Constitution class ( alternate reality ) The " Constitution " - class was launched by Starfleet in the latter half of the 23rd century in the alternate reality . The " Constitution " - class was in the of starship s . ( ) History . The alternate " Constitution " - class dates back to at least 2255 with the construction of the USS " Enterprise " in Riverside , Iowa on Earth . The design of the starship class markedly differed from its prime universe counterpart following the temporal incursion by Nero and the destruction of the in 2233 . ( ) Following its launch in 2258 , the " Constitution " - class USS " Enterprise " served the in a variety of tasks , including survey missions and military operations . The class wasn ' t placed into long duration service until the " Enterprise " was assigned a five - year mission after 2259 . ( ) In that year , a space dock manifest display graphic in the office of Admiral included two " Constitution " - class icons identified as AF and VH - 5 . ( , " production art " ) In 2263 a second " Constitution " - class vessel , the USS " Enterprise " - A was under construction at Starbase Yorktown . That same year , the " Enterprise " itself was destroyed by Krall and his Swarm ship s in the Battle of Altamid . After Krall ' s defeat , the " Enterprise " - A was finished and given to the crew of the original " Enterprise " as their new starship . ( ) Physical arrangement . The " Constitution " - class starship followed the traditional saucer section - engineering section - warp nacelle layout common to most Starfleet vessels , but dwarfed in size many starship classes in service alongside it . Where the prime universe " Constitution " - class of the same period featured a similar , but geometrically simplified construction , the alternate " Constitution " - class displayed a more organic physical arrangement . The hull had iridescent plates and a subtle Aztec pattern . Escape pods could be launched from the port side of the neck . ( ) The ship was capable of saucer separation and could be manually separated from a console located at the physical division between the primary and secondary hulls . ( ) The uppermost section of the ship composed the primary hull - or the saucer section . The saucer section was joined to the engineering hull by a stout " neck " that terminated along the dorsal side of the engineering hull fore of the shuttlebay , which was able to hold at least twenty shuttlecraft despite being shorter than the ship ' s bow . By 2263 , the ship had a longer and more narrow neck among other structural modifications made over the course of its service . ( ) The engineering hull was conical in shape , capped by the main deflector to the fore and the main shuttlebay to the aft . The shuttlebay 2 launch bay door was located forward of the main shuttlebay on the starboard side below the warp nacelle pylon s . The deflector dish ' s center would open and close when entering and exiting warp . The shuttlebay and flight decks comprised a large portion of the engineering section as did main engineering and its related hardware . ( ; ) The ship ' s two warp nacelles were mounted by pylons to the port and starboard sides of the ship ' s engineering hull , each at a near - forty - five degree upward angle , fore of the ship ' s flight deck doors . The nacelles featured a flared housing around the Bussard collector s , which dimly glowed blue , and the aft section contained components that extended and retracted when entering or exiting warp . The uppermost section of the nacelles were parallel in height to the ship ' s bridge . The life support center of this class was located aft of the warp nacelles . ( ) Inside the Constitution - class , upper sections were predominantly white with polished black floors . A large , circular atrium connects corridor s to walkways that allowed crew members to cross the lobby with a vertical view up to a dome at the top of the ship ' s primary hull . The lower decks progressively displayed less aesthetic design . Crewman workstations often had little personal space to work in . The engineering decks consisted of conduits , tanks , and catwalks spanning each section . Ladders located in corridors allowed crew members access to spaces above and below their current location . ( ; ; ) Command and control systems . The " Constitution " - class ' s primary command center , the main bridge , was located on top of the vessel ' s primary hull , on A Deck . From here , the commanding officer supervised the entire starship ' s operation from the command chair , located behind the helm and navigation console s , and was flanked on all sides by stations controlling the vessel ' s primary functions . A large window augmented with computer displays served as a viewscreen , located at the fore of the bridge . Piloting and navigation functions were carried out at the helm console , located in the center of the bridge . This console consisted of three main sections – navigation and ops stations and primary tactical control . Behind and flanking the captain ' s chair were two forward - facing workstations for a junior science officer ( port ) and a junior communications officer ( starboard ) , supplemented by free - standing data screens . The senior science officer ' s and com officer ' s stations were located along the starboard back wall of the bridge . Numerous other stations occupied the walls of the bridge as well , generally populated by engineering division crew members to starboard and science division personnel to port . The bridge also featured a turbolift along the aft - port wall and at least one airlock doorway to the ship ' s corridor s . All operations on the bridge and elsewhere aboard the " Constitution " - class vessel were performed on touch - screen consoles and displays . The ship ' s primary computer core was capable of being linked to cybernetic personnel for analysis . ( ; ; ) By the year 2263 , two computer console stations at the starboard and port sides of the viewscreen were replaced with access hatches to Kelvin pod s - single man escape pod s . These hatches provided easy egress to command crew during emergency evacuation situations . ( ) Propulsion systems . The " Constitution " - class cruiser was outfitted with a single twin - exhaust impulse drive unit mounted at the back of the saucer section where the primary and engineering hulls join . The saucer section of the ship was also fitted with numerous ventral RCS thrusters which could operate in space , in a planet ary atmosphere and - if required - within a planet ' s ocean . ( ; ) Warp propulsion was powered by the warp core that comprised of multiple warp reactor s . Energy from the matter / antimatter intermix was fed to the two warp nacelles . When going to warp , the impulse reactors would deactivate and the tail of the warp nacelles would expand when the ship jumped to warp speed . The multiple warp reactors could be ejected in cases of extreme emergency . Unlike the ship ' s prime reality counterpart , both impulse and warp drive were regulated from the bridge , with engineering serving as monitoring and maintenance mid - flight . If not disengaged , external inertial dampener s will negate acceleration to warp velocity . ( ) By 2259 , the several smaller reactors were replaced by one large warp core that was housed in a large hemispherical containment unit , with a large electrical coupler at its center allowing distribution of power to the rest of the ship . The warp core was isolated from the rest of engineering by several radiation doors . Sometime later , following nearly a year of repair , a wider , single - exhaust impulse engine was installed on the " Enterprise " . The fins on the warp nacelles were also refitted with new sets of warp drive components . ( ) Further modifications were made before 2263 , replacing the warp nacelles with similar but smaller , thinner units and the nacelle pylon s were elongated and swept back away from the primary hull . ( ) Engineering . Main engineering was aesthetically bare - bones . The entire section was occupied by and controlled machinery required to keep the ship operating . Pipes , conduits , and tanks typically occupied the floor while catwalks spanned the space overhead . The original warp core design consisted of multiple dilithium crystal chamber s , which were replaced a year later with a single warp core unit . ( ; ) Tactical systems . Phaser turrets . The saucer section of the " Constitution " - class was armed with six phaser bank s , all with twin phaser turrets . Each of the twelve ball - turrets was capable of emitting a rapid fire barrage of phaser blasts . The banks were located on the dorsal and ventral sides of the saucer section . The phasers could be used for assault on an enemy ship or as point defense against enemy torpedo es . ( ) Following the refit of the " Enterprise " in 2259 , the ship was later received additional phaser banks on both ventral and dorsal sides of the saucer section in total number twelve phaser banks . ( ) Torpedo launchers . The torpedo bay and main forward torpedo launcher were located on the flared section of the neck connecting the primary hull and the secondary hull , and at least twelve photon torpedo es could be loaded simultaneously into torpedo tube s . The torpedoes could be fired rapidly in a barrage from the launcher . The ventral aft torpedo launcher was located at the bottom midsection of the secondary hull . ( ) A weapons bay was located on the deck of the engineering section with large broadside torpedo tubes on both sides of the secondary hull along the longitudinal axis . These tubes were capable of being loaded with the larger new advanced long - range torpedo es developed by Section 31 of Starfleet in preparations for a war with the Klingon Empire . After the Enterprise was repaired , the weapons bay and torpedo tubes were seemingly removed . ( ) Deflector shields . In 2259 , the " Constitution " - class was equipped with metaphysic shield s as a part of its defensive array . The shield strength of the ship was indicated by diburnium - osmium levels that gave the ship protection from threats , such as phaser and photon torpedo fire from enemy targets . Shielding was divided into bow and aft deflectors . ( , " display graphic " ) Armory . There was at least one armory located on board the " Constitution " - class , accessible from a standard corridor . This area provided access to numerous phaser s and phaser rifle s of varying configurations , attached to the bulkhead for access by security personnel . ( ) Brig . A large brig was located aboard " Constitution " - class vessels during the 2250 s . An open , circular section accessible by two corridors , the brig featured at least two cells protected by transparent aluminum . Two guard stations were positioned at slightly sunken computer consoles located at the center of the compartment . The cells themselves were characterized by two benches on either side , but little else in the way of accommodations . ( ) Communications room . A relay room located behind the deflector dish , this area supported the communications station on the bridge as well as certain engineering functions . Crew members sat and stood at various stations set against two rows of large , cylindrically - shaped tanks . ( ) A warp power manual override switch was located in a console in this area . ( ) Med bay . The medical facility was known as " med bay " and was located within the saucer section of the ship . The med bay was characterized by a blue and orange color scheme and featured a lab area and numerous biobed s able to accommodate more than a dozen patients . The med bay was accessible from both a standard corridor and a direct turbolift . ( ; ) Transporter systems . The transporter room aboard the " Constitution " - class occupied a corridor room of the saucer section . The back of the room was a circular alcove containing the transporter pad . The blue steps of the transporter glowed red when in use . The transporter control system was located just inside the room ' s entry , and was shielded from the transporter pad by either a glass or transparent aluminum wall . The control system was illuminated by lamps attached to the control board by flexible necks . Transporter target lock was attained by using a joystick control to lock onto the target ( s ) designated for transport . Operation of the transporter s typically required that the target not move , relative to its own surroundings , before it could be dematerialized . The system could be used to lock on to a moving target and negate the target ' s momentum upon rematerialization , but using the system in such a way required a highly skilled operator . The transporter chief typically wore a miniature heads - up display in front of the left eye . ( ; ; ) Recreational facilities . There was at least one bar on board the " Constitution " - class . A small view port was located here with an adjacent table and chairs . Across the room featured additional seating . ( ) Archive vault . The archive vault was a section devoted to the storage and study of artifacts was located aboard " Constitution " - class starships during the 2260 s . This area was distinguished by curved bulkhead s with numerous slots and shelves for storage . A computer station was located in the center of the section for scanning and cataloging of items before they were securely stowed . ( ) Appendices . Background information . Exterior . For the " Enterprise " depicted in the " Kelvin Timeline " films , and the " Constitution " - class was designed by Ryan Church , based on the original design , which was conceived by Matt Jefferies . On the " Starships " Blu - ray featurette , it is acknowledged that the redesign has elements of both previous versions of the " Constitution " - class " Enterprise " , from and the first six " Star Trek " films respectively . The redesign was also inspired by the sleekness of a car . For " Star Trek Into Darkness " , Industrial Light & Magic digitally generated the " Constitution " - class model using a new CGI renderer – Solid Angle Arnold , in conjunction with the Katana lighting tool released by computer graphics and visual effects software developer The Foundry . ( " Cinefex " , No . 134 , p . 72 ) For its appearance in " Star Trek Beyond " , the digital model of the " Enterprise " was passed from ILM to Double Negative which handled the bulk of the visual effects for that film . Retaining upgrades given to the model after its " refit " at the conclusion of " Star Trek Into Darkness " , Double Negative further modified the ship under the guidance of director Justin Lin . According to VFX Supervisor Peter Chiang : " " There ' s a big story point about the vulnerability of the ship . Justin wanted it to resemble a little more the original 1966 " Enterprise " , where the nacelles and neck were quite thin . " " ( " Cinefex " , No . 148 ) Interiors . The bridge , upper corridor s and turbolift , transporter room , and sickbay of the revised " Constitution " - class were built as sets at Paramount Pictures . According to Production Designer Scott Chambliss and others on the " Star Trek " film ' s Blu - ray and " Star Trek - The Art of the Film " , the ship ' s white upper levels were inspired by ' s architecture , an approach which evidently continued to the brig in the sequel . Noted Roger Guyett , " " We had somehow managed to negotiate the dangerous waters of redesigning the " Enterprise " – adding detail and making it feel more modern . " " Whereas re - envisioning the " Constitution " - class for the film " Star Trek " represented a major design challenge , the class remained relatively unaltered in " Into Darkness " , though the filmmakers of the latter movie decided to explore the design in more detail . " " We used the same sets , redressed and updated , " " noted Visual Effects Producer Ron Ames . ( " Cinefex " , No . 134 , p . 72 ) A new addition to the " Enterprise " sets was a large , circular atrium connecting the traditional corridor sets with a vertical view up and down the height of the ship provided by CGI . This atrium - called " turbo plaza " or " circulation lobby " in various production and behind - the - scenes materials - was intended to be located in the primary hull of the " Enterprise " in " Into Darkness " , however appears to be located in the secondary hull for its appearance in " Star Trek Beyond " . ( " Cinefex " , No . 134 , p . 72 ) The more industrial lower levels and engineering section of the ship were filmed at the Budweiser Brewery in Van Nuys , California for " Star Trek " and " Star Trek Into Darkness " . The in Livermore , California stood in for the " Enterprise " warp core in " Star Trek Into Darkness " . Though the filmmakers had explored designing sets for these sections , it was ultimately decided to film on location because they lacked the money . Production Designer Thomas E . Sanders took over Scott Chambliss ' duties on " Star Trek Beyond " , overseeing the reconstruction of the " Enterprise " interior at Vancouver Film Studios in . A departure from the previous two productions , the bridge set was built on a shaker deck , allowing three - inches of movement in all directions and negating the need to have the actors fake impacts and shakes . ( " Cinefex " , No . 148 ) To simulate the destruction of the " Enterprise " , corridor sets and the " manual release room " were constructed on gimbals , allowing these locations to roll . Other locations aboard the " Enterprise " were built with the help of digital set extensions created by Atomic Fiction , these locations included sections of engineering and the torpedo bay . ( ) The ship ' s dedication plaque lists the " Enterprise " as " Starship class " , the same as its prime universe counterpart , while the ship ' s dossier on the official movie website identifies the " Enterprise " as a " Constitution " - class heavy cruiser . The " Enterprise " is canon ically identified as a " Constitution " - class starship in a viewscreen graphic from " Star Trek Into Darkness " , seen on the main bridge of the . The website also noted that she is being " held in Beta Testing Ward 956 – approved for combat . " The maximum speed of the " Enterprise " is given as warp 8 . Construction . Co - writer Roberto Orci explained the logic of having the " Enterprise " being built on Earth rather than in space , noting that components of the ship can be built on Earth and assembled anywhere and that the " Enterprise " is not " some flimsy yacht that has to be delicately treated and assembled . " He also feels that it makes more sense to construct the ship within a natural gravity well , rather than an area that would require an artificial gravity field . Orci made these comments after a teaser trailer that was released prior to the film included footage , unseen in the movie itself , that showed the " Enterprise " under construction and being welded upon . Configuration . According to the " Enterprise " Tour and the " Starfleet Vessel Simulator " bonus feature , which was available on a Blu - ray Disc , the crew size of the " Constitution " - class was 1 , 100 . According to the two sources , the internal configuration was as follows : The primary hull housed the main bridge on the A deck , the ship ' s crew quarters were on D and E decks , F deck hosted the transporter room , and the sickbay was located on G deck . The primary hull also included the impulse drive and the science laboratories . The section was protected by phaser turrets on the ventral and dorsal sides . On the main bridge , there were fourteen seated crew positions . Several escape pods were also located in the section . The secondary hull housed the ship ' s engineering systems on N and O decks and the hangar deck , capable of housing sixteen shuttlecraft is on R deck . The secondary hull also housed the main torpedo launcher , navigational deflector , and living and work spaces for the engineers . This section was protected by phaser turrets , a forward - facing main torpedo launcher on the neck pylon , and an aft - facing torpedo launcher located on the ventral side of the hull in a recessed alcove . Several escape pods were located in this section , with a majority of them being in the neck pylon . There was a tractor beam located at the rear of the ship which assisted shuttles during landing into the hangar deck . In both sections , there were corridors and turbolifts . Corridors were equipped with communication terminals , safety features designed to keep the crew alive during emergencies , and emergency power supplies . There were access panels adjacent to doors that could restrict access to a compartment . There were passenger and freight turbolifts on the ship . The warp nacelles housed the ship ' s bussard collector s , field coils , and warp coil s . The collectors captured interstellar hydrogen via an electromagnetic field and converted the gas into fuel for the ship by a nuclear fission process . The field coils transmited subspace emissions that could be used for the sensor and communication systems . Plasma gases that were generated by the warp coils were expelled by exhaust ports located at the rear of each nacelle . Size . If the alternate reality Constitution class is the same size as it ' s prime reality counterpart , then it would mean it would be between 289 - 305 meters long depending on the configuration . Before the release of " Star Trek " on Blu - ray , there were several conflicting , early , behind - the - scenes accounts regarding the scale of the " Constitution " - class starship . Apocrypha . The " " video game shows unseen areas of the ship such as the observation lounge , officers ' quarters , and the Jefferies tube s . The video game " Star Trek D - A - C " features various named " Constitution " - class ships . According to the game , the ships could also be armed with quantum torpedo es in the late - 2250s . According to the mobile phone video game , " " , the " Enterprise " was equipped with a massively powerful phase cannon capable of slicing through and destroying multiple starships . The , a " Constitution " - class ship used as a Starfleet Academy training vessel in 2255 , is mentioned the novel " The Delta Anomaly " . According to a MSD schematic seen on of the comic " " , a typical " Constitution " - class starship had : The " Constitution " - class appears in the game " Star Trek Online " starting with the third expansion series , " Agents of Yesterday " . Obtainable in the Kelvin Timeline Lockbox , these ships are classified as the " Kelvin Timeline Heavy Command Cruiser " . According to the information on the package holding the ship , they were built in the main universe due to incursions made by the Na ' kuhl and the Sphere - Builder s , allowing them to see into alternate reality and realized that the technology of that timeline , despite a distance of just over 150 years , was similar to those in the year 2410 . The ship has a number of skins , including one that allows it to mimic the original " Constituion " - class ships . The various warp cores used in the original configuration of the " Enterprise " were reclassified as auxiliary warp cores as part of the console " Auxiliary Ejection Assembly " , which comes with the ship , allowing players to mimic the stunt Scotty does to get the " Enterprise " away from the Singularity caused by the " Jellyfish s detonation . In terms of size , the " Constitution " - class is shown to be larger than a " Galaxy " - class ( at 624 . 5 meters ) yet smaller than the ' ( at 1 , 062 meters ) which would put it closer to the ILM chart or the Blu - Ray feature numbers .
