So, while China’s navy moves from offshore defence to regional capability, its air force is creating an integrated aerospace system for offensive and defensive operations beyond its borders. All this means a virtual assembly line of new generations of aircraft carriers, destroyers, submarines, fighter aircraft, ballistic and cruise missiles and associated systems. In all this, space is a key element for C4ISR—command, control, communications, computers, intelligence, surveillance and reconnaissance. We are talking here not of individual satellites, but constellations. So by 2020, the existing 30 Beidou navigation satellites will be replaced by 35 advanced versions. Already 40 Yaogan satellites move in a triplet formation providing imagery and electronic intelligence. By 2020, China will be able to obtain 30-minute updates from any part of the globe from 60 satellites including the Gaofen and Jilin series. The People’s Liberation Army (PLA) is also working on counter-space systems aimed at knocking out adversary satellites.
