unless its accelerating rocket sacrifices a lot of potential lifting capacity to get it there - as Topol does
SS27 doesn't rely on lift and certainly isn't doing M10.
The Chinese hypersonic prototype is a high apogee, late dive, VERY fast re-entry vehicle. It doesn't rely on stealth or late detection, it relies on being bl00dy difficult to target as a consequence of its flight profile and sheer speed. Even with the possibility of DEW and/or electronic attack (which are, in my opinion, the way to go against this type of threat) it is (potentially) a very serious threat.
