I wonder how they plan to overcome the problems the last attempts had
I’m kind of skeptical too, but if you’re referring to the Navy’s railgun project, I can believe that maybe they don’t need the kind of ranges and velocities there.

No, sounds comparable; about Mach 6 for each. Maybe a little more for the Navy project. The Navy project was apparently “EMRG”:
In EMRG, “magnetic fields created by high electrical currents accelerate a
sliding metal conductor, or armature, between two rails to launch projectiles at [speeds of] 4,500
mph to 5,600 mph,”42 or roughly Mach 5.9 to Mach 7.4 at sea level.
