At a time when control of Pacific sea lanes is contested, Japan is positioning its hypersonic electromagnetic railgun development as a strategic centerpiece, aiming to deter Chinese naval threats and shift the regional balance of power.

Tokyo’s latest demonstration, shown by state-run ATLA, displays a prototype railgun firing hypersonic rounds at a moving ship. As the projectile surged forward, the deck shuddered slightly under the silent electromagnetic pulse, while nearby crew members steadied themselves, their expressions a mix of awe and anticipation.

For hitting drones and artillery shells? Almost certainly lasers win.

For hitting ships? Railguns, if the problems with the rails getting festroyed after a few shots can be fixed. The Japanese claim 200 shots per barrel. Whether that means just the rails or whole barrel is unclear.
