US Naval Research Laboratory (NRL) scientists have successfully demonstrated a dual-use laser system capable of wirelessly transmitting power over long distances and rapidly transitioning to perform aerial defence.
A recent demonstration showed how a fielded laser system could provide remote power delivery while maintaining its original mission as a directed-energy defence capability and take down a drone. The demonstration was conducted in partnership with Boeing and the DEVCOM Ground Vehicle Systems Center and with collaboration across Navy, Marine Corps and Army stakeholders. The laser system used in the demonstration has already been fielded by the US Marine Corps for directed energy applications.
Using a trailer-mounted laser positioned across an airfield, researchers transmitted power from a standard military vehicle to specialised receivers at a remote location. The same laser system then transitioned without delay to address the simulated aerial threat.
The team tested the system through severe weather, including snowfall approaching whiteout conditions. NRL Research Physicist Justin Lorentzen said that testing in wind, snow and real atmospheric interference provided the data needed to improve the system and move it towards a true operational capability.
Researchers say the next phase includes additional demonstrations to gather direct user feedback to tailor the system for operational needs.
