Abstract: The US Navy and Japan are working together in intercepting ballistic missiles through practicing with the Aegis Ashore ballistic missile defense system. This is in response to threats of ICBMS being tested by North Korea. This helps ensure security with the US’s Asia Pacific region allies. This test was successful against medium and intermediate range ballistic missiles.
From a Missile Defense Agency News Release
The SM-3 Block IIA is being developed cooperatively by the United States and Japan to defeat medium- and intermediate-range ballistic missiles. The SM-3 Block IIA interceptor operates as part of the Aegis Ballistic Missile Defense system and can be launched from Aegis-equipped ships or Aegis Ashore sites.
At approximately 10:30 p.m., Hawaii Standard Time, Feb. 3 — 3:30 a.m. EDT, Feb. 4 — a medium-range ballistic missile target was launched from the Pacific Missile Range Facility at Kauai, Hawaii. The crew of the John Paul Jones detected and tracked the target missile with its onboard 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, which intercepted the target.
“[The] test demonstrates a critical milestone in the cooperative development of the SM-3 Block IIA missile,” said MDA Director Navy Vice Adm. Jim Syring. “The missile, developed jointly by a Japanese and U.S. government and industry team, is vitally important to both our nations and will ultimately improve our ability to defend against increasing ballistic missile threats around the world.”
Based on preliminary data the test met its primary objective. Program officials will continue to evaluate system performance based upon telemetry and other data obtained during the test.
The flight test, designated SM-3 Block IIA Cooperative Development Project Flight Test, Standard Missile-01, was the third flight test of the SM-3 Block IIA guided missile, and the first intercept test. This test also marks the first time an SM-3IIA was launched from an Aegis ship and the first intercept engagement using the Aegis Baseline 9.C2 (BMD 5.1) weapon system.
Aegis Ballistic Missile Defense is the naval component of the U.S. Ballistic Missile Defense System. The MDA and the U.S. Navy cooperatively manage the Aegis BMD program. The Missile Defense Agency’s mission is to develop and deploy a layered Ballistic Missile Defense System to defend the United States, its deployed forces, allies and friends from ballistic missile attacks of all ranges in all phases of flight.
