Greece has issued an order for 18 Dassault Rafale fighter planes, 12 that will be secondhand from the French air force (to be replaced by newer models for France's inventory) to be supplied ASAP, and 6 brand new speculated to be the most recent mark with better long range missile capabilities.
Greece already has some Mirage 2000 so there's history there, but I would imagine buying French systems which are mostly proprietary AFAIK, and thus more opaque to the US / NATO / Turkey certainly was a consideration.
