The "Fat Man" dropped on Nagasaki (August 9, 1945) was another plutonium "implosion" bomb with about 40% higher yield than Little Boy. Plutonium became the typical fissile element in fission-fusion bombs.
Apparently it was plutonium which I think is element 295.Plutonium is element 94.Plutonium was used in the Gadget at Trinity.Uranium was used in the first bomb dropped on Japan the Little Boy at Hiroshima.Plutonium was used in the second bomb dropped on Japan the Fatman at Nagasaki.
It was called the Trinity test. It was tested in Trinity, New Mexico. It was not too far from Alamogordo New Mexico.
Trinity is usually estimated at 20 kilotons.
