HK-47 instructed the spacers to invade the Kubaza Beetle Cavern and enable his AI to be transferred from the ship. 1.5 ABY, the terminal in the Republic cruiser contacted a group of spacers. The deactivated HK-47 chassis, along with the rest of the new HK-77 models, were forgotten and lay dormant after Vader and the Republic forces left Mustafar. Mass production was ready to begin when Darth Vader arrived on Mustafar and wiped out the separatist leaders, bringing an end to the Clone Wars and the separatist movement. Separatist scientists began studying design elements of HK-47 and incorporating them into their own technology, hoping to create new droid models that would help to finally defeat the Republic. When the Confederacy of Independent Systems arrived on Mustafar during the on-going Clone Wars, they discovered the wreckage and HK-47's chassis. Thousands of years later a tectonic shift exposed the cruiser.

For unknown reasons the cruiser crashed on the volcanic Outer Rim planet Mustafar.

Sometime during the thousands of years between then and the Galactic Civil War, HK-47's AI was transferred to a computer located in a Galactic Republic cruiser.
