The Sukhoi 57 Russian stealth jet fighter was the first designed to evade detection and capture F-22 Raptors. The aircraft is equipped with an advanced radar and electronic countermeasure suite. It also features an infrared search system and ultraviolet missile approach warning system. These systems enable the Su-57's radar surveillance to last for longer periods of time.
Russia has ordered 76 Su-57 fighters. They should be operational by 2028. They will be used together with the S-70 Okhotnik strikedron, which will serve as a "loyal wingsman". According to Tass, Su-57's first flight was expected to be in the middle to 2022. Trials of an "electric" Su-57 variant will follow, and are expected to last for two years.
This fifth-generation fighter aircraft was designed originally to fight the F-22. It has a powerful radar and an integrated infrared search system. The Su-57 also has a 30mm 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 between 33 and 361 m per second. It also has a rate for yaw which is five degrees. This allows it perform high angles with attack maneuvers while sustaining minimal altitude loss. It can travel up Mach 2 without needing to use afterburners.
The Su-57 was developed to meet the needs and requirements of the Russian Air Force. This force requires 150-200 multi-role aircraft 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," It can generate thrust up to 16 tonnes, according to reports. The AL-41F-1 engine is another in development. It is being considered to replace the hydraulic systems of the Su-57 with electronic drives. This will lower maintenance costs and increase stealth.
Russia has been accused, in recent months. of using Su-57 against Ukraine. Although the United States denies this accusation, it has been confirmed by the British Ministry of Defense that Russia used the Su-57 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 is examining the situation in Ukraine, and is focusing on the Su-57. It has published a Defense Intelligence update on the subject. According to it, the Russians are likely to have the aircraft in combat by June 2022. They may also plan to attack Ukraine with air-to–air and missile missiles. The details of this assessment are not known, but it appears that the aircraft might be a good fit to carry out Russian missions. Its range and sensor capabilities are more then enough to match those of the Ukrainian opposition fighters.
