Modern ship radars can track a thousand targets at once

For over seventy years, Japan’s pacifist constitution strictly prohibited the export of lethal military hardware. That era ended with the development of the Mogami-class frigate, a ship designed to track one thousand targets simultaneously across a four-hundred-kilometer radius. Unlike older systems that rely on spinning dishes, these vessels use stationary panels of gallium-nitride amplifiers to steer invisible beams of energy at the speed of light.
