An executive from Avio, which is part of the Eurojet consortium, says the installation of AESA radar to the Eurofighter requires an upgrade to the aircraft’s nozzles as well.
“Placing an [AESA] radar in the nose of the aircraft will add weight to the front of the aircraft,” he said. “The center of gravity of the aircraft moves forward and to counterbalance this you can either put dead weight further back, or a clever weight.”
