No, this is in fact not categorically new. MaRV and related demonstrated 60 G pull up to horizontal glide maneuvers.
The technology of a HGV and a maneuverable re-entry vehicle are essentially the same. The main reason for talking about "hypersonics" as a separate category today is to emphasize flight profiles that would not be interpreted as nuclear strikes.
- littlestymaar 4y agoAs I understand it, it's not about “not being interpreted as nuclear strike” — since almost every Russian missile (including anti-ship missiles like Kh22 and the likes) could potentially carry a nuclear warhead, they explicitly don't care about the ambiguity, while the Western doctrine is diametrically opposite, explicitly aiming for as little ambiguity as possible to keep the escalation risk low. And your interpretation basically goes against both doctrines. — But more about keeping a low trajectory so that the missile stays below the early-warning radar horizon for most of its flight, striking without warning, where a ballistic missile gets within the LOS of radars quite early due to its trajectory.
- superkuh 4y agoYeah, ICBMs have slightly glidy, menuevering entry vehicles. But these don't fly. It's more like falling with style. And they certainly don't have shapes that aren't simple conicals. Otherwise the heat from compression and where the shockwaves impinge on the complex structure completely overcomes materials tech and any possible heat soak or re-radiation.
