Hypersonic weapon

There are two main categories of hypersonic weapon: • Boost-glide hypersonic weapons, which glide and maneuver at hypersonic speeds following boosting by rocket propulsion. Typical examples are ballistic missiles fitted with hypersonic glide vehicle warheads. • Airbreathing hypersonic weapons, typically hypersonic cruise missiles which maintain hypersonic speed by engines such as scramjets. but are not typically classified as hypersonic weapons due to lacking the use of aerodynamic lift to allow their reentry vehicles to maneuver under guided flight within the atmosphere. Maneuverable reentry vehicles, such as employed on the Pershing II, Fattah-1 and DF-21D, are generally excluded from this definition as they maneuver aerodynamically only for short periods of time during the terminal phase, and lack the significant cross-range maneuverability expected from hypersonic weapons. ==History==

The Silbervogel was the first design for a hypersonic weapon and was developed by German scientists in the 1930s, but was never constructed. The ASALM (Advanced Strategic Air-Launched Missile) was a medium-range strategic missile program developed in the late 1970s for the United States Air Force; the missile's development reached the stage of propulsion-system testing, test-flown to Mach 5.5 before being cancelled in 1980. In the 2022 Russian invasion of Ukraine, Russia was seen to have fielded operational weapons and used them for combat. The Kremlin presents new hypersonic weapons as supposedly capable of overcoming "any" foreign missile defense systems, with the "pre-nuclear deterrence" concept contained in its 2014 iteration of the official Russian Military Doctrine. A volley of Russian hypersonic missiles were launched at Kyiv in January 2023. ==Hypersonic weapon examples==
