Army soldiers not impressed with 50-kilowatt lasers

Thursday, May 16th, 2024

The US Army sent four Stryker-mounted 50-kilowatt laser prototypes to the Middle East to test against aerial threats:

“What we’re finding is where the challenges are with directed energy at different power levels,” Bush told members of the Senate Appropriations airland subcommittee on Wednesday. “That [50-kilowatt] power level is proving challenging to incorporate into a vehicle that has to move around constantly — the heat dissipation, the amount of electronics, kind of the wear and tear of a vehicle in a tactical environment versus a fixed site.”

Dubbed the Directed Energy Maneuver Short-Range Air Defense (DE M-SHORAD), the service tasked Kord Technologies with integrating a 50-kilowatt class RTX laser onto a Stryker to down class one to three aerial drones and incoming rockets, artillery and mortars. In total, four prototypes were produced, and Breaking Defense first reported that all four were sent to the US Central Command (CENTCOM) region in February.

Army Vice Chief of Staff Gen. James Mingus said at the time that the goal was to experiment in a live environment complete with weather challenges and dust storms that can alter light particles and degrade beam quality.

“You may have a 50-kilowatt laser, [but] at 10 kilometers can you put at least four kilowatts in a centimeter square because … that’s what you need to burn through a quarter inch steel plate?” the three-star general asked. “But that’s really hard to get … from a big beam to get the small portion of it on the exact spot to be able to burn at that high intensity and any kind of dust particle or that starts to disrupt that.”

    I did a few searches trying to find good news about long-range electrolasers, but I only found short-range devices suitable for clearing IEDs.
