Registration NX-50369-A, the USS Temeraire is a first-of-class concept prototype vessel originally built in 2406 for service in First Fleet operations in the Triangulum galaxy. Completed too late for service in that theater of operations, the vessel was mothballed at the Fleet Strategic Reserve at Starbase 319 from 2407-2411. It was reactivated for service at Starbase 99 Versailles in September 2411, where it replaced the Nova class science vessel USS Cerberus.


Design History

The Temeraire class Battle Cruiser was designed in response to engineering reports from the First Fleet, submitted to Starfleet Engineering in 2401. Available evidence, compiled from vessels across the fleet, concluded that navigational phenomena native to the Triangulum Galaxy was undermining the efficiency of Starfleet vessels and front-line units. Many ships and supply depots reported that most standard-issue equipment was being worn out at approximately a third faster than design lifespan.

Additionally, Starfleet forces were often outmatched in combat situations, with larger vessels unable to effectively counter faster and more agile enemy vessels. In response to the reports, officers at Marine Corps Base Syronis VI proposed construction of a new class of vessel for use in Triangulum. Contrary to what one might expect from a requirement for a more agile vessel, after an extended period of testing and evaluation, a heavily-modified Sovereign-class variant spaceframe was selected to form the basis for the class.

Throughout the design and construction process, Starfleet R&D sought to maintain a tradeoff of mobility in favor of firepower and resiliency. The designers also sought a vessel that could weather the local navigational phenomena while possessing the firepower required to lead Starfleet formations in heavy-combat engagements.

The completed prototype of the Temeraire class was fielded for testing in late 2406. However engineering analysis identified a number of flaws, some of which were considered significant enough to merit further testing. While this was underway, First Fleet was ordered to return to the Federation, and production of further units was halted with the prototype and one unit completed. Six other ships were frozen in the framework stage and later disassembled.

In mid-2408 the two existing units were placed in mothballs and assigned to the Fleet Strategic Reserve. All records were placed in storage and the design team was re-allocated to other projects.

Temeraire class Project Objectives

Pursuant to Starfleet Exploration Directives 1016.8 & 1201.12, Federation Diplomatic Corps Mandate 1477.2.2, Starfleet Defense Directives 218.6, 331.1 & 334.7, Starfleet MACO Directive 117.3, and Federation Security Council General Policy, the following objectives have been established for the Temeraire class Battle Cruiser project:

1. Replace the Nebula, Galaxy, and Sovereign class starships as front-line combat units in the Triangulum Galaxy.

2. Supplement the Sovereign class as an instrument of Federation deep-space defensive, scientific, and diplomatic presence.

3. Provide autonomous capability and logistical support for full execution of small-unit operations.

4. Provide autonomous capability and a multi-mission mobile platform for full execution of Federation defensive, cultural, scientific, and explorative policy in deep space or border territory.

5. Serve as a frontline support vehicle during times of war and emergency.

6. Provide non-critical functions such as transport of personnel and cargo when necessary, extended aid, and long- and medium-range patrol.

7. Provide a mobile platform for testing and implementation of mission-specific or new technology of any kind.

Designed several years before class design commenced, the General Electric Class 11c Cryogenic M/ARA drive and power system was selected for installation in the Temeraire. High-power devices, such as the enhanced computer systems, sensor pallets, automated engineering systems, Type-XII phaser arrays, Type-VIII phaser turrets, and tri-axilated regenerative shielding were all determined to be necessary in the early stages of the design process.

The Class 11c warp reactor makes use of six-lobed magnetic constriction segment columns that allow for additional reactant streams to surround the primary stream that travels down the center of the magnetic constrictor columns. This allows for a total of seven reactant streams of both matter and antimatter to collide in the dilithium articulation chamber at a higher velocity than the Class 8 warp reactor in the Sovereign class. The intense thermal reaction (a full 26% hotter than a Class 8 warp reactor) necessitates the use of super-chilled cryogenic coolant to keep the reaction process within acceptable safety limits.

Tactical Systems

Phaser Arrays 12 Type-XII [primary]; 4 Type-VIII turrets [secondary]
Torpedo Launchers 3 Forward; 2 Aft
Magazine 210 Quantum Torpedoes; 600 Photon Torpedoes; 25 Graviton Torpedoes; 25 Veteron Torpedoes

The Temeraire class currently employs 12 Type-XII phaser arrays at key locations throughout the ship's hull. Traditionally the choice defensive weapon onboard Starfleet vessels since close to the dawn of the Federation, the standard emitter makes use of a particular class of superconducting crystals, which allow high-speed interactions within atomic nuclei that create a rapid nadion effect (in turn is directed into a focused beam at a target). The resulting beam is discharged at speeds approaching .986c, and as per standard tactical procedures, the frequencies of these beams are rotated to make it more difficult for a threat vehicle's shields to adjust to the beam.

Phaser Array Arrangement: Six dorsal phaser arrays on the primary hull. Two ventral phaser arrays on the primary hull, extending in nearly a half circle on both the starboard and port ventral sides of the saucer section. Two arrays are located on the dorsal side of the engineering hull at the extreme aft, with two more on the ventral side. The four phaser turrets are positioned to cover the ventral arc, with two located on each beam of the ventral side of the saucer section, one at the ventral midpoint of the engineering section, and one at the extreme aft of the secondary hull.

Phaser Type: The Temeraire class utilizes the latest in starship armament technology, the Type XII array system. Each array fires a steady beam of phaser energy, and the forced-focus emitters discharge the phasers at speeds approaching .986c (which works out to about 182,520 miles per second - nearly warp one). The phaser array automatically rotates phaser frequency and attempts 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 drives and auxiliary fusion generators. Individually, each type XII -emitter can only discharge approximately 8.0 MW (megawatts) per second. However, several emitters (usually two) fire at once in the array during standard firing procedures, resulting in a discharge of approximately 16 MW.

Torpedo Launcher Arrangement: The Temeraire class retains the Sovereign class swivel-mounted torpedo launcher, mounted on the ventral surface of the primary hull, for use against on highly maneuverable starships. Capable of moving 20-degrees port or starboard off the vehicle's primary axis (as compared to 15 degrees on Sovereign class units), this launcher allows for easier tracking of targets at shorter ranges where torpedoes launched from traditional fixed-focus launchers are often unable to track due to the lack of space for course corrections. It is capable of preloading six torpedoes for rapid fire.

Four traditional fixed-focus second generation launchers are located within the secondary hull, with the fore and aft covered by two launchers each. The forward launchers, originally developed for the Defiant Class Project, are located above the main deflector on Deck 15. Each of these launchers is capable of loading five torpedoes in one salvo, typically launched in an alternating interval to reduce the chance that two projectiles may collide in flight. The aft launchers, located on the underside of the secondary hull on Deck 16, are also of the same design (a change from the older model of single-torpedo launcher used on the Sovereign class).

Shields Systems

Sustainable 11,700 MW
Auxiliary Shield 61% of primary efficiency

The Temeraire class includes Tri-Axilated Regenerative Shield Technology (TARST), a variant of the regenerative shield technology first field tested with the Sovereign class before eventual perfection in the Prometheus class prototype. TARST shields make use of redundant shield generators, mounted in clusters of three, which create three meshed shield grids enveloping the entire ship. In combat conditions, the system is capable of creating redundant shields focused on a specific area when integrity drops below a predetermined percentage. This allows the primary shield generator to bear the brunt of incoming fire while the redundant generators remains on hot standby. As the primary generator drops in integrity, power is then increased to the redundant generators which seamlessly take over the burden of shielding for that portion of the ship, allowing the primary generator to once again recharge on standby.

The original Type-8 warp reactor from the Sovereign class was unable to handle the intense power requirements of this system, when combined with other power requirements of this class, leading to installation of General Electric's Type-11c Cryogenic Matter/Antimatter Reactor system.

Compared to other ships of similar mass and hull rating, the Temeraire design is equipped with triple as many shield generators that make up a Regenerative Shield system. The class includes the automatic shifting of shield nutation frequencies, learned as a result of the first Borg encounter at System J-25 and incorporated into all Starfleet ships. During combat, information from the shields is sent to the main computer for analysis where, with the assistance of the tactical officer, the frequency and phase of the incoming weapon is determined. Afterwards, the shields can be reconfigured to match frequency with the weapons fire, but alter its nutation to greatly increase shield efficiency.

There are 78 shield generators in the Temeraire design, 52 more than the comparable Sovereign class, each one generating 150 MW of output. Altogether, this results in a total shield strength of 11,700 MW (matching the original Sovereign class specifications), but only little over half of that is in actual use at one time due to the nature of regenerative shielding. The power for the shields is taken directly from the warp reactor and impulse fusion generators and transferred by means of high-capacity EPS conduits to the shield generators. If desired, the shields can be augmented by power from the impulse propulsion power plants. The shields can protect against approximately 39% of the total EM spectrum, whereas the Sovereign class is equipped to protect against only about 36%, and the older Galaxy class was rated for 23%. This is made possible by the multi-phase graviton polarity flux technology incorporated into the improved regenerative shielding.

The shields, when raised, stay extremely close to the hull to conserve energy, the average range of which is 20 meters away from the hull. This can be extended at great energy expenditure to envelope another starship or object within two kilometers of the starship.
