Presidio class

## SPACECRAFT CLASS

The ***Presidio*-class** was a type of spacecraft developed by Starfleet in the early 25th century. It was designed as part of the C3 Development Project to serve in a command, control, and communications (C3) role.

## Description

The *Presidio*-class was designed to function as a mobile unit command center. Its advanced communications arrays were capable of relaying battle-critical information instantaneously and a dedicated computer core allowed for real-time processing of high amounts of tactical information. This was all interconnected in a unit command center (UCO), where leadership could use the full capabilities of the C3 cruiser when coordinating with other Starfleet and allied vessels.

## History

Following the end of the Last Federation-Klingon War and treaties between the United Federation of Planets, the Klingon Empire, and the Romulan Republic, joint operations were prioritized by Starfleet. Based on after-action reports, Starfleet Command tasked the Starfleet Corps of Engineers with creating a design to fill the need for a command, control, and communications starship to serve at the center of Starfleet units.

Starfleet engineers at the San Francisco Fleet Yards coordinated with their peers from the Klingon Defense Force and Romulan Republican Force to outline basic principles and functions of the desired C3 vessels. Unlike traditional development ventures, where only a single starship design was created, the C3 Development Project led to the design of three different classes simultaneously for each respective organization. The *Presidio*-class was the name given to Starfleet's more tactical-oriented design.

Entering service in 2410, the USS *Presidio*, prototype of the class, was immediately put on the front lines against the Iconian Empire. It served as the flagship of a cruiser group stationed in the Donatu sector.

## Technical specifications

### Physical arrangement

#### Deck plan

The following was the standard internal layout of *Presidio*-class vessels.

### Command systems

The unit command center (UCC) was located on Deck 1 in the primary hull.

Main engineering, including the chief engineer's office, was located on Deck 24 in the secondary hull.

### Propulsion systems

Equipped with a Rigel Labs X06 Quantum Slipstream Field Projector, the vessels could travel at slipstream speeds exceeding 300 light years per hour. Due to power limitations at the time, the drive could only be operated for 15 seconds before needing a 2 hour recovery downtime.

An Ithra IT-7 Transwarp Coil was standard on the class and allowed each starship to connect to the Federation Transwarp Network and jump to gateways within the network at speeds of 360,000 light years per hour. The drive had massive power needs, even more than the quantum slipstream drive. To power the coil, starships had to divert energy from weapon and shield systems. Due to strains on the system, it could only be used once every 20 hours.

### Tactical systems

The exterior hull of the class was an ablative neutronium alloy with duranium nanomesh coating. Three Yoyodyne 960-B unified field emitter deflector shield arrays provided the deflector shields.

The *Presidio*-class mounted 20 type-X Annular Confinement Beam-jacketed phaser arrays, 6 type-XII pulse phaser cannons, and 8 variable-payload Mk 110 launch tubes, four of which were turreted. Quantum torpedoes were carried as standard ordnance, but the *Presidio* also carried a complement of tricobalt devices for the bombardment of heavy targets.

Several varieties of automated platforms, which were equipped with phaser arrays and mine replicators, were standard equipment on the class. These platforms could be strategically placed to aid the cruiser and its entourage in combat and defense.

### Auxiliary craft systems

The four shuttlebays of the *Presidio*-class could accommodate up to 60 auxiliary craft, though the standard complement was 42.
