OAS-class supercarrier

The OAS-class supercarrier is a heavy capital warship classification used by the Covenant.
== Overview ==
=== Superstructure and hull ===
At a length of 16,041 meters (52,627.95 feet) the OAS-class supercarrier is the largest warship in service with the Covenant fleet, being three times the length of the much more common CAS-class assault carrier. Like all Covenant capital ships the OAS is armored with a lightweight, yet incredibly resilient, diamondoid and metal-matrix composite, covered by a layer of nanolaminate plating.
=== Power generation and propulsion ===
Like all Covenant capital ships the OAS-class is powered by pinch-fusion reactors with repulsor engines for sublight propulsion and a slipspace borer for superluminal travel.
=== Armament and defenses ===
The OAS-class is heavily armed and extremely well shielded, carrying a compliment of weapons sufficient to outright annihilate entire battle groups of smaller ships. Little-to-no concrete information exists regarding the exact number of weapons these vessels possess, with estimations ranging from hundreds to thousands. What is completely clear, however, is that the supercarrier remains the most deadly vessel in the Covenant fleet, as well as one of its most valuable assets, a fact further reinforced by both the rarity of survivors in the wake of supercarrier encounters, and the rarity of the ships themselves among Covenant fleets.
