Where exactly were nuclear bombs manufactured on a large scale?
they are consructed in secret military sites .but this is just a wild guess
Several sites existed, especially for components. The main assembly site for most of the cold war was PANTEX near Amarillo, TX. Early sites included: Los Alamos Kirkland AFB in Albuquerque, NM Most of the large Pacific test shots were assembled on Perry Island at Eniwetok atoll and then sailed on landing craft transports to the detonation location.
Conventional bombs use conventional explosives or incendiary materials, e.g. TNT, RDX, C-4, Semtex, Magnesium, Napalm. They cause localised damage with fairly consistent and predictable effects. They are usually cheap and leave little ongoing damage once detonated. Nuclear bombs use the power of either nuclear fission or nuclear fusion or both. The result is enormous amounts of energy released in microseconds, with wholesale destruction over a large area, and leave radioactive fallout all around.
These are the only two nuclear bombs ever used in war, and with good reason. The devastation from the bombs was unfathomable, and as the extent of the destruction became public knowledge, the bombs themselves became a symbol of the atrocity of war. Sadly, the threat of nuclear weapons seems to have faded from the public consciousness, even as the fear of terrorist attacks looms large. With all the talk of "dirty bombs" and "suitcase…
