The Orbital Bombardment Particle Cannon represented a specific configuration of particle cannon alongside mass-driver cannon technology. It was rumored to draw power from kyber crystals, and the Rebel Alliance reportedly classified it as a superweapon. It was possible to equip Onager-class Star Destroyers with either two Superheavy Composite Beam Turbolasers or two Orbital Bombardment Particle Cannons.
