June 21, 2017 – The U.S. Missile Defense Agency and the Japan Ministry of Defense conducted a development flight test today of a new Standard Missile-3 (SM-3) Block IIA missile off the coast of Hawaii.
A planned intercept was not achieved.
The SM-3 Block IIA is being developed cooperatively by the U.S. and Japan to defeat medium- and intermediate-range ballistic missiles. This is a new, developmental interceptor that is not yet fielded by either country.
At approximately 7:20 p.m., Hawaii Standard Time, June 21 (1:20 a.m. Eastern Daylight Time, June 22), a medium-range ballistic target missile was launched from the Pacific Missile Range Facility at Kauai, Hawaii. The USS John Paul Jones (DDG 53) detected and tracked the target missile with its onboard AN/SPY-1 radar using the Aegis Baseline 9.C2 weapon system. Upon acquiring and tracking the target, the ship launched an SM-3 Block IIA guided missile, but the missile did not intercept the target.
Program officials will conduct an extensive analysis of the test data. Until that review is complete, no additional details will be available.
This was the fourth development flight test using an SM-3 IIA missile, and the second intercept test. The previous intercept test, conducted in February 2017, was successful.
Though currently still in the development and test phase, the SM-3 Block IIA interceptor is being designed to operate as part of the Aegis Ballistic Missile Defense system. Currently, the Aegis BMD system operates with the SM-3 Block 1A, SM-3 Block 1B, and SM-6 interceptors.
