The Sukhoi/HAL Fifth Generation Fighter Aircraft (FGFA) represented a fifth-generation fighter initiative derived from the Russian Sukhoi Su-57, developed collaboratively by Sukhoi and HAL for deployment by the Indian Air Force. Later renamed the Prospective Multi-Role Fighter (PMF), the program aimed to incorporate 43 advancements beyond the Su-57, encompassing enhanced sensors, integrated networking, and sophisticated combat avionics. The Indian model was designed as a two-seat configuration, featuring a pilot alongside a weapon systems officer.
Although India reportedly exited the FGFA project in 2018, there were indications of potential re-engagement contingent upon the Su-57 achieving full operational status within the Russian Air Force. Contrarily, Yuri Slyusar, General Director of United Aircraft Corporation, asserted that the initiative had not been terminated and that India maintained cooperative ties with Russia. In October 2019, Indian Air Force Chief of Air Staff RKS Bhadauria confirmed that India would not proceed with importing stealth fighters like the Su-57, instead prioritizing indigenous developments such as the HAL AMCA.
Development
Following the successful collaboration on the BrahMos missile system, Russia and India initiated a joint venture in early 2007 to develop a Fifth Generation Fighter Aircraft (FGFA).
On 11 September 2010, both countries reached an agreement on a preliminary design contract, subject to Cabinet approval. Subsequently, in December 2010, Hindustan Aeronautics Ltd (HAL), Rosoboronexport, and Sukhoi signed a memorandum of understanding concerning the fighter’s initial design phase.
While Russia’s version features a single-pilot cockpit, the Indian variant was planned to be modified for extended combat range through redesigned wings and control surfaces. By February 2009, Sukhoi’s General Director Mikhail Pogosyan indicated that India would initially receive the same PAK FA aircraft as Russia, differing primarily in software configurations.
The original blueprint envisaged producing 500 units with options for additional aircraft. The Russian Air Force intended to procure 200 single-seat and 50 twin-seat PAK FAs; meanwhile, the Indian Air Force aimed to acquire 166 single-seat and 48 twin-seat FGFAs. Single-seat fighters were slated for assembly in Russia, whereas HAL was to assemble the two-seater models. HAL negotiated a 25% stake in design and development responsibilities, including critical software components such as mission computers, navigation systems, cockpit displays, countermeasure dispensers, and adaptations tailored to meet IAF specifications.
Sukhoi anticipated a market demand of approximately 1,000 fighters over forty years: allocating 200 units each to Russia and India and selling 600 to other international customers. Russian Trade Minister Viktor Khristenko underscored the importance of joint development and production with India to capitalize on both domestic and third-country markets. In 2013, Natsionalnaya Oborona’s Editor-in-chief highlighted that exports of this co-developed fighter could enhance Russia’s share in global arms sales.
Project changes and delays
In May 2012, India’s Ministry of Defence (MoD) announced a two-year postponement in the FGFA project timeline. Ashok Nayak, then chairman of HAL, explained that the Indian Air Force required between 40 and 45 enhancements over the PAK-FA baseline to satisfy national operational demands; these modifications were formally agreed upon with Russian counterparts.
Both air forces planned combined purchases totaling roughly 250 FGFAs at an estimated unit cost of $100 million each—amounting to $25 billion plus development expenses. By October 2012, India reduced its order from an initial 200 units down to 144 aircraft. Concurrently, India’s initial investment escalated from $5 billion to $6 billion, with total project costs estimated at around $30 billion.
In 2013 disclosures revealed that both countries’ fighters would share identical avionics systems. Alexander Fomin emphasized equal financial contributions from both nations; however, Russia acknowledged significant delays and budget overruns. The contract remained unsigned amid IAF allegations that HAL had relinquished up to half of India's development responsibilities. India provided approximately 15% of research and development efforts but covered half of overall expenses.
On 9 March 2015, reports surfaced about an agreement aiming to shorten aircraft delivery intervals from 92 months down to 36 months upon finalization. India consented to relax strict adherence to a 50:50 work-share ratio to prevent further delays; initial production batches would be manufactured in Russia with subsequent assembly by HAL.
By 2016, Indian enthusiasm diminished as Russia decreased its own procurement plans. On 25 January that year, both governments concurred on continuing FGFA development with reduced investments of $4 billion each—allocating $1 billion in the first year followed by $500 million annually over six years. In September 2016, they finalized detailed agreements outlining joint production work-share arrangements.
In May 2017, a significant agreement was announced to conclude FGFA design efforts and advance co-development milestones; this pact was expected later that year. However, progress stalled due to Russia's unexpected demand for $7 billion funding. Consequently, India formed a committee tasked with reassessing FGFA's necessity given escalating costs and ongoing progress on the HAL AMCA initiative.
Reports indicate that India and Russia are considering upgrading the Su-35 platform with stealth features as a cost-effective alternative to pursuing the FGFA program.
Significant obstacles in the programme
On 2 September 2017, the Indian Air Force identified stringent maintenance demands and elevated expenses as primary factors causing hesitation in advancing the project. India aims to develop its indigenous fifth-generation fighter jet to keep pace with China’s air force, which has already deployed the Chengdu J-20 stealth aircraft.
India formally exited the programme on 20 April 2018. Officials from India voiced dissatisfaction with the FGFA’s development pace after extended negotiations, numerous delays, and complications involving Russian partners. Key issues centered on the Su-57’s performance—especially its stealth capabilities—which form the foundation for FGFA development. Nevertheless, India left open the possibility of reengaging with the project once Russia completes operational deployment of the Su-57 or potentially acquiring the finalized aircraft at a later stage.
On 19 August 2018, Yuri Slyusar, General Director of United Aircraft Corporation, refuted claims that the project had been terminated, affirming that discussions between Russia and India regarding the fifth-generation fighter continued.
Russia proposed on 9 July 2019 that India could rejoin the Su-57 programme. Vladimir Drozhzhin, Deputy Director of Russia’s Federal Service for Military and Technical Cooperation, confirmed Russia’s willingness to entertain this offer. Meanwhile, IAF Air Chief Marshal Birender Singh Dhanoa indicated that although the Su-57 was not presently under consideration for procurement, it might be evaluated following its induction into active Russian service.
Design
The Russian proficiency in titanium airframe construction is complemented by Indian expertise in composite materials, particularly applied to the fuselage. Mikhail Pogosyan, head of United Aircraft Corporation, highlighted India’s contributions in advanced airframe engineering, high-tech software development, and other critical system areas.
By August 2014, United Aircraft Corporation (UAC) had finalized the front-end engineering design for the FGFA in accordance with a 2010 agreement signed with India's HAL.
Distinctions for FGFA
The FGFA was planned to be primarily equipped with Indian-developed armaments such as the Astra, a beyond-visual-range (BVR) missile created by India. Following Russian BVR combat doctrines, it would support an array of missile options to enhance operational flexibility. The fighter was also designed to incorporate third-party systems and would feature a distinct AESA radar system known as N079.
The collaborative Indian-Russian operational fighters were set to include 43 enhancements beyond those present in the prototype aircraft.
Russia consented to the Indian Air Force’s demand for a two-seat variant accommodating both a pilot and a weapons systems officer.
