Rail guns are what the navy is going to use to replace cruise missiles
Realistically, the Navy uses cruise missiles to hit long range targets that are beyond line of sight (usually ~10mi due to curvature of the Earth). While scientists may be able to come up with targeting systems that make extremely high velocity projectiles accurate beyond line of sight, it is highly unlikely that the Navy would retire such a versatile offensive weapon for one that seems very limited in capabilities... (A cruise missile can hit a target on the other side of a mountain, let's see you figure out how to do that with a weapon designed to be fired in a straight line..)
More likely to replace the 5"
