The Navy plans to fire 5-inch diameter non-explosive projectiles from deck-mounted railguns:
The Navy plans to fire a high-speed, long-range rail-gun Hypervelocity Projectile from its deck-mounted 5-inch guns to destroy enemy drones, ships, incoming missiles and even submarines, service officials said.
The effort is led by a special Future Naval Capability program.
Navy officials say the program is leveraging commercial electronics miniaturization and computational performance increases to develop a common guided projectile for use in current 5 inch guns and future high velocity gun systems. The HVP effort will seek to increase range and accuracy of the 5-Inch Gun Weapon System in support of multiple mission areas, service developers told Warrior.
Developed initially for an Electromagnetic Rail Gun next-generation weapon, The Hyper Velocity Projectile, or HVP, can travel at speeds up to 2,000 meters per second when fired from a Rail Gun, a speed which is about three times that of most existing weapons.
BAE Systems Hyper Velocity Projectile. 5-inch gun. Found at NBF.

Uhmmm, in case you need help with your reading comprehension, this isn't about shooting a railgun.
Its about shooting a sabot jacketed projectile out of a 5 inch gun with the same (or similar) powder charge that they fire conventional shells.
They aren't converting these guns to rail guns, they aren't going to shoot anything all that much faster out of the barrel than they already shoot, (beyond the speed improvement they would get by firing a lite weight projectile).
Its no more barrel wear, and because its a sabot round (google that) your don't even have to engage the refiling in the tube with anything except plastic, the projectile has its own fins for spin and stabilization.

No, you are mistaken. I've always had this sig.

Reading time is what was missing.

The error is in the summary, where it says "The Navy plans to fire 5-inch diameter non-explosive projectiles from deck-mounted railguns."
