China Uses Verbal Warnings and Electronic Countermeasures Against Aircraft

Chinese air and naval forces had issued verbal warnings as well as using unspecified electronic “countermeasures” to “drive the aircraft away”, the People’s Liberation Army command said. Fu Qianshao, a former air force pilot turned military analyst, said this was a “very serious form of warning” but “of course, not the most serious”. He added: “This can involve transmitting electromagnetic signals to disrupt an adversary’s communications, radar or sensors – either through broad-spectrum barrage jamming or by targeting specific frequencies and wavelengths.”
