Germany has decided it will not purchase Euro Hawk reconaissance drones because meeting the standards required to win aviation approval would cost 500 million to 600 million euros, Reuters reported on Tuesday.
Even if it committed such funds, there would be no guarantee of securing final approval, the report added.
German armed forces currently operate one prototype Euro Hawk and were considering to buy four drones from EADS and Northrop Grumman.
Germany had earmarked 1.2 billion euros for the purchase and development of the drones, the report said.
