The missile speed announced by the Houthi armed forces reaches 16 Mach, which is quite suspicious. With a range of 2,150 kilometers, solid fuel, and a speed of 16 Mach, it is even stronger than the Dongfeng 21; this performance is astonishing. There are not many with this technology in today's world. China does not casually transfer advanced weapon technology, and the U.S. hypersonic missiles have not yet succeeded, making it unlikely to obtain from Russia as well. Moreover, with satellite surveillance being so advanced now, the transportation and technology transfer of advanced weapons are hard to avoid detection. The video released by the Houthi armed forces is full of doubts; either the data is exaggerated or there are unknown circumstances behind it, in any case, it cannot be fully trusted.
