Unlike the Shadowsword's Volcano Cannon, the Stormblade's Plasma Blastgun is a less voracious consumer of energy and can be fired either at full power or in short bursts, granting the Stormblade a much greater tactical flexibility that the Shadowsword at the cost of some firepower. On the battlefield, the Stormblade's primary function is to blast Titans and enemy super heavy armour into oblivion, although unlike the Shadowsword, it is more of a medium-range heavy support vehicle than a pure Titan-killer. Stormblades are built on Forge Worlds that lack the ability to build true Shadowsword tanks, and thus have to compensate by using different weaponry and other less advanced technologies than the original. It is armed with a Plasma Blastgun instead of a Volcano Cannon, but it is still able to perform the role of Titan-hunter on the battlefield.

The Stormblade super-heavy tank is a variant of the Astra Militarum's Shadowsword Titan-killer tank.
