OVERVIEW:
The Galaxy Class starship entered service in 2353 marking the crowning achievement of almost seventy-five years of engineering advancements starting with the Transwarp Development Project in the late 22nd century. With two variants in service, the Galaxy Class has serviced the Federation and Starfleet even though some were incomplete. Galaxy Class vessels are the largest in the fleet, built to boast Starfleet's most advanced technology and show the Federation's presence as if a core member world was next door.

Initial production of the Galaxy Class began at the Advanced Starship Design Bureau Integration Facility, Utopia Planitia, Mars, and has since expanded to include other classified bases where nearly two of these vessels enter service each year. The first of the variants were assembled and launched from the Advanced Starship Design Bureau Integration Facility, Utopia Planitia, Mars starting in 2369 before being consolidated with the rest of the primary production facilities on Earth, namely McKinley Station by 2370.

The design of primary and secondary hulls has been a staple of Starfleet since it's inception over two hundred years ago. Advances in that design includes the emergency separation mode. Where the primary and secondary hull split into two separate vehicles each capable of individual flight maneuvers. However this design was an emergency response only, which required the ship to be towed to a Starbase to be put back together. However the Galaxy Class, unlike the Excelsior and Ambassador Classes, can perform a saucer separation and rejoin itself, one of the biggest advances since the procedure was conceived. This advance in saucer separation makes it possible for the Galaxy Class to use the maneuver more often as a tactical maneuver, instead of a strategic contingency.

The Galaxy Class is well armed. Describing it as the best-armed ship in Starfleet could lead to arguments, but the vessel has always been able to hold it's own, even in some mismatched battles. Being the first vessel to mount the Type-X Phaser Array has made the class a foe to contend with. However, at the time of it's design, Starfleet decided that it would be best to limit the amount of torpedo tubes aboard the vessels. Designers went with five, in the original specs. After layout problems and Starfleet's recommendation for less, the designers went back to the drawing boards. They decided to use a larger launching system, one that would be able to process a loadout of ten casings. There were two of these launchers placed into the plans (plus an extra launcher for the separated saucer); Starfleet approved. Since that time, designs of other classes have had increasingly more amounts of torpedo launchers and tubes placed on them. This to counter the new and increasingly more powerful threats facing Starfleet.

Even though the Galaxy Class is a relatively young class of Starship, Starfleet and the Advanced Starship Design Bureau were forced to devise three variants on the Galaxy space frame. These variants are the two Galaxy-Uprated versions and Galaxy-Incomplete, each making changes to the spaceframe because of unforeseen threats. The first upgrade came with the third batch of vessels that came off the production line. These vessels had been built only to the point of spaceframe completion during the time of the original production. They were then stored away for a short time. When production started on them again in the mid 2360's to late 2360's, two extra phaser arrays were added to the nacelle housings. These upgrades also included advancements to the warp core. The upgrade made the ship faster and more efficient allowing it to achieve Warp 9.9 for twelve hours. In 2370, the Enterprise-D, had the propulsion upgrade performed (the phaser upgrade could not be performed do to over complicated structural reworking). Only a few weeks later this vessel discovered that Warp Drive causes instability between the barrier of Space and Subspace. Along with this discovery came it's limitation of Warp 5, with that the implementation of the upgrade to existing vessels was halted. It wasn't until three years later that a solution started to trickle down from the Advanced Starship Design Bureau. This version of the propulsion upgrade solved the Warp Pollution problem and was implement fleet wide, not only on Galaxy Class vessels.

The second upgrade revolves around a weak spot on the Galaxy Class. During first contact with the Dominion the USS Odyssey was destroyed revealing this weakness. Around the deflector dish and neck of the Galaxy Class is an extreme weakness to attack. Even though a suicidal enemy vessel attacked the USS Odyssey, this weakness was later proved to be serious under torpedo fire. Only two vessels received the solution to this situation before the war started. It was a hull upgrade of ablative armor around sensitive areas. When the war started, Starfleet ordered that the Galaxy Class vessels currently on the production line be rushed, with 68% of the hull's empty. Most of these vessels did not have the phaser upgrade, given to the third batch of vessels, owing to the fact that there was more nacelle housings available without them. They did however receive the upgraded propulsion system and hull armor.

The Galaxy-Uprated Class without the phaser upgrade is by far the most numerous of the Galaxy Class vessels built to date. Starfleet does not plan on giving them the phaser upgrade any time in the near future because the structural reworking still remains over complicated. The second most numerous version is the Galaxy-Incomplete Class. These vessels are currently being recalled as time permits. With sixty-eight percent of the hull missing, it takes as long as building a new Galaxy Class starship to finish off the hull without damaging the existing systems. The last version, with currently five ships total, is the Galaxy-Uprated Class with the phaser upgrade. This version of the class is the current production run. The original version of the Galaxy Class saw its last days of service around 2373, matching the prediction of twenty years.

Long before 2343, when the Galaxy Class officially began, the seeds were being planted. During the waning days of the failed Transwarp Development Project in the late 2280's, the scope of advances in Warp Field Theory were beginning to be realized. While some arrogant designers, desperate to salvage the Transwarp Drive, thought they could modify the Excelsior Class enough to make their drive work, others knew it would be decades before the advances in theory could even be applied in practice. Starfleet not recognizing the split, went ahead with the refit of the Excelsior in the 2290's, and only afterwards came to the realization that the Transwarp Project had failed.

By 2310's, those that had left the Transwarp Project and their inheritors were ready to pursue the next great project. They had designed the Ambassador Class; the ship they had hoped would make their dream come true. The Ambassador Class was designed to be extremely large. So large that it came with a new set of problems, especially with the Impulse Engines. These were later solved with the addition of the Space-Time Driver Coil. However, the dream that was sparked almost a half century before was not realized. It had been glimpsed though, and Starfleet was convinced into backing it.

HISTORY:
The Ambassador was not what the designers had their highest hopes for, but from the start of that project they realized the chances were small. But Starfleet couldn't wait another seventy plus years (even though they did have to wait another thirty years before the fruits of their labor came about). Wanting to fast track the project even more they divided the project into several parts. The first step was testing the structure of the new engine. To facilitate this as fast as possible the designers went to the extreme of salvaging old parts to mount the nacelle on. This part of the project was dubbed the Freedom Class. The salvaged parts were the primary section and the "neck" of a Constitution-Refit Class with one nacelle structure graphed onto the ventral portion of the "neck." The single nacelle allowed for expedient testing, and cut back on material costs. The design was never put into production, and only a few were ever manufactured for testing. They existed in service for five years and were then moth balled after all the necessary data of nacelle design had been gathered. During extreme emergencies the existing vessels were taken out of storage and put into use. Notable occurrences were the first Borg Incursion and the Dominion War.

The next tests needed to focus on the actual engine of the future starship. This portion of the project was called the Niagara Class. Based off of Ambassador Class spaceframes that failed inspection, the Niagara Class had three nacelles. It was a weak design, but never intended to make it to production. The few designs that were made used the three nacelles to power up to the strongest warp field the design could handle. Had it not been for the third nacelle the power level would never have been reached, and again Starfleet did not want to wait. The designers also decided that the Niagara Class could be used for subspace geometry tests. By the end of the 2320's all the tests on this class were completed and the ships were sent to storage facilities. One ship was brought out in an attempt to counter the Borg threat at Wolf 359 in 2367.

By the early 2330's the designers were ready for something bigger. They went for completely original classes. The tests on the Niagara Class proved one thing, the more organic the ship was in shape the better it made the transition into warp. So the design of the Springfield Class would reflect this, with more curves. This positioned the Springfield Class as the first vessel with a similar design to the future vessel, as yet still unnamed even in discussion. The Springfield's design incorporated an elliptical saucer and angled secondary hull. The ship tested the end result of organic-like designs as well as advances in warp drive technology. It was limited in production, unlike its testbed predecessors, which never made it into production at all.

The next class was the Challenger Class. It was slightly similar in design to the Springfield, but had a larger saucer and almost no secondary hull. Its nacelle structure was also similar to the designs original tested on the Freedom and Niagara Classes. The Challenger also saw limited production, like the Springfield.

The Cheyenne Class was the last in the three designs. It was similar in size and shape to the Springfield Class but had four nacelles. These nacelles, when powered up at the same time, allowed the designers to test what they estimated the full strength of the future starship to be. These tests provided the most substantial and what eventually proved to be accurate data that the testbed vessels would bring. The Cheyenne Class became a full production vessel until the 2350's.

Now it was time for the next generation to start. The designers had gathered all the data they needed before they could begin on the final designs. The first vessel would be the New Orleans Class. It was the middle of the 2330's when work started. The New Orleans would be the first to test the eventual shape of the future vessel, still unnamed by Starfleet mandate to the dismay of the designers. Most of the designers had the feel of the scale for the future vessel though, and the New Orleans was appropriately measured to that ideal. This vessel became very popular and was in full production until the 2360's.

By the late 2330's designers were ready to jump into something that had much larger proportions. The Nebula Class came into being, designed as a production line vessel. It was a full-blown version of the future vessel, which the designers had dubbed the Galaxy Class, however Starfleet was still not ready to give it a name. With just one vessel the designers knew they could begin work on their ship.

It had been over eighty years in the making. Two generations of starship designers had toiled; most of the first group was gone. Most had died, and those who remained were either too old or still held on too tightly to the idea of a Transwarp Drive. But in 2343 Starfleet had given the word, and the designers were ready to create the pinnacle of almost one hundred fifty years of work tracing it's routes directly back to the Constitution Class. When Starfleet gave the project it's official name they conceded to the designer's wishes and it was the Galaxy Class. In 2344 and 2345 the Advanced Starship Design Bureau started working on the design of the vessel. By 2349 all the ship's systems were frozen and they were ready to build.

Construction on the first batch of vessels, the USS Galaxy, USS Yamato, and USS Enterprise-D, were started in 2350. By 2363 all three had been launched. The second batch of vessels was built based on the lessons learned from the first three. After these ships were made more spaceframes were built, partially deconstructed and sent to top secret locations.

Even though the Galaxy Class was a relatively young class of starship, Starfleet and the Advanced Starship Design Bureau were forced to devise three variants on the Galaxy space frame. These variants were the two Galaxy-Uprated versions and Galaxy-Incomplete, each making changes to the spaceframe because of unforeseen threats. The first upgrade came with the third batch of vessels that came off the production line. These vessels had been built only to the point of spaceframe completion during the time of the original production. They were then stored away for a short time.

It wasn't until three years later that a solution started to trickle down from the Advanced Starship Design Bureau. This version of the propulsion upgrade solved the Warp Pollution problem and was implement fleet wide, not only on Galaxy Class vessels.

The original version of the Galaxy Class saw it's last days of service around 2373, matching the prediction of twenty years.

It will probably be another twenty years before the Galaxy-Uprated Class with the phaser upgrade is no longer seen in service and is replaced with another uprated or even refit version. However Starfleet is confident that this vessel will continue to perform in its role with the best results, the assumption has only been proved wrong by extreme circumstances in the past. Those lessons are now being studied and accounted for on a regular basis to prevent unnecessary loss of life.

PHASERS

Phaser array arrangement:

Primary Hull:
Three dorsal phaser arrays on the primary hull, one primary dorsal array extending three hundred forty degrees and two point defense arrays to either side of Shuttlebay 1. The arrays cover the entire semi-sphere above the ship, except for a few blind spots close to the hull and Shuttlebay. One ventral phaser array on primary hull, primary ventral array extending three hundred twenty degrees. Array covers the forward and lateral portions of the semi-sphere below the ship, except for those blind spots close to the hull. Total of four phaser arrays on primary hull.

Secondary Hull:
Two dorsal phaser arrays on the secondary hull, both are point defense arrays placed in the far aft of the ship. Three ventral phaser arrays. One primary array with coverage similar to a series of cones with the same vertex and two point defense arrays at the far aft of the ship. Total of five phaser arrays on secondary hull.

Nacelles/Pylons:
One lateral primary array on each vertical bound pylon. Coverage is similar to Secondary Hull's Ventral Primary array. Total of two phaser arrays on Nacelles. On uprated versions the dorsal nacelle housing has one array, making the new total four.

Phaser Array Type: The Galaxy Class has Type-X Phaser arrays. It is the first class to be designed with these arrays; contemporaries have since been refit. Each array fires a steady beam of phaser energy and the forced-focus emitters discharge the phasers at speeds approaching .986c. Current Tactical policy has phaser arrays automatically rotate phaser frequency and attempt to lock onto the frequency and phase of a threat vehicle's shields for shield penetration.

Phaser Array Output: Each phaser array takes its energy directly from the impulse drive and auxiliary fusion generators. Individually, each type-X emitter can only discharge approximately 5.1 megawatts. However, several emitters (usually two) fire at once in the array during standard firing procedures, resulting in a higher discharge.

Phaser Array Range: Maximum effective range is 300,000 kilometers.

Primary purpose: Assault

Secondary purpose: Defense/anti-spacecraft/anti-fighter

TORPEDO LAUNCHERS

Arrangement: Three fixed-focus torpedo launchers, one forward launcher on the secondary and another aft. The third launcher can only be used when the vessel is in Separated-Flight Mode; it is an aft firing launcher on the Primary Hull. Each is capable of firing off ten torpedoes in a single salvo.

Type: Mark XXV photon torpedo, capable of pattern firing (sierra, etc.) as well as independent launch. Independent targeting once launched from the ship, detonation on contact unless otherwise directed.

Payload: Maximum of 275 torpedoes.

Range: Maximum effective range is 3,000,000 kilometers.

Primary purpose: Assault

Secondary purpose: Anti-spacecraft
