High-Energy Laser Effector Tested On German Warship (upi.com)
Rheinmetall and the German armed forces have completed a recent test of their high-energy laser effector on a German warship. During the test, a 10-kilowatt high-energy laser, or HEL, was mounted on a MLG 27 light naval gun. The HEL was then used to track potential targets, which included unmanned aerial vehicles and stationary land targets. The test marked the first demonstration of the HEL on a naval platform, which Rheinmetall says revealed insights for developing future maritime HEL effectors.

That is to say, it was on a German warship when it was tested. They didn't melt a German warship with a laser, which would have been way cooler.
I don't know if they even melted anything. All it says is that they tracked stuff with it.
And what's the difference between a laser and a laser effector?
