Re: Project Orion
"What is the elegant solution for burning out all the electronics in the hemisphere that Orion launches from?"
Not using megaton-class devices is a good starting point (Starfish Prime was 1.45MT, the Soviet equivalent was larger and fried most of central asia's electrical grid) ). Orion was built around 50kT devices - one of the reasons large parts of it are still classified - the bombs are SMALL and would be of use to terrorists because they're highly portable
