- "I'm just not convinced you need a moon-sized reactor to power a kyber crystal cannon."
- ―Haxen Delto, to Airen Cracken in a report
The Onager-class Star Destroyer, referred to as the Siege Breaker by the Rebel Alliance, was a type of capital ship that was propelled by five engine units in the stern of the starship, three of which were larger than the remaining two. A solar ionization reactor was located in the ventral hull, characterized by its dome shape. The bridge was situated inside the elevated command tower at the center of the ship towards the rear, and the bridge itself was located on a near-trapezoidal structure on top of the command tower.
The front of the ship was defined by two prongs which defined the bow as a T-shaped bow with a long indentation in the center that cut through to almost midship where the primary armament was located. Past the ending of the indentation but before the command tower structure, were two deflector shield generators similar to those found in Imperial-class Star Destroyers. In the same fashion as ISDs, the Onager-class had a ridge that traversed the port and starboard sides of the vessel. The Onager-class had two hangar bays, one located on the rear of each of the two prongs that form the T-shape of the bow. The Onager-class was able to receive starships, such as a Lambda-class T-4a shuttle and TIE line starfighters. Members of the Rebel Alliance believed that the Galactic Empire could build thousands of Onager-class Star Destroyers for the price of a single "planet-killer."
- "Maybe I lack the Empire's taste for catastrophe?"
- ―Haxen Delto, to Airen Cracken in a report
Located in the indentation was the primary armament of the Onager-class, which were the two superheavy composite beam turbolasers considered to operate as special battery armaments. These turbolasers were speculated to be powered by kyber crystals by members of the Rebel Alliance. The Rebel Alliance believed these kyber crystals were powerful enough to shatter mountains and anything but the strongest energy shield, and the ship was considered a superweapon by them.
The foundation of the weapons were at the end of the indentation by the bridge, and each weapon had at least three rings that were separated along the length of the indentation through which the payload of the weapons passed through. When these armaments fired, the indentation and rings glowed red, and could fire almost simultaneously. These two superheavy composite beam turbolasers were considered some of the Galactic Empire's most devastating weaponry and could be used to perform ignition attacks from beyond long range, allowing it to keep the crew of the vessel safe. In concert with these two primary weapons, the Onager-class was also equipped with massive particle cannons.
The Onager-class Star Destroyer was used by the Galactic Empire as a specialized orbital bombardment platform. The Rebel Alliance believed that the Siege Breaker, if their intelligence was correct, acted in the capacity of a portable cannon. The deployment of Onager-class Star Destroyers in more sensitive Imperial operations had the characteristic of not being able to be confirmed or denied.
- "Passing on the latest from Maj. Harinar and Col. Delto. I've allowed their teams to operate independently, theorizing on the most likely configuration that a kyber superweapon would take. As you will see, they arrived at very different conclusions."
- ―Airen Cracken in a report to Mon Mothma
Sometime between the years 5 BBY and 0 BBY during the early rebellion against the Galactic Empire, after the Rebel Alliance began detecting hints of a kyber crystal-powered superweapon, Rebel Chief of Intelligence General Airen Cracken allowed Alliance Intelligence Major Capin Harinar of the Technology division and Colonel Haxen Delto of the Communications division to operate independently and theorize based on leads on the most likely configuration such a superweapon could take, and both arrived on different conclusions.
Major Harinar gave a report to General Cracken on an Imperial project named Operation: Cinder. Colonel Delto, however, reported to Cracken on what was known as a Siege Breaker. His analysis led him to believe that the Empire could build thousands of relatively smaller cannons, which the Rebel Alliance dubbed Siege Breakers, for the cost of a single "planet-killer." The document also included possible speculation on the characteristics and armament of the Siege Breaker, an illustration of a Siege Breaker, and a comparison to a Jedi lightsaber as they both could cut through almost any material while remaining stable in a satchel.
Delto used the document to pursue the principle that the Siege Breaker was more likely than the a large "planet-killing" battle station. After receiving both reports by Harinar and Delto, Cracken included them in his own report to Alliance Chancellor and Commander-in-Chief Mon Mothma. The report was later included in The Rebel Files, a central data repository that contained sensitive non-electric documents. Eventually, it was discovered that the "planet-killer" was the Death Star, a battle station that had the ability to destroy entire worlds.
Service during the rebellionEdit
It was later discovered that the information gathered by Alliance Intelligence on Operation: Cinder and the Siege Breaker was correct, including the illustration of the Siege Breaker and of the Operation: Cinder satellites. The Siege Breaker was officially designated as the Onager-class Star Destroyer and was deployed by the Imperial Navy to various operations, with the more sensitive operations not being able to be confirmed or denied. There were several examples of the Onager-class, with two being the Rakehell and the Cataclysm. The Rakehell at one point was accompanied by two Victory-class Star Destroyers while the Cataclysm was stationed near a pair of gravity wells and was receiving a Lambda-class T-4a shuttle and two TIE line starfighters.
The Onager-class Star Destroyer remained active after the decisive Battle of Endor that resulted in the destruction of the second Death Star and the death of Imperial Emperor Palpatine, and was still considered to be new and technologically advanced. Imperial forces that survived the Battle of Endor made strides to strengthen their grip on the galaxy and launch a counterstrike against the Rebel Alliance. The remains of the Empire believed that the Onager-class Star Destroyer was critical to achieving victory in the final stages of the Galactic Civil War.
- "Perhaps this is that the First Order is up to? Would represent a more containable risk."
- ―Caluan Ematt in a written annotation on The Rebel Files
In 34 ABY after the fall of the Galactic Empire, The Rebel Files were uncovered during an excavation on Durkteel and eventually reached the Resistance, a private military with roots to the Rebel Alliance and supported by some members of the New Republic. At that time, the Resistance was locked in a cold war with the First Order, the successor government of the Galactic Empire. Resistance Major Caluan Ematt reviewed the documentation related to the Onager-class Star Destroyer and left a written annotation describing that he believed that the First Order may have used technology or inspiration from the Onager-class Star Destroyer, and would represent a more containable risk. After war erupted between the First Order and the Resistance, the First Order Navy deployed the Mandator IV-class Siege Dreadnought, which functioned and was armed in a similar capacity to the Onager-class.
Behind the scenesEdit
The Onager-class Star Destroyer was first mentioned and pictured in the canon boxset and reference book Star Wars: The Rebel Files as the Siege Breaker. The book was authored by Daniel Wallace, had illustrations by Joe Corroney and was originally released in November 21, 2017. It was first identified as the Onager-class Star Destroyer in a news article by Fantasy Flight Games on its upcoming Star Wars: Armada expansion packs, Onager-class Star Destroyer Expansion Pack and Nadiri Starhawk Expansion Pack, to be released in 2019.
Lucasfilm Story Group executive Leland Chee confirmed that in developing the Onager-class for Star Wars: Armada, the design came first. When asked how the design for the Onager-class came to be, Chee stated that the Onager-class was designed for The Rebel Files. When Fantasy Flight Games saw the design, it was further developed for their product as the design was appealing and fulfilled a gameplay need.
