🇷🇺️ - According to Rostec, the Su-57E (T-50-9) flew to Egypt for the Al Alamein International Airshow relying only on its internal fuel tanks located in the main interior bays of the aircraft, rather than conventional external drop tanks.
Rostec says that after one stopover, the plane still had enough fuel to fly another 1,000 km and conduct a demonstration flight the next day.
