Stahl Arms Deep South was the main headquarters of Stahl Arms. It was one of the foremost weapons research and development centers for the Helghan Empire, creating very advanced and powerful tools of destruction for the war effort, prominent examples of which are the StA-X3 W.A.S.P. Launcher and the StA-5X Arc Cannon.
In the aftermath of Operation Archangel, captured ISA soldiers were sent to Deep South to be used as living test subjects for the corporation's weapons testing program, and other painful and lethal experiments at the hands of the corporation. Chairman Jorhan Stahl later had ISA prisoner Captain Jason Narville to be publicly executed at Deep South. However, Tomas Sevchenko and Rico Velasquez infiltrated the facility and foiled the execution, and rescuing Narville. It was also there that Tomas and Rico learned about Stahl's plans for his invasion of Earth.
