In addition to their usual weapons batteries, many Ork starships are also armed with so-called 'Heavy Gunz' that are extremely short-ranged, but deal immense damage.
Ork weapons batteries (or 'Gunz') are notable for their questionable reliability, with individual weapons often failing or running out of ammunition, yet with others simultaneously being repaired (or even improved), right in the midst of an ongoing battle. While the weapons batteries of many different factions like Chaos and the T'au have a similar end effect to those employed by the Imperium, several of the intelligent starfaring races such as the Tyranids and the Necrons use weapons batteries that are significantly different in how the weapons output is produced from the norm across the human-settled galaxy. Nearly all warships are well-armed with gun ports and weapon housings for weapons batteries.
'Weapons battery' is a generic name for the Macrocannons, Plasma Batteries, Laser Cannons, Railguns, and Missile Launchers that make up the vast majority of spaceborne weapons and can be fired in a multitude of ways, from one concentrated blast to a pattern determined by the captain.
