	+ + 1 light-second is probably the limit, depending on ruleset. Even 1 + light second and stipulating you can fire whenever you want to, a 1g + ship can move at least 20m and a 6g ship 120m. In terms of locus of + target locations, that is 40m and 240m respectively. + + I suppose that won't get your hugest ships (in their big dimension) + out of the line of fire, but it'll move a lot of smaller ships out of + the way sufficiently to have a shot miss. I suspect hundred to + thousands of ton shipping can reasonably dodge and 100K dTons+ just + can't. The 10-100K range might be possible depending on design.

	+ + SHIP FIGHTING + Scout Courier length? I'm guessing about 30m? Width maybe about 20m? Height 10m? + + If you can modify your location by that distance in the time lag from + sensor reflection being generated to incoming beam arriving (so, say + 3x the distance between the target ship and the firing ship plus some + analysis/tracking lag), then you can in fact dodge the single shot. + (this is largely why that isn't how it will end up being done) + + 1G for 1s = 5 m + 1G for 2s = 20m + 1G for 3s = 45m + + Assuming the hits were to be dead center, you need to move by 15m in + the long axis, about 10m in the wide axis, and 2.5m in the height + axis. Notice how little effort and how low the Gs involved are. Since + the time you are worried about is 3x the distance, to get a 45m + movement, you only need 1 light second of separation. And if you count + that as 45m in any direction, that means your locus of targets just + went to 90m width in any cross section. + + Bigger ships and higher Gs should produce results that still make + agility feasible in the 3-4 light seconds real ranges. The hugest + ships might need 7-8 seconds assuming mediocre Gs. + + Remember, unless you're firing on passives (which only have 'emitter + (target) to shooter' + 'analyze/track lag' + 'shooter to emitting + target' distances), then you've got to add in an addition first stage + of 'shooting ship to target' for the outgoing sensor wave. That's 3x + the distance between. That adds up faster than you'd think. + + For instance, a 3G ship at 3 real seconds = 1215m (or double that + since you could go any direction). So a locus of possible target + locations spanning a sphere of diameter 1215 m. That's with a zero + analysis/tracking lag. + + That's enough to miss in the 'few shots' or 'single shot' model.

	+ + + Great advanced ship design thoughts by someone on TML. + + And if you run the big plant at full tilt all the time, where's the excess + power go? + + This is one of the conundrums with the Traveller drives. It should take a + hefty chunk of a ship's power to generate thrust (I forget if it actually + does, but it should) with M-drives. J-drives are their own insanity, but + they have mass capacitor banks that are charged then discharged. Charging + may take some time too. + + So if I have a plant capable of a high output to charge a jump drive and to + support high G thrust and to drive weapons, it had better be something I can + turn off (and the only way to do this is the variety of different actual + plants that constitute the single logical plant) parts of when I don't need + that power. But in those cases, how do you get it up fast enough in some + situations? + + I think this sort of multiplant situation explains why it takes a ship some + notable time to come from a low alert status to a high alert status - the + bringing live of the power systems to drive the combat systems (as well as + time for people to get suited and reach duty stations, strap in, etc). It + also means that ships going into areas they expect combat will have the + entirety of their power plant system online and will be generating more + energy than they need for some period of time (I think this is where they + charge up some batteries, which they later make sure to exhaust once they're + out of a combat situation or during particularly high energy demands during + combat). + + I think this sort of conjuration of how power plants function introduces a + number of interesting in-game effects and decisions for how to handle your + ship. They are largely obscured by the fleet combat systems, but I assume on + individual ships, commanders and engineers work to make these decisions as + necessary and to keep the ship's energy balance (supply vs. need) as close + to even as possible. The times when there is a disparity will be the + interesting times....

	+ + This bit is by Tim, Timothy Little, from the public TML listserv + + "So a highly effective drive implies extremely high density of energy + storage and ability to turn that into useful work. For example, a + drive that can thrust at 6g for 3 days implies at least 10^14 J/kg + energy storage, and safely handling power densities on the order of + 1000 MW per kilogram of vehicle. This is regardless of whether it's a + reaction drive or not, or how hot it can run. + + The former criterion can be met by the availability of efficient H-H + fusion, though without much leeway. The latter requirement makes + things rather interesting. A 1000-tonne craft thus must have the + ability to deliver 10^15 W on demand. That's the yield of a fairly + large nuclear detonation per second, and the vehicle must be able to + sustain that sort of output for days."

- - I have been playing with the idea of having for the first year the fastest ship being jump one. Ships can have jumps that are partial levels. This would force communtiy and trade of a certain level. Then when jump 2 is invented you will have back waters joining together and start to get a real feel of politics and something to really war about. It's just and idea but I think it is an intriguing one.	+ Jump one is one parsec or 3.262 light years. + The basic game area is 60x60x60 parsecs, thus you can jump from one side to the other in 60 jump one jumps if there were a straight line of stars. Travel time would be from the outer jump Beacon to the Inner Jump Beacon for each jump plus jump compute and jump charging time. + I have been playing with the idea of having for the first year the fastest ship being jump one. Ships can have jumps that are partial levels. This would force community and trade of a certain level.
