And these interceptors—no longer constrained by the range of the Aegis radar to detect an incoming missile—can be launched sooner and fly farther. Existing Aegis BMD–equipped ships already embody the LoR capability, as demonstrated by the 25th Aegis BMD flight test FTM-15 on April 15, 2011. This was the first LoR test of the system against an As part of EPAA Phase II, Aegis Ashore The C2BMC application relies on the intermediate-range “separating target”— is a relocatable, land-based Aegis BMD Link 16 tactical data exchange network to a warhead separating from its booster system that, together with the shipboard ensure that sensor and shooter systems have missile.
