UNSN Equipment


The UN Equipment is based on a modular design. This page outlines the modules but doesn't give explicit rules to avoid copyright infringement!.


A basic module aimed at absorbing damage at a minimal cost. UN Armour is a composite structure or (for some ground and asteroid based facilities) just rock. The Eiui are known to have more effective armour - it's just that the UN doesn't know how they build it.


Bays are used for carrying small craft aboard larger ships or ships aboard larger ships. The bays currently in service allow the launch and recovery of shuttles or the transport of ships.

The shuttle bays are not currently designed to allow the rapid re-armament of armed shuttles as the peaceful exploration of the universe didn't really envisage armed shuttles being needed. Ships with shuttle bays are currently bouy-layers, survey vessels, troop/colony transports or shuttle delivery vessels.

The ship-bays are installed on two types of vessel: Yard Tugs used for moving hulls about the various shipyards that the UN now has and Auxiliary Recovery Ships used for bringing disabled or heavily damaged vessels back from the front.

Cargo Holds & Magazines

The UN ships move cargo either in cheap open cargo holds (not particularly damage resistent and requiring port facilities) or more expensive partitioned/self-loading holds.

The Eiui have been seen to use specialist fuel-tankage.

The Military also have to move missiles in ready to use form - and that is where magazines come in. Similar to cargo holds, but able to feed their contents into the automatic reload systems of the weapons they serve.

Combat Information Centres

These complex modules allow a naval commander to better control the vessels in their location. To date, the UN has built static bases based on major planets, but has seen their mobile use by the Oskhoak who had one mounted on a ship.


Communications Modules and Datalink

While the bridge of each ship or station has some communications function, these system allow broadcast or tightbeam communications across considerable distance.

Broadcast systems have a shorter range than tightbeam ones but can contact elements where the exact position is unknown to the transmitter

Tightbeam systems have a longer range, and are difficult to intercept, but the transmitter has to know where the reciever will be when the message arrives and are thus less tactically useful.

Datalink is a ship to control and fire weapons from a whole group of vessels in a way that allows the salvo size to overwhelm the defences of the target.

Control Systems

Each ship requires some form of control systems with basic sensors, fire-control (if armed) and communications. The crew that operate the ship live here and they also have some ability to maintain the vessel and repair it if necessary.

Defence Systems

Close defence systems are used by the UN to intercept incoming missiles and (occasionally) shuttles. Major weapons systems can be given this task too, but they are generally more interested in damaging the enemy than protecting themselves.

The UN uses high-rate-of-fire beam based systems while the Oskhoak have been seen to use lower rate of fire missile systems. What the Eiui use is a mystery. 


Engines comes in various flavours that are fast in a pinch but slow strategically or faster strategically but no faster tactically. They rely on warping space so that a vessel has a pseudo-speed of a few percent of the speed of light.

Life Support & Accomodation

Transporting people requires considerable care as they have to have just the right atmosphere, temperature and need to be fed. This results in relatively large volumes of space having to be supplied aboard ship. As technology progressed, cryogenic pods have become available and the UN now moves most of its colonists this way. The live-transport is now reserved for Luxury Liners and Troops that need to deploy immediately.

Scanners & Sensors

Each planet or ship needs to know what is going on around it, and the Eyeball Mk1 is not good at doing this at distances measured in light-seconds unless the object being observed is a star or planet or moon. The ships bridge contains basic sensors, but for useful tactical (including combat) purposes these need to be enhanced by other modules.


A more expensive defence than the Armour noted above, but one that keeps damage away from the ships main hull and, unlike basic armour, allows the defence to regenerate over time.

Survey Systems

A vital component of any fleet, these allow the systems discovered to be checked for the existence of gateways to other systems, and the planets discovered to be surveyed for colonisation purposes.

Tractor Beams

The UN is fairly certain that a usable tractor beam is possible, based on the warp-space technology used in engines, but exactly how that can be done is still to be discovered.

Weapons: Beams

The US had a working laser beam system and China had a reasonable partical accelerator when space exploitation started and the UNSF was formed. Since then, the warp-space technology used in the engines has been developed into a third form of beam weapon system. The only problem with these weapons is thatthey have relatively short ranges and thus deploying them against longer range systems means running a gauntlet of fire to get close enough.

Weapons: Missiles & Torpedoes

The inventor that discovered the drive field found a version that produced a very fast version that tended to collapse after a few seconds destroying the engine in the process. Rather than abandoning the approach, he re-purposed it to deliver a warhead at long distance and the UN's Missile systems were born. These systems have several disadvantages when compared to the beams mentioned above: they can be intercepted or spoofed into going the wrong way; they run out of ammunition; and they cause less damage at close range.

Weapons: Shot

The concept of dropping rocks from orbit is one that the UN has grasped, but the slow speed of such weapons compared to that of other weapon systems has limited this class of weapon to that role within the UN.
