It is something of
an open secret that China has been developing hypersonic boost-glide vehicles
for some time now.
The appearance of 16 mockups of the DF-17, the first time this weapon has been shown in any format, at the parade only drove home Chinese ambitions in this regard.
The DF-17, which has reportedly been in testing
since at least 2017, uses the rocket booster from the already operational
DF-16B short-range ballistic missile. On top, instead of a traditional warhead, however, is an unpowered hypersonic boost-glide vehicle, which reports have previously referred to as the DF-ZF or WU-14.
The shape of the vehicle on the mockup DF-17 missiles in the parade was, not surprisingly, similar, if not identical to a wind tunnel model, footage of which appeared
on Chinese state television in 2017. It also looks very much like vehicles involved in an apparent
high-altitude drop test in northwestern China in 2018. Chinese testing of earlier hypersonic boost-glide vehicles dates back to at least 2014.

The DF-17s shown at the parade are indeed mockups. Not actual weapon systems...
Those DF-17s are mockups. Those are clearly not mature weapon systems.
