The Roadstead class Orbital Station is a large Space Station.

Description (Specifications)[edit]

The Orbital Station is a large commercial orbital facility found within systems in the Distant Fringe region. It is classified as an Orbital Complex. Similar designs have been in use from the time the Distant Fringe was first settled.

General Description & Deck Plans[edit]

  1. A basic plan of the station indicating the general layout and positioning of major elements.

The station is constructed as a close structure. It has four major elements - a cylindrical upper habitat, a central column, a large cylindrical primary habitat, and a cylindrical lower habitat. Eight commercial berthing arms project from the central column.

The central column has an overall height of 237 meters and a mean diameter diameter of 22 meters, and contains 75 decks of varying heights. The primary habitat has a diameter of 105 meters, a height of 35 meters and has 11 decks. Both the upper habitat and the lower habitat have diameters of 60 meters, heights of 25 meters, and each contains 8 decks. Each of the eight docking arms has a length of around 60 meters: one terminates in isolation and quarantine facilities. Some sections of the station are narrower and some are wider, giving it a total enclosed volume of approximately 472,500 cubic meters.

The main fuel tanks and the heavy machinery are located within the lower habitat. The main control center is located on the upper decks of the upper habitat and a secondary secondary control room is located close to the base of the central column, above engineering. The main cargo decks are located directly below the primary habitat and include the cryogenic (low berth) sections. General crew quarters are located within the upper part of the central column, though Stewards have rooms close to passenger accommodations and senior crew have accommodations close to the control centers. Second class accommodations are found within the less desirable central column while first class cabins occupy the outer part of the primary habitat, with windows offering spectacular views. The main commercial and leisure facilities lie at the core of the primary habitat and are focused on a multi-deck open plaza.

Basic Ship Characteristics[edit]

Following the Imperial Navy and IISS Universal Ship Profile and data, additional information is presented in the format shown here. The small craft factor indicates the number of squadrons (...of ten subcraft) carried on the ship. Tonnage on the universal ship profile is shown in kilotons (...thousands of tons) where necessary.

Basic Ship Characteristics [2]
No. Category Remarks
1. Tonnage / Hull The Orbital Station is constructed using a 35,000 dTon hull built in a close structure configuration. The hull is unstreamlined and cannot survive entry into a planetary atmosphere.
  • Individual sections of the station are divided by bulkhead walls.
  • There are multiple airlocks located around the station.
  • The complex is not capable of surface landings and risks catastrophic structural failure in significant gravity wells.
2. Crew Total Crew Complement: 379

Accommodations:
There are x3300 Staterooms.

  • x300 Staterooms are given over to crew quarters. Officers, senior staff, any celebrities working aboard the station, and the majority of the crew have individual cabins: the accommodations for junior staff are double occupancy.
  • Up to x1600 First Class guests may be carried: the stewards attend to their needs. However, staterooms located within less desirable sections of the station are generally available at Second Class rates.
  • The remaining x600 staterooms (a volume of approximately 2400 dTons) are fitted out as public plazas, malls and boutiques, entertainment complexes, casinos, spas and gymnasiums, restaurants, cafes, and other similar amenities.

There are x200 Low Berths. The low berths are overseen by the station's medical staff, assisted by properly trained service crew. These are most commonly used to store livestock but they may also be utilized by individuals wishing to wait out a period of time (most commonly for financial or tax reasons), or by those seeking medical procedures that may not be locally available or may require the arrival of a specialist. It is rare that the station's low berths are fully occupied.

Accessible areas of the hull are fitted with grav plates and inertial compensators and have full life support and environmental systems.

  • There are secure lockers with a total volume of 38 dTons. These include vaults, safety deposit boxes, and secure holding areas.
  • There are internal monitoring and security systems throughout the facility. Sections of the station can be isolated in the event of an emergency.
  • There are multiple Emergency Lockers.
3. Performance The station mounts a Maneuver half-drive, and a Power Plant-1, giving performance of 0.5-G acceleration (sufficient for orbital positioning only) and producing 450 Energy Points. The station does not have an agility rating. The dedicated internal fuel tankage gives the power plant 4 weeks duration.
  • The engineering section has a number of control rooms.
    • Ladders, gantries and platforms give access to the machinery.
4. Electronics Adjacent to the bridge is a Model/4 Computer: the station has x2 backup Model/4 Computers.
5. Hardpoints x350 hardpoints.
  • The listed battery groupings are considered standard for the station. Alternative battery groupings may be designated for specific situations.
6. Armament x5 100-Ton bays, mounting Heavy Missile Launchers.

x100 triple Beam Laser turrets, grouped into ten batteries of 10 linked turrets.

7. Defenses The hull is plated, braced and structurally reinforced, with an armor rating of 4.

x200 triple Sandcaster turrets, typically grouped into twenty batteries of 10 linked turrets.

The station is not fitted with screens or other passive defensive systems.

8. Craft The station is not supplied with intrinsic subcraft: these are purchased as required by the station's operators.

Hangars
There are multiple large enclosed hangars located around the station: the hangars have a total volume of 3,500 dTons and can be individually sealed.

9. Fuel Treatment The station has internal fuel tankage of 3,000 dTons.
10. Cost The basic cost of the station is MCr13,200.000
  • If multiple examples of the design are ordered all of the units in the production run qualify for a 20% discount, which reduces the price per unit to MCr10,560.000.
  • The station is a standard design. Detailed architectural plans are widely available and no design fee is chargeable.
11. Construction Time 176 weeks (44 months) as standard.
  • Build times can be reduced by mass production and the efficiencies such processes generate, by increased financing, and by allotting additional yard resources and facilities to the construction contract.
12. Comments Standard cargo capacity amounts to 10,200 dTons.
  • The cargo holds can be sealed and have independent life support and environmental systems.
  • Sections of the hold may be isolated if desired and can be provided with specialized environmental conditions, typically refrigeration.

History & Background (Dossier)[edit]

Roadstead class Orbital Stations are rugged and known for their excellent safety record. Many are finished to very high standards, offering services and facilities equivalent to surface hotels, leisure complexes and shopping malls, but with the additional benefit that they are free of any local taxes and surcharges. The design is representative and a large number of variants exist, particularly with regard to the allotted weapons systems, onboard electronics, and the fit out of internal spaces.

Support Craft[edit]

The station relies on a variety of support craft.

Distant Fringe Vessels[edit]

The Distant Fringe is said to be a far rimward-trailing area inhabited by colonists and refugees originating on Terra. The region is extremely isolated, lying hundreds of parsecs from the rest of Charted Space and separated from it by almost uncrossable rifts that were once broached by a system of calibration Points and the use of tankers. Those few academics within Charted Space who have found references to the Distant Fringe regard it as little more than a tall tale. Likewise, many of the inhabitants of the Distant Fringe believe the existence of Charted Space to be mythical.[3]

Vessels originating within the Distant Fringe are very rarely encountered outside of the region. However, misjumps do occur and anomalies with bizarre spacetime and Jumpspace effects exist: as such, craft of this type are not entirely unknown within Charted Space. Data about stations and facilities may be known from records found aboard such far-flung craft.[4]

Class Naming Practice/s & Peculiarities[edit]

A number of companies manufacture facilities equivalent to the Roadstead class Station.

They vary in hull shape and internal layout but all share the same basic design and all have very similar capabilities and performance characteristics

  • Each variant class of orbital station is named by the company that produces it: these organizations generally draw on traditional naming protocols. It is not uncommon for a historical class name to be reused.
  • Individual stations within a class are issued specific designations.
