Greek media estimate the deal at over €1.2 billion ($1.76 billion). However, the Greek General Staff has refused to confirm the report. The purchase would be one of the largest arms deals between Russia and a NATO member state. In the 1990s, Greece acquired over $1 billion worth of Russian weapons. Russian Air Defense system TOR-M1, Kornet and Fagot antitank weapons are in service with the Greek Armed Forces. Greek Prime Minister Costas Karamanlis is set to visit Russia on December 17-19.
