Quest for ‘super-duper’ missiles at heart of US rivalry with China, Russia

WASHINGTON (AP) — They fly at speeds of a mile a second or faster and maneuver in ways that make them extra difficult to detect and destroy in flight.
US President Donald Trump calls them “super-duper” missiles though they’re better known as hypersonic weapons. And they are at the heart of Trump administration worries about China and Russia.
For decades the United States has searched for ways to get ultra-fast flight right. But it has done so in fits and starts. Now, with China and Russia arguably ahead in this chase, the Trump administration is pouring billions of dollars a year into hypersonic offense and defense.
The Pentagon makes no bones about their purpose.
“Our ultimate goal is, simply, we want to dominate future battlefields,” Mark Lewis, the Pentagon’s director of defense research and engineering for modernization, told reporters in March.
Critics argue that hypersonic weapons would add little to the United States’ ability to deter war. Some think they could ignite a new, destabilizing arms race.
A look at hypersonic weapons:

What’s special about hypersonic?

Two things make these weapons special: speed and maneuverability. Speed brings surprise, and maneuverability creates elusiveness. Together, those qualities could mean trouble for missile defenses.
By generally agreed definition, a hypersonic weapon is one that flies at speeds in excess of Mach 5, or five times the speed of sound. Most American missiles, such as those launched from aircraft to hit other aircraft or ground targets, travel between Mach 1 and Mach 5. READ MORE
