The Mega-class Star Dreadnought, also known as the Mega-class Star Destroyer and the Mega Star Destroyer, was a class of Star Dreadnought utilized by the First Order during their conflict with the Resistance.
The sole Mega-class Star Dreadnought in the First Order Navy was the Supremacy, the flagship of Supreme Leader Snoke as well as the de facto capital of the First Order. The Supremacy was destroyed during an attack on the Resistance fleet when Vice Admiral Amilyn Holdo rammed it at lightspeed with the heavy cruiser Raddus, slicing the Dreadnought in two and also destroying a number of its escort Resurgent-class Star Destroyers.
