A hypersonic weapon is a weapon capable of travelling at hypersonic speed, defined as between 5 and 25 times the speed of sound or about 1 to 5 miles per second (1.6 to 8.0 km/s).[1]
Below such speeds, weapons would be characterized as subsonic or supersonic, while above such speeds, the molecules of the atmosphere disassociate into a plasma which makes control and communication difficult. Directed-energy weapons such as lasers may operate at higher speeds but are considered a different class of weaponry.
Hypersonic air-to-air missile: an AAM which use air-breathing engines such as scramjet to intercept air targets (such as Vympel R-37)
History
This section needs expansion. You can help by adding to it. (March 2023)
The Silbervogel was the first design for a hypersonic weapon and was developed by German scientists in the 1930s.[3]
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.[4] A volley of Russian hypersonic missiles were launched at Kyiv in January 2023.[5]
YJ-21. According to a South China Morning Post report, in December 2023, Chinese hypersonic anti-ship missiles went undetected in a computer-simulated attack against the US warships in a Chinese research lab.[6][7] The missile range was reported to be similar to that of YJ-21.[7]
France
VERAS hypersonic glide vehicle (first French program on hypersonics; launched in 1965 and cancelled in 1971)
ASN4G hypersonic air-launched cruise missile (under development; technological work on the missile began in the early 1990s and scheduled to succeed the ASMP in the pre-strategic deterrence role in 2035)
LEA hypersonic cruise demonstrator (project launched in 2003 to validate technologies for the ASN4G program)
Prométhée scramjet missile program (little is known about the program beyond the fact that a test, codenamed ASTRÉE, of a mixed ramjet capable of successive subsonic and supersonic combustion was carried out in the United States in either 2021 or 2022)[8][9]
VMaX (Véhicule Manœuvrant Expérimental) hypersonic glide vehicle (first flight test took place on June 26, 2023, from the DGA's site in Biscarrosse and was successful)[10][11][12][13][14]
VMaX-2 hypersonic glide vehicle (first flight test scheduled for 2024 or 2025)

European Union
HYDIS² (HYpersonic Defence Interceptor Study) between France, Italy, Germany and the Netherlands: Announced on June 20, 2023, it is a project led by MBDA. It was selected in March 2023 and partially funded by the European Defense Fund (EDF). Its aim is to propose an architecture and technology maturation concept study for an endo-atmospheric interceptor to counter new, highly sophisticated emerging threats. HYDIS² is centered around the MBDA's Aquila hypersonic missile interceptor concept and will involve a consortium of 19 partners and over 30 subcontractors from 14 European countries.[20] France, Germany, Italy and the Netherlands have already confirmed their support and commitment, by signing a letter of intent and agreeing to initial joint requirements.[21] The ultimate goal of the project is to develop a countermeasure that could be integrated into the French-led EU TWISTER (Timely Warning and Interception with Space-based TheatER surveillance) capability program. TWISTER, launched in 2019 with MBDA France acting as lead contractor as well, is intended to be an air defense system capable of early warning, tracking and intercepting high-performance air threats, including defense against ballistic missiles (BMD) and hypersonic vehicles.[22][23] The program involves France, Italy, Spain, the Netherlands, Finland and Germany.[24]
EU HYDEF (European Hypersonic Defence Interceptor): Competing against HYDIS², this project also covers the concept phase to develop an endo-atmospheric interceptor and is related to TWISTER. Selected in July 2022, it is also partially funded by the EDF. It is coordinated by Spain's SENER Aeroespacial Sociedad Anonima, while Germany's Diehl Defence is serving as the overall technical lead. They are heading a consortium of partners and subcontractors from various EU countries.[23]
Israel
On June 14, 2023 Rafael Advanced Defense Systems announced the SkySonic hypersonic missile interceptor missile, it is assumed that the missile could take out threats between 20 and 70 km altitude, the missile will be officially displayed in the Paris Air show 2023.
Next-gen interceptor and Enhanced Hypersonic Missile Defense system are under development by U.S. Missile Defense Agency. In June 2022, Raytheon and Northrop Grumman were selected by the MDA to develop the Glide Phase Interceptor (GPI) after Lockheed Martin was disqualified from the competition.[27] In September 2022, it was announced that the program had entered the preliminary design phase.[28]United States Space Force has a tracking satellites program.[29]
