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. the allies issued orders for atomic bombs to be used on four japanese cities on july 25. on august 6, one of the modified b-29s dropped a uranium gun-type bomb ("little boy") on hiroshima. another b-29 dropped a plutonium implosion bomb ("fat man") on nagasaki three days later. the bombs immediately devastated their targets. over the next two to four months, the acute effects of the atomic bombings killed between 90,000 and 146,000 people in hiroshima and 39,000 and 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 for months afterward from the effects of burns, radiation sickness, and other injuries, compounded by illness and malnutrition. in both cities, most of the dead were civilians, although hiroshima had a sizable military garrison.
