Youtube of the day: The much-talked about South China Sea combat drill

"Most noteworthy is the YJ-12 Supersonic Anti-Ship Missile being launched by a H-6 bomber. The YJ-12 has a reported range of 400KM and a top speed of Mach 4."

"The highlight of the 'YJ-12' is not its range but speed. It can reach 'Double Three' or 'Double Four', namely a range of 300 kilometers at Mach 3 (1.02 kilometers per second) or a range of 400 kilometers at Mach 4 (1.36 kilometers per second)."

Impressive design indeed. Can it be used against fast moving vessels?

China would probably use it against a capital ship. A large naval vessel usually travels at a top speed of 30 knots or 35 miles per hour. A cruise missile with a modern computer processor shouldn't have any trouble targeting a capital ship (e.g. destroyer or carrier).

Also, you already know China's FN-6 MANPADS have been shooting down helicopters in Syria. This demonstrates the effectiveness of China's missile sensor technology. Since a helicopter flies much faster than a moving ship, Chinese missile sensors should be able to easily target and lock onto a moving ship.

Finally, Chinese CH-4 UAVs fire missiles that can strike fast-moving vehicles. Since a capital ship is 1,000 feet long and a truck is 20 feet in length, it should be a simple matter for a Chinese missile sensor to hit a very large moving naval ship.

Syrian Rebels FN-6 missile launch and down helicopter. FN-6 (FN = FeiNu, 飞弩, meaning Flying Crossbow), is a third generation passive infrared (IR) man portable air defence system (MANPADS). It was developed by China, and is their most advanced surface-to-air missile offered in the international market[citation needed]. Specially designed to engage low flying targets, it has a range of 6 km and a maximum altitude of 3.5 km. The FN-6 is in service with the People\'s Liberation Army (PLA), and has also been exported to Malaysia, Cambodia, Sudan and Peru. Based on FN-6, China has developed a number of other MANPADS, such as HN and FY series, as well as other vehicle based short range air defense systems such as FN and FB series."

"The CH-4's electro-optical sensor turret has multi-spectral capability (visible light and infrared), software for tracking and identifying moving targets, and inertial guidance to improve accuracy and location-finding in adverse conditions."
