Although AESA has many benefits over passive arrays and older tube-based systems, the comparison and claims against these older architectures has been shown to be false over life cycles of Navy radar systems. These AESA systems are not more reliable, and contrary to the anti high-voltage verbiage, AESA has replaced that subsystem with many high current power supplies and created other issues in reliability. Thermal gradients, temporal calibration issues, etc. continue to plague these systems. There are fleas on all system approaches ... and we have not even started to discuss initial cost versus life-time and maintainability.
