Atomic bombings of Hiroshima and Nagasaki
By August 1945, the Allies' Manhattan Project had produced two types of atomic bombs, and the 509th Composite Group of the United States Army Air Forces (USAAF) was equipped with the specialized Silverplate version of the Boeing B-29 Superfortress that could deliver them from Tinian in the Mariana Islands. Orders for atomic bombs to be used on four Japanese cities were issued on July 25. On August 6, one of the modified B-29s dropped a uranium gun-type bomb codenamed "Little Boy" on Hiroshima. Three days later, on August 9, a plutonium implosion-type bomb codenamed "Fat Man" was dropped by another B-29 on Nagasaki. The bombs immediately devastated their targets. Over the next two to four months, the acute effects of the atomic bombings killed 90,000–146,000 people in Hiroshima and 39,000–80,000 people in Nagasaki; roughly half of the deaths in each city occurred on the first day. Large numbers of people continued to die from the effects of burns, radiation sickness, and other injuries, compounded by illness and malnutrition, for many months afterward. In both cities, most of the dead were civilians, although Hiroshima had a sizable military garrison.

The atomic bomb was dropped on Nagasaki, Japan on August 9, 1945, but while the Allies awaited Japan's response to the demand to surrender, the war continued. On August 13, 1945, 1st Lt. Perdomo shot down four Nakajima Ki-43 "Oscar" fighters and one Yokosuka K5Y "Willow" Type 93 biplane trainer. This action took place near Keijo/Seoul, Korea when 38 Thunderbolts of the 507th Fighter Wing encountered approximately 50 enemy aircraft. This action was Lt. Perdomo's tenth and final combat mission, and the five confirmed victories made him an "Ace in a Day" and earned him the distinction of being the last "Ace" of World War II. He was awarded the Distinguished Service Cross for extraordinary heroism in action and the Air Medal with one oak leaf cluster.
