The first fission bomb, codenamed " The Gadget ", was detonated during the Trinity Test in the desert of New Mexico on July 16, 1945.

The energy dynamics of pure fission bombs always remain at about 6 % yield of the total in radiation, as a prompt result of fission.
43.
Even if the Soviets built a fusion weapon, the scientists said, the 169 fission bombs the United States had were more than enough of a deterrent.
44.
Considering the idea of the fission bomb theoretically settled at least until more experimental data was available the Berkeley conference then turned in a different direction.
45.
A number of the different fission bomb assembly methods explored during the summer 1942 conference, later reproduced as drawings in " The Los Alamos Primer ".
46.
The primary stage was a TX-5 boosted fission bomb in a separate space atop the assembly ( so it would not freeze, rendering it inoperable ).
47.
At the other extreme, he designed Super Oralloy, which was at the time, McPhee wrote, " the largest-yield pure-fission bomb ever constructed in the world ."
48.
There was reasonable confidence in knowing the size of the Soviet fission bomb inventory, but much less confidence about estimates of the biological and chemical warfare capabilities.
49.
Research has been done into the possibility of pure fusion bombs : nuclear weapons that consist of fusion reactions without requiring a fission bomb to initiate them.
50.
The main focus of fission-related problems is interaction of atomic nuclei with neutrons : a process that occurs in a fission bomb and a nuclear fission reactor.
