Вот НАТО-вская статья не ранее 2016 года.
Introduction Hypersonic technologies offer potential solutions and applications that could have a strong impact on doctrine and conduct of future military operations. Different applications are conceivable for hypersonic flight vehicles in order to enable new or advanced military capabilities...

По планирующим блокам у США кратное превосходство по количеству программ. Но
Technically, the boost-glide vehicle is likely to be the first operational system, as the number of global successful tests of prototype systems outpaces any other hypersonic technology by far. An operational system is attainable by 2022–2025. Many research projects are aiming at this goal.
По крылатым ракетам тоже США ведут больше программ. Но
While a hypersonic cruise missile will have many positive attributes, several critical technologies are still in development and are uncertain. Widely unresolved issues relate to structural integrity, propulsion efficiency and endurance, as well as precision of flight control and navigation. The requirement for air carriage to the launch position restricts size and mass of the vehicle with impact on military payload and boost rocket mass. The result is a very complex and expensive vehicle.
Research and concept development in this direction are carried out in the US, e.g. X-51, the High Speed Strike Weapon (HSSW), and the Hypersonic Air-breathing Weapon Concept (HAWC). Russia is reported to field a ship-based hypersonic missile (Zircon21; Mach 5–6, range ~250 km) within years and India is working with Russia on the Brahmos II hypersonic missile concept. Reporting indicates that China is also conducting research and development in SCRJ design with the aim to build a hypersonic cruise missile. Figure 10 shows pictures of some hypersonic cruise missile concepts.
Operational readiness of long-range, air-launched hypersonic cruise missiles is very unlikely within the next decade, because of the higher complexity of a powered vehicle in comparison to a glider, but should be attainable within 20 years.
А уж "земля - земля" - это выше пределов планирования НАТО.
И нас хотят убедить, что в России, где режут бюджет на образование и здравоохранение, в 2019 году поставили на боевое дежурство ракету с гипеpзвуковым планируюшим блоком, а в 2020 имеют готовую крылатую гиперзвуковую ракету "земля - земля".
Чудес не бывает.
