The most common Pre-Contact warship attack was the equivalent of David throwing a rock at Goliath. Warships used electromagnetic rail guns, or the older exploding shells of autocannons and machineguns, to fling projectiles at the enemy. Even with rudimentary guidance modules and maneuvering thrusters, warships could easily carry a thousand projectiles of various common sizes for any one rocket. And while the individual launchers were larger than a rocket launcher, the ability to fire more than once is a decided advantage when engaged in prolonged combat.
