HVs-2 hypervelocity gun
The HVs-2 hypervelocity gun is a fixed planetary defense weapon used against orbiting space-crafts such as capital ships by the Galactic Empire during the Galactic Civil War.[1] In Star Wars: Empire at War, it is a "superweapon" capable of penetrating shields to destroy multiple hardpoints on larger ships, and can destroy multiple corvettes in a single shot if they are stationary.
In Galactic Conquest, Hypervelocity guns are a planetary upgrade (one per planet), available at Tech level 4. In skirmishes, it is purchased as an upgrade from the player's Imperial space station, and then accessed from the on-screen button interface.
