The Su-57 just became deadlier.
Here's What You Need to Remember: The upgraded K-77M also has a new dual-pulse rocket motor and an enhanced active electronically-scanned array radar seeker. It has double the range—upwards of 100 miles—of the original R-77, and could also be capable of engaging anti-aircraft missiles including those approaching from the rear.
Photos circulated online earlier this week showing a Russian Su-57 Felon flying without its canopy during a test sortie. The aircraft was part of the Russian Aerospace Forces (RuASF) 929th V.P. Chkalova State Flight Test Center from Akhtubinsk Air Base, which is responsible for the state evaluation of military aircraft as well as weapons platforms.
