![]() ![]() This approach to missile defense has proven very effective against ballistic missiles, which do travel at hypersonic speeds, but along a fairly predictable ballistic flight path. It’s the same basic principle as a quarterback leading a receiver: you don’t throw the ball to where the receiver is, but rather, to where the receiver will be by the time the ball gets there. With its course determined, air defense systems, like America’s MIM-104 Patriot, then launch a missile of their own, known as an interceptor, to fly toward a point further along the inbound weapon’s flight path to intercept it. ![]() ![]() While the air defense enterprise is an incredibly complex one, the job itself is somewhat simple: Air defense systems identify and track inbound weapons using sensors, like radar, and then use computers to calculate the remainder of the weapon’s inbound flight path. Modern hypersonic missiles, which combine flying at speeds in excess of Mach 5 with the ability to change course unpredictably, pose a unique challenge for even today’s most advanced integrated air defense systems. Lasers may be the cure for whatever ails you in science fiction, but if America is looking for a real solution to the myriad problems posed by modern hypersonic weapons, lasers – or directed energy weapons – won’t be able to provide the magic bullet that we’re looking for. ![]()
