Since the late 1940s, missiles have been developed with the aim of striking the enemy at long range. These missiles, still present in global arsenals today, are called ballistic missiles because they follow a ballistic flight trajectory, meaning the trajectory of a body that, having an initial velocity, is subjected to the force of gravity and the viscous friction of the medium through which it propagates. This type of missile, called ICBM, consists of a solid- or liquid-fueled rocket carrying a warhead (nuclear or conventional). The rocket is launched and carried out of the atmosphere. Once the fuel is exhausted, the warhead re-enters the atmosphere and begins a descent phase that will bring it to the designated target. During this descent phase, the warhead reaches incredibly high speeds, around Mach 25. The entire trajectory is predetermined, and neither the rocket nor the warhead is capable of altering its flight path. The hypersonic missiles we've been hearing about lately aren't revolutionary in terms of speed. But they are in terms of altitude and maneuverability. These new hypersonic missiles are classified into two categories: • HGV – Hypersonic Glide Vehicle • HCM – Hypersonic Cruise Missile HGVs are gliders, and therefore don't have their own propulsion system. They are launched by a rocket (like ballistic missiles), but after reaching hypersonic speeds during the climb phase, they separate from the rocket before exiting the atmosphere and begin a maneuvered glide phase that will carry them to the designated target. It's therefore clear that HGVs are designed to generate lift and have control surfaces that allow them to modify their trajectory during the glide phase. HCMs, on the other hand, are missiles with an autonomous propulsion system capable of taking them to hypersonic speeds, and they also have movable aerodynamic surfaces that allow them to modify their flight path during flight. The propulsion system is, or should be, given that a combination of a rocket engine and a scramjet is still being studied and tested. As I explained in the video on hypersonic flight (   • Analizziamo una scena di Top Gun: Maverick...  , this propulsion system, although successfully tested in recent years, still poses significant technological challenges. The speeds reached by missiles of this type range between Mach 5 and Mach 8. The problem with new hypersonic missiles isn't so much that they are hypersonic, but that they fly at lower altitudes and are maneuverable. In the first case, the problem is that currently used missile defense systems would not be able to detect the missile early enough. The second problem means that, even if it were detected in time, the missile, which would be launched as neutralized, could be avoided precisely thanks to its maneuverability. Another advantage of a missile of this type is its intrinsic stealth capability. At those speeds, the layer of air surrounding the missile ionizes, becoming a very high-temperature plasma. This plasma, due to its properties, absorbs electromagnetic radiation and does not reflect it, thus making the missile invisible to radar. As for the US, the most advanced project of all is the HAWC project, a scramjet-equipped cruise missile successfully tested in March 2022 but kept under wraps to avoid escalation in the ongoing conflict. According to the Americans, all their projects do not involve the use of explosive warheads (nuclear or conventional) but rather aim to exploit the missile's enormous kinetic energy (due to its velocity) to destroy the target. The energy released by an impact with a massless object at hypersonic speed would be so high that explosives could be dispensed with, resulting in a reduction in weight or more sophisticated systems for the same weight. Although the project is at an advanced stage, this weapon is still not expected to be operational before 2023. China has had the DF-17 medium-range solid-fuel ballistic missile, which it mounts the DF-ZF HGV, since 2019. Furthermore Finally, we come to Russia, which apparently has a hypersonic weapons system already in use and others ready to enter operational use. But let's clarify this as well. The missiles that are always mentioned are: • Sarmat • Kinzhal • Zircon • Avangard #hypersonicmissile #avangard #hawc #df17 #ACDrone
