GERMANY - Germany has come under fire for its decision to drop the F-35 stealth fighter as part of the upgrade of its airforce. The decision was seen as a big setback for Lockheed, the top US arms maker, which had hoped to add to recent F-35 sales to other European countries, including Belgium. Its European vice-president Jonathan Hoyle said Berlin’s failure to opt for the F-35 had raised concerns among allies and prompted the question: “What does it mean for NATO?” Germany will pick either the Eurofighter or Boeing’s F/A-18 fighter jet to replace its ageing fleet of Tornado warplanes.
