The Indian Air Force (IAF), recognized as the fourth largest air force globally, is currently without a fifth-generation fighter jet. Despite previous involvement in the Sukhoi/HAL Fifth Generation Fighter Aircraft (FGFA) project, which was based on Russia's Sukhoi Su-57, India withdrew from the program in 2018. However, the possibility of revisiting this decision remains open.
Globally, 19 countries operate fifth-generation fighters. China uses its Chengdu J-20 ‘Mighty Dragon,’ while Russia employs the Sukhoi Su-57 ‘Felon.’ Seventeen other nations have adopted the Lockheed Martin F-35 Lightning II, with the U.S. exclusively operating the F-22 Raptor. Only the U.S., China, and Russia have developed original fifth-generation fighters, though many nations participate in F-35 development.
The FGFA project aimed to integrate 43 enhancements proposed by India into the Su-57, including advanced sensors and avionics. The Indian variant was planned to be a two-seater, featuring a pilot and a weapon systems operator (WSO). Since stepping away from FGFA, India has focused on developing its own fifth-generation fighter, the Advanced Medium Combat Aircraft (AMCA). However, the Su-57 remains an option, especially given the F-35's unavailability due to India's acquisition of the Russian S-400 air defense system.
The Sukhoi Su-57 is a twin-engine, stealth multirole fighter first developed in 1999 and introduced to the Russian military in 2020. Known for its air superiority and ability to engage surface and maritime targets, the Su-57 boasts stealth features, super-maneuverability, and a large payload capacity. Despite its advanced capabilities, the Su-57 has faced technological and financial hurdles, including issues with structural integrity during early tests.
The Su-57 features a blended wing body fuselage, extensive use of composites, and advanced stealth technologies aimed at reducing radar and infrared signatures. It is equipped with sophisticated avionics, including a modular avionics system and various radar systems for enhanced situational awareness. The aircraft can deploy various countermeasures and is being tested for advanced AI and unmanned teaming technologies.
Russia's production of the Su-57 has been slow, with plans for significant expansion. Initial operational use included deployments in Syria and Ukraine, demonstrating the aircraft's capabilities in combat situations. Future developments include an upgraded Su-57M variant, a potential carrier-based version, and integration with the Okhotnik UCAV for uncrewed operations.
In contrast, China’s Chengdu J-20 ‘Mighty Dragon’ has seen rapid production, with nearly 250 units built. Designed for air superiority and precision strikes, the J-20 features advanced stealth design, powerful radar systems, and high maneuverability. The J-20’s production and deployment have outpaced the Su-57, reflecting China's growing military capabilities.
India, once a partner in the FGFA project, remains cautious about fully committing to the Su-57. Given the challenges and delays in developing the AMCA, India might reconsider the Su-57 or explore other options like the Su-75 Checkmate. However, with China's expanding J-20 fleet and potential threats from neighboring countries, India must act swiftly to ensure its air force remains competitive.
The Su-57 and J-20 will likely compete for market share in regions like Africa, West Asia, and Southeast Asia. Despite their differences, both aircraft offer cost-competitive solutions for countries seeking advanced air combat capabilities. As the global landscape of fifth-generation fighters evolves, India’s decisions will significantly impact its strategic military position.
