The Turkish Air Force will begin considering other options to meet its cargo requirements if the Airbus A400M military transporter programme collapses in the next week, military officials said.
Turkey is one of the seven nations that have ordered the Airbus A400M military transport plane, and planned to purchase a total of ten planes.
The seven nations last week failed to resolve differences over sharing billions of euros in cost overruns and are expected to meet this week to come to a conclusion before a 31 January deadline.
Other options to meet the air force's cargo aircraft requirements include Lockheed Martin's C-130J, the most modern in the C130 family of cargo planes and Alenia's C-27J transport plane, according to hurriyetdailynews.com.
The seven customer nations of the A400 consortium are Germany, France, Spain, the UK, Turkey, Belgium and Luxembourg.
Turkish Aerospace Industries will manufacture parts of the A400 plane altogether worth $750m throughout the project's lifespan if a solution is found for the project before the deadline.
At present, the Turkish Air Force has 19 older European-made C-160s to be replaced by the A400.
The Airbus A400M is a four-engine turboprop military transport aircraft specifically designed to replace tactical airlifters.
