For a gaming/writing project loosely using Traveller rules but set in
the Ron Moore BSG universe, I've developed a couple of bombardment ships
that were designed to use rather large kinetic darts to strike surface
targets and possibly have a limited anti ship (if it's in orbit)
capability. Where I'm having trouble is coming up with a ballpark for
their mass. I'm thinking with the numerous solar systems to mine, that
tungsten would be the best option...but I am open to suggestions. Once
the material is known, the next step is to figure out a mass and these
two steps are where I need some help. The two darts' specs are located here:
