WASHINGTON (CNN) -- A U.S. warship has successfully knocked down a short-range missile fired from Hawaii, the Pentagon has said, amid global concerns about a possible North Korea missile test.

An interceptor rocket fired from the cruiser USS Shiloh knocked down the warhead from a target missile about 250 miles off Kauai shortly after noon (6 p.m. ET), the Defense Department's missile defense agency reported on Thursday.

The U.S. missile defense agency said Thursday's test had been scheduled for months and was not prompted by indications that North Korea was planning to test launch a long-range missile, AP reported.

The latest test of the U.S. missile defense program is the seventh time in eight attempts the military has successfully shot down a target with a ship-based interceptor, the Pentagon said.

A Japanese warship took part in the exercise, using its radar to track the test missile, the Pentagon said.

It is the first time a U.S. ally has taken part in a sea-based missile defense test after Tokyo agreed to develop missile defense technology with America last year.

Tokyo became interested in developing the technology after North Korea last test-fired a missile, firing it over Japan's main island, according to The Associated Press.

The North Koreans fired the Taepodong-1 missile in 1998, but declared a moratorium on future tests in 1999
