China New Hypersonic Vehicle: WU-14


China New Hypersonic Vehicle: WU-14

Author: Dasein

                In 2014, some of the US media said China successfully tested a Mach 10 hypersonic vehicle, named WU-14 by the US government. The media said WU-14 worked in 100km above the sea level. 100km is an abnormal altitude for hypersonic vehicle because the US hypersonic transport vehicle (HTV) worked in a much lower altitude, let say 70000ft for X-51 [1]. It seems that WU-14 was flying as ballistic missiles (Altitude: 150km up [3]). In the sky 100km above the sea, there is no oxygen [4], therefore WU-41 is a rocket powered vehicle. For 70000ft sky level, X-51 can enjoy 5% oxygen in the sky, therefore X-51 is powered by JP-7 (the US military fuel) or ethylene.

Regards to the altitude, WU-14 is not very much alike with X-51, HSSW [5] or DARPA [6] programme. I would say WU-14 is some kind of ballistic technology. WU-14 can be very sophisticated, but it may not as complicated as the cutting edge HTV technology.

                It would be important for us to understand more about what WU-14 can do. Regard to the US HTVs, they are usually experimental planes, reconnaissance planes or missile vehicles. For example, Prompt Global Strike (PGS) [7] is a conventional missile system operating 50000ft above the sea level. It seems that China has no demand in using HTV as transportation vehicles. Also, the very high altitude of WU-14 makes it unlikely to be reconnaissance planes because WU-14 may not provide images better than satellite images. Eventually, it is more likely for WU-14 to be developed as weapon vehicle.

                If WU-14 is designed to carry conventional weapons, we can implied 2 facts: WU-14 is not designed to fight against nuclear states, such as the US and Russia, because a real nuclear strike back will be fired before WU-14 lands on enemy soil. Also, WU-14 can provide a strategical support. Taking the potential war zones into account, WU-14 should have range about 1000km in order to cover South Korea, some part of Japan and Taiwan.

                Some people would think WU-14 is just a short range ballistic missile. However, I believe that there are some differences between WU-14 system and ballistic missile.

                With reference to Kanwa Defence Review (KDR) (No.111), KDR did not noticed any Naval nor Second Artillery Corps officer in a military drill against Taiwan. In other words, there could be no ballistic missiles for supporting military action strategically. WU-14 can be the one option that the Air Force in hand for rapid air support.

                To sum up, WU-14 is a vehicle filled with many unknowns. However, it is almost certain that WU-14 is designed to fight against Taiwan and Japan. WU-14 could become the best advertisement for F-35B (STOVL plane), THAAD and NMD system in the Far East.
