The Elysium-class heavy guided-missile cruiser, also known as the Elysium-class command cruiser, was a class of heavy cruiser that was overshadowed by its close cousin the Marathon-class. Introduced in 2511 it was marketed as a superior replacement for the ineffective Halcyon-class, it was the first of the “modern” generation of warships with top-of-the-line weapons and armor. The last operational Elysium-class cruiser, the UNSC Lepanto, was destroyed during the Fall of Reach.
