Fogbank is a code name given to a material used in the W76, W78 and W88 nuclear warheads that are part of the United States nuclear arsenal. Fogbank's precise nature is classified; in the words of former Oak Ridge general manager , "The material is classified. Its composition is classified. Its use in the weapon is classified, and the process itself is classified." Department of Energy Nuclear Explosive Safety documents simply describe it as a material "used in nuclear weapons and nuclear explosives" along with lithium hydride (LiH) and lithium deuteride (LiD), beryllium (Be), uranium hydride (UH3), and plutonium hydride.

  • Fogbank is a code name given to a material used in the W76, W78 and W88 nuclear warheads that are part of the United States nuclear arsenal.

Department of Energy Nuclear Explosive Safety documents simply describe it as a material "used in nuclear weapons and nuclear explosives" along with lithium hydride (LiH) and lithium deuteride (LiD), beryllium (Be), uranium hydride (UH3), and plutonium hydride. However National Nuclear Security Administration (NNSA) Administrator disclosed the role of Fogbank in the weapon: "There's another material in the—it's called interstage material, also known as Fogbank", and arms experts believe that Fogbank is an aerogel material which acts as an interstage material in a nuclear warhead; i.e., a material designed to become a superheated plasma following the detonation of the weapon's fission stage, the plasma then triggering the fusion-stage detonation.

Sin embargo, Tom D'Agostino, Director de la Administración Nacional de Seguridad Nuclear (NNSA por sus siglas en inglés), reveló la función de FOGBANK en el arma: " Hay otro material en él— se le llama material intermedio, también también conocido como fog bank"; los expertos en armas creen que el FOGBANK es un material compuesto por aerogel el cuál actúa como un material intermedio en una ojiva nuclear; esto es, un material diseñado para devenir en plasma sobrecalentado al que le sigue la detonación en la etapa de fisión del arma, el plasma entonces desencadena la etapa de fusión-detonación.​ (es)
