Poseidon-class heavy cruiser

The Poseidon-class heavy cruiser (Hull Classification Symbol: CA) is a warship in service with the UNSC Navy during the 27th century.
== Overview ==
The Poseidon-class heavy cruiser is 1,500 meters in length. It is a well-rounded capital ship, striking a balance between mobility, armor, firepower, crew requirements, and ease of manufacturing. Much of the resiliency these cruisers' display comes from the installation of thick plates of ablative armor. When the cruisers come under fire from plasma weaponry, the plating boils off, sparing the internal structure, weapons, and crew from critical damage until it is eroded away. The Poseiden-class is built with distinctive armor cowlings protecting the cruiser's powerful impulse drives, inspired from costly lessons learned by the UNSC Navy during the Insurrection.
