There was another use for Pre-Contact projectiles. A particularly ruthless warship commander could stay outside conventional rocket range and fire the projectiles at stationary targets. Planets or space stations are examples of this. Accuracy was the common problem of these “bombardment” tactics though, and “accidentally” blowing up a civilian compound was a particularly bad way to get oneself declared persona non grata from any civilized star system. Therefore the most effective tactic against prepared planetary defenses was also the most dangerous to use as it was never officially sanctioned by any major government.
