The Galaxy class is a technologically advanced type of starship utilised by Starfleet during the 24th and 25th centuries.

It was one of the largest and most powerful Federation starship classes of its time with its primary roles being heavy cruisers in defense and military situations, exploration, and diplomacy.


Technical data[]




The warp drive worked by generating subspace fields to form a bubble of selective space-time displacement that enveloped the exterior of the starship, distorting the local spacetime continuum and allowing it to "ride" on said distortion at velocities that could greatly exceed the speed of light as determined by the theory of relativity. The bubble carries the ship along with it. This also had the physical effect of reducing the inertial mass of any object encompassed by the warp field.

Because the ship isn't moving relative to spacetime in its own frame of reference (the inside of the bubble), the light-speed limit as determined by the law of relativity doesn't apply. Nevertheless, the speed of the drive was measured in "factors" with the maximum sustainable speed being factor 9.6 which is 2,017.93 times the speed of light and 0.23 light-years/per 1 hour. The cruising speed is factor 4 which is 101.59 times the speed of light or 0.28 light-years/per 24 hours. Emergency velocity, sustainable for 16 hours, was factor 9.8 which is 2,450.01 times the speed of light and 0.28 light years/per 1 hour or 4.47 light years/16 hours.





Crew support systems[]



  • Tractor beam: The class also features multiple tractor beam emitters: at least four, which project an attenuated beam of gravity with a rated output of 450 milli-cochranes toward a target thus allowing the manipulation of said object's trajectory, either to attract or repel.

Weapon systems[]


Galaxy class ships possess 3 dorsal strip-style emitter segments on the primary hull - 1 primary dorsal segment extending 340° and 2 P.D segments to either side of shuttlebay one. The arrays cover the entire semi-sphere above the ship, except for a few blind spots close to the hull and Shuttlebay. Furthermore, there is 1 ventral phaser array on the primary hull, extending 320°. Total of 4 arrays.

On the secondary hull, there are 2 dorsal arrays - both are P.D and placed in the far aft of the ship. Then there is 3 ventral phaser arrays - two P.D. Total of 5 phaser emitter arrays on the secondary hull. On each vertical bound nacelle pylon, there is a lateral phaser array with 190° coverage. Overall, ships of this class boast an impressive phaser arsenal with eleven known array segments.

Each segment is of the type-X variety and fires a coherently pulsed orange-red beam of directed rapid-nadion particle discharge at a target with a maximum effective tactical range of 300,000 kilometres. Each phaser array takes its energy directly from the impulse drive and auxiliary fusion generators but power can be diverted directly from the warp core providing a major boost though the capacitors cannot withstand the excess energy for long. Individually, each type-X emitter can discharge approximately 5.1 megawatts per second of sustained barrage. However, with warp power, the maximum output can be increased to 50 MW (10x the standard output).


Secondly, these ships are also equipped with fore and aft torpedo launchers: 3 on the saucer section (forward facing) and 2 on the engineering section (rear facing). Each launch tube was capable of firing at least five torpedoes in a single salvo with each torpedo being able to be independently targeted.

The Galaxy class featured entirely unique torpedo targeting subsystems making them considerably more accurate when compared to other starship classes, especially at long-range distances. Maximum effective tactical range is 3 million kilometres. The complement carried onboard these ships is 275 high-yield photon torpedoes which has a matter/antimatter reaction based warhead.


Additionally, these vessels possess a stockpile of 165,000 ready-made mines in storage. Each mine possesses multi-adaptive refractive shielding that disguises it from conventional sensors making them, when deployed, practically invisible while still abiding by the various anti-cloak treaties the Federation has signed.

The mines are equipped with a self-maintaining replicator unit, such as that every mine that was detonated or deactivated would be immediately replaced by its neighbor. Each mine only has initially 1/65 of the material stored in themselves for a single replacement mine. Onboard replicators however transfer material from one to another where it is needed in the field through networked miniature transporters. As stored material begins to run out the mines have a zero-point extraction system for matter replenishment.

The exterior shells of the mines are refurbished duranium cargo containers and has proximity as well as contact sensors for detonation with a neutrino source counter for distance keeping with one another, a thruster system of a class-1 probe with a single fuel source designed for station keeping.

These mines were designed to emit verteron pulses to simply disable subspace systems on passing starships causing fluctuations in their warp coils and warp drive as well as neutralising communication systems before swarm-detonating their tricobalt warhead delivering a series of thermokinetic explosions.

Defensive systems[]


Vessels of this class boast an impressive, yet somewhat outdated deflector shield grid when compared to the newer Curiosity or Sovereign classes. There are a total of six reinforced shield emitters on the external port, starboard, aft, fore, middle ventral and dorsal middle sides of the Galaxy class and each one generates a standard output of 625 megawatts, resulting in a total field strength of 3,750 MW, however, the typical shield configuration is 3 or 4 emitters with a strength of 1,875-2,500 MW. The power for the shields is taken directly from the warp engines and impulse fusion generators.

When raised, they maintain an average range of 30 meters away from the hull and project a multi-layered translucent bubble-like screen comprised of energetic EM distortion containing a high concentration of graviton particles. Multi-phase graviton polarity flux technology incorporated into the shields allows it to better deal with more powerful and sophisticated weaponry including that of the Dominion's phased polaron weapons, Breen energy dampeners, and Borg systems.

Energy generation[]

Ships of this class are powered by a antimatter x matter warp core which generated enormous quantities of electricity through controlled explosive collisions releasing pure light (energy) which is then harnessed directly into FTL as well as several other major systems. This is specifically accomplished via the annihilation of equal parts matter and antimatter using a combination of deuterium (a hydrogen atom containing a proton and a neutron in its nucleus) and anti-deuterium (essentially a deuterium atom, whose atomic properties are exactly reversed from those of a normal deuterium atom). It is regulated through a matrix of magnets and Dilithium which uses a recrystallization process in the form of a theta-matrix compositor to extend the structural integrity by injecting high-energy photons and gamma radiation. It has a maximum rated power output of 1.65 kilocochranes or 12.75 billion gigawatts (12.75 exawatts).

It uses a Transkinetic chamber and Radiometric converters, among other things: The residual anti-matter from the warp core is then processed in the transkinetic chamber, where it's broken down on the subatomic level. The theta radiation is absorbed by a series of radiometric converters allowing the recycling of energy in order to use it to power the majority of systems ranging from life support to replicators and illumination while also eliminating all waste making it virtually 100% efficient.

Furthermore, these vessels also utilise a series of impulse cores comprised of a network of multiple spherical fusion reactors that are fueled by Deuterium and make use of a nuclear fusion process to generate energised plasma that is then distributed along a plasma conduit managed EPS grid. These powered the impulse drive as well as several other major systems and could also be routed to shields or weapons for a boost.


The Galaxy class design included two hull sections: a saucer-shaped primary hull, and a detachable secondary hull which housed the ship's primary engines. It weighed 4.96 million metric tons and was 641 meters in length (2,s103 feet), 470 meters wide (1,541 feet), and 147 meters tall with each deck (42 total) spanning 3.5 meters. It could comfortably support 1-6 thousand humanoids under an M-Class atmosphere with its maximum life support capacity being 15,000.

Saucer separation[]

On the Galaxy class, saucer separation was primarily used as a way for the civilian passengers and nonessential crew complement to escape in the saucer section, while the senior staff and essential personnel engaged a threat or entered a potentially dangerous situation in the stardrive section.

It was designed to function for extended periods as two separate vehicles with their saucer-separation capability, meaning that both the primary and secondary hulls have sufficient power generation, life support, defensive, small craft, crew support, and scientific abilities to be truly independent.

Starship section design[]

With the presence of families and civilian 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 when compared to other Federation vessels.


Starships of the Galaxy class featured wide and comfortable corridors similar in arrangement to starships of the much earlier Constitution class: concentric corridors echoed the shape of the primary hull and were interconnected with radial corridors.

The predominant color scheme of the corridors aboard possessed navy blue carpeting on the floors and non-reflective silver/gold wall paneling.

At specific junction points, there are emitters to create cadderon force fields of varying intensity. The computer could be programmed to run a series of force field activations and deactivations within the ship, effectively creating a protected corridor which could follow a person or to isolate individuals within a specific section.

Main bridge[]

The main bridge of these vessels 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.

The forward bulkhead was usually dominated by the main holographic viewscreen. Directly facing this screen were the operations manager and navigation/helm station. There were also a engineering relay station, tactical, science I and II, and a communication station. At the 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.

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. In emergency situations, these doors are closed off by isolation bulkheads made from Tetraburnium reinforced Duranium that had a multi-phasic alternating current flowing through it. The current prevented shapeshifters from shifting through and also blocked out transporter signals while the tetraburnium reinforced against extreme heat and pressure and the Duranium was for density + general durability.

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 boasting no science stations. It was darkly lit and much more cramped.

Observation lounge[]

Located directly behind the main bridge, the room was usually used as a conference room for the vessel's senior staff ie: captain, first officer, chief medical officer, chief engineer, chief of security, chief operations officer, and chief science officer. A dark-brown hexagonal conference table with seating for at least ten people was the main feature of the room, with LCARS screens on both ends of the rooms walls for information displays and retrieval. Holographic emitters embedded within the table could also be used for presenting data which was physically interactable. The observation lounge was decorated by self contained hydration pods with plants inside, and had two replicator terminals.

Main engineering[]

Located on Deck 36, it is an open-plan facility, directly accessible from the corridor, and spans numerous decks. Consisting of two primary levels, main engineering provided direct access to the vessel's cylindrical 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. Access to the upper level, a circular area surrounding the warp core, was provided by a open turbolift to the left of the warp core or a ladder 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. The operational focus point of the primary area as soon as one walked into main engineering was the master systems display table commonly referred to as the "pool table".

In the event of a major failure, such as an imminent warp core breach, engineering was equipped with isolation doors identical to the ones on the bridge and level 10 force field emitters to contain various sections of the facility, usually to seal off the warp core prior to detonation or ejection.

Medical facilities[]

The Galaxy class medical department was charged with providing health care to the ship's entire complement and all attached personnel, and possessed equipment to treat a variety of species - over 100.

There are 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 and featured two viewports overlooking primary patient care but had a privacy opaque mode installed in the glass, the bulkhead was magnetically locked and was hermetically sealed, it was furnished with one white 2 seater sofa, a small rectangular table, a chair facing the sofa, a replicator terminal behind the CMO's desk, self contained hydration pods with plants inside, and at the back of the room was a desk with a angle-adjustable computer monitor installed in it.

Primary sickbays consist of a large room with at least 4 biobeds placed adjacent to one another divided by holographic drape, as well as a host of other medical based technology and computer stations including monitors installed in the walls. Biobeds are equipped with isotropic restraints that hold down patients with increasing levels of intensity to reduce movement. There is panoramic view ports overlooking space and sickbay has advanced holographic emitter matrices capable of generating Mark IV EMH's (Emergency Medical Hologram). Each Biobed is outfitted with a metabolic suspension device, medical sensors for monitoring the current state of the patient and providing real-time updates down to the cellular level, and there were also specialised biobeds such as "surgical biobeds" which possessed built in laser scalpel claws, could control or increase metabolic support, a replicator-based regenerator which is far superior to the hand-held dermal regenerators as it could regrow limbs, organs, and tissue on a living organism instead of merely prompting new skin cells to grow.

There is separate, private recovery rooms near the main sickbay, as was a nursery and a psychiatric center where the ship's counselors generally reside. There was also a null-G ward for providing relief to Elaysian crew members with an optional treatment of neuromuscular adaptation.

Additionally, there was a space for physical rehabilitation of patients with several weights available in racks as well various scanners, including the prominently placed unit located in the center of the ceiling that measures muscle mass to fat ratio and electrolyte readings amongst a variety of other things.

Scientific department[]

Starships of this type 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.

Basic and standard configuration of science Lab has three different tables, the center one being the largest and boasts a Replicator terminal. Computers and monitors flank the sides of the room. All Labs come stocked with scientific equipment, such as Tricorders, specimen containers, neutron microscopes that use a stream of neutrons to view subjects at the atomic level, and etc.

There were cybernetics labs, astrophysics lab, stellar cartography lab, planetary sciences labs, geological labs, engineering research and development labs, engineering test bays, quantum mechanics labs, exobiology labs, hydroponics laboratory, cultural anthropology, and et cetera.


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. It was so massive that an explosive decompression of the air within the bay would contain enough force to propel the ship forward. Two smaller bays, shuttlebays 2 and 3, were on Deck 13 in the engineering hull.

Furthermore, they were equipped with five hangars - hangars 1, 2, 3, 4, and 5, for the overhauling, refitting, testing, and storage of auxiliary craft.

Force-field technology allowed shuttlebay space doors to usually be kept closed, and when these were opened during shuttlebay operations, the physical doors were replaced with a stable EM gravitic field where shuttlecraft or other space vehicles were about to board or were about to be launched. These force-fields could be penetrated by the shuttlecraft itself, while nonetheless preventing decompression through exposure to the vacuum of space of the shuttlebay.


Each quarters has a doorbell, a light pulsing sound. When the occupants were not in their quarters, it automatically locked magnetically. It was considered very rude to enter a room without ringing the bell first, however, individuals of sufficient clearance could unlock the doors.

Quest quarters[]

A living space assigned to a temporary resident of a Galaxy class starship. Standard guest quarters are not the largest quarters available, technically the smallest unless compared to lower level crew quarters.

Typically, quest quarters consist of a modular room (slightly long square shaped or a short rectangle) featuring a bed, a replicator terminal, storage space, and a computer monitor built into the wall.

Crew quarters[]

The majority of the enlisted crew and junior officers shared quarters and bunk areas. Specifically, for junior officers such as cadets and ensigns as well as non-ranked civilian crew were accommodated in residential hallways located within the saucer section. Residential hallways consisted of barracks-style bunk bed slots built into the walls. Each individual compartment included their personal effects, a computer terminal screen, and small storage for uniforms. Officers assigned residential hallway bunks used communal sonic showers. Additionally, each compartment had a holographic screen for privacy while sleeping.

On starships such as the Galaxy class, crew members ranked lieutenant junior grade or higher were given their own quarters while personnel like ensigns were required to share quarters. Lieutenant junior grade+ quarters consist of a private room equipped with a replicator terminal, a small bookshelf built into the port wall, a bed, usually a window facing space, and a small table as well as a small bathroom with a sonic shower. Ensign level quarters are double occupant and as such has two beds, storage space, two workspace desk areas, and computer terminals.

Officer's quarters[]

It also featured separate quarters for higher-ranked officers. Rank was not a deciding component of these quarters but rather what ones position is in the ship. For example, if one held a critical job title such as CMO, CEO, CSO, or etc, they are automatically assigned such rooms regardless of what official rank they may have.

This type of quarters featured a more condo-style layout.

It was two levels, separated by a twisting staircase. The bottom level consisted of a sofa and table area and a small modern kitchen section toward the right end which has a replicator terminal and space for actual food storage/preparation as well as a thin rectangular shaped and horizontally positioned breakfast bar island with 4 stool-style chairs. Furthermore, there is a metallic table with enough space to seat 6 individuals. The walls are wood-paneled and the floor features gray carpeting. The upper level consists of a open floor plan with only a bed at the end with a chaise lounge chair less than two metres away from the bed. This level is dimly lit with only two orb-style lights at each side of the bed on mini-tables. Furthermore, the upper level also has view ports to the outside and has a comprehensive holographic system allowing for the entire room to function like a limited holosuite. Senior officer quarters also possess a bathroom equipped with a sonic shower.

VIP and Captain's quarters[]

Each Galaxy class starship boasts a number of VIP staterooms, reserved for special guests such as ambassadors, visiting captains or Admirals. The accommodations of the ship's commanding officer were identical to these staterooms with it instead being referred to as the "captain's cabin".

These rooms featured the same holographic systems as the senior officers quarters and had a large desk area and work terminal as well as separate living and sleeping areas though was only one floor but with an open floor plan. It has replicator terminals, sofas, and a large table as well as private bathroom featuring both a water-based and sonic-based showers.


The brig is a special containment room designed to detain individuals on a Galaxy class vessel. It is built to detain multiple people within a cell though typically it was one occupant per cell and the cells themselves tend to be small with a simple boxed-shape and three sleeping compartments built into each wall with the 4th wall being open to the outside security office but sealed off using a forcefield. The brig's force field, also called a "smart" security barrier, is designed to automatically adjust to any force exerted against it, thus preventing an escape. The force field could also be made to open just a small gap, wide enough for food to be passed to the prisoner.

There are at least ten alcoves each with room to comfortably fit 3 humanoids for a total known capacity of thirty at any given time but can hold more. Furthermore, it also included facilities such as a flip out sink hidden behind a panel and toilet that extends out of the ground plating.


  • Galaxy class ships have a go anywhere, do anything design ethic that makes them suitable for games of all sorts, ranging from exploring entirely alone for years to heading up a task group.
  • The equipment of mines carried onboard Galaxy class ships is a controversial action in Starfleet Command and one not widely publicised.
