Aegis SPY1 Radar Upgrade () The Navy plans to equip its new Flight III Aegis destroyers with its new SPY6 radar The SPY6 is made up of 37 selfcontained Radar Module Assemblies (RMAs) The SPY6 is expected be at least 30 times more sensitive than the current Aegis SPY1D radar (or 23 times the detection or tracking rangeAN/SPY1 The AN/SPY1 is the electronically scanned fixedarray radar for the US Navy's Aegis fleet air defence system It operates in the E/FBand, and the output is in several megawattsThe transmitter serves several parallel channels simultaneously The Aegis system has been fully operational since 19 and advanced versions of the radar have also been developedAN / SPY1 Radar Are aircraft carriers now too vulnerable to be useful?
