These ships are Fanon and have popped up on the net in many Empire At War video mods.

I have added these because General Forlon will be commanding one over Duro. Recently, the location of the ships, as well as the custodians protecting them, have been provided to fleet command. After Endor, these ships remain in reserve service hidden by Dodonna after Hoth. These four ships were seldom seen or used, Dodonna choosing to hold them in reserve rather than take them against the new Imperial destroyers. As the Empire took a hold of the galaxy, Dodonna and others worked on the ground work for what was to become the Alliance to Restore the Republic. In reality, they had been given to Dodonna to hide in case Commenor needed them at a later time. Sometime before the order to assimilate all defense fleets into the Imperial fleet, these ships were sold as scrap and the paperwork was lost. Four were commissioned at the request of General Dodonna and sold to the Commenor defense fleet. Many of these ships were not commissioned and sold to third parties as scrap. The Valiant class were built in an attempt to reuse the Venator ships after the Clone Wars. The Valiant can deploy four troop regiments and supporting armor. Additional landing struts were added, giving the Valiant the ability to land and deploy troops. Sharing design principles of both the Acclamator and Venator, the Valiant had a large holding bay for planetary forces on the ventral hull. These housed the fighter wing and transports, leaving the forward bay as a holding area for larger barges and visiting craft. Two large secondary hangars were built, flanking the superstructure on both sides. Two double turbolaser cannons covered the rear of the ship, each one flanking the rear of the superstructure. Flanking the superstructure were three double heavy turbolaser cannons placed on the dorsal hull towards the aft of the ship. It housed a quad heavy turbolaser turret and six ion cannons. Another large weapons emplacement was on the fore edge of the superstructure. The Amidships Ventral bay was also removed, making way for a large ventral weapons emplacement including a quad heavy turbolaser turret, four double turbolaser cannons, and four ion cannons. Armor was re-enforced, slowing the acceleration and speed of the vessel.The dorsal sliding bay doors were removed, being replaced with armor and two weapons emplacements, each with a quad heavy turbolaser turrets, two double turbolaser cannons, four ion cannons, and a prow forward bay were created for larger craft and corvettes. Meant to be more battleship and less carrier, the troop capacity and massive hanger were turned into capacitor compartments for more weapons and shielding. Twelve Venator hulls were modernized and rebuilt, creating the ships of the Valiant Class.

As new designs came about, such as the Victory and Imperator, many commanders looked for a way to modernize the Venators. The backbone of the Clone Wars, the Venator was both carrier and battleship.
