This is a Warship I designed for an adventure of my group. Flight Configuration: https://dl.dropbox.com/u/7142719/EP%20Warship/Flight%20Configuration.png Combat Configuration: https://dl.dropbox.com/u/7142719/EP%20Warship/Combat%20Configuration.png All files (with Interior): https://dl.dropbox.com/u/7142719/EP%20Warship/Eclipse%20Phase%20Warship.rar It is largely based upon a fusion-drive freighter which a friend of mine an me made up (picture of unfinished model: https://dl.dropbox.com/u/7142719/EP%20Warship/Shinseikatsu.png). The Freighter was based upon this NASA paper (http://de.scribd.com/doc/31526947/TM-2005-213559). Also I presume warfare in the style Arenamontanus describes in his (sadly unfinished) paper (http://www.eclipsephase.com/comment/18698#comment-18698). I might have gotten some things wrong though, more on my take on how it works later. Finally, the overall layout of the spacecraft was inspired by the ISV Venture Star from Avatar. SPACECRAFT DATA: General: Propulsion Type: Antimatter Propellant: Metallic Hydrogen Length: 767.5m Mass: Ship mass (dry): 3005 metric tons Nominal Payload: 10000 metric tons Propellant mass: 8800 metric tons Propellant Density: 0.6t/m³ Four spherical propellant Tanks, radius: 15m Overall mass (fully loaded and fueled): 21805 t Drive characteristics: Magnetic Nozzle Power: 949 GW Exhaust velocity / Specific Impulse: 1000km/s DeltaV: 500km/s +16km/s reserve Thrust: 1897kN Effective Thrust (due to angled engines): 1783kN Initial acceleration: 0,00826g Reactor, Power plant and Cooling: Overall Power: 1165 GW Required Electrical Power: 583MW Actual Electrical Power: 623MW Thermal Power: 1247MW Low temperature Radiators (13m x 39m): 8 High temperature Radiator: (13m x 39m): 32 I recently read the Space naval combat again and it seems to me that the following does not conflict with it too much. Also, several ideas I had are there as well so they might not be terribly wrong. If you think something about the ship or how it works is wrong or implausible, please write a comment. How it is supposed to work: The spacecraft travels as shown in the picture “Flight Configuration”. When it there is no way for one of the ships (or fleets) to avoid entering combat ranges it shuts off its main engines and retracts the radiators along the truss into their storage areas and starts to cool down by venting coolant. As soon as the asset containers are cold enough they are accelerated along the truss onto careful selected trajectories in order to form a cloud of platforms several thousand kilometers away from the spacecraft and towards the enemy. Then the truss also gets retracted into the front section and the folded armor seals the last gaps, the ship now looks like shown in “Combat Configuration”. Due to the low temperature and the special materials used in the containers their position may not be measured precise enough to guarantee a first time hit. Also a large percentage of them might be Decoys. So the first time someone opens fire or uses an active sensor to identify an asset all hell breaks loose as every object that does something can almost immediately be identified and destroyed with near certainty. Probably only one side has some weapons left after the clouds have met and they will try to get a firing solution for the enemy ship, but maybe it can defend itself and get away. Of course the ship may have been in range before one faction has been eliminated in the cloud. The surviving ships float out of combat range and maneuver to catch the reusable assets, probably plotting a course for a rearming and refueling station. Any repairs are only minor because almost every hit deals catastrophic damage and disables the ship or severely limits the possible course corrections. The armor mostly serves to keep kinetic projectiles above a certain size and therefore makes it possible to dodge or intercept them. It also protects against ‘scorching’ by lasers that put their energy into a big area to hit the ship more easily and fry the sensor systems. I have a half-finished game to represent EP space combat that started as a card game like the one Arenamontanus dreamed up (see the thread where his paper is). Now it’s more like small coin sized chips and needs something more usable than scraps of papers with “laser” written on it, but the few games we tried where quite fun and surprisingly tactical. Of course more balancing is needed and the game instructions are probably pretty hard to understand, especially considering that they are written in German. But at the moment I don’t have time for finishing it.
