Next Big Future:
Mach 3 hypervelocity projectiles can be fired from regular 5 inch and 155 mm guns on land and sea. They can revolutionize defense against ballistic missiles because small, smart projectiles can be inexpensive. It takes 300 seconds to pick up such a launched missile’s signature, the missile must be tracked and a vector calculated for defensive projectiles. A single 25-pound projectile can dispense more than 500 three-gram tungsten impactors and be fired at hypervelocity by electromagnetic energy. Their impact force—their mass times the square of their velocity—can destroy expensive missiles and multiple warhead.
April 11, 2016, press report stated: The Pentagon wants to take a weapon originally designed for offense, flip its punch for defense and demonstrate by 2018 the potential for the Army and Navy to conduct missile defense of bases, ports and ships using traditional field guns to fire a new hypervelocity round guided by a mobile, ground variant of an Air Force fighter aircraft radar.
