Fort Rozz was Krypton's maximum-security prison. It was previously located within the Phantom Zone, but followed Kara Zor-El's pod, making its way to Earth, where it crashed in Nevada. Supergirl later lifted Fort Rozz into space when the prison was used to power Myriad.
Fort Rozz resided in the Phantom Zone. However, after Kara Zor-El's pod unknowingly entered the Zone, the prison followed along as it exited the Phantom Zone. As they reached Earth, Fort Rozz crashed in to a field in Nevada, releasing its prisoners.
Following the crash the D.E.O. downloaded the database of the crashed prison ship, and used its own stealth technology to conceal it, cutting off the area and masquerading it as a nuclear test zone. It was later revealed to Alex by Non that Fort Rozz became his and Astra's base of operations.
After Myriad was stopped by Kara. It was revealed that the source was coming from Nevada, where Sam Lane explained that months after it crashed they obtained what they could and then used its own stealth technology to hide it. He also said the area was quarantined as nuclear testing site and as such was declared off limits.
Following the death of Indigo and the defeat of Non, the only way to prevent Myriad from killing everyone on Earth was to launch Rozz itself into space. At the risk of her own life Kara lifted Fort Rozz into space and pushed it away from Earth, towards the Sun.
