Alexandria II class

The Alexandria II-class was designed by Starfleet as a deep space station that would provide it with the capability to maintain a base of operations in the furthest limits of known space.

Background
Taking inspiration from the Nor-class Cardassian space station which later became known as Deep Space 9, Starfleet's Corps of Engineers designed and developed a deep space station that would not be as large and bulky as the older starbases and yet powerful enough to defend itself from hostile starships and roomy enough to encourage trade and commerce with other races fulfills the following important functions:
 * Science research – With its numerous and advanced sensor arrays, it serves as the stellar science research laboratory center of Starfleet in deep space.
 * Diplomacy – Through its full diplomatic facilities composed of embassy suites, diplomatic housing, mediation halls, and conference rooms, it serves as the diplomatic hub of the Federation in deep space.
 * Commerce and Trade – Through the Mall, the Central Market, the Park, the Bazaar and the four Concourses, the station plays host to over 1,000 business establishments.
 * Station Defense – The station has an arsenal of 48 Type-XII rotary-mounted pulse-phaser cannons, 48 Type-XII stationary-mounted phaser emitters, 12 Type-XII slide-mounted phaser emitters, and 48 torpedo launchers. The primary weapons feature of the station is the defense sail. The sails are placed at 30 degree intervals around the main platform’s dorsal and ventral sides and housed most of the tactical systems of the station, including Type XII phaser turrets, Type XII phaser arrays, rotary phaser cannons, torpedo launchers, and tractor beam emitters. These emplacements provided a nearly 360 degree sphere for defense, only interrupted by targets obscured at close range by the other platforms of the station. Each sail tower is armed with two torpedo launcher tubes, two rotary phaser cannons and one phaser turret. With this firepower, the Alexandria II station was a virtual floating fortress.

Station Layout
The station’s structure central core was a cylindrical structure consisting of seven terraced platforms containing various key facilities:

Command Platform – It is the top platform of the core. The Operations Center – or Ops, the subspace communications antennae, the deflector shield generators, 4 holodecks, a gymnasium, a mess lounge, the station’s commander’s office, four Starfleet wardrooms, the station offices of Task Force fleet officers, and quarters for station personnel were located.

Station Operations Platform – It is the platform below the Command Platform. It is connected to the Central Core by four crossover bridges. It is composed of three hubs: Main Platform – It is the platform below the Station Operations Section. It is the most populous and largest section of the station. The main platform is connected to the Central Core through five crossover bridges. It is divided into four sections: the Habitat Section, the Hydroponic Gardens, and the Main Docking Section, and the four Docking Spokes.
 * The Diplomatic Hub has full diplomatic facilities. It contained conference rooms, ambassadorial suites, and an arboretum. It is currently occupied by deputations from 15 different interstellar species including the Federation, the Klingons and the host Khronnians.
 * The Medical Hub is the primary medical facility of the Federation and Starfleet. It is manned by both Federation and Starfleet surgeons, physicians, nurses, medical researchers, and medical technicians who are all specialists in exobiology.
 * The Science Hub boasts of state of the art science and research labs and an Astrometrics Lab that is four times the size of those found on capital starships. It boasts of cutting-edge scientific equipment and serves as a test bed for experimental science.
 * Docking Hub 1, is located in the outer perimeter of the platform. It features seven retractable docking pylons exclusive for Federation and Starfleet capital ships. The Passenger Lounge Area and the Immigration and Customs Bays for Docking Hub 1 are found adjacent to it.
 * The Habitat Section occupies the upper half of the inner two-thirds portion of the main platform and is where many landmarks and facilities are found.
 * The Mall was a public area for commerce and recreation where a series of businesses and entertainment facilities operate. It features numerous lounges, holosuites, lecture halls, casinos, bars and hotels. The Mall also houses the Infirmary – the medical care facility of the station
 * Security Central is located inside the Mall. It is the headquarters of station security and for the numerous security precincts located throughout the station. The Assay Office is located beside Security Central
 * The Park is a large, natural area aboard the station featuring a cultivated woodland, swimming pools, a theatre, and other recreational areas.
 * The Central Market is home to many open bars, kiosks, cart vendors and small shops.
 * The Bazaar features shops and stalls carrying goods from both Alpha and Gamma Quadrants.
 * Station Housing is where the residences of most of the station’s 15,000 semi-permanent civilian population are located.

Main Hangar Section – It is the platform below the Main Section. It has parking and repair space for over a hundred shuttles and small starships. It also houses the station’s complement of Valkyrie class fighters. A replimat, the Passenger Lounge Area and the Immigration and Customs Bays for Docking Hub for Main Hangar Section are found adjacent to it.
 * The Hydroponics Gardens occupies the lower half of the inner two-thirds portion of the main platform and is where hydroponic crops are grown for station consumption.
 * The Main Docking Section is located in the outer third portion of the station’s main platform and is used for starship docking facilities and moving and storing cargo. Located adjacent to the Main Docking Section are the Main Passenger Lounge Area and the Immigration and Customs Bays. It is the first stop for station visitors and the last stop for those departing. Adjacent to these are the Impound Lots. 48 docking ports are distributed around the perimeter of the station’s hull to accommodate medium sized starships, while its 48 landing pads are distributed on the upper hull, each able to accommodate two runabout-type starships. Sensor arrays, shield generators and weapons ports are also found along the outer hull of the main platform. The Docking Control Room, located near the center of the platform serves as the nerve center of the Main Docking Section, the Main Hangar Bay, Docking Hub 1 and Docking Hub 2.
 * Docking Spokes One to Four are part of the Main Docking Section and are the platform’s main feature. Each Docking Spoke is 2 kilometers long. Each Docking Spoke has: 1) full port of call facilities for 24 medium sized starships, 2) a Concourse, which is a public area for commerce and recreation where a series of businesses and entertainment facilities operate, 3) temporary living quarters for the crew of visiting starships, 4) full ship repair facilities.

Spacedock Section – It is the platform below the Main Hangar Section and is composed of seven full sized spacedock cages capable of starship construction, refitting and maintenance layovers. Spacedock Control Room serves as the nerve center of the Section. Spacedock Engineering with its maintenance and repair bays are also located in the inner ring of this section.

Docking Hub 2 – It is the platform below Spacedock Section and features seven retractable docking pylons for non-Federation capital ships. It has its own Passenger Lounge Area, Immigration and Customs Bays, and temporary residential accommodations for visiting crew.

Main Engineering Section – It is found on the lowermost platform of the station. Its primary purpose is to be the central point for control of all engineering systems, especially those relating to power generation. The section also contains Engineering Labs, life support, manufacturing and maintenance facilities, industrial replicators, and the Main Computer Core.

Below the Engineering Section is the Matter Antimatter Reaction Chamber also known as the Power Core, which is located within the stations inverted dome at the bottom of the Central Core.
