Liberty-class battlecruiser (EXverse)

The first battlecruiser to be commissioned by the UNSC Navy, the Liberty-class battlecruiser is a powerful medium-size capital ships currently serving in the UNSC reserve fleet.
Conceived during the days of the Harvest Campaign as a strong stopgap to counter heavy Covenant ships with, Liberties were designed and introduced in a very short time due to the unrivaled Covenant firepower and protection. Although having one of the most powerful MAC guns of the war, aside from Super MACs, Liberties were nothing more than a subclass of the : as such they retained much of the main class' characteristics, such as a thin armor.
Commissioned by 2527, they could take down a in two shots and with shields up, or even tear down with four/five slugs; its firepower later inspired partially the Epoch's battleship variant, demonstrating that Covenant were powerful, but not invincible. However Liberties proved to be very useful only in wolfpack tactics due to superior Covenant technology, and thanks to this they were updated throughout the war, giving life to three distinct blocks.
Only four Liberties survived the war, and they were put in the reserve fleet.
