India declines upgrade for Su-30MKI fighter jets VIDEO

Russia’s Rosoboronexport recently proposed an upgrade of 80 of India’s Su-30MKI fighter jets to the advanced AL-41F-1S engine, but Indian officials have decided to maintain the current AL-31FP engine.

The AL-31FP, an afterburner turbojet developed by Russian company Saturn specifically for the Su-30MKI, has proven reliable and effective. It delivers a maximum thrust of 12,500 kilogram-force (kgf) in afterburner mode and is designed to operate optimally at altitudes of up to 20,000 metres, Caliber.Az reports, citing foreign media. 

In contrast, the AL-41F-1S engine, designed for the Su-35, offers enhanced performance with a maximum thrust of 14,500 kgf and improved fuel efficiency. 

Despite these advantages, India prefers to stick with the AL-31FP due to established logistics, maintenance infrastructure, and personnel familiarity. Switching to the AL-41F-1S would necessitate significant investments in upgrades and training, which are not financially viable under current budget constraints.

The AL-31FP has consistently met the operational needs of the Indian Air Force (IAF), providing sufficient power and efficiency for various missions. Furthermore, India is set to manufacture 240 AL-31FP engines for its Su-30MKI fleet over the next eight years, valued at $3.13 billion. This initiative, led by Hindustan Aeronautics Limited (HAL), emphasises India’s push for self-reliance in defence production while strengthening its strategic relationship with Russia.

 With approximately 260 Su-30MKI fighters, the IAF relies heavily on these jets, which are lauded for their versatility in both air superiority and ground attack roles. Since their introduction, Su-30MKIs have participated in numerous exercises and operations, including combat air patrols and precision strike missions with the BrahMos cruise missile. As India continues to bolster its defence capabilities, the decision to stick with the AL-31FP engine reflects a preference for stability and reliability in a rapidly changing geopolitical landscape.
