The Sukhoi 57 Russian stealth aircraft is the first, and it was designed to evade detection of F-22 Raptors. The aircraft is equipped with an advanced radar and electronic countermeasure suite. It also includes an ultraviolet missile approach warning system and infrared searching system. These systems allow Su-57 surveillance to continue for a longer duration.
Russia has ordered 76 Su-57 fighters. They are expected to enter service in 2028. They will be used alongside the S-70 Okhotnik drone striker, which will function as a "loyal support man". According to Tass reports, the first flight of the Su-57 modified Su-57 was planned for the middle 2022. This will be followed by trials of a "electric" variant which is expected to take two years.
This aircraft is a fifth-generation fighter, and was originally intended to be used against the F-22. It has a powerful radar and an integrated infrared search system. The Su-57 comes with a 30-mm autocannon.
It is mostly made of titanium alloys and other proprietary Russian metal alloys. It is said to be very maneuverable. The Su-57 can climb at speeds of between 330- 361 meters per minute, with a rate yaw of five degree. This allows it high angles of attack maneuvers and low altitude losses. Moreover, it is able to travel up to Mach 2 without afterburners.
The Su-57 has been designed to serve the Russian Air Force's needs, which require 150-200 multi-role Fighters. If the Su-57 is unavailable, the Air Force may turn to Su-35, a multi-role aircraft that has been extensively employed in operations against UNF or other enemies.
The Su-57 is getting a new engine called the "izdeliye 30," According to reports, the engine can produce thrust of up 16 tonnes. AL-41F-1 is another engine under development. There are plans to replace the hydraulic systems in the Su-57 with electromechanical drives, which will reduce maintenance and improve the aircraft's stealth characteristics.
Russia has been accused recently of using the Su-57 fighter in its fight against Ukraine. Though the United States has publicly denied this accusation, the British Ministry of Defense has confirmed that Russia has used the fighter in Ukraine. Despite not having any official evidence, there have been unconfirmed reports since before June 2022 that suggest the Russian Air Force may still be using the Su-57 fighter in combat.
The UK Ministry of Defence examines the situation in Ukraine. It is currently focusing on Su-57. It has published a Defense Intelligence update on the subject. It stated that the aircraft was likely to be in combat from June 2022 and that the Russians might be planning to execute air-to–air missile strikes into Ukraine. Although all details of this assessment have yet to be made public, it appears that Russians may find the aircraft a suitable fit for their missions. The aircraft's range and sensors are sufficient to match the capabilities the Ukrainian opposition fighters.
