Editing Sleeper Ship

{{:Starship-Nav-Bar-Two-2019CE}}
A [[Sleeper Ship]] is a [[Starship]], usually using sublight [[NAFAL]] propulsion, that uses one crew put into a state of suspended animation, while automation of some sort steers the [[ship]].
* They are considered to be [[Expedition Ship|K-class Expedition Ship]]s.
* Since [[civilization]]s that use such ships generally have limited means and [[technology]] for producing [[NAFAL]] [[starship]]s, most are used for [[colonization]] purposes.
* The term also applies to ships where a small living crew stays awake while the rest (...the majority of those aboard) stay in suspended animation. Most examples of [[Sleeper Ship]]s with [[FTL]] propulsion use this arrangement. {{Unpublished cite|author= [[Adrian Tymes]] }}
* There are tales of [[nanotech]] approaches that stock a ship with seeds and machines in order to build a [[civilization]] at the destination. If there actually were any ships like this, they would technically not be [[Sleeper Ship]]s, as there would be nobody sleeping on the ship, but most of the details would be otherwise identical. {{Unpublished cite|author= [[Adrian Tymes]] }}

== Description ([[Specifications]]) ==
A ship containing a full complement of personnel intended to make a (usually sub-light) journey across space.
* Since such journeys take years, or even decades, the passengers, and sometimes the crew are put into hibernation in [[Low Berth]]s for the duration of the journey.
* Such ships are smaller (and thus more affordable, and thus more common) than [[Generation Ship|Generation Ships]], where the passengers and crew live full lives during the journey.
* The two terms [[Sleeper Ship]] and [[Generation Ship]] are often, ''incorrectly,'' interchanged and used to refer to either type of ship.

=== Generation vs. Sleeper Ships ===
[[Generation Ship]]s are sometimes referred to, incorrectly, as [[Sleeper Ship]]s, which are similar, except that the majority or all of the [[passenger]]s and [[crew]] are put into [[low berth]] hibernation for the duration of the journey. {{Unpublished cite|author= [[Adrian Tymes]] }}

=== Technical Discernment ===
In cases where a small portion of those aboard are awake, it is often common to be awake in shifts. For instance, the complement might include 5 crews, each of which handles 1/5th of the voyage then wakes up the next crew before sleeping out the rest of the trip.  If the voyage takes 40 years, the crews will only have aged 8 years each, and remain available to participate in the new colony's early years. This also provides backup capability if something goes wrong, similar to the [[Frozen Watch]] but on a longer time scale. {{Unpublished cite|author= [[Adrian Tymes]] }}

There are also cases where the voyage will only take a few years (sometimes a few weeks), and while the colonists may have skills useful at the colony most of them are not useful aboard ship.  The colonists hibernate to reduce life support costs, and to facilitate use of smaller ships, while the crew remains awake for the entire voyage. In these cases, the crew - who are adjusted to shipboard life among the stars, and thus might make poor colonists - may continue flying the ship (possibly returning to where the colonists came from) after their cargo is delivered. {{Unpublished cite|author= [[Adrian Tymes]] }}

This is sometimes used to build a colony up in stages with smaller ships. As an extreme example, a ship might carry only 1,000 colonists and their equipment at a time, to a colony 1 week-long jump away from the colonists' origin, building up to 1,000,000 colonists over 100 back-and-forth trips over the span of 40-50 years (2,000 weeks, plus time to load and unload 1,000 times each). These same ships are typically capable of much longer journeys; only the logistics of scheduling multiple trips in a reasonable time span limits their range for such operations. {{Unpublished cite|author= [[Adrian Tymes]] }}

=== Strategy & Tactics (Doctrine) ===
Like most [[civilian vessel]]s, ''Expedition Ship''s are not designed for combat and should run whenever possible when facing marauders or [[pirate vessel]]s. Many are equipped with light armament and defensive suites nevertheless.

=== Supraclass Roles ===
''Expedition Ship''s typically serve the following roles: <br>

==== Size-Class Roles for Expedition Vessels ====
# [[Expeditionary Smallcraft]] (UK) (1 to 99 [[ton]]s)
# [[Very Light Expedition Ship]] (KVL) (100 to 2,499 [[ton]]s)
# [[Light Expedition Ship]] (KL) (2,500 to 99,999 [[ton]]s)
# [[Medium Expedition Ship]] (KM) (100,000 to 249,999 [[ton]]s)
# [[Heavy Expedition Ship]] (KH) (250,000 to 499,999 [[ton]]s)
# [[Superheavy Expedition Ship]] (KS) (500,000 to 999,999 [[ton]]s)
# [[Ultraheavy Expedition Ship]] (KU) (1,000,000 or more [[ton]]s)

==== Civilian Subcraft ====
Civilian [[subcraft]] (...both [[smallcraft]] and [[bigcraft]]) are carried by some of these [[vessel]]s:
# [[Barge]] (WB)
# [[Utility Craft]] (U)

=== Supraclass Archetypal Roles ===

| [[Leaping Snowcat class Safari Ship]]
| Type-K Expedition Ships are tasked to go on extended trips whether for recreation (safari), exploration (colonization), diplomacy ([[first contact]]), or other tasks requiring purposeful travelling across vast distances. {{Unpublished cite|author= [[Maksim-Smelchak]] }} 
* K = Kiswahili (Name of Terran language used in an area where many significant safari expeditions occurred. Also known as [[Swahili]])

| [[Colony Ship]]
| KC
| [[C-Jammer class Settlement Transport]]
| Colony ships, settlement transports, star arks, and the like bring a population of colonists across great distances to establish new [[mainworld]]s. Such vessels are often quite large, needing to bring all the necessities of life to the new world. {{Unpublished cite|author= [[Maksim-Smelchak]] }}  
* C = Colony

!colspan="4"| ''NOTES:'' There is semantic overlap between many of the classes and codes. Some codes organize by mission or capability, others by size and [[ton]]nage, and yet others by other characteristics.

== History & Background ([[Dossier]]) ==
[[Colony Ship]]s establish colonies on new worlds, settlements to sustain life and provide socioeconomic commerce. 

The [[Flight of the Phoenix 2800|Phoenix 2800]] was one famous [[FTL]] sleeper ship, taking 5 years to complete its multi-sector voyage.
