The mobile artillery served as a weapons platform utilizing repulsorlift technology, and was employed by the forces of the Galactic Empire.
This mobile artillery platform was of a smaller scale, and its projectile cannon was most effective when used against infantry forces, struggling to inflict substantial damage on heavily armored vehicles. Functionally, it mirrored the purpose of the AT-AA, engaging ground-based enemies while the walker units engaged aerial threats.
Despite its vulnerability, the mobile artillery possessed considerable speed and could rapidly bring its primary weapon into action. This deployment process involved extending forward and sideways stabilizing supports, lowering the chassis to the ground, and then elevating the main turret.
These artillery platforms were transported to combat zones within Sentinel-class landing craft. They frequently operated alongside larger artillery systems, such as the heavy artillery repulsorcraft.
A different variant of the heavy artillery featured a heavily armored, slow repulsor platform equipped with a pair of large cannons.
