maneuver drive limits

[Matt Wilson]

I’d be more inclined to put a speed limit on mdrive, can’t accel past X c in 1000D grav fields.

Unless I botched the math, you can get to Neptune in two weeks at ~1% C. Doesn't seem too restrictive to me as a cap.

Re the frac c jump kamikaze, doesn’t require the 1000D fix, the jump limits requiring 0 vee to initiate or vee to 0 after jump will do.

I’d be more inclined to put a speed limit on mdrive, can’t accel past X c in 1000D grav fields. But that works more for me since I treat m drive as a partial warp bubble/floater decrease ship weight to kgs thing.

or coming out of jump your vector *may* not be aligned. which is why most ships drop to 0 vee when jumping.

though not in the rules other than maintaining velocity, I could see a 1d6 roll to determine direction (hex-based, adjust to suit for 3D and all that) of vector out of jump. Since the time is +/- 10% or so, the vector may be different as well.

From what I see you're going to have to come out of Jump at a very particular location to have a chance of hitting the target. In this case "target" means somewhere on the entire planet. There's going to be a good bit of variability built into the whole thing due to the variability of the jump window. The planet will rotate 1 1/4 times during the jump emergence window, so jumping a rock in and hitting a particular city is highly unlikely. Your best chances of hitting the planet will emerging either slightly ahead of or behind the planet's orbit, Emerging Above, Below, Sunward or Starward from the planet is pretty much a guaranteed miss. Even then the 100d limit means you will be about 3x the distance to the moon away. Because your point of emergence is tightly constrained the defenders know exactly where to watch for an attack.

And if as Coliver says, your vector coming out of jump varies by more than a few degees you are no going to have time to adjust.

Yes, it's a very fast attack, probably a minute or less warning, but they know exactly where it must come from. That makes defense alot easier.
