Hyper Velocity Gliding Projectile (HVGP) (島嶼防衛用高速滑空弾, Tōsyobōeiyō-kōsoku-kakkūdan) is a Japanese hypersonic glide vehicle being intended to be used as a hypersonic weapon in defending of remote islands. [1] [2]

[19] It is possible that the Hwasong-12B was renamed from Hwasong-8. [20] Hwasong-16B (tested in April 2024). [21] There have also been reports of other hypersonic glide vehicle being mounted on the other ballistic ...

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). The main article for this category is Hypersonic weapon .

The subsonic speed range is that range of speeds within which, all of the airflow over an aircraft is less than Mach 1. The critical Mach number (Mcrit) is lowest free stream Mach number at which airflow over any part of the aircraft first reaches Mach 1. So the subsonic speed range includes all speeds that are less than Mcrit.
In February 1949, at White Sands, the rocket reached a speed of 8,290 km/h (5,150 mph), or about Mach 6.7. [2] The vehicle, however, burned on atmospheric re-entry, and only charred remnants were found. In April 1961, Russian Major Yuri Gagarin became the first human to travel at hypersonic speed, during the world's first piloted orbital flight.
Work on the HTV-2 would continue to summer 2014 to provide more study on hypersonic flight. The HTV-2 was the last active part of the Falcon program. DARPA has now changed its focus for the program from global/strategic strike to high-speed tactical deployment to penetrate air defenses and hit targets quickly from a safe distance. [31]
