What does the term "hypervelocity" refer to in ballistics?

The term "hypervelocity" specifically refers to velocities that exceed 1,500 meters per second. This classification is significant in ballistics as hypervelocity projectiles demonstrate unique physical characteristics and phenomena compared to those traveling at lower velocities. At these speeds, the behavior of the projectile changes notably due to the effects of aerodynamics, shockwaves, and potentially the impact dynamics with targets.

Understanding this term is critical in advanced ballistics because hypervelocity can lead to different results in terms of penetration, damage, and the physics of impact. This is particularly relevant in military applications and space exploration, where projectiles may achieve these high speeds. Recognizing the thresholds of hypervelocity compared to lower velocities helps in correctly assessing the behavior and impact of different types of ammunition or projectiles when discussing their applications in various scenarios.
