the Navy has the goal of using the railgun to fire 200 nautical miles with Mach 7 velocity using 64 megajoules with full deployment to ships in about 2020-2025.

The Office of Naval Research said railgun achieved a world-record 33-megajoule shot. That energy measurement means the Navy could fire projectiles at least 110 miles.
