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.
[3][4] Both of them are designed for launch using a solid rocket booster, with the projectile separating from it at a high altitude and then gliding at hypersonic speeds until impact.
[2][5] In Block 2, glide performance will be further improved by introducing waverider technology.
[5] Radio-frequency imaging and infrared homing would also be used for guidance when engaging moving targets.
[5] Special armour-piercing ammunitions, capable of penetrating the deck of aircraft carriers, are used to attack ships, and high-density explosively formed projectiles (EFPs), capable of area suppression, are used to attack ground targets.
