Iridium arrays are very common, due to their effectiveness when mixed along with Kinetic driver turrets and necessary for projectile turrets to be effective. If placed on the Bridge, they're also commonly mixed with phased munitions. However, despite their increased speed, they still have a tendency to miss decoys, as they don't have a perfect accuracy. Despite their efficiency while mixed with Kinetic driver turrets, they tend to work best while mixed with Arrestor beam turrets - such a combination, the Kinetic driver turret is unlikely to ever miss their target,
Gladius driver turrets, which already have 2000 m/s base speed, are also equipped with these, in order to increase their already significant accuracy.
