Hypersonic technology refers to vehicles or missiles capable of traveling at speeds greater than Mach 5, five times the speed of sound. These weapons can maneuver unpredictably, making interception difficult for traditional defense systems. Countries like the USA, Russia, and India are investing heavily in hypersonic research for strategic and tactical advantages. Hypersonic technology enhances rapid response capabilities, strengthens deterrence, and challenges existing missile defense systems. Its development requires advanced materials, propulsion systems, and guidance mechanisms, reflecting the intersection of aerospace, materials science, and artificial intelligence in modern defense technology.
