Russia’s Su-57 Stealth Fighter:
The Sukhoi Su-57 is a twin-engine, single-seat, and stealth multirole fifth-generation jet developed for attack operations and air superiority. Its internal name is T-50 and it is the first Russian military aircraft that uses stealth technology. It is intended to be a competition for US military’s Lockheed Martin F-22 Raptor, which is also a fifth-generation stealth fighter that can attack both air and ground targets, while evading the radar. Su-57 has been in development since 2001 and in flight tests since 2010.
In February 2018, Su-57 was successfully tested in Syria in near-combat conditions and for the evaluation of radar and electronic warfare systems.
Some of the main features of the Su-57 are
- Side-facing Cheek-mounted Radars
- Infrared Search and Track
- Directional Infrared Countermeasures System
1. Side-facing Cheek-mounted Radars:
Active Electronically Scanned Array (AESA) radars are mounted below the cockpit on the aircraft’s cheeks. They are secondary radars that act as complementary ones to the aircraft primary N036 Byelka (Squirrel) AESA radar. These are primarily used to provide a greater sensor field of view, thereby, enhancing situational awareness for the pilot. However, another advantage of these radars is that they allow the pilot to accomplish key tactic ‘Beaming’ better than any other fighter. Beaming is when a fighter turns 90 degrees away from an enemy’s pulse doppler radar array and enters the enemy radar’s ‘doppler notch’ without being detected.
2.Infrared Search and Track:
Su-57 has an advanced 101KS ‘Atoll’ infrared search and track (IRST) sensor installed atop of the aircraft’s nose, near its windscreen. This system is used to detect and engage stealth targets from very far distances, without giving off any radio emissions. It is also immune to the effects of electronic warfare and can be used to provide targeting information to a fighter’s missiles in-flight, even while that jet is beaming.
3. Directional Infrared Countermeasures System:
Su-57 not only has a number of missile launch detector apertures on the aircraft but also has turrets, which fire modulated laser beams at an incoming missile’s seeker to blind it and throw it off course. The system used in this multirole aircraft is part of the larger N101KS electro-optical system that includes the Directional Infrared Countermeasures (DIRCM) System turrets, IRST, and the missile launch detector systems that are fixed dorsally behind the cockpit and ventrally under the cockpit.
Apart from these systems 3D Thrust Vectoring, unique weapons bay configuration, and many other features of Su-57, make it a superior fighter. Recently, in May 2018, Su-57 fighter took part in the Aviadarts-2018 army competition and launched a mock attack on ground targets, destroying them. The pair of Su-57 jets attacked a dummy military industrial installation of the mock foe and performed an extremely low flyover, making a sharp turn and engaging the ground targets.
