The new Russian fifth-generation fighter was tested by firing from a cannon. Earlier, the Aerospace Forces received the first production aircraft.
The date and place of the tests shown in the video are unknown: first, the eight-second video appeared on Telegram, and then it was posted on YouTube.
As you can see, the unpainted Su-57 is firing from the improved 30mm GSh-30-1 cannon, also known as the 9-A-4071K. Its first tests, according to data from open sources, were carried out in 2014. The single-barreled gun is located in the front right part of the aircraft fuselage.

Let us remind you that we could take a closer look at the first (actually the second) production Su-57 fighter in December last year, when the aircraft was handed over to the Aerospace Forces. In total, under the contract from 2019, 76 serial fighters are to be handed over to the military.
Now the Su-57 is being tested with various weapon systems. One of the most significant events in this regard was the tests of a promising hypersonic system. The missiles will be compact, with the possibility of placing the Su-57 inside the fuselage.
