Sukhoi Su-30, Fifth Generation Su-57 “Felon” to Receive More Powerful New Engines

(DEFENCE SECURITY ASIA) — Sukhoi Su-30 fighter jets are reportedly set to receive new engines to enhance their performance, making them comparable to newer fighters such as the Sukhoi Su-35 and the fifth-generation Su-57 “Felon.”

According to Oleg Pankov, the chief designer of the Su-30, starting in 2025, these jets will be equipped with AL-41-FSI engines, similar to those used by the Su-35 and Su-57.

Currently, the Russian Air Force’s Su-30SM variant is already utilizing the AL-41-FSI engine.

This new engine represents a significant capability upgrade over the current AL-31FP engine, providing a 16 percent increase in maximum thrust to 14,500 kilogram-force (kgf) and extending service life to 4,000 hours while maintaining the same weight and dimensions.

The AL-41-FSI engine will enhance electrical power generation, enabling the integration of more powerful radar and electronic warfare systems, as seen in the Su-30SM.

 

Russian media sources indicate that the new engine will allow Su-30 jets to be equipped with the high-powered “Irbis” radar, which can detect ground, sea, and air targets at greater distances.

Analysts note that the Su-30SM and will be followed by original variant of Su-30 to be equipped with the AL-41-FSI engine can operate various weapon systems, including air-to-ground missiles, air-to-air missiles, KAB-250 glide bombs, and X-59MK2 air-to-ground missiles.

While the Su-57 currently uses the same AL-41-FSI engine as the Su-35 and Su-30SM, it is also set to receive a new engine starting this year.

According to Russian defense media, the new engine for the Su-57 has passed all tests, demonstrating thrust of 11,000 kg and afterburner thrust of 18,000 kg.

With this engine upgrade, the Su-57 can now achieve a cruising speed of Mach 2.

 

Beginning this year, United Aviation Corporation (UAC) will start delivering upgraded Su-57 jets, known as the Su-57M (Modification), to the Russian Aerospace Forces.

 These jets will feature the new AL-51F1 engine, formerly known as “Izdelie 30.”

The AL-51F engine solidifies the Su-57’s status as a fifth-generation fighter jet.

Additionally, UAC has reportedly introduced more artificial intelligence (AI) systems to the Su-57, enhancing its capabilities as a next-generation fighter.

 The company recently announced its readiness to equip the Su-57 with a new fifth-generation short-range air-to-air missile.

The fifth-generation short-range air-to-air missile, known as “RVV-MD2,” was unveiled by Moscow-based company GosMKB Vympel.

Renowned for producing various missile systems, Vympel claims the “RVV-MD2” is five to ten years ahead of Western counterparts and is now in production. — DSA
