Speed is undoubtedly the new stealth and the Pentagon's top weapons supplier just got one step closer to handing hypersonic weapons to the U.S. Air Force.

Lockheed Martin secured a $928 million contract to build an undefined number of hypersonic conventional strike weapons, the Pentagon said Wednesday in a statement.

Per the multimillion-dollar contract, Lockheed will be responsible for designing, engineering, weapon integration and logistical support.

The development will take place in the northern Alabama city of Huntsville which is dubbed the "Rocket City" as it was the birthplace of America's rocket program.

A hypersonic weapon is a missile that travels at Mach 5 or higher, which is at least five times faster than the speed of sound. That means a hypersonic weapon can travel about one mile per second.
