China-Japan mid-air faceoff: Beijing explains why JF-15 jet locked radar on F-15 | 'Halt harassment' Tensions between China and Japan have flared sharply after Beijing accused Japanese fighter jets of intruding into its military training zones and conducting close-in reconnaissance. China’s Foreign Ministry spokesperson Guo Jiakun expressed “strong dissatisfaction,” rejecting Japan’s claim that Chinese jets targeted Japanese aircraft with radar near the Okinawa Islands.

In October 2025, Chinese researchers announced the mass production of a four-channel, single-photon detector known as the "photon catcher," a device that could theoretically serve as a foundational component for future quantum radar networks. Developed by the Quantum Information Engineering Technology Research Centre in Anhui province, this breakthrough aims to detect stealth aircraft like the F-22 Raptor and F-35 Lightning II by isolating the faintest traces of energy reflections.
