According to the British intelligence reports, Russian
Aerospace Forces have been using a few Su-57 (NATO Reporting Name: Felon)
aircraft for months. Platforms are missioned to deploy long-range missile
strike attacks.
British officials claim that the Russian side is afraid of
Su-57's being shot down. Because of this reason, platforms are believed to have
only seen close combat over Ukrainian air space now. On the other hand,
American press reports say that the Su-57 has yet to enter the use of any
Russian combat aviation formation, although the Russian Ministry of Defence
took delivery of some aircraft.
It is known that NATO and British aircraft continuously
conduct Intelligence, Surveillance and Reconnaissance (ISR) flights near the
Ukrainian warzone with different aircraft. These tasks aim to provide Ukrainian
defenders command, control and intelligence support. According to Western
claims, Felons may be deployed for limited test purposes over Ukraine.
