DY - 100 class The DY - 100 class was an early design of Earth space vessel s that were in operation during the late 20th century . History . The ships were especially designed for interplanetary travel . They had simple nuclear powered engines and were equipped with artificial gravity . They utilized transistors as components . DY - 100 ships were launched into orbit with booster rocket s . In the 1990s , this class of spaceship was considered to be one of the most advanced . At least some of the DY - 100 ships were sleeper ship s . In those a crew of at least 85 could be placed into suspended animation inside life support canisters prior to liftoff . The life support of the ship was turned off for the journey . The use of suspended animation was necessary up to approximately 2018 , as it took years to travel from planet to planet in the solar system prior to that . The production of DY - 100 class ships began before 1996 and ended some time before the year 2000 . A later generation of the class , the DY - 500 , was similar in configuration and some 23rd century Human s had trouble telling them apart , as did Captain James T . Kirk in 2267 , before being corrected by Spock . ( ) A model of a DY - 100 appeared on a window sill of the office where Rain Robinson worked , at the Griffith Observatory in California in 1996 . She also had a photograph of the launch of a DY - 100 attached with tape to a cabinet . ( ) A photograph of the same DY - 100 launch was in the 602 Club , along with many other space achievements , like the NX - Alpha , the " Phoenix " , and the . ( ) Appendices . Background information . All of the DY - 100 ships were probably not sleeper ships , as the crew of the " Enterprise " was surprised to discover the " Botany Bay " to be one . That contradicts a bit with the computer display of , where the image of the ship is specifically labelled " DY - 100 Sleeper Ship " ( though the graphic might specifically refer to the " Botany Bay " ) . The art department of tried to convince the producers of that series to include the DY - 100 class in the show . However , the producers refused to do so , believing this class looked too similar to a pencil . It is stated in the reference book that significant improvements in sub - light propulsion technology led to abandoning of DY - 100 ships . The original version of featured a DY - 100 class " Woden " as a Federation freighter . This appearance would indicate some of these ships were adapted into service by the Federation and remained in use at least as far as the 23rd century . Due to the of the remastered version , it is impossible to determine if this was the case . Memory Alpha lists the " Woden " as an starship , for the sole reason it was a more recent appearance from the production point - of view . In " Star Trek Spaceflight Chronology " , it is stated that DY - 100 was the first mass - produced spaceship of Earth . This production began in 1996 . There were cargo , fuel and passenger containers the ship could carry . In the standard configuration , it was used between Earth and Luna . In an uprated mode , it was able to take man to Mars . A journey to Mars , when the suspended animation was used , took 937 days . In the " Spaceflight Chronology " , timeline specifications are given of an SS " Copernicus " of the DY - 100 class . It served from 1995 to 2020 . Specifications were length 100 meters , weight 2 . 72 million kilograms , ship ' s complement 22 , and chemical / fission propulsion . Only the overall shape is similar to the " Botany Bay " . The " Copernicus " is probably intended to be the prototype of the class . Unlike the " Botany Bay " , the " Copernicus " had a built - in engine pack of six chemical boosters for lift - off . There is a discrepancy with the text and graphics , as the graphics show only four boosters . Studio models . Design . The DY - 100 was designed by Matt Jefferies . In sketches , it was referred to as an " obsolete tramp space freighter " or an " antique space - freighter " . In fact , Jefferies once stated , in , " " The " Botany Bay " was actually designed " before " the " Enterprise " . It was a little idea that popped up and was labeled ' antique space - freighter ' . Later on , we made it look like something else – a vehicle from the early 2000s . " ( " " , issue 4 , p . 4 ) One sketch also included the numbers 418 on the hull of the ship . Jefferies was pleased with the notion of modular shipping crates that could be automatically loaded and unloaded without requiring Humans to venture into space . In the sketches , Jefferies envisioned that three additional cargo containers could be attached to complete the middle section arrangement . In fact , judging from the actual model , it appears that even a second set of containers could be attached behind the first . ( " The Art of Star Trek " ) In the original script of , dated , this class was called " CZ - 100 " and almost perpetuated into the final script . In effect , author James Blish , forced to work from non - final script drafts at the time , had to adhere to the " CZ - 100 " designation in a 1968 novelization of the episode , which he wrote , indicating that the class change had been a late decision . Jefferies sold off his original design sketches on in Profiles in History ' s " The Star Trek Auction " , in order to raise funds for the charitable organization " Motion Picture and Television Fund " . Physical models . The studio model of the DY - 100 class , measuring 43×18 ( aft section ) inches , was mostly constructed out of wood , as was usual in that era , embellished with miscellaneous model kit parts and metal components . The leading edge of the " sail " ( a naval term for the tower structure found on most submarines ) features a corrugated metal foil and the engine pod includes metal " antennas " and masts . The model was not internally lighted and was finished in a brown / red - gray hue , though that finish was washed out into an overall gray on screen , due to bright lighting conditions in the studio and the use of the blue screen filming technique which caused light bouncing off the screen onto the model , an effect known as " blue spill " . While not built by Jefferies , he did add the weathering on the model . Upon completion , the model was sent to Linwood G . Dunn ' s Film Effects of Hollywood , where the only footage of the model was shot , its one later appearance as the " Woden " in the original airing of being stock footage of that shoot . ( " Cinefantastique " , Vol . 27 , No . 11 / 12 , pp . 70 - 71 ) In the remastered version of the episode , the footage of the " Woden " was replaced by a newly constructed CGI model . The table - top model – smaller than the original and outfitted with booster rockets , used in the post - TOS references , first appearing in a Photoshopped launch photograph in " Star Trek Chronology " and subsequently in – was built by Greg Jein . ( ) The launch photo made subsequent in - universe appearances as a wall ornament in the episodes , and , the latter of which also featured the model itself as a desktop model in Rain Robinson ' s office . The ( framed ) photograph itself , part of a set of four , was offered up for auction as , in the " " auction , estimated at US $ 200 - $ 300 , and was eventually sold on , with a winning bid of US $ 3 , 000 ( US $ 3 , 600 including buyer ' s premium ) . Greg Jein , a life - long fan of , was singularly well suited for constructing the desktop model , as he was the owner of the original studio model . Jein had the original model over at his workshop in for refurbishment , where amongst others he accentuated the brown - gray hull color . It has made few public appearances , the first time , directly before its refurbishment , in the 1 - 3 April 1988 " Equicon ' 88 Science Fiction Convention " held in Los Angeles , and after its refurbishment for the last time in when Jein loaned the model out to the for their 1992 - 1993 " Star Trek Smithsonian Exhibit " and its 1993 - 1994 follow - up exhibition at the Hayden Planetarium , New York City . CGI models . For the 2006 remastered version of TOS , a CGI variant of the model was used at CBS Digital , where digital animators worked with the model under the supervision of Niel Wray and David Rossi , for representation of the craft in its respective episode . The model was built by Finnish fan and digital modeler Petri Blomqvist , and was bought from him by CBS Television Studios for use in the series . Blomqvist ' s work was brought to the attention of Wray and Visual Effects Supervisor Michael Okuda by Technical Consultant Gary Kerr . The quality of his work was a compelling reason for the acquisition , as it saved valuable production time . Nevertheless , the digital animators still had their work cut out for them as Blomqvist ' s model was constructed in software , whereas they used CGI software at the time , and had to translate the digital model from one format into the other , which inevitably led to some information loss . Additionally , they had to cut down on the resolution level of Blomqvist ' s highly detailed high - resolution model , in order to speed up computer rendering time . It , and the other models CBS bought from him for the project , has earned Blomqvist an official " Technical Consultant " credit . ( " Sci - fi & fantasy modeller " , Vol . 26 , pp . 49 - 50 ) Regarding the remastered version of the " Botany Bay " , according to Michael Okuda , " " The top of the ' conning tower ' now has a tiny circular docking port , very similar to those used on the real - life International Space Station . The docking port was added at the suggestion of a former NASA engineer who noted that a spacecraft built in 1996 would probably have included such equipment to dock at the station . " " Previously , in , Doug Drexler had already built a CGI model of a DY - 100 class vessel for a fan film in the " Star Trek : New Voyages " series . His model was later used for licensed " " calendars and a book derivative of those publications . A new CGI model was built by former Foundation Imaging employee Jose Perez in for a " Fleet File " article in ( pp . 62 - 65 ) . Apocrypha . In a short story in the " Enterprise Log 4 " comic book an unnamed DY - 100 class ship was depicted with the registry number FWB 52 . The ship was part of a fleet of DY - 100 class ships that were used to colonize planets in the Sol system .
