Only days after the bombing of Hiroshima, the second operational nuclear weapon was readied by the U.S. Called "Fat Man", the unit is seen being placed on a trailer cradle in August of 1945. When the Japanese still refused to surrender after Hiroshima, U.S. President Truman issued a statement saying in part "If they do not now accept our terms, they may expect a rain of ruin from the air, the like of which has never been seen on this earth."
