We spent a day with THAAD, the world's most advanced missile system that has North Korea spooked

The most advanced missile system on the planet can hunt and blast incoming missiles right out of the sky with a 100% success rate - and we spent a day with it.

Meet America's THAAD system.

THAAD (Terminal High Altitude Area Defense) is a unique missile-defense system with unmatched precision, capable of countering threats around the world with its mobility and strategic battery-unit placement.

"It is the most technically advanced missile-defense system in the world," US Army Col. Alan Wiernicki, former commander of the 11th Air Defense Artillery Brigade, told Business Insider in an interview.

"Combatant commanders and our allies know this, which puts our THAAD Batteries in very high global demand," Wiernicki added.

And that demand seems poised to rise following North Korea's fifth and largest nuclear test last week.
