Looks like the technology is reaching sufficient maturity to be a viable defence weapon against UAV's.
Rheinmetall HEL Technology
Following the recent test ...
Witnessed by leading experts, the demonstration delivered compelling evidence for the 50kW HEL weapon technology demonstrator’s high stability: a massive, 15mm-thick steel girder was cut through at a distance of 1,000 metres. The successful shooting down of several nose-diving target drones at a range of two kilometres formed the second major highlight. Though they were flying at over 50 metres a second, the Skyguard radar had no trouble detecting the incoming unmanned aerial vehicles at a distance of three kilometres. Then the 30kW weapon station used the Skyguard data to carry out rough tracking mechanically. The optical tracking system in the Beam Forming Units (BFU’s) in the individual leaser weapon modules performed fine tracking of the UAVs. After reaching the programmed fire sector the laser weapon modules engaged the UAV’s immediately and destroyed the incoming UAVs within a few seconds.
Just a few more steps I guess until the technology becomes truly viable against low flying strike aircraft ...
