Mike,

Thanks for this picture. I thought the Archies had to be behind the physics package because of it's size and this picture confirmed this.

AD3F posted a link that shows the Little Boy configuration, and you can see the four Archies in this declassified photo of the tail end of the Fat Man (Mark III) weapon. The "fat" nuclear part of the weapon is immediately behind this "C" plate. Each Archie is a complete set with its own antenna, with some minor mods inside. For example, the "Maintenance and Instruction Manual for Mark III Atomic Bomb Fuse" consists of 15! volumes, but in this particular volume the description mentions that the barometric fuse in the nose prevents one transmitting tube and one receiving tube in each Archie from operating, to prevent jamming and detection until approximately 5,000 feet is reached in the drop.
