JPJ號在去年12月試射SM-6 Dual I（防空/反彈道雙用版）時，她的神盾系統還是基線9.C1，現在就更新成9.C2了⋯⋯。也即是代表，JPJ號已經加入了NIFC-CA（海軍整合火控－防空）計劃的增量2（Increment 2），發揮與其他平台（F-35、P-8A海洋巡邏機及MQ-4C廣域海上監控無人機等）進行聯合作戰的能力。
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. Eastern Daylight Time, Feb. 4) a medium-range ballistic missile target was launched from the Pacific Missile Range Facility at Kauai, Hawaii. John Paul Jones detected and tracked the target missile with its onboard AN/SPY-1D(V) 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.
