Su-57 DLC Akula addon - Ace Combat 7: Skies Unknown

"A special version of the Su-57 which resembles the aircraft flown by a mercenary known as "Akula".
Turning performance has been further improved and it is equipped with PLSL, resulting in a highly maneuverable fighter capable of inflicting major damage to its enemies.
The pilot of this aircraft received a hero's medal while he was enlisted in the Russian Air Force, but he gave up his country for revenge.
People who have seen the Sharkmouth flying in the sky have been said to have sensed a feeling of madness."
