A Russian Su-57 Felon next-generation fighter sharing the tarmac with a U.S.-made F-35 stealth fighter is a truly unusual sight, and it has quickly become a signature image of the Aero India 2025 international Air Show.

Earlier, it was reported that the U.S. Air Force had abruptly pulled its planned flight demos for both the F-35 and F-16 at the Air Show.

But in a surprise twist, the U.S. Air Force flew the F-35 at the Air Show, fuelling speculation about why the U.S. decided to take the F-35 to the skies, according to a report by Indian news media Indian Express.

The Defence Ministry had said in a statement that: “It marks a milestone in global defence collaboration and technological advancement, offering aviation enthusiasts and defence experts an unparalleled prospect to witness these state-of-the-art warplanes.”

The F-35's strengths lie in its stealth capabilities and ability to integrate into networked warfare environments, but it is often criticised for its kinematic performance. In contrast, the Su-57 is a formidable opponent in dogfights, utilizing powerful 3D thrust-vectoring engines to execute impressive low-speed manoeuvres. With planned engine upgrades for future models, the Su-57 aims to improve its supercruise performance, narrowing the performance gap with Western fighters.

In close-range combat scenarios, NATO exercises suggest that fourth-generation fighters with high manoeuvrability, such as the F-16 and F/A-18, maintain an edge over the F-35.

NATO combat training exercises and simulated dogfights indicate that the F-35 is outperformed in visual range engagements by highly manoeuvrable fourth-generation fighters like the F-16 and F/A-18. Despite the F-35's advanced technology, NATO's simulated dogfights and combat training exercises reveal that highly manoeuvrable fourth-generation fighters such as the F-16 and F/A-18 are superior in visual-range engagements.

While the F-35 possesses many advantages, NATO exercises have demonstrated that it cannot outperform the F-16 and F/A-18 in visual-range dogfights due to their superior manoeuvrability. The F-35 may struggle against more agile fourth-generation fighters like the F-16 and F/A-18 in a dogfight, according to simulated combat training exercises held by NATO allies.

The Aero India 2025 air show in Bangalore featured the first-ever joint appearance of the Russian Su-57 and the American F-35 Lightning-II fighter jets. According to the Ministry of Defence, the inclusion of both aircraft underscores India's importance as a hub for international defence and aerospace collaboration and provides a valuable comparison of Eastern and Western fifth-generation fighter technology.

The appearance of the Su-57 marked its debut at Aero India, while the F-35, manufactured by Lockheed Martin, had been showcased at previous editions.

Both aircraft performed aerial displays, demonstrating their capabilities. The Su-57, piloted by Russian test pilot Sergey Bogdan, showcased its manoeuvrability and agility. The F-35 was flown by Major Justin ‘Scout’.

Described as Russia's premier stealth multi-role fighter, designed for air superiority and strike capabilities. It features advanced avionics, supercruise capability, and stealth technology. The Su-57 is equipped with the N036 Byelka radar and Irbis-E infrared search and track system, and its aero-engines provide thrust vectoring for exceptional agility.

Lockheed Martin's fifth-generation fighter integrates advanced stealth, situational awareness, and networked combat capabilities.

The presence of both the Su-57 and F-35 at Aero India 2025 allowed experts and enthusiasts to witness these state-of-the-art warplanes and compare their capabilities.

Conclusion

The presence of both the Russian Su-57 and the U.S. F-35 Lightning II at Aero India 2025 is a significant event. The US deciding to fly the F-35 though not exactly a forced reaction, but more of a competitive opportunity to outclass the Russian stealth jet.

Aero India 2025 marks the first time that the Su-57 and F-35, both advanced fifth-generation stealth fighters, are present at the same event in India.

Both aircraft are vying for India's attention as the country seeks to bridge its fifth-generation fighter gap. The U.S. is also aiming to counter Russia's long-standing dominance in India's defence market.
