Prison Ship

Go To
A Lictor-class dungeon ship

A Prison Ship is a penitentiary, correctional facility, or jail that typically moves under its own power (though some prisoner transports or jail vessels have to be towednote ). Often featured to highlight the questionable moral standards of the villains or enemy force, the heroics of protagonist in withstanding the cramped conditions, a setting for a prison story, or to add movement and interest to what would otherwise be a static setting. It's also an easy way to set up The Alcatraz; in the middle of the ocean or in space, there's nowhere to escape to.

For the purposes of this trope there are two types of Prison Ship:

  • The Prison Transport: this modestly-sized vessel is either designed or modified to transport prisoners between facilities, not hold them permanently. The transport spaceship in Pitch Black is not an example as it had only one prisoner strapped in; the rest of the occupants were paying passengers. Conversely the prison transport in the Lexx miniseries would count because his divine shadow is just that thorough. In fiction, there are often depictions of criminal gangs ambushing or hijacking the prison transport to free their comrades, or to capture a rival gang leader who they want to "deal with". A Bounty Hunter may use this kind of ship to hold several targets while transporting them to an actual prison.
  • The Jail Ship: often a setting in and of itself, this large vessel is usually purpose built to hold prisoners permanently, often for unscrupulous deeds committed outside of the jurisdiction. Jail ships include those that are mobile under their power and old demobilized ships that are no longer fit for military use, and which have been converted to become floating jails (they are kept at a dock).
    • Jail spaceships need to be large enough for cells (or stasis pods with life-support equipment if the prisoners are in Human Popsicle mode), guard quarters, guard stations, food preparation facilities, recreational areas, an infirmary, and so on. As well, they need some self-defense capacities to protect the Prison Ship from attackers who hope to free their comrades.

Despite the name of the trope, it covers any mobile jail or prison transport, including trains and transport planes.

Not to be confused with Shipping between prisoners.

  • Batman: In Gotham, Blackgate Prison (located on an island in the harbour) has used a modified barge as overflow housing for less dangerous prisoners. Warden Zehrhardt bitterly described it as a temporary solution... of twenty years and counting. Cluemaster once planned a mass breakout that involved cutting the barge loose and having it picked up by modern-day pirate Cap'n Fear.
  • Les Passagers Du Vent contains both types at the time of the American War of Independence - a French slaver and a British prison hulk.

  • Star Wars:
    • Star Wars: Doctor Aphra: During the "Catastrophe Con" arc, Aphra is imprisoned by the Imperials on Accresker Prison, which is a unique spin on this trope. It's actually the hulks of several ships magnetically strapped together and tugged around by a Star Destroyer, whose prisoners are press-ganged to act as expendable boarding parties whenever the Imperials raid a new ship. The prisoners aren't even restrained or placed into cells, since escape is impossible — the ship pulling it is connected only through long cables, none of the component ships has so much as anything useful for building a functioning vessel left in it, and the prison never even approaches planets.
    • Star Wars Legends: In Dark Empire, Luke ends up imprisoned in a "dungeon ship" especially designed to hold Jedi.
  • Wonder Woman (1987): The Sangtee Empire has large vessels dedicated to the transport of prisoners, specifically non kreel and non-natives caught within the borders of their Empire who are then enslaved and shipped off to prison planets to mine. They're called slave ships by both the Empire and the rebels.
  • Zoids: The Marvel UK version follows the story of the survivors of a human Prison Ship which crashed on what they think is an uninhabited planet but is in fact Zoidstar, former capital of the Zoidaryan Empire.

  • The Dred Chronicles are set on a prison ship called Perdition, in permanent orbit in an isolated system. It's where the Conglomerate dump people who they judge beyond any attempt at rehabilitation, and it's largely lawless — there are no cells and no human guards.

  • An early episode of Avatar: The Last Airbender has a Fire Nation prison shipyard, a massive oil-derrick-like construction built way out in deep water.

    Real Life 
  • Truth in Television, of course.
    • These were often older decommissioned ships, kept permanently at anchor and used because of the easily available space, versus having to build a custom prison. This was especially useful during times of war, where they might temporarily have many more prisoners than they would on a long-term basis in peace time.
    • Note that decommissioned ships have seen similar use for a variety of other purposes, to include housing for military recruits, defensive outposts, and as museums (often centering on the career of the ship itself, natch).
  • The Vernon C. Bain Correctional Center in New York City. It is a barge permanently moored to a pier in the Bronx that currently holds around 800 inmates, designed to handle medium to maximum security inmates.
  • Prison ships have long been associated with the English army. On the eve of the Battle of Waterloo, Napoleon referred to British prison ships to rally the anger of the French soldiers: “Soldiers, let those among you who have been prisoners of the English describe to you the hulks [rotting, old prison ships], and detail the most frightful miseries which they endured!”
  • The practice of chaining slaves, and cramming them into ships' cargo holds is as old as maritime trade.
  • During WWII, Allied POWs' were crammed into "Hell Ships," to be transported across Japanese occupied territory (known to Japan as the "Eastern Co-Prosperity Sphere") to be held in hellish prison camps, or as manual labor. Being unmarked, Allied naval forces would often attack and sink these "Hell Ships," thinking they were filled with supplies or combat troops. Considering the absolutely horrific conditions aboard these vessels, they may as well have been.
