No known vessel is capable of surviving these speeds as the slipstream drive would rip itself from its housing causing catastrophic damage to the Quantum Slipstream system as well as surrounding systems and ship. Such a procedure should only be used in a dire emergency.

History
Gamma Quadrant
Commissioned in 2419, the USS Cassini was the first Titan Class vessel to complete construction. Cassini was entrusted to a new, yet capable commander, Captain Tellara sh'Zarath. After her shakedown, Cassini was dispatched on a negotiated six month mission to the Gamma Quadrant, deep within Dominion space to investigate Preserver ruins with a joint Federation/Romulan and Dominion expedition.

The mission was ultimately unsuccessful in locating Preserver ruins, the trail seemingly running cold, however was credited in locating numerous sites of archaeological interest, which the Federation council entered in negotiations with Dominion Command for a renewed access period to investigate further.

Return to the Beta Quadrant
House Mo'Kai's Discovery
The Cassini returned to the Beta Quadrant in late 2419, rejoining the 38th Fleet as it had originally been slated for. The Cassini was quickly pressed to work within the Briar Patch where along with a taskforce of 38th Fleet vessels, she was assigned to investigate a colony of P.Stellaviatori within the Briar Patch.

During the ensuing firefight with hostile Klingon vessels, Cassini attempted a so called “Riker Manoeuvre” at close range to the U.S.S. Endeavour. Unfortunately, due to the volatile nature of the Briar Patch, a Klingon ship ignited the metreon gas cloud, engulfing the Endeavour and Cassini in an interstellar eruption that threatened to destroy the entire patch. The Cassini was successful in stopping the wave, however the resulting damage destroyed the starboard ramscoop, her first major damage since construction, requiring a two week period in drydock. After her repairs, Cassini participated in multiple other skirmishes with House Mo’Kai, including participating in a taskforce to head off a Mo’Kai attack fleet headed for the U.S.S. Enterprise and I.K.S. Bortasqu’. Cassini’s improved defensive and tactical systems proved highly effective in the skirmish, resulting in only minor damage to the improved shielding systems, with no hull damage.

Technical Data
Physical Arrangement and Crew Support
Measuring at over 450 meters and with 18 decks, the design of the Titan-class consisted of two hull sections: an oval-shaped primary hull and a secondary hull which mounted two warp nacelles. Cassini was designed to carry a standard compliment of 350 officers and crew. In an emergency situation, the Titan-class was rated to carry up to 1,250 passengers for a limited duration.

While the Cassini was rated as a long range explorer-type, accommodations for civilian families were limited on the Cassini. Typically being limited to scientific and facilities contractors rather than crew families. A range of typical amenities were available to the ship's crew, including a number of holodecks and recreational facilities. Cassini possessed one full sickbay with all facilities while also maintaining smaller triage areas and a sizable array of science labs.

Translatteral Transporter System
The Cassini was equipped with a Translatteral Transporter System which has two main improvements over the standard Transporter system.

First, the transport cycle length is reduced from 5 seconds, to 3 seconds, attributed due to enhanced targeting sensors and increased emitter bandwidth. Secondly, the Translatteral Transporter can allow effective beaming through shields so long as the emitter frequency was synchronised with the shield frequencies of both the originating pad and destination. Keeping synchronization with the Cassini’s shield frequency was an easy task, and in most cases the system was only optimised to allow transport through the Cassini’s shield arrays.

While the system may be used to transport through the shields of a hostile or friendly target, the Cassini’s shield array must also be matched to the frequency of the destination array, which has the unfortunate result of increasing effective shield penetration from hostile craft.

Command and Control Systems
The computer systems aboard the Titan-class were based on isolinear circuitry, with additional bio-neural gel packs positioned throughout the vessel. The ship employed two computer cores, one each in the primary and secondary hulls. Operational control of the ship was provided by the main bridge, located on Deck 1. While Titan-class ships were capable of saucer separation, the process would be destructive and irreversible without the support of a starbase.

Propulsion & Power Generation
Cassini was equipped with a standard Class 12 matter/antimatter warp drive, of General Electric ADS/03 specification, with an average output of 1650 Cochrane. Her standard cruising velocity was Warp 7.5, with a maximum cruise of up to Transwarp 12.84. Cassini was rated for a top speed of Transwarp 13 for a period of up to 1 hour. Sublight propulsion was achieved primarily through the use of the vessel's large twin impulse engines, located on the trailing edge of the primary hull. Fine manoeuvring control was provided by RCS Thrusters.

The warp core serves as the primary source of power for all ship systems, supplanted by the vessel's conventional deuterium fusion and impulse reactors.

Stealth Systems
The Cassini was equipped with state of the art stealth technology, without resorting to cloaking devices not permitted under the Treaty of Algeron. These technologies are only effective at sublight speeds, with any acceleration to or deacceleration from warp speeds being noticeable due to the burst of gamma radiation associated with the "warp flash".

Dedicated Static Warp Field Generators
Smaller than the warp coils found within the nacelles and integral to the Cassini's stealth systems, the dedicated Static Warp Field Generators create subspace fields which the Cassini "falls into", allowing it to move without the use of heat-emitting thrusters.

Each of the sixteen generators were rated up to 500 millicochrane allowing an effective total field distortion of 8 Cochrane thus allowing an effective top speed of Warp 1.8 in any direction. To maintain the stealth profile afforded by this configuration however, speeds should be kept under 0.75c. When stationary, only four emitters at 25% power would be required to maintain subspace field integrity, with the resultant 0.5 Cochrane field distortion observed to blend in completely with typical gravitational subspace distortions found within a star systems heliosphere.

An additional effect of this subspace distortion means that 89% of total EM emissions from the Cassini would register as background radiation once they have passed back through the subspace barrier layer. These can be mitigated further by operating in traditional silent running modes to reduce total EM output.

The fields were also capable of lowering the Cassini’s effective mass, allowing planetary entry and egress where other vessels of a similar classification and weight would be unable to enter without risking a loss of hull integrity.

Internal Emission Sinks
In combination with the above, an extensive array of lithium sinks located within the computer cores and beneath the exterior hull collect 98% of all IR emissions through an extensive Helium-3 distribution network surrounding the vessels primary and exterior systems.

The Cassini was capable of operating in full silent running to allow passive observation of a star system for up to 3 days, and would be able to operate in an active scanning role for 4 hours before the vessel’s heatsinks begin to emit lethal levels of heat into the habitable area.

Tactical & Defensive Systems
In addition to advanced regenerative deflector shielding and ablative hull armor, Cassini also carries an impressive array of weaponry for her class.

Two dorsal phaser arrays were located on the primary hull, allowing 250° coverage with another four further dorsal aft phaser arrays (two on the secondary hull, two on the nacelle pylons) providing the remaining 110° dorsal coverage. A set of additional phaser arrays were installed in the mission pod and above the shuttlebay, the former with its own 360° coverage facing directly above while the latter faces aft. On the ventral side, a further two phaser arrays were located on the primary hull, with two also located on the nacelle pylons, mirroring the locations and coverage of the dorsal arrays. In the center ventral section of the engineering hull was another phaser array, providing 360° coverage directly below. A final point phaser array was located between the two front torpedo tubes providing an effective last moment screen covering the deflector dish.

Two twin-tube photon torpedo launchers (one facing fore, one aft) were present at the midline of the secondary hull, connected to a singular magazine holding a maximum of 300 torpedoes, probes and other heavy armaments.

FSS6-X Cyclic Regenerative Shielding (CRS) Array
The Cassini was also equipped with an experimental FSS6-X Cyclic Regenerative Shielding (CRS) Array. Developed in joint partnership with Dominion Engineers, the CRS attempts to solve the higher-end limitations of traditional deflector shielding technologies. Traditional deflector shielding cannot completely block high energy discharges such as kinetic forces from torpedo impacts or volatile energies from interstellar phenomenon.

The CRS violently slaps aside rather than halting incoming linear force. By rotationally firing their graviton polarity projectors, ships equipped with the CRS create rapidly oscillating deflector screens instead of static ones. Shooting through the CRS was like trying to shoot at a target inside a spinning ball.

Significant drawbacks to current CRS configuration prevent its use on anything other than destroyers, frigates and smaller craft. Its many high-frequency sensors and emitters require frequent maintenance and replacement. A partially damaged CRS can endanger its operator, who would be surrounded by rotating graviton fields skewing in unpredictable directions. Fortunately, if an emitter were to be damaged, the CRS corrects to become a traditional shield array, a safety feature that makes it most effective during opening volleys.

Auxiliary Spacecraft
The Cassini was equipped with a single large shuttlebay, located along the aft engineering hull of the vessel. In addition eight large landing pads behind the shuttlebay were able accommodate several runabout-type vessels, and the entire section may be covered in a forcefield to support shirt sleeves maintenance of landed vessels, however this area was not intended to such transport craft at anything other than sublight speeds.

Cassini, carried six Type 8 shuttlecraft, and four “Workbee” pods as her standard complement of smallcraft, with an additional two large Type 11 Shuttles, two Argo Runabouts and a singular Delta class Runabout.
