The Constitution-class (Refit) is a class of Federation starship that served in Starfleet throughout much of the twenty-third century.


General Overview

Class History

Perhaps the most famous class of vessel in Starfleet history, the USS Constellation (NX/NCC-1017) set a new standard of excellence in almost every applicable field - she was simultaneously the fastest ship, most advanced exploration platform and most powerful combat vessel in known space. The USS Constitution (NCC-1700) was constructed and launched following intensive tests of several of the Constellation’s sister ships. The results from years of testing these vessels where poured into construction of the Constitution, making her the most advanced vessel of the design. Because of this, Starfleet deemed it necessary to call the design the Constitution Class and immediately set to constructing more of these vessels while upgrading those already constructed to bring them up to the Constitution’s standards.

Quickly following the Constitution in 2245 was the USS Enterprise (NCC-1701). This was to become the most famous vessel in Federation history; during her years of service life the Enterprise explored countless new worlds, making first contact with many species and expanding the Federations knowledge of the territories surrounding it hugely. Like her sisters the Enterprise also served as a mighty deterrent to both the Klingons and Romulans, several times taking part in combat actions which determined the fate of the entire Federation if not the Alpha Quadrant itself. The Constitution class ships where designed for long duration missions with minimal outside support, and exploratory missions typically lasted up to five years. The Enterprise conducted several such missions, first under Captain Robert April and then under Captain Christopher Pike, followed by Captain James T. Kirk. Kirk commanded the Enterprise through her most difficult missions, and it is largely because of his incredible success that the Constitution class has acquired the reputation it has.

Other ships of the class were less fortunate than the Enterprise; the USS Defiant (NCC-1764) was lost in an interphase pocket in 2268. The USS Excalibur (NCC-1664) and USS Lexington (NCC-1709) were badly damaged in the unfortunate M-5 incident - Excalibur's entire crew was killed in the incident. Except for her Captain, a deadly alien virus killed the entire crew of the USS Exeter (NCC-1672) in 2268. The USS Constellation was destroyed fighting against the Doomsday machine, again with the loss of her entire crew.

By 2265 the early Constitutions where reaching twenty years of age, their designed life span. Starfleet had decided that they where becoming somewhat long in the tooth and was looking for a replacement class; however, such was the popularity of these ships that the Starfleet design bureau stated in an official memo that none of the contemplated new designs matched up to them and the best course of action was to simply rebuild the existing ships with the latest technology. Although Starfleet was not convinced at first, careful testing of the skeleton framework of several Constitution class ships revealed that the basic structure was more than capable of continuing in service, having withstood twenty years of hard use with ease.

The USS Enterprise was selected to be the first ship to undergo such a refit, and in 2269 she went into dock in Earth orbit for eighteen months of work. Never in Starfleet history has any vessel been so comprehensively updated - essentially a new vessel was built onto the bones of the old, replacing virtually every major system. The Enterprise was rushed out of dock in 2271 to face the threat presented by the entity known as V'Ger, which was destroying everything in its path as it advanced towards Earth; she succeed in averting the danger and proceeded on her shakedown cruise.

Once the Enterprise was through her shakedown cruise successfully the remaining Constitutions where refitted in quick succession. The new ships proved to be more than capable of carrying out their normal exploratory and scientific roles, while in the combat arena they where judged an easy match for the Klingon K'T'Inga class. The Constitutions continued in service for a further three decades, and once again the Enterprise set the standard for the rest of the ships to follow. After her shakedown the ship conducted another five-year exploratory mission under Admiral Kirk before being transferred to training duties in 2277 under Captain Spock. She continued in this role for a further eight years, and many of Starfleet’s most successful officers went into space for the first time aboard this ship. In 2285 the Enterprise suffered heavy battle damage while preventing Khan Noonien Singh from stealing the Genesis Device; the ship was to be retired at this point, but Kirk and his officers stole her and took her to Genesis to retrieve Captain Spock's regenerated body from the planet. The Enterprise was attacked and crippled by a Klingon Bird of Prey while at Genesis, and was subsequently destroyed by Admiral Kirk shortly after the Klingon crew boarded to take control.

The USS Yorktown was subsequently renamed as the second Starship Enterprise (NCC-1701-A), and assigned to the now Captain Kirk. The Enterprise (nee Yorktown) had recently emerged from a major refit, and the ship suffered many technical problems on her first mission; nevertheless, she went on to serve the remainder of her service life with distinction.

As of the year 2290, the Constitution Class remains the most versatile design within the Federation Starfleet, and although production of these vessels has ceased due in part to the Excelsior Class vessels being produced at a faster rate, the Constitutions will remain in service for at least another 10-15 years, serving alongside their new more advanced cousins. It is estimated that the majority of the Constitution Class will be phased out of service over the next 5-10 years, a small number of which will be stowed in Starfleet reserve shipyards, and at least 3 vessels are scheduled to become Museums, public or otherwise. The remaining Constitutions will likely be decommissioned by 2305 as projections predict that the Excelsior, Okinawa and Phobos Classes will exceed their original construction goals.
