Electronic Combat.

The article reports on the competition among sensor companies to generate next-generation airborne radar. Aerospace industry and U.S. Defense Department experts say the electronic equivalent of the automotive engine industry competition has emerged. John Fagnant of Northrop Grumman says the active, electronically scanned array (AESA) is a multifunction radio-frequency system that supports many mission functions, only one of which is radar. It is stated that the competition is intensifying as the aircraft needing the new radars multiply.
