Japan and the United States plan to conduct joint research into the use of high-power microwaves in defense equipment. The Acquisition, Technology and Logistic Agency and other relevant agencies in both countries are expected to soon reach an agreement, with both seeking to acquire the capability of neutralizing drones that enter their territories.
A microwave is a type of electromagnetic wave, which is commonly used in microwave ovens. If a drone is irradiated by microwaves, its internal electronic components can malfunction.
Microwaves can cover a wide area at a lower cost than ammunition and missiles, and they are therefore expected to be effective against attacks using large numbers of small drones. Microwaves can also be used on autonomous drones that do not require radio control.
The Defense Ministry expects weapons using microwaves to be a game changer that could transform the balance of military capabilities.
The Acquisition, Technology and Logistic Agency has been researching related technologies and hopes the joint research will lead to the development of equipment. The joint research is expected to continue for about three years.
