The Pride of the Core began construction shortly after the Clone Wars broke out. Kuat Drive Yards had cut all ties with the now Separatist aligned Techno Union and started to exclusively produce for the Galactic Republic. The Mandator-II-line would be an upgrade from the Mandator-class Star Dreadnaught. Near the end of 20 BBY the Pride of the Core had finished production. Concurrent to this event was the Separatist assault on the Core Worlds, Operation Durge’s Lance. It wasn’t long before the Pride of the Core got its baptism of fire at the planet of Skako. A desperate Republic was trying to defend the beleaguered world from a Separatist attempt to relief the siege. The arrival of the Pride of the Core marked a turning point in the battle. Causing considerable losses amongst the Confederate Third Fleet, forcing the fleet under command of General Grievous to retreat. The Battle of Skako was seen as a turning point during Operation Durge’s Lance and showed the succes of this new class of ships.
