N2 weapon

An N2 weapon is a type of exotic weapon of mass destruction capable of destroying entire planets, developed by the Imperial Navy for a theoretical full-scale war with more powerful entities outside of Imperial Space. At the most basic level, a miniature neutron star is artificially formed under strong pressure from powerful electromagnetic fields. Upon deployment, the electromagnetic fields are deactivated and the matter within would immediately expand, setting off a massive nuclear explosion that can end all life on a planet.
