DF-100 Hypersonic Cruise Missile at
National Day Military Parade 2019. With a range of 2000-3000 kms that is
capable of hitting land targets or large warships.
The People's Liberation Army Rocket Force, or PLARF,
posted
the full video on social media on Sept. 25, 2019. Sometime afterward,
the original one-minute long montage was replaced with one that omitted
the launch of the unknown weapon and replaced it with unrelated footage
of known missiles, according to the
SCMP.
There is no obvious indication about what this new missile is or what
its mission may be. The video shows that it is vertically launched from a
10-wheel transporter-erector-launcher (TEL) that appears to be able to
carry two of the weapons in a ready-to-fire configuration. Photos of
preparations for the 70th-anniversary parade in Beijing on Oct. 1, 2019,
have shown a similar, previously unseen TEL with its entire rear
section tarped off.

The weapon itself appears to have at least two distinct parts, a main
body with a very large rocket booster attached to the end. The booster
would fall away at some point in the early stage of flight.
The main weapon has large strakes or fins and what appear to be a number
of relatively long and thin fairings at the tail end, which some have
suggested could be
ramjet
intakes. An air-breathing ramjet propulsion system would fit with the
large booster motor, since the weapon would then need to get up to an
appropriate speed and altitude before its engines could function
properly. A number of existing Chinese supersonic anti-ship missiles,
such as
the YJ-12 series or
the newer HD-1, use a similar general configuration.

The PLARF already operates the ground-based subsonic
CJ-10
land-attack cruise missile, which has a range of approximately 930
miles. This has led some to believe that this new weapon is a
supersonic, or possibly hypersonic, land-attack cruise missile intended
to replace that existing weapon.
Hypersonic speed is defined as
greater than Mach 5.
The wide nose and missile body, together with the strakes/fins, would
seem to make it unlikely that this is indeed a hypersonic weapon.
Others have posited that it could be a
new quasi-ballistic missile.
However, the strakes/fins and possible ramjet propulsion would be at
odds with what one would expect to see in a weapon that is supposed to
fly in a ballistic flight path.
Regardless of the exact nature of its configuration, the weapon could
also potentially be intended for other roles instead of or in addition
to striking land targets, including engaging hostile ships at extended
ranges. The PLARF has already developed significant
anti-ship ballistic missile capabilities, most notably with
the DF-21D medium-range ballistic missile and
the DF-26 intermediate-range ballistic missile, the latter of which is seen in the video below.
