Sukhoi Su-57
The Sukhoi Su-57 (Russian: Сухой Су-57; NATO reporting name: Felon) is a twin-engine stealth multirole fighter aircraft developed by Sukhoi. It is the product of the PAK FA (Russian: ПАК ФА, prospective aeronautical complex of front-line aviation) programme, which was initiated in 1999 as a more modern and affordable alternative to the MFI (Mikoyan Project 1.44/1.42). Sukhoi’s internal designation for the aircraft is T-50. The Su-57 is the first aircraft in Russian military service designed with stealth technology and is intended to be the basis for a family of stealth combat aircraft.
A multirole fighter capable of aerial combat as well as ground and maritime strike, the Su-57 incorporates stealth, supermaneuverability, supercruise, integrated avionics and large payload capacity.
On 25 December 2020, the Russian Defence Ministry announced that the Su-57 had entered service upon the delivery of the first production aircraft to one of the aviation regiments of the Southern Military District at Lipetsk air base. This initial production batch would be used for military evaluation, tactics development, and crew conversion training.
