Why is this thread still being cluttered by attempts to conflate HEL and DIRCM?
DIRCM l@sers are about the size of a hardback book, because they have to fit along with a tracking camera into the small turrets you see attached to a C-17.
They have a power output at best in the low tens of watts.
HEL
starts at 10 kW, which I think everyone understands is three orders of magnitude difference. Some claim that you can knock down a plastic mini-drone at a few kilometers with that much power. So far, airborne systems designed for counter-surface or counter-missile roles are considered generally viable at 100-150 kW and upward, or 10000 TIMES the output of a DIRCM.
Babbling about demonstrator DIRCMs is pure timewasting.
