Atlantis Class City-Ship

The Atlantis Class City-Ship was not made or designed by Starfleet Command, the Federation, or anyone in known space. The craft / city has been seen on a small number of occasions, however. It was evidently designed and built by a humanoid race from an alternate version of reality. There is a fair amount of controversy over this theory, though most reputable scientists agree that this is a reasonable explanation for its existence.

Layout

City Layout

The city-ship is laid out to be a floating city upon the ocean of a planet. The central core of the city is where most of the services, residences, offices, and laboratories are located. This is a densely constructed area. There are then 6 peninsula structures come out from the center for various other functions. This includes landing space for auxiliary craft, recreational services, defensive and offensive systems.

Central Tower

Central Tower

At the heart of the city is a 70-story tall central tower, also called the central spire. This contains the main command and control room for the entire city as well as the city's gate room and a landing bay for Puddle Jumper Class Shuttle, which houses about 20 shuttles. This is designed for these vessels to come into the gate room itself for gate-travel or to exit the city via the top of the tower.

Adaptations for Use

Since the power source of a Zero-Point Module has not been completely figured out by current science, nor is the substance called Naquida known to science at this time, the city's power systems can be adapted to use fusion reactors to replace the Naquida reactors and either a singularity core or matter/antimatter reactor to replace each of the 3 ZPM's which power the city. This adds fuel storage and appropriate safety systems to the city.

Computer / Control Interface

In addition since many of the computer interfaces were designed for telepathic or other mental control methods, significant adaptations have been made to the control systems for the city-ship. The control room, power room, and other key areas have been heavily retrofitted to provide touch control interface terminals. This is also the case throughout the cities hallways and holographic emitters have been installed throughout the entire city. These emitters will also augment the retrofitted control interfaces. Several Multinodal Cores have been installed as well and a high output ODN has also been retrofitted throughout the station with bioneural and isolinear circuit paths. While the city has a very effective communications network, these systems augment that network and allow for easier interfacing with Solas Tempus, Federation, Vulcan, and other Alpha/Beta quadrant species.

Defensive / Offensive Systems

While the city-ship is designed with the Ancient Drone weapons and those weapons are extremely versatile Solas Tempus has not entirely been able to replicate this technology. As such the city-ship weaponry has been augmented with 12 variable warhead torpedo launchers (4 at each of the 3 drone launch sites). In addition the tower has been equipped with a pair of high output phaser beam emitters while strategic locations throughout the city have been outfit with both point defense and pulse / beam phaser turrets.

The Lantean Shield system is extremely effective, as a secondary system to augment that shield the city has been equipped with a deflector shield grid. This grid is capable of operating both in space as well as on the ocean.

OOC Notes

There are some serious scaling issues with canon within Stargate Atlantis and how big the city is. It is noted that it has roughly the same amount of area to explore as Manhattan, this is problematic with on-screen promotions of the city. It is also noted, within canon, that the central tower is 70 stories tall. At the same time the Daedalus is seen landed at Atlantis (200 or so meters long) and being very small in comparison. Several theories have been given to how large the city is, but we've settled on 8.5km based on the surface area of the island of Manhattan as a starting point.
