A recent advancement in gallium oxide semiconductor technology by a Chinese research team could give China a significant advantage in radar technology over the United States. Published in February, the research demonstrates that kappa-gallium oxide can store data and function as a high-power transmitter, potentially allowing China to leap two generations ahead in military electronics. Currently, Chinese fighter jets utilize gallium nitride radar systems, surpassing the capabilities of older US systems like those in the F-22, which uses gallium arsenide. While the US plans to upgrade the F-35 with gallium nitride radars, delays have occurred, partly due to Chinese export controls on gallium. This new gallium oxide development could further widen the technological gap, as it offers enhanced capabilities compared to gallium nitride.
