There are pipes and works out where they can be fixed with ease on a mill ship but civilian ships are all hidden. Then there are the transport ships. They are long spindles with cargo pods hanging all along them. Sort of like a tree look with nothing but metal webbing between.

	+ + Command centers will be VR goggle based. I always thought that the argument about needing real buttons to push for feedback was valid. I see the control room as looking like a bunch of seats that are good for high G maneuvers with each person sitting in one and having lots of buttons and panels in front of them. The VR would project what is needed as needed. The advantage of the goggles being the level of 3d interaction that can be had. + + For example, if one needed, one could be outside looking down on the ship to see damage or they could be in a 360 sphere looking at the battle or they could move to be outside the sphere view and get that perspective or they could be more just in the room with the other people looking at your control panels with info projected there. Just more versatile and not having it. You can also plug in from anywhere in the ship and take a look at what is happening by having the view you need patched in to you from control central.

Once distance a ship can change it's position by (from what it'd have if it cut power) at max accelerate during the speed of light lag from last known position to arrival of weapons fire exceeds the maximum"radius" of the ship by a significant amount, it can't be hit with a light speed weapon except by sheer luck.

Projectile weapons are also used to hit things planet side with great effect. These weapons are mostly chemically projected or else the use rail guns. The mass of a projectile is almost unlimited as is the speed but each is limited by the gun design. Many guns can fire at very high rates to cover a large area with rounds. This can be very effective at cutting out an approach vector but has a high cost in terms of the price of the bullets and storage area for them. Large amounts can also make ships mass become extream. This can be seen in the class of ships that area made to screen fleets.	+ 4.3 Projectile weapons. These have unlimited range and maintain full damage at any range.

	+ === Windows === + Spaceships do not have windows. Windows would allow lights that are to bright or lasers to enter the ship. They also make for weak points in the hull. For seeing outside the ship all people on board have 3d viewers that they can use. These views give better views that you could get from any window.

They shoot around 1,000,000 rounds a minute for most of these. They use rail guns or chemical propellants. Some also have terminal guidance packages and are almost missiles. They are very effective against a large range of targets but are costly to fire. Bullets also have the advantage of infinite range and a no reduction of damage with range.

These are just sensors set to see in different spectrum. The computer takes images from each sensor and attempts to create a complete picture of what is happening around the ship. Sensors can be blinded or fooled, or fail to receive any signal at all depending on the enemies counter measures. + 7. Computer AI to out smart the enemy. Smarter computers have better tactics and can coordinate more ships and weapons at the same time. Mostly this is relavant only when one starts to become damaged or else one Tech level is much higher than another. Bigger computers cost more but can do more. + 8. Electronic warfare devices to confound the enemies equipment. These devices come online when everyone has seen everyone else. These devices attempt to fill the spectrum with noise, overload enemy sensors or else lie to them about what is coming or who owns it.

- 5. Stealth Technology to prevent detection. - absorb, redirect or hide behind, make it flow over you.	+ 5. Stealth Technology to prevent detection. Although this covers the full spectrum from heat to high energy particles, it is most easy to understand by thinking of it as simple light. + 5.1 Absorb, these are materials on the ship or sprayed from the ship that absorb light. The obvious problem is that it will make a black spot in space with no stars or it will not absorb all frequencies. This leads to a war of detectors VS absorbers. Sometimes a ship can have a projector on the surface to make it look like there are stars there but it is hard to do this at all frequencies. + 5.2 Redirect; this works best for active systems like radar. The radar bonces off the target but does not get back to the receiver and thus is not detected. It can be overcome by having receivers in places that signal is reflected to. + 5.3 Hide behind; You can hide behind a comet or meteor or a planet or even a sun. You might be able to make a small cloud to hide behind but most systems will monitor all of space and thus will know something is different. + 5.4 Make it flow over you. These coatings can take the radiation around them and bend it so that it flows around the ship as if it were not there at all. This would be prefect except that a perfect coating has not been found. Some are very good though at high tech levels.

These systems might include, cooling, heating, light, atmosphere, or even a spinning ship section to simulate high G or low G as needed. At 1 G this section would be large, about 900 meter in radius for a happy human but then there would still be acceleration to mess that up. + + The ship can be fitted to take standard cargo pods also. Normal pots must use 10% of their volume for structure in a normal 1G ship, more for extras. A standard cargo pod is, 12 metres x 2.4 x 2.6 for historical reasons. High tech pods can navigate and reenter by themselves, under computer control, when in communication with ground flight controllers. They have very limited thrusters that are only good for one reentry before needing a recharge. More low tech or fragile cargos must be taken down with a tug or other spaceship. Some freight is beamed down but the costs for this are very high. + + Pod Ships Capacity is measured in 12m equivalent unit (TEU), the number of standard 12-metre containers measuring 12.2 × 2.4 × 2.6 metres (40 × 8.0 × 8.5 feet) a vessel can carry.

- === Computers ===	+ === Computers and Controls=== + + All systems are controlled by onboard and central computer systems and coordinated by a central (usually redundant) computer. Each system's controller typically has its own interface for use by local crew members. The bridge has stations for controlling all the various systems and providing diagnostics. Connecting the various systems are electrical or fiber optic wiring running throughout the ship inside the exterior hull. The precise nature of the control runs, controllers and computers are dependent on tech year, but basically require (insert percentage here) of the hull devoted to this infrastructure (perhaps a higher percentage as tech gets lower). + + The number of crew required to operate a ship is heavily dependent on the sophistication (read cost) of the control system installed. The likelihood of a system being damaged is based more on the redudancy of the system (read volume consumed). The number of crew required to maintain such systems is a function of volume. + + Workstations for individual crew may be more or less capable depending on tech year and cost. Military vessels tend to have more capable workstations, and more of them, while commercial vessels have fewer complicated workstations serving more functions, but sacrificing some of the "information overload" protections of more sophisticated military controls. Commercial vessels tend to have fewer crew for the same tonnage but are less capable in an emergency. + + [Peter Brenton, pbrenton@mit.edu]

	+ + === Hard Points and other external components === + Hard points are places in the hull that have the electronics and structure to support weapons. The amount of hard points is based on the surface area of the ship. Each hard point takes about 2x2 square meters and internally take up 3x3x3 cubed meters. Note that weapons systems may take up an additional volume and also make take more than one hard point combined. They costs X per point. + + A ship must have doors. These take up area also. All ships must have door that will let people escape in any case that the ship may encounter. These doors are airlocks and take up 2x3 meters of surface area and 3x4x5 meters of internal volume. These cost X per door.
