This WWW Holonet site fully details the specifications for the SSD Avenger, Flagship of the Dark Jedi Brotherhood, a SubGroup of the Emperor's Hammer.  The SSD Avenger is another crowning example of superior Imperial war engineering at its peak.  Prior to her current duty, the SSD Avenger served as the Flagship for the Fleet until the arrival of the SSSD Sovereign.

The Super-Class Super Star Destroyer (SSD), as excerpted from the Imperial Sourcebook; Greg Gorden; West End Games; June, 1994; pp. 62-63)...and as posted in the Emperor's Hammer Fleet Manual; GARonin@aol.com, 1996).

"Except for the Death Star battle station [and the Eclipse and Sovereign classes of Super Star Destroyers], the Super-class Star Destroyer is the largest warship ever constructed. Five times the length of an Imperial Star Destroyer, each carries more than a quarter million troops and crew.

Over 1,000 turbolaser batteries, ion cannons, and tractor beam emplacements dot the eight kilometer length. These vessels are like a fleet unto themselves. Twelve squadrons of TIE class fighters (two Wings) await within the huge confines of the massive ship. Other carried vessels bring the total aboard the Super Star Destroyer to over 200 ships.

Even more weapons of destruction are within the Super Star Destroyer, including a full corps of stormtroopers and other soldiers, 25 AT-AT walkers, 50 AT-STs, and various other ground assault vehicles. In addition, the ship carries three pre-fabricated garrison bases for immediate deployment.

The Super-Class Star Destroyer is the dream of the Emperor and the epitome of his new navy. It represents the best and newest vessel available in the Imperial inventory. It is a command ship, a space-going headquarters from which to guide planetary invasions, space battles, and the like.

Four of these massive vessels are now in service. The first, Executor, was presented to Lord Darth Vader by the Emperor to serve as his personal flagship.

[The second prototype, the SSD Avenger, constructed secretly by Palpatine's engineers, was brought online shortly before the Battle of Endor to serve the newly commissioned Emperor's Hammer Strike Fleet. The SSD Avenger was christened in honor of her infamous namesake, the ISD Avenger, which served with the late Dark Vader's personal Star Destroyer Squadron. The SSD Avenger, after serving for approximately one year as Flagship of the Emperor's Hammer Strike Fleet, now serves as the Flagship for the Dark Brotherhood.
