'''Castle Bravo''' je [[širirano]]ime za operacijo pod katerim so ZDA prvič testirali [[vodikova bomba|termonuklearno vodikovo bombo]].Test so opravili 1.3.1954 ob [[Bikini Atollu]] na [[Maršalovih otokih]]. [[Jedrski dež]] je kot posledica testiranj (ta naj bi bila tajna)je zastrupil otočane ki so se po detonaciji vrnili na otok. Zastrupili so se tudi člani posadke japonske ribiške ladija <Lucky Dreagon No.5>, kar je sprožilo mednarodno vprašanje o varnosti izvajanja jedrskih poizkusov.
Za bombo je bilo uporabljeno [[litij-deveteijevo]] gorivo za [[nuklearno reakcijo]], kot tudi [[kriogenska]],[[devetieva]]–[[tritijeva]],tekočine ki so bile uporabljene kot gorivo za jedrsko reakcijo za poizkus ZDA.Bomba [[Ivy Mike]] ki je bila označena kot [[16 jedska bomba]]. ¸Poizkus Castle Bravo je bil prvi praktični preizkus [[vodikove bombe]] ameriške vojske
[[Sovjetska zveza]] je že prej uporabila litijev devterij v [[Sloika]] (znano kot "Alarm Clock" v ZDA) leta 1953. To ni bila prava vodikova bomba, reakcija je sprostila samo 15-20%svojega donosa, večinoma dobljene s pospešenih reakcij fuzije. njen donos je bil omejen na 400 kiloton in ni bila prava jedrska bomba.
[[Teller-Ulomva]]osnova bombi [[Ivy Mike]] je imela veliko večjo moč 10,4megaton, ki je večinoma prišla z fizijo: 77% ocelotne moči.
Castle Bravo had the greatest yield of any US nuclear test, 15 MT, though
again a substantial fraction came from fission. In the Teller-Ulam design, the fission and fusion stages were kept physically separate in a reflective cavity. The radiation from the exploding fission primary brought the fuel in the fusion secondary to critical density and pressure, setting off thermonuclear (fusion) chain-reactions, which in turn set off a tertiary fissioning of the bomb's outer casing. Consequently this type of bomb is also known as a [[Boosted_fission_weapon|"fission-fusion-fission"]] device. The Soviets, led by [[Andrei Sakharov]], independently [[Sakharov's Third Idea|developed]] and [[RDS-37|tested]] their first Teller-Ulam device in 1955.
Castle Bravo was the most powerful [[nuclear weapon|nuclear device]] ever detonated by the United States, with a yield of 15 [[megaton]]s. That yield, far exceeding the expected yield of 4 to 6 megatons, combined with other factors, led to the most significant accidental [[radioactive contamination|radiological contamination]] ever caused by the United States.
In terms of [[TNT equivalent|TNT tonnage equivalence]], Castle Bravo was about 1,200 times more powerful than each of the atomic bombs which were [[Atomic bombings of Hiroshima and Nagasaki|dropped]] on [[Hiroshima]] and [[Nagasaki, Nagasaki|Nagasaki]] during [[World War II]]. The largest nuclear explosion ever produced was a test conducted by the [[Soviet Union]] seven and a half years later, the ≈50 MT [[Tsar Bomba]]. Castle Bravo is the fifth largest nuclear explosion in history, exceeded by the Soviet tests of [[Tsar Bomba]] at 50.6 MT, [[Test 219]] (24.2 MT), and two other ~20 MT Soviet tests in 1962 at [[Novaya Zemlya]].
