The Constitution-class was a Federation heavy cruiser starship in Starfleet service in the mid-to-late 23rd century. The design underwent several refits in its many decades of service. The original configuration and refit variants of this class influenced starship design significantly, and accelerated the standardization of the fleet.

Celebrated members of the class included the USS Enterprise and the USS Enterprise-A—two of the most venerated starships in Federation history, having risen to prominence under the captaincy of James T. Kirk.

The Constitution-class was a Federation Starship-class, Class I Heavy Cruiser. They were the premier frontline Starfleet vessels in the latter half of the 23rd century.

They were designed for long duration missions with minimal outside support and were best known for their celebrated missions of galactic exploration and [[d

History[]

Development[]

Development of the Constitution-class began in the 2230s when key Fleet personnel, including Admiral William Jefferies and Captain Robert April, came to see the necessity of an all-purpose vessel that could explore space while protecting Federation interests and expanding its reach. When a design team led by Doctor Lawrence Marvick finished plans late in that decade for just such a ship, a new class was swiftly approved by Starfleet Command.

Starfleet authorized its Fleet Yards in San Francisco to build two vessels, with Admiral Jefferies overseeing NX 1700 -- christened Constitution -- and Captain April supervising its sister ship 1701, as yet unnamed.

The USS Constitution's hull was completed in 2244, with enhanced sensor and deflector shield systems installed. When hostilities broke out late in the year, Jefferies pulled her from drydock to take decisive part in the Battle of Donatu V. Blunting the Klingon invasion force -- without weaponry -- she rescued USS Yorkshire but was badly damaged and required extensive repairs.

The USS Enterprise (NCC-1701)

Construction on NX 1701 continued apace, employing new Duotronic computer systems designed by Doctor Richard Daystrom, which afforded 1701 better control of her systems. After a secret mission into the Romulan Neutral Zone, April christened her the Enterprise.

By 2245, both the Constitution and the Enterprise had begun their first five-year missions of exploration, the results of which led Starfleet to order nine more ships of the class.

Refit[]

One of many proposals for the Constitution refit project

Beyond minor modifications, the successful design saw no major changes until the 2270s, when a significant refit had been more than earned. Upgrade proposals all shared a more efficient power plant, with some versions streamlining the hull for better warpfield geometry, and others emphasizing enhanced weaponry or science capability; the final design merged many of the proposals.

The refitted USS Enterprise

The first major refit was Enterprise, and its success ensured the refit of the rest, bringing the fleet in line with newer technologies and extending its life.

Later service[]

A Constitution-class ship served into the late 24th century and was destroyed in battle at Wolf 359; others, reactivated or still in service, fought in the Dominion War, and took part in the task force to retake Deep Space 9.

At least one decommissioned Constitution-class ship was sold to a private entity; later known as Glory, it was acquired by Romulans and given to privateer Deigo DeBlazio to harass Federation shipping.

The construction of the Constitution-class started again in late 24th and early 25th centuries, it was designated as a standard cruiser and the commanding officer was commonly a Lieutenant Commander.

Alternate timeline[]

The Constitution-class sarship of the alternate timeline

In an alternate timeline, the Federation was at war with the Klingon Empire in 2400. The USS Hoshi Sato was more advanced in weaponry and very similar to the Kelvin timeline Constitution class starship. The Constitution-class of this timeline had a more militaristic design then that of its primary universe counterpart, with phaser banks firing both multiple short burst rounds or steady beams along with torpedoes simultaneously in a barrage. The torpedo bay was located in the same position as the post-refit version from the original timeline. The phaser arrays are located on the dorsal and ventral sides of the saucer section and resemble the ball-turret style, also used in the post-refit version of the original timeline's class; firing red pulses (like proximity blasts), capable of continuous fire. The bridge is located on deck 1 and sickbay is located on deck 7. The crew size is 1100.

Specification[]

The largest and most elaborate vessel class Starfleet had yet fielded, with an unprecedented fourteen research labs each, ships of the Constitution-class became the most extensive mobile research platforms ever deployed by the Federation, and were responsible for expanding known space by thousands of cubic parsecs.

The class utilized a greater level of modularity, which allowed for incremental changes to configuration -- so flexible that it became standard starship design practice. As other classes began to employ such modularity, Fleet design became increasingly more uniform.

The Enterprise en route to Starbase 13 after a saucer separation

The Constitution class were also among the first to allow for primary-hull saucer separation -- though only in emergencies, since the separation's use of explosive bolts required starbase facilities for reconnection. By the 24th century, the saucer separation had become a routine maneuver with Galaxy-class starships having the ability to separate their saucers, and reconnect them.

The USS Enterprise landed in 2266

The saucer section of the class was also capable of making an emergency planetary landing using retractable landing gear. A boarding ramp could be lowered from the dorsal connector point to allow crew on and off the ship.

The Constitution vessels of the original series had slightly different features than the succeeding subclasses Bonhomme Richard, Achernar, Tikopai and Enterprise, with early laser and phaser weapons available to security teams onboard as hand-held weapons, as well as ship-mounted emplacements, in concert with accelerator cannons and photon torpedo launchers. The Constitution vessels of the 2240s and 2250s began the use of the class's standard emplacements, with forward arcs of fire. Most early Constitution variants had 6 phasers, usually dual mounted, in 3 or more phaser banks, although some variation exists between the various subseries. For example, the one modifications of the Enterprise modification had a series with 8 phasers in 4 banks.

Starships of the Bonhomme Richard modification, such as the Enterprise, had forward firing phaser banks that could fire beams or pulses, located on the lower saucer section, just above the sensor dome and a torpedo launcher. The Defiant was noted to use, with dramatic effect, its rear firing phaser and torpedoes located above the secondary hull's shuttlebay, as well as the upper saucer banks.

Some vessels of the Achernar series, such as the USS Constitution had port and starboard upper saucer phasers as well as a forward firing phaser on the lower saucer and upper and lower saucer torpedo tubes. All of the Achernar series weapons were forward or side firing, leaving the rear arc uncovered.

The Enterprise-subclass, with one more launcher than the preceding series, had a move in the torpedo launchers to an outrigged tube control room at the separation between the secondary hull and the connecting hull. By subsequent Enterprise modifications, the rear arcs had been restored.
