Summary

Description Casings for the "Thin Man" plutonium gun design weapons being developed during the Manhattan Project as part of Project Alberta at Wendover Field, Utah (additional "Fat Man" test casings can be seen in the background as well). The plutonium gun design was eventually abandoned as infeasible, as the spontaneous fission rate of reactor-bred plutonium was much higher than expected.
