Keldabe-class battleships were designed by MandalMotors, a Mandalorian ship building organization. The name Keldabe comes from the capital of the planet Mandalore. Keldabe-class ships were used by the Zann Consortium after he corrupted the planet Mandalore.
Other than a vast amount of Turbolasers and Ion cannons, Keldabe-class battleships have the ability to drain shield power from enemy vessels, and convert it into its own shield and Weapon systems. It also possessed shield disrupting Mass Drivers.
Being one of two Capital ships available to the Zann Consortium, the Keldabe among many is considered the most powerful Consortium space unit. In fact, it is possible to take down a level 5 space station with just one Keldabe accompanied by Bossk. The shield leeching weapon is great against frigates and capital ships, easily able leave a shielded target vulnerable to attack within 10 seconds or so.
The Keldabe has no real weakness except it's vulnerability to bombers and some capital ships, such as Home One. However they do take a while to build and are not to say pretty pricey.
