Turkish Aerospace Industries is currently producing 30 T129 ATAK helicopter gunships for Pakistan but have hit a snag in the process. In order to go further with the contract, Turkey needs U.S. export licenses, which the U.S. is threatening to not give. This comes after Washington sanctioned two Turkish ministers. This lead to Turkey sanctioning two U.S. secretaries.  The argument means that the $1.5 billion deal is on the line, reports Defence News.
