The recent deployment of China's first four indigenous KJ-2000 AWACS aircraft marks an important milestone in the PLA Air Force’s long march from being a ‘numbers intensive’ low technology force, to a much more modern high technology one. More fundamentally, though, the AWACS (Airborne Warning and Control System) extends China's deep and broad network of air defence Command Control Communications Intelligence Surveillance Reconnaissance (C3ISR) systems into a key airborne area. In doing so, China is now acquiring the radar and passive early warning and air defence command, control and communications it needs to counter foreign fighters and cruise missiles.
