"At 8:18 pm Hawaiian Standard Time (2:18 a.m. EDT May 10) the target missile was launched from the Pacific Missile Range Facility, located on Kauai, Hawaii. * * * Following target launch, the USS LAKE ERIE detected and tracked the missile with its onboard AN/SPY-1 radar.
"Today’s event * * * was the first successful live fire intercept test of the SM-3 Block IB interceptor and the second-generation Aegis BMD 4.0.1 weapon system. Previous successful intercepts were conducted with the Aegis BMD 3.6.1 weapon system and the SM-3 Block IA interceptor, which are currently operational on U.S. Navy ships deployed across the globe.

("SM-3 Block IB will be deployed in both sea-based and land-based modes as part of phase two of the Phased Adaptive Approach")
My comment:
(a) It says the difference between Standard Missile-3 IB and SM-3 IA is the former introduces advanced sensors (a new, two-color infrared seeker) and a new, highly accurate steering mechanism ("an advanced signal processor and a new Throttleable Divert and Attitude Control System").
(b) There is no need to read the rest of (2) or (3).
