DDG-51 Arleigh Burke - Flight II

Block II ships (DDG 72-78) have the Joint Tactical Information Distribution System (JTIDS) Command and Control Processor, Combat Direction Finding, the Tactical Information Exchange System (TADIX B), SLQ-32(V)3, and the capability to launch and control the SM-2 Block IV Extended Range Missile added. Some 24 Block I and II ships may later be equipped to operate drone surveillance vehicles. The Navy expects to upgrade DDG 51-78 with CEC, the baseline 6 version of the Aegis weapon system, an upgraded Standard Missile II variant, and NULKA. The Navy expects these upgrades to give these ships a high capability against both the near- and mid-term threat requirements and moderate capability against the far-term threat requirement.
