Largkza was the second moon of Kilrah. The Kilrathi had transformed the moon into a massive military base. It had six carrier construction slips, a cruiser construction facility, a fighter assembly plant and barracks for the highly skilled designers and trained construction personnel.
These facilities were heavily damaged by 500 Confederation Marines of the First Marine Commando battalion. They were part of Strike Force Valkyrie when it raided the Kilrah system in 2667 as part of Operation Back Lash.
