The Ranger fired the opening shot of the battle for Praesitlyn when it unleashed a salvo of unguided MG1-A torpedoes, removing a Separatist warship from the fight. During the battle, it was boarded by battle droids deployed from a skirmisher ship which had attached to its hull. Over one hundred crewmembers were killed, including the medical staff and many engineers, but Halcyon managed to drive the droids off, saving the ship and remaining crew. However, since the damage to the Ranger rendered it unable to participate further in the battle, it was scuttled.
