Any news about HN-2000 cruise missile mentioned in this article from 2018 (page 5)? Or is HN-2000 missile the CJ-100 shown in last years parade?
There seem to be confusion on what is what. There is a Kh-55 based cruise missile which surely expanded into multiple programs for LACM and that branched off into various air/sub/ship/land launched LACM and AShM. These are the CJ-10/A, DH-10/A, HN-2 and HN-3 series. These are the early 2000s development and I recall first "type/s" of these LACM were in service before 2010. There were lots of discussions on a Tomahawk equivalent back in the mid and late 2000s when this became more well known and less secretive after that when they've reached widespread service.
For the CJ-100 or DF-100, that's a scramjet powered, rocket boosted, high supersonic or hypersonic "cruise missile" that is the rapid response, "regional strike" weapon. Perhaps designated by Easton and some analysts as HN-2000?
The Qian Xueshen prompt global strike weapon would be something based on Qian Xueshen trajectory so DF-ZF or some other HGV weapon that rides its shockwaves within the atmosphere after re-entering as opposed to Sanger trajectory for example where the vehicle uses the atmosphere to "bounce" a few times before re-entering and basically being ballistic.
Since we've seen some VERY grainy outlines of the DF-100/ CJ-100's body (and some "Starry Sky" test vehicles which probably is similar in performance and general aerodynamic design), it's almost certainly not a waverider in that sense. It's basically a high supersonic/low hypersonic missile which is rocket boosted to higher atmosphere and then the scramjet takes over, frame materials and aerodynamics resists the heat and stresses of the missile in flight and makes use of its altitude and maintained cruising speeds.
So the CJ-10/HN-2/HN-3/DH-10 are different families of subsonic (possibly supersonic homing phase) cruise missiles that developed out of Kh-55. Basically Tomahawk equivalents that were branched off according to launching platform, task of missile, and been upgraded and modernised over the years. The CJ-100/DF-100 is an entirely different type of high supersonic/low hypersonic (since it's probably only scramjet powered and rocket boosted) "cruise missiles" and the Qian Xueshen trajectory missiles are HGVs whether rocket boosted and glide or rocket and/or air launched sodramjet/exotic propulsion/combined cycled, and is another family of weapons.
Based on what is known and shown, I would guess the rough development start to service for the three are, CJ-10 family = late 1990s and first service late 2000s. DF-100 = developed starting late 2000s early 2010 and first service before 2019. HGVs developed 2000s and service before 2019.
Development and programs probably go way back but required supercomputers, wind tunnels and hypersonic wind tunnels at the very least to be capable enough. Then the obligatory 10 or so years to develop something in earnest i.e. not just having a program for something. We know hypersonic weapons research went as far back as Qian Xueshen so 1960s easily but we can't exactly say these specific weapons platform developments started back then.
