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.

Yeah, I don't know, seems a corner case at best.
I suppose if you can steer it in flight, you could fire it over a shallow sub that your sonar has detected, and then dive them into the water at the steepest angle you could muster.
I doubt the sub would be at much risk if it was a couple hundred feet down.
No, you are mistaken. I've always had this sig.
