A super-maximum security (supermax) or administrative maximum (ADX) prison is a "control-unit" prison, or a unit within prisons, which represent the most secure levels of custody in the prison systems of certain countries. This is often the most secure form of security within a certain prison system. The objective is to provide long-term, segregated housing for inmates classified as the highest security risks in the prison system—the "worst of the worst" criminals—and those who pose an extremely serious threat to both national and global security.

Characteristics and practices
According to the National Institute of Corrections, an agency of the United States government; "a supermax is a stand-alone unit or part of another facility and is designated for violent or disruptive inmates. It typically involves up to 23-hour-per-day, single-cell confinement for an indefinite period of time. Inmates in supermax housing have minimal contact with staff and other inmates," a definition confirmed by a majority of prison wardens.
Leena Kurki and Norval Morris have argued there is no absolute definition of a supermax and that different jurisdictions classify prisons as supermax inconsistently. They identify four general features that tend to characterize supermax prisons:
- Long-term: once transferred to a supermax prison, prisoners tend to stay there for several years or indefinitely.
- Powerful administration: supermax administrators and correctional officers have ample authority to punish and manage inmates, without outside review or prisoner grievance systems.
- Solitary confinement: supermax prisons rely heavily on intensive (and long-term) solitary confinement, which is used to isolate and punish prisoners as well as to protect them from themselves and each other. Communication with outsiders is minimal to none.
- Very limited activities: few opportunities are provided for recreation, education, substance abuse programs, or other activities generally considered healthy and rehabilitative at other prisons.
Prisoners are placed not as a punishment of their crimes but by their previous history when incarcerated or based on reliable evidence of an impending disruption. For example, this could be a prisoner who is a gang leader or planning a radical movement. These decisions are made as administrative protection measures and the prisoners in a supermax are deemed by correctional workers as a threat to the safety and security of the institution itself.
The amount of inmate programming varies from jurisdiction to jurisdiction. Certain jurisdictions provide entertainment for their inmates in the form of television, educational and self-help programs. Others provide instructors who speak to inmates through the cell door. Some jurisdictions provide no programming to its inmates. In a supermax, prisoners are generally allowed out of their cells for only one hour a day (one-and-a-half hours in California state prisons). Exercise is done in indoor spaces or small, secure, outdoor spaces, usually alone or in a pair and always watched by the guard. Group exercise is only offered to those who are in transition programs.
Inmates receive their meals through ports in the doors of their cells.
Prisoners are under constant surveillance, usually with closed-circuit television cameras. Cell doors are usually opaque, while the cells may be windowless. Furnishings are plain, with poured concrete or metal furniture common. Cell walls, and sometimes plumbing, may be soundproofed to prevent communication between the inmates.
The United States
The United States Penitentiary Alcatraz Island, opened in 1934, has been considered a prototype and early standard for a supermax prison. Supermax prisons began to proliferate within the United States after 1984. Prior to 1984, only one prison in the U.S. met "supermax" standards: the Federal Penitentiary in Marion, Illinois. By 1999, the United States contained at least 57 supermax facilities, spread across 30–34 states. The push for this type of prison came after two correctional officers at Marion, Merle Clutts, and Robert Hoffman, were stabbed to death in two separate incidents by inmates Thomas Silverstein and Clayton Fountain. This prompted Norman Carlson, director of the Federal Bureau of Prisons, to call for a new type of prison to isolate uncontrollable inmates. In Carlson's view, such a prison was the only way to deal with inmates who "show absolutely no concern for human life".
In recent years[when?] a number of U.S. states have downgraded their supermax prisons, as has been done with Wallens Ridge State Prison, a former supermax prison in Big Stone Gap, Virginia. Other supermax prisons that have gained notoriety for their harsh conditions and attendant litigation by inmates and advocates are the former Boscobel (in Wisconsin), now named the Wisconsin Secure Program Facility, Red Onion State Prison (in western Virginia, the twin to Wallens Ridge State Prison), Tamms (in Illinois), and the Ohio State Penitentiary. Placement policies at the Ohio facility were the subject of a U.S. Supreme Court case (Wilkinson v. Austin) in 2005 where the Court decided that there had to be some, but only very limited, due process involved in supermax placement.
There is only one supermax prison in the United States federal system, ADX Florence in Florence, Colorado. It houses several inmates who have a history of violent behavior in other prisons, with the goal of moving them from solitary confinement for 23 hours a day to a less restrictive prison within three years. However, it is best known for housing several inmates who have been deemed either too dangerous, too high-profile or too great a national security risk for even a maximum-security prison. Residents have included Timothy McVeigh, perpetrator of the Oklahoma City Bombing who was executed by lethal injection at the Federal Correctional Complex, Terre Haute on 11 June 2001; Theodore Kaczynski, a domestic terrorist otherwise known as the Unabomber, who once attacked via mail bombs; Robert Hanssen, an American FBI agent turned Soviet spy; Terry Nichols, McVeigh's accomplice in the Oklahoma City Bombing; Richard Reid, known as the "Shoe Bomber", who was jailed for life for attempting to detonate explosive materials in his shoes while on board an aircraft; Umar Farouk Abdulmutallab, the underwear bomber; Richard Lee McNair, a persistent prison escapee; Charles Harrelson, a hitman who was convicted in 1979 of killing Federal Judge John H. Wood Jr.; and Vito Rizzuto, boss of the "Sixth" Mafia "Family," released on 5 October 2012. The Boston Marathon Bomber was housed there. Deprivation of social contact and the isolation of inmates have some unintended positive and negative effects. Inmates are safer being in isolation, and prisons create more jobs for their local communities.
However, many states now have created supermax prisons, either as stand-alone facilities or as secure units within lower-security prisons. State supermax prisons include Pelican Bay in California and Tamms in Illinois. The USP in Marion, Illinois was recently downgraded to a medium-security facility. Some facilities such as California State Prison, Corcoran (COR) are hybrids incorporating a supermax partition, housing or having housed high-security prisoners such as Charles Manson.
An early form of supermax-style prison unit appeared in Australia in 1975, when "Katingal" was built inside the Long Bay Correctional Centre in Sydney. Dubbed the "electronic zoo" by inmates, Katingal was a super-maximum security prison block with 40 prison cells having electronically operated doors, surveillance cameras, and no windows. It was closed down two years later over human rights concerns. Since then, some maximum-security prisons have gone to full lockdown as well, while others have been built and dedicated to the supermax standard.
In September 2001, the Australian state of New South Wales opened a facility in the Goulburn Correctional Centre to the supermax standard. While its condition is an improvement over that of Katingal of the 1970s, this new facility is nonetheless designed on the same principle of sensory deprivation. It has been set up for 'AA' prisoners who have been deemed a risk to public safety and the instruments of government and civil order or are believed to be beyond rehabilitation. Corrections Victoria in the state of Victoria also operates the Acacia and Maleuca units at Barwon Prison which serve to hold the prisoners requiring the highest security in that state including Melbourne Gangland figures such as Tony Mokbel and Carl Williams, who was murdered in the Acacia unit in 2010.
In 1985, the state government of São Paulo created an annex to a psychiatric penitentiary hospital meant to house the most violent inmates of the region and established the Penitentiary of Rehabilitation Center of Taubaté, also known as Piranhão. Previously, high-risk inmates were housed at a prison on Anchieta Island; however, that closed down after a bloody massacre. At Taubaté, inmates spent 23 hours of a day in solitary confinement and spent 30 minutes a day with a small group of seven to ten inmates. Ill-treatment of inmates occurred on a daily basis, causing major psychological impairment.
Throughout the 1990s, and the early-2000s, Brazil faced major challenges with gang structures within its prisons. The gang Primeiro Comando da Capital (PCC) gained notoriety in the prison system and had new members joining within the prisons. Riots were a common occurrence and the gang culture became uncontrollable, leading authorities to pass the controversial Regime Disciplinar Diferenciado (RDD), a culture founded from disciplinary punishment.
The United Kingdom
Britain's Her Majesty's Prison Service in England and Wales has had a long history in controlling prisoners that are high-risk. Prisoners are categorized into four main classifications (A, B, C, D) with A being "highly dangerous" with impossibility in escaping to category D in which inmates "can be reasonably trusted in open conditions."
The British government formed the Control Review Committee in 1984 to allow for regulating long-term disruptive prisoners. The committee proposed special units (called CRC units) which were formally introduced in 1989 to control for highly-disruptive prisoners to be successfully reintegrated. Yet a series of escapes, riots, and investigations by authorities saw the units come to a close in 1998. They would soon be replaced by Close Supervision Centres (CSC), which was meant to provide relief for long-term prisons which are still used in the present day. It was reported to hold 60 of the most dangerous men in the UK in 2015.
Cost-benefit analysis of supermax prisons
There is no set definition of a supermax prison; however, the United States Department of Justice and the National Institute of Corrections agree that "these units have basically the same function: to provide long-term, segregated housing for inmates classified as the highest security risks in a state’s prison system." When making comparisons between supermax prisons and non-supermax prisons, a clear and consistent definition is crucial. As a result, applying one definition to "supermax housing" across all states and jurisdictions is very important. Things to consider include types of prisoners, facility conditions and the purpose of the facility is important to the analysis.
Consequently, it is hard to provide a cost-benefit analysis with varying facilities across the board. In these cases, a cost-benefit analysis would be beneficial in the decision to construct a facility, upgrade an existing facility, or determine whether a facility should be closed down.
Costs of operating a supermax prison
Building a supermax prison, or even retrofitting an old prison is very expensive. ADX Florence took $60 million to build in 1994. In 2010, when President Obama wanted to transfer Guantanamo Bay detainees to the Thomson Correctional Center, costs were expected to be $237 million to renovate, retrofit, and set up the center.
Compared to a maximum security facility, supermax prisons are extremely expensive to run and can cost about three times more on average. The 1999 average annual cost for inmates at Colorado State Penitentiary, a supermax facility, was $32,383. Compared with the maximum-security prison, the Colorado Correctional Center's annual inmate cost was $18,549. This is mainly due to the technology needed to further maintain a supermax: high-security doors, fortified walls, and sophisticated electronic systems. There are higher costs for staffing these facilities because more people must be hired to maintain the buildings and facilities. These costs are paid by taxpayers and depend on the jurisdiction of the prison. Federal prisons are taken by federal taxes, while state prisons are provided for by the state.
Furthermore, there are many costs that are harder to measure. Supermax facilities have had a history of psychological and mental health issues to their inmates. These psychological problems present an additional layer of burden to society. Additional costs to society are incurred when inmates have a hard time readjusting to normal life after release, and inmates may even be more inclined to commit even worse offenses to society.
Benefits of a supermax prison
Supermax facilities better prevent inmates from escaping, and offer greater protections against inmates hurting one another than non-supermax prisons do.
Supermax and Security Housing Unit (SHU) prisons are controversial. One criticism is that the living conditions in such facilities violate the United States Constitution, specifically, the Eighth Amendment's proscription against "cruel and unusual" punishments. In 1996, a United Nations team assigned to investigate torture described SHU conditions as "inhuman and degrading". A 2011 New York Bar association comprehensive study suggested that supermax prisons constitute "torture under international law" and "cruel and unusual punishment under the U.S. Constitution". In 2012, a federal class action suit against the Federal Bureau of Prisons and officials who run ADX Florence SHU (Bacote v. Federal Bureau of Prisons, Civil Action 1:12-cv-01570) alleged chronic abuse, failure to properly diagnose prisoners, and neglect of prisoners who are seriously mentally ill. The suit was dismissed.

In Brazil, the "regime disciplinar diferenciado" (differentiated disciplinary regime), known by the acronym RDD, and strongly based on the Supermax standard, was created primarily to handle inmates who are considered capable of continuing to run their crime syndicate or to order criminal actions from within the prison system, when confined in normal maximum security prisons that allow contact with other inmates. Since its inception, the following prisons were prepared for the housing of RDD inmates:
