China’s updated sixth-generation fighter jets put US on notice for air supremacy
Notable changes seen in prototypes just 10 months after their first public appearance, suggesting ‘accelerated’ progress towards production

Notable changes have been observed in both of China’s sixth-generation fighter programmes, with updated prototypes seen flying just 10 months after their first public appearance, indicating rapid progress as the country vies with the US for air supremacy.
Unofficially referred to as the J-36, the aircraft is believed to be the second prototype, featuring significant upgrades such as angular exhaust nozzles replacing the recessed exhausts seen on the earlier version.
According to a report by The War Zone, an online news publication, the angular exhausts may help resolve stability and manoeuvrability issues during certain flight phases.
