The United States on Sunday conducted a "successful" a test of its Terminal High Altitude Area Defense system, military officials said.

The test comes two days after North Korea launched its second intercontinental ballistic missile.

According to the U.S. Missile Defense Agency, a U.S. Air Force plane fired a ballistic missile over the Pacific Ocean in Alaska and it was then intercepted by the system.

"In addition to successfully intercepting the target, the data collected will allow MDA to enhance the THAAD weapon system, our modeling and simulation capabilities, and our ability to stay ahead of the evolving threat," said MDA Director Lt. Gen. Sam Greaves in a statement.

The THAAD system, which is primarily contracted by Lockheed Martin Company, is a ground-based defense system designed to shoot down short, medium and intermediate range ballistic missiles.

On Saturday, South Korean President Moon Jae-in ordered discussions to be held with the U.S. on deploying additional THAAD anti-missile defense units following North Korea's test launch.

There are currently two THAAD units deployed by the military in southern South Korea.

According to U.S. military officials, Sunday's test was the 15th successful intercept in 15 tests for THAAD.
