Do current nuclear weapons use complicated interstage devices, like 'radiation bottles' and burn through walls, or were those just for specials tests like Ripple?
I read about those here. Maybe they're deservedly classified and speculative, but are 'pulse shaping' devices not actually necessary for the miniaturized, smaller TN weapons actually deployed, and were maybe just used for large tests to prove a principle? Or they could be part of current TN technology efficiency?
