US says F-47 will be first sixth-gen jet. China's J-36 and J-50 are already flying
A senior U.S. Air Force official said the F-47 next-generation fighter is approaching production and could fly during the current presidential term, while Chinese J-36 and J-50 prototype aircraft have already appeared in flight testing. The comparison highlights differing public timelines in the U.S.-China race to field sixth-generation air combat systems. However, design details, test objectives, readiness, and production status remain highly classified or unconfirmed, and the Chinese designations are unofficial labels used by observers. Visible prototype flights do not establish operational capability or an overall technological lead.
