What do "supermax" facilities refer to?

"Supermax" facilities are highly secure correctional institutions designed specifically to house the most dangerous and violent offenders. These facilities utilize stringent security measures to control and manage inmates who pose significant risks to others, including other inmates and correctional staff.

The environment in supermax prisons typically includes solitary confinement, extensive surveillance, and limited interaction with staff and other inmates, all intended to prevent disturbances and escape attempts. Inmates in these facilities often have committed serious crimes, such as terrorism, murder, or continuous violent behavior, which necessitates such heightened levels of security and control to ensure safety within the institution and the surrounding community. This classification as high-security prisons distinguishes them from lower-security facilities that accommodate less dangerous individuals.
