Its weaponry was more powerful than other Star Destroyers due to the fact that energy from the ship's hyperdrive was transferred to its weapon systems. It was a common placement for junior officers due to its role as a Core Worlds patrol ship.[5]Thunderflare was detached to the Elrood sector where her patrols were restricted to the Derilyn system. And given that the Elrood sector is located in the Outer Rim Territories it is unclear how or when Thunderflare was on patrol in the Core Worlds.
Sometime before the Battle of Yavin, Khurgee served aboard the Thunderflare, where he was honored for bravery after rescuing five officers from a shuttle crash. He was later assigned to the first Death Star as a docking-bay security officer.[7]
In 4 ABY, the Thunderflare was assigned to the defense of Death Star II's construction. It later fought at the Battle of Endor.[1] As part of Death Squadron, the ship survived the battle. Captain Pryl refused to obey the new fleet commander, Gilad Pellaeon, and decided to return in the Elrood sector with her ship.[6]
