The "Trinity" device was similar to the "Fat Man" bomb. 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 military representatives could be confident it would prarie home companion perform correctly under combat conditions.

The spontaneous fission rate of james porter 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 would have to be travelled in preferably much less than 40 microseconds. It is theoretically possible to build a plutonium gun-type device, but it would need to be 19 feet long in order james porter to allow the sub-critical masses to be fused into a critical mass before james porter a fizzle occurs. The mass of a plutonium gun-type device would have been beyond the payload of the 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.
