Operation Emperor's Spear was a battle tactic used by Wedge Antilles and the Insiders at the Battle of Borleias during the Yuuzhan Vong War. Because the Executor-class Star Dreadnought Lusankya had already taken severe damage in the defense of Borleias, it was decided that she would be used in a final suicide mission against the worldship in command of all Yuuzhan Vong forces in the Pyria system. The plan involved installing a giant reinforced lance into the center of Lusankya, filling it with explosives and ramming the ship into the Domain Hul worldship.
