The Main Engine is a primary mode of propulsion for giant Warships. Though the Warship can remain aloft with the main engine destroyed, achieving velocity of any decent will be impossible. The Main Engine's not without defenses though. If it's under attack, the engine will unleash fast energy blasts directly behind the Warship. It is called "Heavy Raid" in Final 2.
