For ur information, the AIF has kenetic kill rods. At orbital reentry speeds, shape of a projectile does not matter, as it'll disintegrate either way on impact. Mass and wind resistance is basically all that matters, and because the tungsten slightly melts while falling down, it already provides that ability, and it has a lot of mass, so it'll already provide a big explosion on impact(about the size of a 15kt bomb for most of them). And as stated before, just about any weapon can be used for orbital bombardment. Now, for surface ship use, u may as well forget about using projectiles of any sort on such a target, as only the force of the burning gunpower is used to fire the projectile, and you'd need an absurdly large gun in order to put any sizeable dent into a mountain.

Um, 0.2 x the speed of light would be highly..... Impractical. Espially in the atmosphere, as basically any projectile fired at that speed would instantly evaporate, in the barrel. It wouldn't even be able to reach that speed regardless, the max that may be possible is MAYBE Mach 15-17 if your lucky, and even at that speed, tungsten will soften drastically, making use of it against aircraft improbable, as the only thing that could do any damage to said aircraft is the kenetic energy, which due to the soften metal, will likely just splatter on the aircraft or bounce off entirely. And AIF doesn't even have the nessecary tech to get rail gun rounds to fire at Mach 20, much less 0.2 the speed of light.

MAC= very large coil gun(or just coil gun in general)

Well, then your going to have a few problems. For one, because you don't have a canister to keep the bullets straight while in the barrel(nor anything to SURVIVE the acceleration), the spread will be ridiculously large, And you may be lucky if ONE pellet hits the intended target/s. Second, rail guns need direct contact with the round to impart velocity. Considering the types of rounds your going to use, that will be very hard to get to that 0.4 light mark. Refer to the paragraph on the FCS for most of the reasons. The only way to potentially do it is to have a tungsten 'wad'. Which will be need to be light, as otherwise the acceleration will be too slow, but also thick enough to not get destroyed upon acceleration by the shot. And as stated before, this is only practical in space or planets with little to no atmosphere(EG Mercury), and most of AIF's territory is on earth or planets with plenty of atmosphere.
