''For the Sinclair Research Ltd. SC/MP based computer system see MK14.'' For the torpedo see Mark 14 torpedo. The Mark 14 nuclear bomb was a 1950s Strategic thermonuclear weapon, the first solid-fuel staged hydrogen bomb. It was an experimental design, and only five units were produced in early 1954. It was tested in April 1954 during the Castle Union nuclear test and had a yield of 6.9 Mt. The bomb is often listed as the TX-14 (for "experimental") or EC-14 (for "Emergency Capability"). It has also been referred to as the "Alarm Clock" device though it has nothing to do with the design by the same name proposed earlier by Edward Teller and known as the Sloika in the Soviet Union. The fusion fuel used by the bomb was 95% enriched Lithium isotope 6 lithium deuteride, which at the time was a scarce resource and chiefly responsible for its limited deployment. The Castle Bravo test showed that unenriched Lithium isotope 7 functioned as well for nuclear fusion reactions as isotope 6. The Mk-14 bomb had a diameter of and a length of . They weighed between , and used a parachute.〔(List of All U.S. Nuclear Weapons ) at NuclearWeaponArchive.org〕 The version tested at Castle Union used a RACER IV primary, and had 5 Mt of its total yield due to fission, making it a very "dirty" weapon.〔 *(Operation Castle ) at NuclearWeaponArchive.org〕 By 1956, the components of all of the five produced Mk-14 bombs had been recycled into Mark 17s. ==See also== * List of nuclear weapons 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 14 nuclear bomb」の詳細全文を読む スポンサード リンク
