Exoatmospheric.

This is coolbert:

"'This test demonstrates that the US ballistic missile defense system is operational, reliable, and ready to protect the country,' . . . 'Raytheon kill vehicles have now successfully completed nearly 50 space intercepts, which underscores our expertise and ability to design and develop these systems to defeat the evolving threat.'" - Wes Kremer, president of Raytheon.

ONLY good for ballistic missiles of the intermediate range? The bullet can hit a bullet?

"Raytheon's Exoatmospheric Kill Vehicle Defeats Ballistic Missile in Test Over Pacific"

From https://www.zerohedge.com | the article by TYLER DURDEN | DEC 11, 2023.

"Raytheon has successfully tested its 'Exoatmospheric Kill Vehicle,' designed to defend the US by intercepting and neutralizing long-range ballistic missiles in low-Earth orbit."

"The kinetic-force weapon successfully destroyed an intermediate-range ballistic missile during a test in the Pacific region by the US Missile Defense Agency and the US Northern Command on Monday."

American interceptor able to counter and destroy hypersonic or intercontinental-ballistic missiles as well?

That remains to be seen!
