Su-57s sound: Many people in Russia heard a mysterious scary sound like a wolf howl while four Su-57 fighter jets flew during a rehearsal of the Victory Day Parade in Moscow

According to the TASS, the fifth-generation Sukhoi Su-57 fighter jet is designed for destroying any type of air and surface targets.

The Su-57 is intended to be a fifth-generation multirole fighter aircraft and the first operational stealth aircraft for the Russian Air Force.

Most information about the aircraft is classified for now but sources within the Sukhoi company and Defence Ministry have openly stated that the aircraft is to be stealthy, supermaneuverable, have supercruise capability, incorporate substantial amounts of composite materials, and possess advanced avionics such as active phased-array radar and sensor fusion to overcome the previous generation fighter aircraft as well as ground and naval defences.

The Su-57 is planned to be the first operational aircraft in the Russian Air Force service to use stealth technology.
