From Lexicanum

The Apocalypse Class Battleship is a lance attack craft. It has no other primary armament than its lances and a mighty Nova Cannon. However, despite its seemingly limited armament it is able to reduce enemy ships, from escorts to large capital ships, into blazing hulks within a frighteningly short period of time.¹

The Apocalypse has a small weapons battery on its dorsal section, and banks of lances down the port and starboard hull. Normally the weapons batteries would be used to collapse the shields of an enemy ship, before the lances rip into the ship directly. Also, it is the only battleship armed with a Nova Cannon. This extremely long range weapon is able to obliterate whole squadrons of escorts in a single shot. The Apocalypse uses the Nova Cannon when closing in on the enemy.¹

Notable Apocalypse Class ships include

• Godefroy Magnificat
• His Will: seen during the Third War for Armageddon.¹
• Triumph: seen during the Third War for Armageddon.¹
