As for the Japanese projects, the development of weapons will be carried out in the framework of the project Hyper Velocity Projectile Gliding (HVGP). At the moment it is known that the first samples of weapons should have a speed around 5.5-6 swings throughout the greater part of the time required for approaching the target. In addition to cruise missiles, the project will be taken on Board aircraft and missile defense system against hypersonic missiles of a potential enemy, and has all the necessary infrastructure.
