American media reported Wednesday that a test of an SM-3 Block IIA launched from an Aegis Ashore missile defense installation was unsuccessful.
Sources who spoke on condition of anonymity said that the anti-missile SM-3 was launched from an installation on Hawaii but failed to interdict an incoming dummy missile fired from an aircraft.
It wasn’t clear why the test failed but the Pentagon is analyzing the test results.
The SM-3 is being developed by Raytheon in conjunction with Japan.
The Missile Defense Agency confirmed a test but did not discuss the results.
“The Missile Defense Agency and U.S. Navy sailors manning the Aegis Ashore Missile Defense Test Complex (AAMDTC) conducted a live-fire missile flight test using a Standard-Missile (SM)-3 Block IIA missile launched from the Pacific Missile Range Facility, Kauai, Hawaii, Wednesday morning,” Mark Wright, a spokesman for the agency, said.
Another test failed last June, but there was a successful test in 2017. [source]
