Could railguns still support troops ashore?

Could a long-range railgun still provide effective naval gunfire support for troops ashore?

Yes in principle; maximum range does not prevent closer shots, and kinetic or explosive projectiles could support land forces if rail wear and reliability are solved.

A viewer asks whether an extreme-range railgun would still be useful for supporting troops ashore. A weapon's maximum range is not its minimum range, so the ship could fire at closer objectives. A high-velocity kinetic projectile could create substantial effects from impact energy, while other rounds might carry an explosive payload. The major qualification is repeated-fire reliability because the copper rails and associated materials must survive sustained use. Naval gunfire support is therefore a plausible mission, but it depends on solving the weapon's engineering and ammunition problems.
