Because of its complicated firing mechanism, and the need for previously untested synchronization of explosives and precision design, it was felt that a full test of the concept was needed before the scientists and weight reduction military representatives could be confident it would perform correctly under combat conditions. On July 16, 1945, a device utilizing a similar mechanism (called the "gadget" for security reasons) detonated in a test explosion at a remote site in New weight reduction Mexico, known as the "Trinity" test. In the end, it gave weight reduction somewhere around 20 kt (80 TJ), 2 to 4 times the expected yield. The Soviet Union's first nuclear weapon detonated at Operation First Lightning (known as "Joe 1" in the West) was more or less a purposeful copy of the "Fat Man" device, on which they had obtained detailed information from the spy Klaus Fuchs. |

| The spontaneous fission rate of Pu-240 is 415,000 fissions/(s·kg), and the amount was 0.9% of 6.2 kg, is 56 g. Thus there were 23,000 spontaneous fissions per second. This means that the last few centimeters jamesmundie would have to be travelled in preferably much less than 40 microseconds. It is theoretically possible jamesmundie to build a plutonium gun-type device, but it would need to be 19 feet long in order to allow the sub-critical masses to be fused into a critical mass before a fizzle occurs. The mass of a plutonium gun-type device would have been beyond the payload of the jamesmundie B-29. After this problem was realized in 1943, work began in earnest on the implosion bomb, the "Fat Man". The gun-type method could still be used for highly-enriched uranium, though, and was employed in the "Little Boy" weapon which was used against Hiroshima, Japan. For a variety of reasons, the implosion method is both more efficient than the gun-type method, and also far safer, as a perfect synchronization of the explosion lenses is required for the core to properly detonate, greatly reducing the chances of an accidental nuclear detonation. |
