Su-57

The Su-57 took off for its first flight on January 29, 2010 in Komsomolsk-on-Amur. The first flight model of the fighter and a full ground test bed used for the testing of equipment and systems in support of the flight testing program were delivered to the JSC Sukhoi DB flight testing-and-development facility in the Town of Zhukovsky near Moscow on April 8. Upon completion of the required system and component-bed testing, including strength tests on the static airplane, ground testing of the test bed airplane and flight model, flight tests of the airplane under the preliminary testing program started on April 29, 2010.

The second flight model took off for its first flight at the Komsomolsk-on-Amur production site (KnAAZ) on March 3, 2011. After the completion of factory tests, it was included in the preliminary testing program.

The third flight model made its first flight on November 22, 2011. After the completion of a set of ground preparation works and re-equipment with an extended set of on-board equipment, it also entered the preliminary testing program.

The fourth and fifth Su-57 flight models arrived at Zhukovsky airfield near Moscow on January 17, 2013 and November 20, 2013. The airplanes arrived from the Far East under their own power.

Good stability and handling performance has been achieved at subsonic and supersonic speeds, at low and high altitudes, and at post-stall angles of attack. Avionics tests are in progress. Fight refueling and examination of the airplane’s behavior in different configurations have been successfully completed.
Main flight testing objectives at the current stage are the testing of combat system-operating modes, interfacing with weapons, and the use of weapons.

The maiden flight of Sukhoi Su-57 took place on January 29, 2010.

The production of Su-57 prototypes was completed in 2017 as part of the work to create the 5th generation aviation complex and its systems.

Tests were performed on all Su-57 components. Flight performance specified in the tactical and technical assignment, as well as the parameters of the avionics, weapons complex and low visibility, including during real combat operations have been confirmed.

The results of the experimental work carried out allow to consider the aircraft to be the best in its class.

Tests of a new generation engine with reduced specific fuel consumption and increased thrust, which will later be installed on production aircraft, have begun on the Su-57–2 flying laboratory.

In 2018, the Russian Defense Ministry signed the first contract for supply of an initial batch of Su-57 fighters.

Su-57 serial production has begun, and the first aircraft of the initial batch was delivered to the Ministry of Defense of the Russian Federation in 2020.

Su-57 is currently Sukhoi’s most advanced aircraft in the model lineup. Its export version in the future will become one of the main products of the company in the aviation equipment market.

Su-57 has a number of unique features, combining the functions of a fighter and a strike aircraft. This fifth-generation aircraft is equipped with a fundamentally new complex of deeply integrated avionics, which has a high level of automation for combat use and intelligent crew support.

The aircraft’s on-board equipment allows it to perform tasks not only autonomously, but also to exchange data in real time, both with ground control systems and as part of a task force.

The aircraft can use a wide range of air-to-air and air-to-surface munitions, allowing it to perform both fighter and strike tasks.

Su-57 has the ability to carry out covert actions, due to low level of visibility in radar, infrared and visible wavelength ranges.

Su-57’s auxiliary power unit provides high deployment autonomy, reduced fuel consumption during ground testing and saving the life of main engines. The use of an on-board oxygen extraction unit also ensures high autonomy of the aircraft operation. The use of an explosion-proof fuel tank system on the aircraft, made as a generator-type neutral gas system makes it possible in combination with other measures to implement the aircraft’s high level of combat survivability.

The Su-57 aircraft has a level of combat effectiveness that surpasses foreign analogues at a lower life cycle cost due to the combination of high maneuverability and super maneuverability with capability of supersonic cruising flight, a modern complex of avionics, a complex of aviation weapons and low visibility
