Technologies to 'refine U235' did not exist. Sufficiently fast
switches to trigger the explosives did not exist. Neutron tampers did
not exist. The required explosive (probably) did not exist.


Actually, for the gun bomb, the only thing needed was technologies to
refine the Oralloy. The propellant was ordinary cordite ignited with
a stock igniter.

The implosion weapon was a whole different kettle of fish...
