USS Yorktown Specifications

Vesta-class Multi-Mission Explorer

Background: In 2386 a new and advanced class of Starship entered service in Starfleet. The class was designated a multi-mission explorer and was testbed for a number of experimental technologies, including quantum slipstream drive.

As of February 2387, there were seven vessels of the class in service.

The Vesta Class starship USS Aventine was the testbed for a number of new Starfleet technologies, including quantum slipstream drive which could allow the vessel to travel 65,000 light years in just three months. Systems installed as part of the slipstream drive included a quantum field focus controller at the front of the ship's main deflector and a chroniton integrator.

The quantum field focus controller allowed the starship to keep shields and communication online and at 100 percent during slipstream travel. It could also be used as a beam intensifier.

If the ship is heavily damaged and the field focuser is still online, power from the phasers and shields could be rerouted to the main deflection system and be used to ether create a shield bubble or a high intensity phaser beam which could be sustained for as long as power can be routed to the deflector array.

The chroniton integrator could be used to take sensor readings several seconds into the future when the ship was using its slipstream drive.

Other experimental systems aboard the Aventine included a multidimensional wave-function analysis module, and a sympathetic fermion transceiver. Some of the systems being tested were deemed top secret.

The multidimensional wave-function analysis module allowed the Vesta-class starship to detect inter-dimensional rifts in subspace and temporal distortions in space time up to 23 light years away, and it also emits a multidimensional graviton shield which in theory can reverse the effects of a dimensional worm-hole e.g. a worm-hole absorbs light and matter, but with a Multidimensional wave-function analysis Module matter i.e. a starship would be pushed away from the event horizon.

Because of the Vesta Class ships use of several experimental technologies, much of the class's history is currently classified, however in the early 2390s the class was upgraded with new Type-XIII phaser arrays and improved power allocation systems.

### Timeline

2375: Starfleet issues a general design brief for a multipurpose vessel capable of deep space, combat, and diplomatic missions. The general idea is for a modular starship based around the specifications of the Sovereign class currently being built.

2376: Starfleet views the Theoretical proposals for the Vesta. After deliberation the Vesta's primary Design is approved and briefs for the propulsion, computer, weapons and spaceframe parameters are sent out to Starfleet Design agencies for consultation.

2377: Propulsion Dynamic are approved and sent to the Jupiter Station for in-depth study. Later in the year MARA design is standardized for the Vesta Class. Spaceframe design is approved, and full specifications are forwarded to Utopia Planitia for designations. USS Vesta Production begins with a projected 9-year turnover for the Prototype ship. Saucer Section is redesigned.

2378: Design work on Warp Coils is approved for the Vesta Class. The Stardrive section nears chassis completion. Saucer section nears 30 percent chassis completion. Warp Nacelles are redesigned. Sensor suite is redesigned based in part data learned during the USS Sovereign's trial runs. USS Aventine begins construction.

2379: Primary and secondary chassis's now at 100 percent completion. Computers are delivered for fitting work.

2380: Work continues on habitat and out hull sections for USS Vesta. Late in year computer cores are activated and ship functions begin to be transferred from station control to ship control. Bridge module is designed. Weapons systems from Sovereign class modified for the Vesta and installed.

2381: Computer system now operating at 60 percent of maximum. System expected to become self-aware within the year. Warpcore begins primary testing. Antimatter regulation control is found to be outside acceptable levels. Primary Magnetic containment malfunction found to be a problem. Stardrive section near completion with final attachment of secondary navigational deflector array. Bridge module attached to Primary hull.

2383: Warp Core passes Review Three and it tested to 85 percent peak. Computer system fully self-aware and umbilical from the station are cut as the ship become self-sufficient. Impulse systems pass Review Three and being autonomous low level power control. Secondary backup generators are shut down and become Auxiliary system control. USS Vesta leaves drydock for primary testing.

2383: USS Vesta goes to Utopia Planitia late in the year and Warp Stress Coating is applied. USS Vesta begins deep space assessments. USS Aventine construction completed.

USS Vesta returns to Utopia Fleet Yards for final exterior markings and paint. On 11, March 2383 the USS Vesta was officially commissioned by Starfleet during a brief ceremony.

### Tactical

Given that they are often weeks, months, or even years beyond reinforcements, the Vesta was defined with the teeth to be able to protect itself from nearly any threat, rivaling the Sovereign-class in this regard. All-around Type-XII phaser coverage is provided, along with two forward and two aft burst-fire torpedo launchers. Rather unusually for a large starship, she is also equipped with two forward-firing pulse phaser cannons, which can be used to great effect against clumsier vessels during combat. Considering that they are often so far from support, a Vesta-class ship must often be prepared not just to wound an enemy and then escape but to inflict sufficient damage to discourage further pursuit, though when she does manage to escape, there are nearly no threat vessels that could catch her.

Unlike a Sovereign, a Vesta is not meant to lead a column of starships into battle; her tactical abilities are geared towards self-defense and long-term sustainability, and so these vessels are rarely deployed in fleet engagements. As such, they have few to no command-and-control systems, apart from those necessary to control her small fleet of runabouts for exploratory missions. As such, she is still primarily an explorer, rather than a deep space tactical vessel, despite her armaments.
