In the sky, the bulk of the aerial combat group roared through the dust and exhaust smoke produced by moving vehicles on the ground. The group was comprised of early-warning and control aircraft, bombers, transport planes, refueling tankers, aircraft carrier-borne and land-base fighter jets and a mechanized parachute unit.

The J-20 supersonic stealth jet, the world's third kind of fifth-generation fighter jet, KJ-500 early-warning and control plane and Y-20 strategic transport jet were among the aircraft in the sky. The next two groups were logistics support and counter-terrorism forces.

However, it was the PLA Rocket Force, the last group to appear, that were perhaps the most eye-catching. Wheeled launch vehicles carried five types of ballistic missiles including DF-16G, DF-21D and DF-26. According to the Rocket Force, DF-16G carries conventional warheads and has high accuracy, strong destructive power and requires only a short time for preparations.

The DF-21D land-based, anti-ship ballistic missile features a large coverage and good penetration and target-tracking capabilities. It is a milestone in the PLA's efforts to implant strategic capacity into its conventional ballistic missiles.

The DF-26, a new strategic deterrence weapon, is capable of conducting off-road launches of conventional and nuclear warheads in tough terrains. It can carry out rapid nuclear counterattack and medium- to long-range precision strikes using conventional warheads, according to the Rocket Force.
