The Invincible-class Dreadnaught Heavy Cruiser, sometimes referred to as the Invincible-class Heavy Cruiser or Invincible-class Dreadnaught, was a type of warship that served for many centuries in naval forces around the galaxy.


The Invincible-class was a cylindrical-shaped, 2,011 meter long warship. The variant in use with the Corporate Sector Authority fleet was armed with six concussion missile tubes, twelve turbolaser cannons, thirty quad laser cannons and six tractor beam projectors.


Designed after the massive battlecruisers that served in the navies of Xim the Despot and the colossal battle cruisers of the Alsakan, the Invincible-class dreadnaught was constructed by Rendili StarDrive and Vaufthau Shipyards, Ltd.,[1] c. 3017 BBY,[2] during the Seventeenth Alsakan Conflict between Coruscant and Alsakan. They were among the largest Republic capital ships of the era.[1]

Soon after their development, changes in weapons technology rendered large capital ships like the Invincible-class extremely vulnerable to small, fast attack ships. For many centuries the balance of military power would rest with smaller warships only a few hundred meters in length. Nevertheless, this class saw some use with the forces of the Galactic Republic, and a number of them were later acquired from Imperial surplus by the Corporate Sector Authority and fielded as picket ships. Advisors hired from system defense navies that still used this and other outdated ships were used to train crews to operate the Invincible-class as well as do minor systems upgrades to the vessels.[1]

Despite their large size and crew complement, they were generally limited to combating pirates and smugglers, but they were cheap to acquire and simple to operate, and they combined an atmospheric maneuvering capability with the ability to deploy a relatively large force of ground troops.
