- The gun-type and implosion-type designs were code-named "Thin Man" and "Fat Man" respectively. These code names were created by Robert Serber, a former student of Oppenheimer's, who worked on the Manhattan Project.

Nov 7, 2023 · Fat Man, true to its name, was 10 feet long and weighed 10,800 pounds. Its radioactive element of choice was Plutonium-239. Initially, the bomb was meant to have a “Thin Man” type design—a gun-type design like that of Little Boy.

"Thin Man" was the code name for a proposed plutonium-fueled gun-type nuclear bomb that the United States was developing during the Manhattan Project. Its development was abandoned in 1944 after it was discovered that the spontaneous fission rate of nuclear reactor -bred plutonium was too high for use in a gun-type design due to the high ...
"Fat Man" (also known as Mark III) was the codename for the type of nuclear weapon the United States detonated over the Japanese city of Nagasaki on 9 August 1945. It was the second of the only two nuclear weapons ever used in warfare, the first being Little Boy, and its detonation marked the third nuclear explosion in history.
Oct 10, 2023 · The failed plutonium gun-type design, called Thin Man. “The most daunting technical problem facing Los Alamos,” said Laboratory historian Roger Meade, “was how to fashion the limited quantities of two very different [fissile] materials, uranium-235 and plutonium-239, into combat weapons.”
The enriched-uranium gun would not have to be as high pressure as the plutonium gun, so they could shorten it. So what was once the Thin Man became the Little Boy. The implosion bomb was bulbous and round. Serber claims calling it the Fat Man was his idea, and based on the Sydney Greenstreet character in The Maltese Falcon. (Serber, it seems ...
Feb 22, 2023 · Why did the United States choose to use an untested uranium-fueled (Little Boy) bomb at Hiroshima instead of a plutonium-fueled (Fat Man) bomb, which had been successfully tested at Trinity? Surely the components for additional plutonium bombs were available, as evidenced by events at Nagasaki a few days later.
Fat Man, atomic bomb dropped on the city of Nagasaki, Japan, on August 9, 1945. Its use was the second and last time that nuclear weapons were employed in war. Fat Man was a plutonium implosion-type bomb.
