On February 12, 2025, the companies Cummings Aerospace and ATRX, both based in Huntsville, Alabama, partnered to develop an unmanned hypersonic drone. The drone will be a new variant of the Hellhound subsonic weapons system, which Cummings Aerospace is currently developing for the US Army. The collaboration focuses on integrating ATRX’s Air Turbo Rocket (ATR) propulsion system into a proven airframe, enhancing the Hellhound's performance to achieve supersonic and hypersonic speeds.
