Hello everybody, a not-quite-random thought: VE187 has a short paragraph on gunfire in space. Those rules seem to assume a deep space engagement, with a low relative velocity between the vessels, at least compared to the unspecified muzzle velocity.
What happens in orbit, and with muzzle velocities lower than the escape velocity? * Firing a gun means the projectile makes an orbit change, with all the delta-V expended in a fraction of a second. * This new orbit might intersect with the surface of the planet, and with proper calculations it should be possible to hit a ground target. The impact could come hours or days after firing. * Alternatively, the new orbit would be stable as well, but it happens to be on a collision course with another orbital object. Did I get the physics right? Are there rules in 3E GURPS? What are they? The indirect fire rules and the space fire rules appear incompatible, unless I'm missing something.
