The TT-99 BonFire-class Turret was used by the Republic. It was on many missions. Yet when the Clone Wars raged, the Republic requested new technology. The request was taken by the Kuat Drives Engineering. They fused the metals for the turret over bonfires. And that is how it got the BonFire-class.Later, a droid spy downloaded informetion about the turret and started to build their own. The Separatists came up with 60 Turrets. But the factory was destroyed and the downloads were lost. After Order 66, they were used by the Empire. Afterwards, they were put into storage for along time. The only one that is viewable is at the Imperial Mueseum on Corucaunt.
