The US State Department has approved a possible military sale to Greece of Chinook helicopters at an estimated cost of  $150 million, according to a statement by the Defense, Security,Cooperation Agency (DSCA), which said it had delivered the required certification notifying Congress of the possible sale.

This notice of a potential sale of these helicopters and support is required by law and does not mean the sale has been concluded while “it will not alter the basic military balance in the region.”
