The Mark 24 nuclear bomb was an American thermonuclear bomb design, based on the third American thermonuclear bomb test, Castle Yankee. The Mark 24 bomb was tied as the largest weight and size nuclear bomb ever deployed by the United States, with the same size and weight as the Mark 17 nuclear bomb which used a very similar design concept but unenriched Lithium. The Castle Yankee thermonuclear test was the first bomb to use enriched Lithium-6 isotope, up to perhaps 40% enrichment. The device tested was called the Runt II design; it was reportedly very similar to the Runt design tested in Castle Romeo, other than the enrichment level. Castle Yankee had a demonstrated yield of 13.5 megatons. The yield for the weaponized Mark 24 was predicted to be 10–15 megatons. The EC24 bomb was a limited production run of the Castle Yankee test device, with 10 produced and stockpiled through 1954. The EC24 was and weighed . The EC24 was a purely free-fall bomb design. The production model Mark 24 nuclear bomb was long, with a weight between . It was in service between 1954 and 1956, with a total of 105 units produced. The Mark 24 included a parachute to slow its descent. ==See also== * List of nuclear weapons * Nuclear weapon design * Teller-Ulam design * Mark 17 nuclear bomb * Castle Yankee 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mark 24 nuclear bomb」の詳細全文を読む スポンサード リンク
