Centauri Republic Altarian Class Destroyer

A deadly craft with a well earned reputation for its considerable lethality, the Altarian is an older design dedicated to the matter cannon. The Centauri military sciences officially stopped working on matter-related weaponry decades ago, but the ones still in service on the Altarian still function quite efficiently and are constantly repaired if need be. The Altarian lacks any serious long-ranged weaponry but is more than capable of holding its own once the battle is thoroughly joined. Its matter cannon are used for scouring large sections of hull off the enemy, making it possible for the weaker twin arrays to riddle it with holes and finish it off.

The Altarian has been around long enough that a few houses have made adjustments to them enough to create a handful of common variants. As a planetary bombardment vessel, there are few ships the size of the Elutarian in the Centauri fleet that serve so well, but in frontline battles it is often relegated as a support ship only – as it lacks flexibility. Designed by House Jaddo at the height of their power to demonstrate prestige within the Centaurum, the Magnus destroyer over the original Altarian is a subject of much debate among Centauri nobles, as it ties a great deal of resources into a ship that has never been considered a bastion of survivability. These variants are commonly seen from system to system, but the Altarian remains a steadfast favorite – even in light of its lack of superior range.
