Greece’s security council, KYSEA, approved on Monday the purchase of a three-billion euro multi-layer air and drone defence system and the upgrade of 38 F-16 fighter jets, the country’s Defence minister said on Monday.

The total cost for the two projects, that were approved by a Greek parliamentary committee earlier in the month, was estimated at about 4 billion euros ($4.61 billion).

Greece is already in talks with Israel to provide a big part of the missile systems for its air and drone defence dome, called “Achilles Shield”.

“KYSEA also approved the upgrade of four MEKO 200 frigates and a maintenance agreement for C29J military transport aircraft,” said defence minister Nikos Dendias.
