Fission bomb
From the Resistance Wiki
A fission bomb is a standard nuclear bomb developed in the 1940's by the United States Army. President Noah Grace permits the first detonation test of a fission bomb in Alaska in 1944. In his speech confirming the bomb, Grace said: "Let it be known that American Isolationism is not cowardice, but restraint." However, America has insufficient quantities of enriched uranium to create a more effective nuclear bomb with large energy yields in mass productions. This insight had redirected the military's investment to development and research of conventional weapons and other military fields instead. It is not until after the success of Operation Allied Shield that SRPA has gained access to recovered data from the nuclear reactor in Axbridge, England which provided the nuclear research team in SRPA NT the need to create a powerful, six kiloton fission bomb.[1]
SRPA NT, under the director of Robert Oppenheimer, then built a strong yielding fission bomb code-named "Nellie", to be used in Operation Black Eden as a last resort to the destruction of the Chimeran fleet in the Yucatan peninsula, which the bomb was set to explode in the center of the fleet at the radius range of 500 feet away. Nathan Hale, Joseph Capelli, Richard Blake and other remaining Black Ops, including X-Ray Squad, head into the Chimeran flagship hovering above the Chicxulub Crater, Mexico to set and detonate the bomb. The entire Chimeran Fleet was completely destroyed in the ensuing explosion, leaving Nathan and Capelli the only survivors.
