The Yuuzhan Vong had a вЂњshipвЂќ called a вЂњWorldshipвЂќ, and not much is known about them, besides the fact that like all of the Yuuzhan Vong вЂњtechnologyвЂќ was organically-based, as in basically being lifeforms of one sort or another. I believe that the DS-II was around 200 Kilometers Diameter. The Death Star II was even larger, with a massive diameter range, from 160 Kilometers up to 900 Kilometers. The Death Star I, with a diameter of 140 Kilometers. But there is a ship even bigger than that. That ship is called the Supremacy, and it is the ONLY Mega-Class Super Star Dreadnought. Their armaments and fighter compliments are superior to the Executors and require far fewer crew than the Executor Class.You have angered a Grand Admiral! The Executor isnвЂ™t even the largest ship built! There is a class of Star Dreadnought that is 60 Kilometers on itвЂ™s longest axis вЂ“ 41 Kilometers longer than the Executer. The Viscount Class is often referred to as a Republic Super-Star Destroyer as they were designed explicitly to counter the Empire's own Super-Star Destroyers although most just refer to them as Viscounts. In 29 ABY, after the desolation of Taris by the crime lord Tyber Zann, the Viscount was sent to Taris to oversee search-and-rescue operations as well as to defend the planet from future attacks. The Viscount and its forces were then redirected to Sullust to aid in the defense of the planet. The Viscount, the first ship of the line, under the command of Bothan Admiral Traest Kre'fey, was on a deep space patrol of the mid-rim when the Shadow Wars broke out in 28 ABY.

With the aid of ex-Imperial Engineers, including many that had worked on both Death Stars, the Mon Calamari and Corellians worked to find ways to streamline the Viscount's construction process and within four years, by the time the Shadow Wars broke out, a second Viscount had just been launched with two more on the way. The retired Mon Mothma was asked to personally dedicate the vessel. Eventually, in 24 ABY, the first Star Defender was launched to the applause and cheers of people watching via holonet. By the time the Galactic Civil War formally ended in 11 ABY, the Viscount was considered to be around 35% complete. Corellian Engineering Corporation was brought in to assist. However construction was slow as the Mon Calamari Shipyards had never constructed anything of this size and scope before. Ackbar, with backing from pro-military members of the Senate, commissioned the first Viscount for the New Republic.

It took several years to develop and development was finished byВ 9 ABY. He would work closely with these engineers to develop what became known as the Viscount Project. To wit, he began reaching out to his newly liberated people on Mon Cala, to begin designing what he hoped would be the New Republic's answer to the Executor. 'This was the most ambitious project the New Republic has undertaken.ever.' 'Force willing, we'll never need it.' 'Or if we do, may it be long after we've all become one with the Force.' 'Way ahead of you, boy.' - Galen Marek and Rahm Kota regarding the Viscount.ДЇollowing the Battle of Endor, Admiral Ackbar calculated that the largest threats the Empire had left were their massive Executor Class Super-Star Destroyers.

This is one of my ships from my Star Wars Fanfiction Series: Star Wars: The Shadow Wars.
