The great size and capability of ''Galaxy''-class starships made them extremely prestigious assignments, attracting Star Fleet's best and brightest.  They were noted for their impressive abilities among Federation citizens and other [[Alpha Quadrant]] races. The ''Galaxy''-class was unique among Star Fleet vessel designs in assuming a large civilian population; many personnel brought their families aboard.

In 2365, the safety of the ''Galaxy''-class, in particular its [[warp propulsion system]], came into question when the {{USS|Yamato}} was lost in a mysterious accident near the [[Romulan Neutral Zone]].  The ship had experienced massive systems-wide failures which eventually led to a loss of [[antimatter containment]]. Further investigation by the ''Enterprise''-D revealed the malfunctions were as a result of an  [[Iconian software transmission]] and not a design flaw inherent to the ship.

Undoubtedly the most prominent early ''Galaxy''-class starship was the {{USS|Enterprise|NCC|1701-D}}, which apart from two brief periods under the command of [[William T. Riker]] and [[Edward Jellico]] was commanded for its entire nine year career by [[Captain]] [[Jean-Luc Picard]].  ''Enterprise'' made [[first contact]] with a multitude of new species, including the [[Q Continuum]], the [[Ferengi Alliance]] and the [[Borg Collective]]. Its diplomatic efforts helped cool tensions between smaller, regional powers and prevent dramatic upheavals to the security of the Federation during the [[Klingon Civil War]], and frequently checked [[Romulan Star Empire|Romulan]] and [[Cardassian Union|Cardassian]] operations in tense situations. It fought off some of the Federation's toughest foes, preventing the assimilation of [[Earth]] during the Borg invasion of 2367.

A ''Galaxy''-class ship was involved in the disastrous first contact with the [[Dominion]]. The {{USS|Odyssey}} had entered the [[Gamma Quadrant]] in order to rescue several Federation citizens who had been taken captive by the [[Jem'Hadar]].  While the ''Odyssey'' was retreating, a [[Jem'Hadar attack ship]] made a suicide run at its [[stardrive section]], causing a massive [[hull breach]] and the complete destruction of the ship. This unwarranted act led to three years of hostilities between the Federation and the Dominion, before the outbreak of the [[Dominion War]].

The ''Galaxy''-class had two hull sections, a saucer-shaped [[Hull|primary hull]] and a secondary hull which mounted the two [[warp nacelle]]s.  The hulls were capable of reversible [[saucer separation]] and were both equipped with independent flight and combat capabilities.  Generally, civilians and non-essential personnel would evacuate to the [[saucer module]], while the [[senior staff]] confronted a threat in the [[battle section]], which contained the majority of weapons systems. The saucer was even capable of crash-landing on a planetary surface.

''Galaxy''-class ships achieved warp flight through two warp nacelles, which housed multiple pairs of [[warp coil]]s.The acceleration delay between slow-reverse impulse and top warp speed, or about warp 9, was 0.300 [[millisecond]]s. The maximum speed was warp 9.6, which could be maintained for approximately twelve hours. The [[warp core]] was one of the most powerful in Star Fleet, generating approximately 12.75 billion gigawatts (12.75EW ([http://en.wikipedia.org/wiki/Watt exawatts]) / 1.275x10<sup>19</sup>W / 12,750,000,000,000,000,000W) of power. The efficiency of the warp drive could be tweaked to a point where it rivaled the new {{ShipClass|Intrepid}} ships introduced in 2370.

The ''Galaxy''-class was equipped with ten [[phaser bank]]s, located at various points along both hulls. One array was located on the [[dorsal]] of the battle section and could only be used following a separation. There were also [[bow|fore]] and [[stern|aft]] [[torpedo launcher]]s on the engineering section. Each launch tube was capable of firing at least five photon torpedoes simultaneously, each torpedo capable of being independently targeted. In the 2360s, ''Galaxy''-class ships typically carried about 250 photon torpedoes. The torpedo launchers were also capable of launching probes.  The ''Galaxy''-class was also supported a high-capacity [[deflector shield]] grid.

The [[main bridge]] of the ''Galaxy''-class was located on Deck 1 of the [[saucer section]]. As with most starships, the main bridge was modular and could be completely replaced with another bridge if the need called for it. Different ''Galaxy''-class starships had different bridge designs. The following describes the bridge design used in at least two ''Galaxy''-class starships, including the USS ''Enterprise''-D.

The forward bulkhead was dominated by the main [[viewscreen]]. Directly behind this were the [[operations manager]] and [[conn]] positions. At the very center of the room was the command area – the [[captain]]'s chair at the center, flanked by chairs for the [[first officer]] to the right, and an additional officer (typically the ship's [[counselor]] or [[chief medical officer]]) to the left. Smaller backless seats were located on the edges of the command area, for other officers to sit, should the need arise.
 
  
−
The [[tactical]] console, positioned directly behind the captain, was located in the wooden handrail that encircled the rear half of the central command area. The aft bulkhead carried several additional consoles.  These could be customized as needed and were reconfigured at least twice. In 2364, the consoles, from starboard to port, were [[science station|Science I]], Science II, [[environment station|Environment]], Emergency Manual Override, and Propulsion Systems. By [[2365]], they were Science I, Science II, [[Mission operations station|Mission Ops]], Environment, and [[engineering station|Engineering]]. The stations featured pullout seats below the console, which were normally flush with the panel below the stations.  The bridge was also equipped with two food replicators.

By necessity, the bridge had easy access to and from all other important areas of the ship. In all, there were six doors leading from the room. Moving clockwise from the main [[viewscreen]], the first door, level with, and to the right of the conn, lead directly to the [[battle bridge]] emergency [[turbolift]]. At the rear right of the [[bridge]], a shallow alcove contained two doors, one of which contained a head, the other to a corridor leading to the [[observation lounge]]. The door at the rear left of the room opened onto a standard turbolift. Continuing around, the fifth door lead into the [[captain's ready room]], the sixth to another turbolift.
 
  
−
As the main bridge housed so many critical systems, numerous emergency environmental and power backups were included so that duty personnel could continue to work for up to 72 hours in the event of a major shutdown or incapacitation of the vessel. Other safeguards included seven redundant safety interlocks to prevent the [[life support]] from being turned off on the bridge.

The bridges of ''Galaxy''-class ships were subject to several minor cosmetic changes over their first decade of service.  The first major refit came in 2371 as seen aboard the USS ''Enterprise''-D.  Six new stations were added, three on each side of the bridge replacing the equipment lockers.  The aft stations were accordingly reprogrammed and moved to different locations.  The three starboard stations were designated Science I, II, and III.  Science IV became the first aft station, followed by Mission Ops, Environment, and Engineering I/II.  The port side of the bridge had three [[communications station]]s, consoles which were not common to the bridges of 24th century ships. In addition, the command chairs were raised two steps above the helm and ops stations, to provide the captain with an unobstructed view of the forward viewscreen.  New carpeting and handrails were also added.

Located on Deck 8, it is connected to the main bridge and other vital areas of the ship by an emergency turbolift. It was designed to control the stardrive section following a saucer separation. Unlike the main bridge, there was much more focus on combat and tactical systems and no science stations. The battle bridge was modular like the main bridge; at least two variants have been seen aboard ''Galaxy''-class ships.
−
The [[observation lounge]] was located directly behind the main bridge. The room was usually used as a conference room for the vessel's senior staff. It featured large, aft-facing windows that offered a spectacular view of the back of the starship and space beyond. A conference table with seating for ten people was the main feature of the room, with [[LCARS]] screens on the port and starboard walls for information displays and retrieval. Holographic emitters embedded within the table could also be used for presenting data. Some starships featured artwork along the wall opposite the windows; when this was not present the bare wall showed several structural supports.

Engineering systems spanned twelve decks of the engineering section. [[Engineering]] itself was located on Deck 36 and was an open-plan facility, directly accessible from the corridor. Consisting of two levels, it provided direct access to the vessel's [[warp core]] and primary engineering support systems. The corridor bulkhead housed the [[Master Situation Monitor]]. Inside the main section, the [[master systems display]], affectionately known as the pool table, was the operational focus of the room. Beyond this, heading towards the warp core, the [[chief engineer]]'s office and several support consoles were located on the left, and the assistant chief engineer's console on the right. These formed part of the bulkhead protecting the main part of Engineering from the warp core. Access to the upper level, a circular area surrounding the warp core, was provided by a ladder to the left of the warp core or an elevator on the right.  The upper level had access to other warp core maintenance systems.

The Galaxy-class was a Star Fleet vessel first introduced in the late 2350s. It was the largest and one of the most powerful Federation starship classes of its time, with many serving in the Dominion War.



History

Design and development

The Galaxy-class began development in the 2350s at Utopia Planitia Fleet Yards. Numerous technologies implemented on Galaxy-class starships were tested aboard earlier prototype vessels, including the Oberth-class ship USS Pegasus in the 2350s.


The warp core was designed at Outpost Seran-T-one on stardate 40052 by some of the most brilliant engineering minds in the Federation, including Leah Brahms of the Theoretical Propulsion Group.


Major component construction of Galaxy-class ships was carried out both in orbit and at ground based facilities.

Upon its launch, the Galaxy-class became the most technologically sophisticated and complicated ship ever built by the Federation.


Early Years

The great size and capability of Galaxy-class starships made them extremely prestigious assignments, attracting Star Fleet's best and brightest. They were noted for their impressive abilities among Federation citizens and other Alpha Quadrant races. The Galaxy-class was unique among Star Fleet vessel designs in assuming a large civilian population, and so many personnel brought their families aboard.


In 2365, the safety of the Galaxy-class, in particular its warp propulsion system, came into question when the USS Yamato was lost in a mysterious accident near the Romulan Neutral Zone. The ship had experienced massive systems-wide failures which eventually led to a loss of antimatter containment. Further investigation by the Enterprise-D revealed the malfunctions were as a result of an Iconian software transmission and not a design flaw inherent to the ship.


Undoubtedly the most prominent early Galaxy-class starship was the USS Enterprise, NCC-1701-D , which apart from two brief periods under the command of William T. Riker and Edward Jellico was commanded for its entire nine year career by Captain Jean-Luc Picard. Enterprise made first contact with a multitude of new species, including the Q Continuum, the Ferengi Alliance and the Borg Collective. Its diplomatic efforts helped cool tensions between smaller, regional powers and prevent dramatic upheavals to the security of the Federation during the Klingon Civil War, and frequently checked Romulan and Cardassian operations in tense situations. It fought off some of the Federation's toughest foes, preventing the assimilation of Earth during the Borg invasion of 2367.



The USS Galaxy at the First Battle of Chin'toka

Dominion War

A Galaxy-class ship was involved in the disastrous first contact with the Dominion. The USS Odyssey had entered the Gamma Quadrant in order to rescue several Federation citizens who had been taken captive by the Jem'Hadar. While the Odyssey was retreating, a Jem'Hadar attack ship made a suicide run at its stardrive section, causing a massive hull breach and the complete destruction of the ship. This unwarranted act led to three years of hostilities between the Federation and the Dominion, before the outbreak of the Dominion War.

Galaxy-class starships saw action in many of the major fleet actions of the war, including Operation Return, where the class also played a major strategic role, grouped into Galaxy wings, the first Battle of Chin'toka, and the Battle of Cardassia.



Later status

Several more starships entered the fleet inventory during the 2370s. By the latter half of the decade, Galaxy-class ships were seen all around Federation space, from stations near Earth to near the Romulan Neutral Zone.



Technical data

Physical arrangement

Saucer separation in progress

The Galaxy-class had two hull sections: a saucer-shaped primary hull and a secondary hull which mounted the two warp nacelles. The hulls were capable of reversible saucer separation and were both equipped with independent flight and combat capabilities. Generally, civilians and non-essential personnel would evacuate to the saucer section, while the senior staff confronted a threat in the "battle section," which contained the majority of the weapons systems.


The hull of the Galaxy-class was left somewhat customizable; areas such as Deck 8 were designated as unfinished and multi-purpose, in the event that extra space was needed for a specific mission.


Command and control systems

The computer system on board the Galaxy-class was isolinear based, the most advanced circuitry of its time available to Star Fleet.
Computer systems were concentrated in a computer core, which was accessible through a maintenance room.
Each Galaxy-class vessel carried a total of three independent computer cores; two located in the saucer section and one in the engineering section.


Propulsion systems

Impulse engine (aft torpedo launcher is also visible)

Galaxy-class ships achieved warp flight through two warp nacelles, which housed multiple pairs of warp coils. The acceleration delay between slow-reverse impulse and top warp speed, or about Warp 9, was 0.300 milliseconds. The maximum speed was warp 9.6, which could be maintained for approximately twelve hours. The warp core was one of the most powerful in Star Fleet, generating approximately 12.75 billion gigawatts of power. The efficiency of the warp drive could be adjusted to a point where it rivaled the new Intrepid-class ships introduced in 2370.


The warp core itself spanned twelve decks in the engineering hull. The deuterium tanks were above the core, while antimatter storage pods surrounded the base of the core on Deck 42.


There were three impulse engines, two on the saucer section and one in the stardrive section. In early models, only the impulse engine in the stardrive section was usually active.

  • Upgrades to the propulsion systems were tested in 2370 aboard the Enterprise-D. This ship received a new warp core manufactured with interphase technology. A major rehab of the nacelles was also conducted that year. By the mid 2370s, most Galaxy-class ships began operating with all three impulse engines activated.


Scientific systems

Galaxy-class ships supported a wide variety of scientific equipment and laboratories studying many different disciplines. The departments often had to compete for limited resources such as sensor time, which were allocated by the operations manager or, on occasion, the executive officer.

  • Upgrades: Sensor systems could be customized and upgraded as necessary for a specific mission. Additional equipment could be added as required. The latest technologies were generally outfitted to Galaxy-class ships as they left the experimental stages.


Tactical systems

The Galaxy-class was equipped with ten phaser banks, located at various points along both hulls. One array was located on the top of the battle section and could only be used following a separation. There were also torpedo launchers on either side of the engineering section. Each launch tube was capable of firing at least five photon torpedoes simultaneously, each torpedo capable of being independently targeted. In the 2360s, Galaxy-class ships typically carried about 250 photon torpedoes. The torpedo launchers were also capable of launching probes. The Galaxy-class was also supported a high-capacity deflector shield grid.

  • Upgrades: The Enterprise-D received a weapons systems upgrades in 2370, including a load of higher-yield photon torpedoes and enhanced targeting sensors programmed by Lieutenant Worf. Certain Galaxy-class ships were refit with additional phaser strips on the top surfaces of their nacelles by 2372.


Crew support

While Star Fleet policy permitted the immediate family of officers and crew to stay aboard starships prior to the advent of the Galaxy-class, it was the first class specifically tailored to accommodate civilian as well as Star Fleet personel. Civilians were allowed to hold varying positions in the sciences division aboard the Galaxy-class.


Interior design

A typical saucer section corridor

With the presence of families and non-Star Fleet personnel aboard, the Galaxy-class interior was mostly designed for their comfort and the well being of the crew in general. While the major command sections maintained form and functionality above all, there remained a much more "relaxed" feel about the design of many of these areas.

Main Bridge

A corridor in the engineering section
The ops and conn consoles

The main bridge of the Galaxy-class was located on Deck 1 of the saucer section. As with most starships, the main bridge was modular and could be completely replaced with another bridge if the need called for it.
Different Galaxy-class starships had slightly different bridge designs.


The forward bulkhead was usually dominated by the main viewscreen. Directly behind this screen were the operations manager and conn positions. At the very center of the room was the command area – the captain's chair at the center, flanked by chairs for the first officer to the right, and an additional officer to the left. Smaller backless seats could be located on the edges of the command area, for other officers to sit, should the need arise.


By necessity, the Bridge had easy access to and from all other important areas of the ship. In all, there were six doors leading from the room. They led to rooms or corridors such as a bathroom, the observation lounge, a standard turbolift, and the Captain's Ready Room. As the main bridge housed so many critical systems, numerous emergency environmental and power backups were included so that duty personnel could continue to work for up to 72 hours in the event of a major shutdown or incapacitation of the vessel. Other safeguards included seven redundant safety interlocks to prevent the life support from being turned off on the bridge.


Battle Bridge

Located on Deck 8, it is connected to the main bridge and other vital areas of the ship by an emergency turbolift. It was designed to control the stardrive section following a saucer separation. Unlike the main bridge, there was much more focus on combat and tactical systems and no science stations. The battle bridge was modular like the main bridge; at least two variants have been seen aboard Galaxy-class ships.


Observation Lounge

Usually located directly behind the main bridge. The room was usually used as a conference room for the vessel's senior staff. A conference table with seating for ten people was the main feature of the room, with LCARS screens on the port and starboard walls for information displays and retrieval. Holographic emitters embedded within the table could also be used for presenting data.


Main Engineering

The "pool table" and the MSD

Located on Deck 36, it is an open-plan facility, directly accessible from the corridor, and spans 12 decks. Consisting of two levels, Main Engineering provided direct access to the vessel's warp core and primary engineering support systems. Towards the warp core, the chief engineer's office and several support consoles were located on the left, and the assistant chief engineer's console on the right. These formed part of the bulkhead protecting the main part of Engineering from the warp core. Access to the upper level, a circular area surrounding the warp core, was provided by a ladder to the left of the warp core or an elevator on the right. The upper level had access to other warp core maintenance systems. Engineering could also serve as a backup to the main bridge if it was damaged or disabled.


In the event of a major failure, such as an imminent warp core breach, engineering was equipped with isolation doors and forcefields to contain various sections of the facility.


Medical Facilties

The Galaxy-class medical department was charged with providing health care to the ship's company and all attached personnel, and possessed equipment to treat a variety of species.

  • Sickbay: There were at least three sickbay wards aboard the ship, with at least one in the saucer section and another in the stardrive section. Equipment storage and various control panels were located throughout sickbay. The Chief Medical Officer's office was just off of the main sickbay. Separate, private recovery rooms were also located near sickbay, as was a nursery and a diagnostic center.
  • Medlabs: Galaxy-class ships had at least four medical laboratories of varying sizes. Other larger medlabs similar to standard science labs were elsewhere.
  • Surgical Suite: Surgeries too complicated for the sickbay ward could be conducted in a separate surgical area which had a large variety of bio support systems.
  • Emergency Biological Support Unit: This was a separate room located near the main sickbay facility on Deck 12. Patients with severe burn injuries could be treated here in a closed cell.
  • Morgue: A morgue facility with storage slots for several bodies was located adjacent to sickbay.
  • Counselor's Office: The ship's counselor had his or her own office, located on Deck 9. Crew members needing emotional support could meet in privacy with the counselor here.


Scientific Department

The Galaxy-class starship housed over one-hundred separate scientific research labs. Very few of the research labs remained under the same discipline of science for more than six months. Most shared the same design; only a few had extremely specialized equipment.

  • Stellar Cartography: Located on Deck 9, with at least two laboratories: a smaller facility similar to the other labs aboard the ship; another, a much larger cylindrical room spanning three decks. The walls of the room were designed to be a three-dimensional display.
Cybernetics lab
  • Cybernetics Lab: A circular room with a raised platform in its center, containing a shell which could hold a cybernetic body. The entire assembly could retract into the ceiling and was directly controlled by a console to the side. There were additional wall-mounted consoles throughout the room. On the Enterprise-D, the laboratory was redesigned in 2368 to become much more rectangular, although it still featured the shell assembly.
  • Arboretum: Capable of studying and supporting a wide variety of plant life.
  • Cetacean Labs: Some Galaxy-class starships carried a complement of cetaceans. Among the crew, these facilities were also known as "the dolphin tanks" or the "aquatic lab."


Transport and Cargo

Transporter room
  • Transporter Rooms: Galaxy-class starships had twenty transporter rooms located throughout the vessel.
    Four transporter rooms were located on Deck 6 of the saucer section, while two more were on Deck 14 of the stardrive section.
  • Cargo Bays: There were numerous multi-level cargo bays located all throughout the ship. Most of these bays contained sufficient room for storage, cargo transporters, and anti-grav units for the transportation of cargo. Cargo bay four was the only cargo bay with direct access to the exterior hull.
  • Shuttlebays: There were three shuttlebays aboard each Galaxy-class starship, supporting many varieties of shuttlecraft.
    The main shuttlebay was located on Deck 4 in the saucer section. Two smaller shuttlebays were on Deck 13 of the engineering hull.


Crew Quarters

Mostly located in the ship's saucer section in order to provide safety for civilian and non-essential personnel during a saucer separation. The engineering hull also contained crew quarters, generally containing engineering personnel and their families. Pets, including cats and dogs, were also allowed aboard a Galaxy-class ship.

There were several types of crew quarters aboard:

  • Junior Officers' Quarters: These small quarters units were located on the interior of the ship and lack windows. They were comprised of a living area, a bedroom, and a bathroom.
    Crewmembers of Lieutenant Junior Grade were given their own quarters; ensigns were required to share quarters. The living area contained a replicator terminal.
  • Officers' Quarters: These quarters lined the edge of the saucer section and contained a living area, a bedroom, and a bathroom area. They were generally reserved for lieutenant commanders and above.
    Similar quarters were also available to enlisted and civilian personnel with families.
  • Captain's Quarters: The captain's quarters, located on Deck 8, were similar to the officers' quarters but were slightly larger. The Captain had a large desk area and work terminal.
    VIP and diplomatic guest quarters shared the same layout.


Recreational Facilities

  • Ten Forward: Located at the forward-most section of the saucer module on Deck 10, Ten Forward served as the social center of a Galaxy-class ship. It had a variety of recreational games, as well as a fully stocked bar. The replicators were also able to produce other food and drinks for the crew to enjoy in a relaxed social setting. Its large, panoramic windows permitted a view of the ship's passage through space.
  • Holodeck(s): The Galaxy-class carried sixteen holodecks, which are located on Decks 9, 10 and 11.
  • Phaser Range: Located on Deck 12. To practice, a person stood on a platform in the center of the room, illuminated only by the light which came from above the platform. Colored circular lights whirled across the walls. After completing a round, the number of hits and misses, along with the percentage of accuracy, were tallied by the ship's computer. There were at least fifteen levels of difficulty, and the range could be customized for two-player competition. The phaser range was also used by security officers to train personnel in marksmanship.
  • Gymnasium: Located on Deck 12, it contains a variety of recreational equipment for a variety of sports, such as aerobic studios, martial arts areas, and a squash court.
  • Theater and Concert Hall: There was a large theater aboard most Galaxy-classes, which was equipped to seat large groups of people.
    The theater could also be used as a concert hall for musical performances by crew members.
  • Salon / Barber: The salon was an area where crewmembers could get personal care ranging from a simple haircut to an elaborate spa-like treatment.
  • Replimat: A place where crewmembers could replicate items too large or complicated for a standard food replicator terminal. They could "shop" for certain items by reviewing the ship's database.
  • Educational Facilities: There were several small schools of varying sizes located throughout the ship, ranging from actual classrooms to specialized workshops.
