Bulgaria's defence ministry said that the U.S. has submitted an offer for delivery of eight F-16 Block 70 fighter jets along with ordnance, maintenance systems and personnel training. The offer is due to be officially finalised and submitted for approval by the Bulgarian government, the defence ministry said in a statement on Monday. The ministry did not disclose any details about the offer, including the price, which is expected to substantially exceed the originally planned budget of 1.8 billion levs ($1.0 billion/920 million euro). Earlier this month, Bulgaria's defence ministry said that it expects to receive a letter of agreement (LOA) from the U.S. for the purchase of eight F-16 Block 70 fighter jets for a total of some $1.2 billion. At the time, the U.S. Defence Security Cooperation Agency said that the State Department has made a determination approving a possible sale of F-16C/D Block 70/72 aircraft with support for an estimated cost of $1.673 billion.
