Hypersonic weapon
High-speed missiles and projectiles From Wikipedia, the free encyclopedia
A hypersonic weapon is a weapon capable of travelling at hypersonic speed, defined as above Mach 5, or above 5 times the speed of sound.[1]
Below Mach 1, weapons would be characterized as subsonic, and above Mach 1, as supersonic. Typical Low Earth Orbit atmospheric re-entry speed is Mach 25.[2] At such speed, the molecules of the atmosphere disassociate into a plasma which makes control and communication difficult.
There are multiple types of hypersonic weapon:
- Hypersonic glide vehicle (HGV): missile warheads which maneuver and glide through the atmosphere at high speeds after an initial ballistic launch phase[3][1]
- Hypersonic cruise missile: cruise missiles which use air-breathing engines such as scramjets to reach high speeds[3][1]
- Hypersonic aircraft using air-breathing engines such as scramjets to reach high speeds[1]
- Guns which fire cannon-launched guided projectiles. These may be developments of traditional artillery or novel technologies such as railguns.[1]
Other types of weapons, such as traditional ballistic missiles, may achieve hypersonic speeds 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.[4][5] Weapons such as the Pershing II and DF-21D blur these lines, as they maneuver aerodynamically to ensure a hit against a potentially-moving target, but lacks the full maneuverability that many expect 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.[6]
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[7] 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.[8] A volley of Russian hypersonic missiles were launched at Kyiv in January 2023.[9]
