The Sentinel class Missile Platform is a satellite.

Description (Specifications)[edit]

The Missile Platform is designed to be a highly survivable orbital weapons platform. Although it is primarily a defense installation, it serves in a secondary role as a communications relay. Its powerful onboard sensor array may occasionally be used as a scientific observatory, typically monitoring weather patterns and stellar conditions. Similar designs have been in use from the time the Distant Fringe was first settled.

  • The platform is a TL-11 design.

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. [1]

Basic Ship Characteristics [2]
No. Category Remarks
1. Tonnage / Hull The Missile Platform is constructed using a 30 dTon hull built in a generally cylindrical configuration. The hull is partially streamlined, giving a relatively limited atmospheric performance that is reliant on its onboard gravitic systems: the structure rarely leaves its orbital position.
  • Individual sections of the platform are divided by bulkhead walls.
  • There is one airlock, giving access to the operations section. Armored doors give access to the missile loading bay.
  • The platform has sturdy retractable legs, allowing it to stand on level surfaces such as decks.
2. Crew Total Crew Complement: 0 (...the Platform is automated).

A cramped operations compartment contains facilities for 2 maintenance technicians. Such personnel carry out occasional duties such as refueling, routine maintenance, refreshing onboard supplies, applying software updates and hardware upgrades, and downloading collected data.

  • Gunnery crews may occasionally be stationed aboard the platform. This is an unpopular duty.

x2 Small Staterooms.

  • These are provided for use by maintenance or gunnery crews.

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

  • There are internal monitoring and security systems throughout the platform.
  • There are x2 emergency lockers.
3. Performance The platform mounts a Maneuver-1 drive and a Power Plant-4, giving performance of up to 1-G acceleration (though generally the drives are only used for orbital positioning) and producing 1.2 Energy Points. The Platform has an agility rating of 0 and an emergency agility of 1. The internal fuel tankage gives the power plant 7 weeks duration at full combat output: the platform generally operates in a reduced power mode, increasing its endurance exponentially.
  • The engineering section is controlled by the computer or from the operations compartment. Access to the machinery can be gained via a pressure-tight hatch.
4. Electronics The operations compartment contains x2 acceleration couches and control equipment. The platform is run by a largely autonomous Model/3fib Computer: no backup computer is installed.
  • There are multiple control points throughout the platform.
  • The platform is fitted with communications equipment and an advanced sensor array.
    • More sensitive instruments, such as the neutrino sensors, are mounted on a long boom to hold them clear of the platform and any potential interference that it may generate. Other sensor systems are mounted internally, protected by the hull.
    • It is fitted with backup commo and sensor systems.
  • It is equipped with an ECM package and Jamming Equipment.
  • It has a transponder unit that can be deactivated on command.
5. Hardpoints 1 hardpoint.
6. Armament The normal weapons fit-out for a Missile Platform is:

x1 triple Missile turret, forming its own battery. These are operated by the onboard computer as necessary.

7. Defenses The hull is heavily plated and structurally reinforced, giving it an armor rating of 11.

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

8. Craft The platform carries no subcraft.
9. Fuel Treatment The platform has internal fuel tankage of 2 dTons.
10. Cost The basic cost of the platform is MCr60.570.
  • The platform is a standard design. Detailed architectural plans are widely available and no design fee is chargeable.
  • If multiple examples of the design are ordered all of the platforms in the production run qualify for a 20% discount, which reduces the price of each unit to MCr48.456.
11. Construction Time 24 weeks (5.5 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 The platform includes an armored missile magazine with a capacity of 1 dTon.

The Missile Platform is operated by an autonomous Model/3fib Computer. It relies in its advanced sensors and threat analysis algorithms to assess potential dangers and deal with them accordingly.

  • The platform is capable of locking itself down in an emergency.
  • The operations compartment and engineering section may not be accessed without the appropriate protocols and security clearances.

History & Background (Dossier)[edit]

The Missile Platform is representative of designs used throughout the Distant Fringe. While it is relatively expensive, it is extremely rugged and durable. Large numbers of variants exist, particularly with regard to the allotted missile complement and the onboard electronics.

  • Missile Platforms are generally deployed in small groups, relaying data between each unit.

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 weapons platforms equivalent to the Sentinel class. 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 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 examples of the class are issued specific serial numbers and transponder codes.
