Some of those planforms resemble those in an earlier academic paper that many believe is related to the H-20 development program.

Some illustrations from a paper that I don't have access to. They show a morphing nose cone design for a hypersonic spaceplane or missile. The nosecone would change shape to improve airframe efficiency and performance (i.e. increase lift, reduce drag, etc.) at different flight regimes.

An academic paper that proposes a novel design for a hypersonic vehicle. The vehicle has two intakes, one for 'low-to-medium' speeds (up to Mach 5), and the other is optimized for high-speed (up to Mach 7). Depending on speed, one intake will shut off and the other is opened. Interestingly, the aircraft will rotate 180° to ensure the active/open intake will always be on the underside of the fuselage.

, which has following sayings.

When HGVs re-enter the atmosphere at hypersonic velocities a plasma sheet will develop which disrupts their communications and sensors. There are two solutions to this. Firstly, HGVs can slow down to supersonic speeds, but this wouldn't make their terminal phase interception any harder than the missiles that current SAMs are designed to intercept. Secondly, HGVs can maintain hypersonic speeds and rely on inertial navigation systems, though this would mean that HGVs can't target maneuvering targets like expensive aircraft carriers, yet these are the exact targets that are valuable enough for HGVs with costs in the tens of millions each, to be worth targeting. These factors have likely contributed to DF-ZF currently being used for a land-attack role only, although an anti-ship variant is in development.

So, DF-17 is not capable to hit moving targets, like aircraft carriers? Then why DF-21D & DF-26B can? :rolleyes:
