From Warhammer 40k - Lexicanum
The Graviton Destructor is a type of large Graviton Weapon mounted on Imperial Warhound and Reaver Titans.
This advanced and highly destructive weapon system was much more common during the Horus Heresy than the modern setting, and had enough force to rip apart even enemy Titans. Reaver Graviton Destructors are mounted on the Titan's back, allowing the weapon to have a 360 degree firing arc. Warhound Destructors meanwhile, are mounted as arm weapons.
