Warhead & Weapons Development

Lawrence Livermore National Laboratory recently conducted an experiment on weapons-grade plutonium to assess how resilient a nuclear weapon will prove when it comes up against an adversary’s missile defenses.  The experiment was conducted at the lab’s National Ignition Facility (NIF), where fusion ignition, or the output of more energy than was input, was first achieved […]
