Russia has unveiled its first fleet of supersonic stealth fighter jets which are so advanced that they appear INVISIBLE to enemies.
The Sukhoi-57 is said to rival the American F-22 and Chinese Chengdu J-20 and Shenyang J-31 combat planes.
The country's air force chief Viktor Bondarev told Russian defence TV channel Zvezda Russia's first fifth-generation fighter jet will be known as the Su-57.
The aircraft was dubbed ‘PAK FA’ and ‘T-50’ during development.
Mr Bondarev told Zvezda: " The decision has been taken, the plane has been christened. Su-57 is what we are going to call it now," the Tass agency reported.
