}}The '''''Constitution''-class''' heavy cruiser is a legendary starship design often considered to be the exemplar of both [[Starfleet|Starfleet’s]] mission and its design ethos. First built in the 2240s, they remained Starfleet’s premiere heavy cruiser until the 2270s, having been refit and overhauled numerous times over those three decades until the changes became so substantial that the class was succeeded by its Enterprise sub-class, known officially as the [[Constitution II|''Constitution II''-class]].


==History==
==History==
===Genesis===
By the 2220s, the [[United Federation of Planets]] Starfleet had established its mission and its philosophy as being distinct both from the [[ma:Earth Starfleet|United Earth Starfleet]] and the stellar services of the Tellarites, Vulcans, and Andorians, but its shipbuilding practices continued to be largely fragmented. Vulcans built science ships, Andorians built warships, Tellarites built trade vessels, and Humans built a little bit of everything. In some ways this was advantageous—national shipyards could excel in what they were good at—but the Federation had yet to truly synergize the strengths of its member worlds into a cohesive technological platform. Named for the idea of the governing documents of a union serving to strengthen its people, Project Constitution was ordered in 2230 as a way of unifying the technological abilities of the Federation’s members into a single vessel that would embody Starfleet’s core missions of exploration, diplomacy, defense, and mercy for missions far beyond explored space.


===Early Life and Vulcan Science Academy (2304-2330)===
Starfleet Engineering created the Advanced Starship Design Bureau to design the Constitution, with its headquarters and production facility located in the heart of the Federation at [[ma:San Francisco Fleet Yards|San Francisco Fleet Yards]]. The design process was slow and methodical, taking nearly fifteen years before the first two vessels left the yards. The brief was not just to create a starship that incorporated aspects of various member worlds’ achievements but to go beyond them to create a vessel that innovated in every area. This would be the largest, most elaborate, and most capable starship yet fielded by Starfleet, taking on a crew of 500 humanoids for voyages of five years with minimal outside support.
Karrik was born in the southern hemisphere of Vulcan in 2304. He had a relatively uneventful childhood, being the third son of a pair of scientists. His parents both studied xenobiology, so it wasn't surprising at all for him to enter the Vulcan Science Academy at age 20, where he, too, would study life on other worlds. Karrik was noted by his instructors not for being particularly imaginative or innovative, but for dutifully following the scientific process methodically and minutely. After six years at the Vulcan Science Academy, Karrik was preparing to join a lab on Vulcan, before he considered that Starfleet would give him better opportunities to actually ''meet'' life from other planets.


===Early Starfleet Career (2330-2348)===
''Constitution'' herself, NX-1700, and the yet-unnamed NCC-1701 were laid down at San Francisco Fleet Yards in 2234, the former under the supervision of Admiral Matt Jefferies and the latter under then-Captain [[ma:Robert April|Robert April]]. The construction project was a truly multi-species affair, with each systems team purposefully composed of officers from across Starfleet’s own yards and the shipyards of member races. This initially led to conflict, but the management styles of Jefferies and April allowed every member of each team to find their own way of contributing to the project as a whole—this also served as a blueprint for operational procedures and command techniques for managing large multi-species crews, as this was something that Starfleet still lacked significant experience in.
Despite already being a very competent scientist, Karrik had no experience with starships, and so he matriculated into Starfleet Academy as a cadet in 2330, so that he could fill out his education as a Starfleet Officer. Being around non-Vulcans for the first time in his life was strange, as he'd had an incredibly sheltered adolescence on Vulcan. He found this experience so disconcerting, that following graduation he requested a posting to a starship with an all-Vulcan crew. He was granted this request by being posted as an Ensign to the ''Excelsior''-class starship USS ''Selar'', which was assigned to survey missions in the Beta Quadrant.


The ''Selar'' was Karrik's home for 14 years, where he advanced through the lieutenant grades by 2348. Because his family wasn't of any particularly high social standing, he didn't have a betrothed, so it was also here that he met his wife: V'Len, a flight control officer on the ''Selar''. The two of them took a leave of absence from 2348 to 2355 when V'Len became pregnant with their first child.  
Thanks to the success of the construction process, the order was increased to six vessels in 2238, and ''Constellation'', ''Republic'', and ''Intrepid'' were laid down that same year.


===USS ''Adelphi'' (2355-2362) ===
As the design evolved, many areas of the ''Constitution''-class spaceframe were built to be modular and easily reconfigurable to allow the design to be upgradeable, something that proved to be prescient as the class would have many minor upgrades and two major redesigns over its service life. The saucer section in particular was designed to be able to handle anywhere from two-hundred to five-hundred crew, with space for labs, recreational facilities, and sickbays alterable to suit different mission parameters and crew sizes. This was made possible by locating the majority of the ship’s larger equipment—the deflector dish, warp core, cargo holds, hanger, etc.—in the secondary hull, so that the primary hull was reserved for crew support and mission-specific equipment. The initial two vessels were configured to support a crew of 450, with a generalist lab arrangement and volume reserved for diagnostic computers to evaluate them during their shakedowns.
Following his leave, Karrik applied to rejoin the fleet, while V'Len elected to stay home on Vulcan with their child. Karrik was promoted to Lieutenant Commander and was assigned to the starship ''Adelphi'' as its Chief Science Officer. Unlike the ''Selar'', the ''Adelphi'' was a mixed-species crew, which took a lot of getting used to for the Vulcan commander, but he acquitted himself well when he realized that the same techniques he used to study unknown lifeforms could also be used to analyze his subordinates to decide which stimuli would achieve the desired results with them.


During this time period, the ''Adelphi'' surveyed a number of previously un-charted M-class worlds, which allowed him to publish a number of papers on unique organisms and proper specimen collection techniques. As with his time at the Vulcan Science Academy, though, Karrik was noted for being precise and dutiful, but someone who tended to wow anyone. This slowed his advancement, but Karrik himself wasn't particularly eager to enter a starship command role.
The prototype, ''Constitution'', was launched in 2244 and undertook an extensive six-month shakedown cruise in the core of the Federation while NCC-1701 continued under construction. A year later, the second prototype was unveiled as the first Federation starship to bear the name ''Enterprise'', named after the Earth Starfleet vessel widely considered to be the primary instrument leading to the founding of the Federation. Her launch was followed quickly by Constellation, which was completed more quickly thanks to lessons learned along the way of building the first two.


=== Science Station V-21 (2362-2378) ===
===Early Service===
In 2362, Karrik accepted a posting to science Station V-21, which was located in orbit over a Class-O pelagic planet, which was noted for having among the highest levels of biodiversity ever recorded by Starfleet. From this station, as executive officer, he would lead a number of studies into the aquatic life forms found on the planet below. This posting allowed his wife, V'Len, and their son, Lest, to join him, an arrangement that he found to be agreeable. In 2370, Karrik was promoted to commander and became the commanding officer of the base, a role that he would serve in through and beyond the Dominion War. His station was largely untouched by the conflict, but he found himself frequently short-handed and under-resourced to complete his primary mission, but he appreciated having a role that kept his family out of harm's way.
''Constitution'', ''Constellation'', and ''Enterprise'' were sent on their first five-year missions in 2245, with Captain [[ma:Garth|Garth of Izar]] commanding ''Constitution'', Captain Robert April commanding ''Enterprise'', and Captain [[ma:Matt Decker|Matt Decker]] commanding ''Constellation'', under the careful watch of Admiral Jefferies. The initial three ships were very successful in their first two years of service, and even as ''Republic'' and ''Intrepid'' were still nearing completion, Starfleet increased the order to twelve total ''Constitution''-class starships. A number of other classes using the same technological base, such as the ''Bellerophon'', ''Radiant'', and ''Archer'' classes were also ordered around this time.


In 2378, Karrik retired from Starfleet and returned to Vulcan with his family. During this time, he continued publishing papers on his experience from V-21, which helped him develop a reputation as an expert xenobiologist. If the Romulan crisis of the 2380s hadn't developed, it's likely that he would have continued on as a civilian scientist for the remainder of his life, but when Utopia Planitia was destroyed in 2385, he volunteered to return to service.
The concept of a Five-Year Mission was prototyped aboard the original ''Constitution''-class vessels as a new way of managing the command and staffing of starships. It was not uncommon for short-range vessels to have a captain for a few months at a time or even for a single mission and regular contact with starbases allowed for frequent crew rotations. As the ''Constitution'' was intended to be much more independent, a structure was developed that commissioned each captain to a five-year stint aboard their vessel, with a command crew that was intended to be more or less stable. This required new regulations for managing crew advancement in the field, as well as new strategies for making a starship a comfortable and fulfilling place to spend five years of one’s life.


=== USS ''ShirKahr'' (2385-2393) ===
===Mid Career===
Due to his command experience, Karrik became the executive officer aboard the USS ''ShirKahr'', an ''Atlantia''-class ship which was assigned to relief missions along the Romulan border. While the Federation Council's decision to halt the rescue effort following the attack on Mars, the ''ShirKahr'' still spent the majority of its time tending to refugee worlds and former Romulan worlds that were now part of Federation space, following the collapse of the Romulan Star Empire in 2387. As this ship was not a science vessel, Karrik was forced to develop quickly as both a logistician and a diplomat, given that they were often dealing directly with refugee settlements. After a long career as a scientist, Karrik had thought himself to be past the point where he needed to learn new skills, but he slowly began to find satisfaction in the challenges associated with command.
In 2250, ''Constitution'', ''Constellation'', and ''Enterprise'' all completed their first five-year missions to widespread acclaim. While Garth of Izar and Decker remained at their posts, Robert April was promoted to flag rank and, as the newly-minted Director of Deep Space Operations, became the supervisor of the entire Constitution fleet.


In 2390 at the age of 86, Karrik was promoted to captain and assumed command of the ''ShirKahr'', when it was diverted to a new theater of operations on the other side of Federation space, to help colonies in the [[Former Demilitarized Zone]] in the face of the True Way crisis.  
A decade into their service, the ''Constitution'' class received their first major overhaul in 2255, with widespread systems upgrades and a shrinking of the crew by two hundred to optimize them for longer deep space missions. This allowed for larger and more spacious quarters, as well as less strain on the life support systems. The members of this class were absent from the [[ma:Federation-Klingon_War_(2256-57)|Federation-Klingon War of 2256-57]], as Starfleet wanted to keep them in reserve. As the class was a large investment of both resources and crew, Starfleet rush-ordered a leaner variant that would replicate the engine and tactical systems of the ''Constitution'' but with a much smaller crew: and a much shorter construction period the ''Sombra''. Few of these vessels were built, given the short duration of the war, and they were all refit as Constitution-class ships with full exploratory systems by 2260.  


=== USS ''K'Ehleyr'' (2393-Present) ===
Following the war, Starfleet prioritized the construction of classes that were derived from the ''Constitution'', including the new ''Miranda'', ''Hermes'', and ''Saladin''-class vessels that were directly built from Constitution-type components. This building program included a handful of ''Constitution'' orders which made up losses in the years following, bringing the total ''Constitution''-class fleet up to 12 by 2265.
In 2393, Karrik was selected to command the brand-new ''Resolute''-class starship ''K'Ehleyr''. This heavy cruiser was predominantly assigned to transport ambassadors and flag officers during Karrik's command, which is a task that he was well-suited to. He was content to remain outside of the spotlight, making sure the ship completed its mission effectively, but allowing whichever VIP the mission was assigned to to take the lead. He continued in this role when the ship was assigned as the flagship for Task Force 72 in 2399.


=== Service History ===
Most ships of the ''Constitution'' class retained their 250-person crew into the 2260s, when the next major overhaul returned the core twelve vessels to a 450-person crew. The hull was also encased in a thin layer of metalo-ceramic armor, which gave them their now-classic, stark exterior. While serving still primarily as explorers, this refit also incorporated fewer but heavier phaser banks as a response to simmering tensions on the Klingon border.

== Captain Karrik In-Play ==
===Later Life===
Though these vessels proved to be highly successful in service, ''Defiant'', ''Constellation'', ''Intrepid'', and ''Excalibur'' were all either destroyed outright or lost with all hands during the period between 2265 and 2270. While each of these circumstances was extraordinary and no underlying flaw was found in the class itself, Starfleet ordered an extensive overhaul, starting with the refit of the ''Enterprise'', a project which eventually became the ''Constitution II''-class heavy cruiser.


* Captain Karrik makes sure the trains run on time, which makes him really great as a flag captain, because he can competently handle running the ship while the flag officer makes decisions about the wider galaxy.  
Throughout the 2270s, the majority of the ''Constitution''-class vessels were upgraded into ''Constitution II''-class vessels, with the exception of the USS ''New Jersey'', which was not launched until 2268 and thus was considered too new to upgrade. ''New Jersey'' was decommissioned after 20 years of service in 2288, having stubbornly resisted a refit, and was placed in the Starfleet Museum, where she remains as of 2401: the last remaining example of an original configuration ''Constitution''-class starship.
* Karrik values following protocol and respecting hierarchy.

History

Genesis

By the 2220s, the United Federation of Planets Starfleet had established its mission and its philosophy as being distinct both from the United Earth Starfleet and the stellar services of the Tellarites, Vulcans, and Andorians, but its shipbuilding practices continued to be largely fragmented. Vulcans built science ships, Andorians built warships, Tellarites built trade vessels, and Humans built a little bit of everything. In some ways this was advantageous—national shipyards could excel in what they were good at—but the Federation had yet to truly synergize the strengths of its member worlds into a cohesive technological platform. Named for the idea of the governing documents of a union serving to strengthen its people, Project Constitution was ordered in 2230 as a way of unifying the technological abilities of the Federation’s members into a single vessel that would embody Starfleet’s core missions of exploration, diplomacy, defense, and mercy for missions far beyond explored space.

Starfleet Engineering created the Advanced Starship Design Bureau to design the Constitution, with its headquarters and production facility located in the heart of the Federation at San Francisco Fleet Yards. The design process was slow and methodical, taking nearly fifteen years before the first two vessels left the yards. The brief was not just to create a starship that incorporated aspects of various member worlds’ achievements but to go beyond them to create a vessel that innovated in every area. This would be the largest, most elaborate, and most capable starship yet fielded by Starfleet, taking on a crew of 500 humanoids for voyages of five years with minimal outside support.

Constitution herself, NX-1700, and the yet-unnamed NCC-1701 were laid down at San Francisco Fleet Yards in 2234, the former under the supervision of Admiral Matt Jefferies and the latter under then-Captain Robert April. The construction project was a truly multi-species affair, with each systems team purposefully composed of officers from across Starfleet’s own yards and the shipyards of member races. This initially led to conflict, but the management styles of Jefferies and April allowed every member of each team to find their own way of contributing to the project as a whole—this also served as a blueprint for operational procedures and command techniques for managing large multi-species crews, as this was something that Starfleet still lacked significant experience in.

Constitution, Constellation, and Enterprise were sent on their first five-year missions in 2245, with Captain Garth of Izar commanding Constitution, Captain Robert April commanding Enterprise, and Captain Matt Decker commanding Constellation, under the careful watch of Admiral Jefferies. The initial three ships were very successful in their first two years of service, and even as Republic and Intrepid were still nearing completion, Starfleet increased the order to twelve total Constitution-class starships. A number of other classes using the same technological base, such as the Bellerophon, Radiant, and Archer classes were also ordered around this time.

Mid Career

In 2250, Constitution, Constellation, and Enterprise all completed their first five-year missions to widespread acclaim. While Garth of Izar and Decker remained at their posts, Robert April was promoted to flag rank and, as the newly-minted Director of Deep Space Operations, became the supervisor of the entire Constitution fleet.

A decade into their service, the Constitution class received their first major overhaul in 2255, with widespread systems upgrades and a shrinking of the crew by two hundred to optimize them for longer deep space missions. This allowed for larger and more spacious quarters, as well as less strain on the life support systems. The members of this class were absent from the Federation-Klingon War of 2256-57, as Starfleet wanted to keep them in reserve. As the class was a large investment of both resources and crew, Starfleet rush-ordered a leaner variant that would replicate the engine and tactical systems of the Constitution but with a much smaller crew: and a much shorter construction period the Sombra.
