So I was doing some calculations about intra system flight.
A ship with speed of 10 VU, flies about 200,00 km/h which means a distance from earth to moon would be covered within 2 hours. With some orders its possible to do it in one hour. Eldar ships could pull it off in half hour.
This is of course battle speed, with manouvers etc. In Stars of Iniquity it says, that travel to the edges of solar system takes about 2 week for an avarage system. As a edge, for safe jump I estimated about 100 AU, which means far beyond kuipers belt. To get there in two weeks a ship would have to have speed of 0,041 c, which is about 12,400 km/s. With this speed the distance to the moon would be covered in 30s.
What this means.
Do ships really have to fly for two weeks to make a safe warp transition? Why? Warp is warp, real space gravity, shouldnt affect this?
ANY relief fleet would take about a month to get whenever they need too. Lets say a fleet that is only a week of warp travel away, takes two weeks to get to jump point, and then another two to get to the planet. So 5 weeks.
In novels and games everything takes much less time, otherwise it would be reaally boring. I know it makes sense, but that prevents keeping action on high pace. Heroic last minute rescues, etc.Thats also why, I'm not a fan of one strategic turn lasting 30 minutes of real time.
"Fire the guns! And now its time for a cup of tea. They won't fire on us for the next half hour, so how about a quick ping-pong match?"
Also not a fan of hundreds of people turning cogs and moving gigantic shells. Its just so stupid, and pointless. In grimm darkness of far future their is only boredom of space, and huge inefficency.
