The B77 was a nuclear bomb designed in 1974 to match the delivery capabilities of the B-1A bomber. This included the ability to be dropped from supersonic speeds at altitudes of 60,000 feet (18,000 m), or in a laydown delivery at high subsonic speeds at …

The B57 nuclear bomb was a tactical nuclear weapon developed by the United States during the Cold War. Development began at the Los Alamos National Laboratory in 1960 to meet a requirement for a multi-purpose weapon, suitable for use as a nuclear depth charge or a nuclear bomb against ground targets. [ 1 ]

The B77 was designed with an active altitude control and lifting parachute system for supersonic low-altitude delivery from the B-1A bomber. Likely B77 nuclear component test firings were attributed to the Operation Anvil series in 1975 and 1976, …

2011年7月24日 · B77 Strategic Bomb. The B83 is derived from the earlier B77, which was terminated due to cost, complexity, and the excessive weight of the bomb delivery system.

The B83's roots are in the B77, a very expensive strategic bomb under development in the 1970s.

1945年8月9日，即 廣島市 首枚原子彈爆炸後3天，由 查尔斯·斯威尼 （英语：Charles Sweeney） 駕駛的 B-29超級空中堡壘轟炸機 「博克斯卡」（Bockscar）在長崎上空31,000英呎（9,000米）投下。 在 日本標準時間 11時02分，在1,800呎（550米）高度爆炸 [1]。 「胖子」是至今為止歷史上第二次亦是最後一次投入实战的 核武器。 它長10英呎八吋（3.25 米），直徑五英呎（1.52米），重10,000磅（4,545 公斤）。 釋放的能量約相等於2.1萬 噸 的 TNT 烈性炸藥，即大概 …

B77 nuclear bomb. The B77 was designed to match the delivery capabilities of the B-1A bomber. It was to replace the Mk 28 and Mk 43 bombs in the strategic bombardment role. The specifications for the B77 required Full Fusing Options (FUFO) and the ability for a low altitude, transonic laydown delivery, as well as a free fall from supersonic ...

The B77 was a nuclear bomb designed to match the delivery capabilities of the B-1A bomber. This included the ability to be dropped from supersonic speeds at altitudes of 60,000 feet, or in a laydown delivery at high subsonic speeds at altitudes as low as 100 feet.

原子弹，又称 裂变弹[1]，是利用 铀 、 钚 等可裂变物质的 核裂变 链式反应释放巨大能量而制成的 爆炸裝置，為 核子武器 的其中一種。 原子弹主要由核装药、反射层、引信等部件组成，分为枪式原子弹和收聚式原子弹两种类型，其破坏力主要来源于强烈的光辐射、冲击波、核辐射等效应。 原子弹的研发始于20世纪30年代后期，于二战期间由 美国 通过 曼哈顿工程 率先研制成功，并于1945年8月在 广岛 和 长崎 投下两枚原子弹。 随后 苏联 等国相继试爆自制的原子弹。 时至今 …

Kel F-800 fluorocarbon polymer has been selected as the binder for the TATB explosive in the B77 bomb. Kel F-800 is a 3M copolymer derived from the monomers chlorotrifluorethylene (CTFE) and vinylidine fluoride (VF/sub 2/).
