U.S. Completes First Successful SM-3 Block IIA Intercept Test

SACRAMENTO, Calif., Feb. 04, 2017 (GLOBE NEWSWIRE) -- Aerojet Rocketdyne, a subsidiary of Aerojet Rocketdyne Holdings, Inc. (NYSE:AJRD), announced today that its propulsion systems supported the first intercept flight test of Raytheon's Standard Missile-3 Block IIA guided missile.

During the SFTM-01 flight test conducted by the U.S. Navy and Missile Defense Agency, the SM-3 Block IIA interceptor was launched from the USS John Paul Jones (DDG-53).  The intercept test was designed to prove the effectiveness of the larger and faster SM-3 Block IIA variant in intercepting a medium range ballistic missile.

Aerojet Rocketdyne's MK 72 booster provided the first-stage propulsion on the SM-3 Block IIA and the company's Throttling Divert and Attitude Control System (TDACS) maneuvered the kinetic warhead to successfully impact the ballistic missile target.

Aerojet Rocketdyne recently completed a successful altitude test of the Qual-2 TDACS at the company's Sacramento, California, facility in September.  This was the first of two planned qualification tests, and was a pivotal milestone leading to the successful intercept test.

"The SM-3 Block IIA TDACS is the next evolution of the extremely successful SM-3 Block IB TDACS," said Aerojet Rocketdyne CEO and President Eileen Drake.  "The SM-3 Block IIA TDACS allows a significantly greater area to be defended and is more producible."

The SM-3 Block IIA represents the newest generation of U.S. missile defense capabilities and is a key component of the European Phased Adaptive Approach for deployment at-sea and ashore.  Larger rocket motors and key technology improvements increase the area that can be defended by missile defense efforts and increase the probability of intercept against a larger threat set.  With the success of this intercept flight test, the SM-3 Block IIA is on track for deployment on land and at sea in 2018.
