More appropriately, the [[Little Boy]] article, and its current primary source (John Coster-Mullen's book). The general gun-type weapon article only contains generalities. The Little Boy article contains a precise but not dimensioned diagram of the weapon, and detailed dimensions and masses for the critical assembly (uranium parts), and weights for the subassemblies of the tamper/reflector and the steel casing components. John's book from which the diagram and details were derived has detailed dimensions (enough to draw a blueprint and manufacture a functional replica) on all the functional parts. John's book was derived from firsthand measurements of Little Boy units in museums, plus most of the design and development and assembly records, which were declassified (and then apparently reclassified, but the copies already out aren't legally recallable so they're effectively all public now). Of course, that's a 5-metric-ton weapon, which is not militarily useful at this point. -- -george william herbert [email protected] _______________________________________________ WikiEN-l mailing list [email protected] To unsubscribe from this mailing list, visit: https://lists.wikimedia.org/mailman/listinfo/wikien-l
