Must space combat rely on guided missiles?

That depends on weapon performance and relative motion; claims that unguided projectiles cannot hit assume conditions that are not yet established.

The weapon mix depends on the propulsion and weapons available. Railgun targeting would involve the projectile's motion and the firing ship's motion, together with a prediction of where the target will be. A comparison that assumes the target always matches the projectile's speed leaves out slower movement, orbit, and other tactical conditions. Barrel durability is identified as a railgun problem, while future weapons remain too uncertain for a fixed prediction.
