"This is the first flight test of the Arrow 3 interceptor and was conducted at an Israeli test range over the Mediterranean Sea," according to the Israeli Defense Ministry. "Israel's Missile Defense Organization and U.S. Missile Defense Agency officials conducted the flight test."
The developmental weapon is intended to destroy incoming enemy ballistic missiles beyond Earth's atmosphere.
"The Arrow 3 is the upper tier for exoatmospheric interceptions to provide the state of Israel additional opportunities for interception of incoming missiles from Iran or elsewhere," the ministry said.
The exercise was "100 percent successful," a ministry source told Reuters.
The radar is to be installed at a military base along the Sea of Japan, according to local news reports. It could be aimed at helping to counter any North Korean missile that crosses above west or central Japan on its way toward Guam or Hawaii, according to Kyodo News.
