Pricey stealth-fighter finally useful? US defence contractors have carried out the first flight tests in which America's latest cutting-edge fighter targeting radars have been put to novel use - as high-capacity wireless datalinks. This crafty use of existing hardware has the potential to ease military bandwidth bottlenecks, and could offer a chance for expensive superfighters to be of use even in the absence of serious aerial opposition.â¦
