Let's hope a decision on an alternative platform is made quickly (although I am sceptical due to the bureaucratic maze of NATO procurement). The current AWACS-platform (E-3A) still uses old engines which are loud, smokey and not as efficient. Neighbouring communities deserve a quieter platform as well as NATO needs a potent airborne early warning platform. European technology is not an issue (Thales, Leonardo etc. make great modern AESA based radars). Also interoperability of data between NATO members used in the C2 chain is not an issue.
