Just missed May the 4th, but this just happened last week.
“Amphibious transport dock ship USS Portland (LPD 27) successfully disabled an unmanned aerial vehicle (UAV) with a Solid State Laser – Technology Maturation Laser Weapon System Demonstrator (LWSD) MK 2 MOD 0 on May 16. ”
As noted by U.S. Pacific Fleet Public Affairs:
LWSD is a high-energy laser weapon system demonstrator developed by the Office of Naval Research and installed on Portland for an at-sea demonstration. LWSD’s operational employment on a Pacific Fleet ship is the first system-level implementation of a high-energy class solid-state laser. The laser system was developed by Northrup Grumman, with full System and Ship Integration and Testing led by NSWC Dahlgren and Port Hueneme.
“By conducting advanced at sea tests against UAVs and small crafts, we will gain valuable information on the capabilities of the Solid State Laser Weapons System Demonstrator against potential threats,” said Capt. Karrey Sanders, commanding officer of Portland.
