Hypersonic glide vehicle
A hypersonic glide vehicle (HGV) is a type of warhead for ballistic missiles that can maneuver and glide at hypersonic speed. It is used in conjunction with ballistic missiles to significantly change their trajectories after launch. Conventional ballistic missiles follow a predictable ballistic trajectory and are vulnerable to interception by the latest anti-ballistic missile (ABM) systems. The in-flight maneuverability of HGVs makes them unpredictable, allowing them to effectively evade air defenses.[1][2][3] As of 2022[update], hypersonic glide vehicles are the subject of an arms race.[4]

Countermeasures
[edit]Boost-glide weapons are generally designed to avoid existing missile defense systems, either by continually maneuvering or by flying at lower altitudes to reduce warning time. This generally makes such weapons easier to intercept using defensive systems intended for lower-altitude "low-tier" targets. Flying at lower speeds than short-range ballistic missile warheads makes them easier to attack.[20] Those that approach with very low terminal attack profiles are even subject to attack by modern hypervelocity guns and railguns.[21]
Hypersonics, like the Avangard HGV, generally use scramjet engines to achieve hypersonic speeds. Scramjet engines function only when the glide vehicle reaches mach 4.5. These engines are disengaged as the HGV enters the terminal phase of its flight. Failure to deactivate the engines would cause a catastrophic build up of heat in the vehicle as the atmosphere becomes denser during reentry, prematurely destroying the vehicle. Therefore, the terminal phase of an HGV's re-entry is similar to that of a multiple independently targetable reentry vehicle. For instance, the Avangard would not hit its target while "zig-zagging" at Mach 27, but rather would impact at a velocity under Mach 4 and on a linear trajectory.[citation needed] The superior evasion capabilities that HGVs employ are largely limited to the upper atmospheric flight span.[22][23][24]

The downside is when the [HGV] warhead nears its target, it has less speed and altitude and is therefore more easily intercepted by low-tier interceptors, including potential rail guns.
