BattlecruiserDefensiveMatrix SC2 Rend2

A battlecruiser using a defensive matrix

The defensive matrix is a form of terran energy shield technology.


By 2499, Confederate scientists had developed a short-lived defensive matrix that could be created by science vessels.[1] The technology gained a favorable reputation during the Brood War, where matrix technology was credited for saving many lives.[2]

By 2504, LarsCorp Technologies had developed a defensive matrix system for Minotaur-class battlecruisers.[2] Defensive matrix technology was also outfitted on the Gorgon-class battlecruiser, the Bucephalus.[3]

Harvesters are equipped with defensive matrix technology. However, they are only capabel of using the technology on themselves, and these shields only last a few seconds.[4]

Game EffectEdit


In StarCraft, the science vessel can project a defensive matrix onto other units.

The following section contains information from a previous version of StarCraft II which is no longer valid.

The nomad used to be able to create a defensive matrix (at BlizzCon 2007). The nomad could create a damage suppression field which reduces all incoming damage by 50% at the target area.[5]

One model of the battlecruiser could protect itself with a defensive matrix in earlier builds.
