In a significant development that could reshape the contours of India's defence capabilities, Russia has offered to make its fifth-generation stealth fighter jet, the Sukhoi Su-57, in India for the Indian Air Force. This innovative proposal, announced on June 4, 2025, represents the most comprehensive technology transfer deal ever offered to India in the defence sector.
The Su-57E is the export variant of the Su-57. It consists of advanced radar systems, hides weapons inside internal bays instead of outside, and has a slanted shape that deflects radar waves. Its curved air intakes also block radar from seeing the engine blades. It has the capability for sustained supersonic flight without afterburners. It is designed with stealth features to make it harder for enemies to detect and is a comprehensive suite of weaponry optimised for air superiority and precision strike missions. Together, these features reduce the jet's radar and heat signatures, making it much harder to spot or track. It is considered a technologically mature and combat-proven platform that could potentially be integrated into the Indian Air Force with relative ease.

Russia's Strategic Proposal
Russia's offer, which was presented by Rosoboronexport and United Aircraft Corporation (UAC) at Aero India 2025, extends beyond a conventional supply and demand arrangement. It proposes joint production of the Su-57E at Hindustan Aeronautics Limited's (HAL) Nashik facility, where the Su-30MKI is already assembled. The Russian proposal includes a transfer of technology, which allows India to customise the aircraft with indigenous systems like AESA radars, avionics and weaponry. This flexibility in the proposal aligns with the push for self-reliance with the 'Make in India' initiative, serving as a catalyst for transforming the country into a global manufacturing hub for domestic defence production and advancing the vision of Atmanirbhar Bharat. With HAL's established infrastructure, India could adopt the Su-57E technology rapidly, potentially delivering aircraft within a shorter timeline and ensuring that production and maintenance will not be affected by Western sanctions on Russia.
Russia's offer for India is three-dimensional—it will commence the local production of Su-57E, upgrade the Su-30MKI fighter jets with advanced technology, and will back and assist India towards its own fifth-generation Advanced Medium Combat Aircraft (AMCA) program.
Russia has also offered to give India access to the Su-57E's software system, which is considered a game changer, as such technological access is rarely given. Countries like the US or France do not allow such access during the sale of their own fighter jets. The access to source codes reflects Russia's openness with the offer and gives India more control and directly responds to a major concern India had during the Rafale fighter jet deal with France.
Despite India's repeated efforts through diplomatic channels, France refused to share the Rafale's source code. This refusal made it very difficult for India to fully customise the Rafale jets to its changing defence needs. It has also caused issues in integrating Indian-made weapons like the Astra missile and Smart Anti-Airfield Weapon (SAAW) onto the Rafale, despite ongoing cooperation between the two countries in other areas. If accepted, Russia's offer could give India a major edge in future air combat and could potentially mark a turning point in the country's efforts to modernise its air force.
Navigating the China-Pakistan Security Challenge
With Pakistan's deepening defence collaboration with its iron brother and China's latest foray into fifth-generation stealth fighter technology, India needs a strategic defence procurement to address the evolving air power landscape in the region. Amidst the persistent geopolitical tensions between India and China, the reports of Pakistan potentially introducing two squadrons of Chinese J-35 fighter jets into the Pakistan Air Force soon can drastically alter the aerial military balance in South Asia.

The J-35, also known as the FC-31 Gyrfalcon, positions China as a competitor to advanced aircraft like the American F-35. This acquisition of J-35 will augment Pakistan's air combat strength, potentially challenging India's existing air superiority. To counter this growing defence capability, the procurement and manufacturing of Russia's Su-57E is essential. Also, India's own fifth-generation AMCA, developed by the Aeronautical Development Agency and Defence Research and Development Organisation, remains in the early stages of development and is not expected to enter operational service before the mid-2030s. This projected timeline may create a tactical airpower gap over the next five years, and the Russian Su-57E could potentially bridge the gap.
Challenges and Obstacles Ahead
While the offer looks promising, it faces significant obstacles. The United States's Countering America's Adversaries Through Sanctions Act (CAATSA) poses a possibility of sanctions. As earlier seen with India and Russia's S-400 deal, which encountered challenges like facing delays due to payment mechanisms amidst Western sanctions on Russia. With the absence of a robust payment mechanism, similar payment difficulties exist to handle a multi-billion-dollar Su-57 deal. Although the anticipated thaw in US-Russia relations under President Donald Trump may ease pressure of CAASTA sanctions, significant uncertainties still persist, as any major defence transaction with Russia carries the risk of sanctions.

Also, Russia's proposal to India comes at a time when the United States is reportedly preparing to extend a proposal for the sale of its own fifth-generation fighter, the F-35A. Washington sees this deal as a strategic opportunity to bolster India's air power capability in response to China's growing belligerence in the Indo-Pacific. However, for New Delhi, this marks a crucial decision—whether to deepen its decades-long defence partnership with Russia or to expand its security partnership with the US, which is seen as a key to countering China's aggression and its strengthening ties with Pakistan.
The proposal represents a strategic opportunity for India to gain deeper technological autonomy and greater freedom in shaping its defence posture. The Su-57 deal could emerge as one of the most significant defence collaborations between India and Russia in the 21st century—potentially propelling India into the ranks of nations with the capability to produce fifth-generation fighters on their own ground.

HAL 1st Indian firm to bag full rocket tech

BENGALURU: Defence PSU Hindustan Aeronautics Ltd has become the first Indian firm to fully acquire technology of a launch vehicle. HAL secured the transfer of technology (ToT) for 's Small Satellite Launch Vehicle (SSLV) at a cost of Rs 511 crore. Tired of too many ads? go ad free now Indian National Space Promotion and Authorisation Centre (IN-SPACe) announced Friday that this first-of-its-kind complete ToT marked a significant milestone. Unlike the manufacturing contract of PSLV - shared between HAL and L&T - the SSLV has been fully offered to HAL. The company will own the rocket, build it, market it, and launch it independently. The selection process involved two stages. Out of nine applicants, six were shortlisted in the first round. A committee led by former principal scientific adviser to govt of India, Prof Vijaya Raghavan, and co-headed by former Isro director Suresh, then evaluated the techno-commercial bids of three firms. All were technically qualified but HAL emerged as the highest bidder at Rs 511 crore, IN-SPACe chairman Pawan Goenka said. While HAL submitted an independent bid, the other two finalists were consortia - one led by Bengaluru-based Alpha Design and the other by Bharat Dynamics Ltd from Hyderabad. "Payment will be done in phases. ToT will take two years. HAL will make at least two SSLV prototypes with complete help and hand-holding by Isro and after two years, they will be on their own. The initial ToT agreement will be for the first two years and then another contract will be signed between HAL and Isro," Goenka said. After the initial two years, HAL will function independently and can even modify the rocket design or choose new partners. Tired of too many ads? go ad free now A formal contract involving NewSpace India Ltd (Nsil), HAL, Isro and IN-SPACe will be signed soon. Nsil will manage the commercial aspects while IN-SPACe, in collaboration with Isro centres, will oversee the technology transfer. Barenya Senapati, HAL's director of finance, said the win aligned with HAL's broader goal of significantly expanding its space portfolio. He assured the new programme would not affect HAL's other operations. Regarding liability for rocket launches, Goenka noted that, under international norms, the state bore primary responsibility. "It is up to govt to decide how much of the liability will remain with the state and how much will be transferred to HAL. The company will comply with applicable laws once the contract is finalised," he said.

HAL wins ₹511-crore deal to build, own and commercialise SSLV launches

The Hindustan Aeronautics Limited has bagged a Transfer of Technology (ToT) deal, valued at ₹511 crore, from the Indian Space Research Organisation, to build and operate Small Satellite Launch Vehicles (SSLVs). The SSLV is a three-stage vehicle to launch satellites that weigh less than 500 kg into the Lower Earth Orbit (LEO). The Indian National Space Promotion and Authorisation Centre (IN-SPACe) on Friday announced the HAL as the winning bidder among three shortlisted bidders. The deal will enable commercialisation of SSLV launches. Other contenders Apart from the HAL, which had applied independently, two other technically qualified bidders were shortlisted: Alpha Design Technologies Ltd., Bengaluru, leading a consortium with Agnikul Cosmos and Walchand Industries Ltd.; and Bharat Dynamics Ltd., Hyderabad, leading a consortium with Skyroot Aerospace, Keltron and Bharat Heavy Electricals Limited (BHEL). Among the three, HAL emerged as the highest bidder. Pawan Goenka, Chairman, IN-SPACe, announced the winner. 'The HAL will be giving ₹511 crore. It is a phased payment that will be done with some amount at the time of signing the contract and the remaining coming over a period of two years. The ToT phase will take two years and during these two years, the HAL will make at least two SSLV rockets with complete help and handholding from the ISRO and after two years, they will be on their own. So during the two years, they will draw all the technology and take it from there,' Dr. Goenka said. Rigorous evaluation IN-SPACe said the bidding process involved a rigorous eligibility and evaluation framework. 'A thorough evaluation process was followed, with various technology and financial readiness levels under review. The process, which continued for several months, culminated in the financial bid evaluation, where the HAL emerged as the highest bidder to acquire and operationalise SSLV technology,' the IN-SPACe said. The ToT Agreement will be signed among HAL, NewSpace India Limited (NSIL), ISRO, and IN-SPACe. The agreement encompasses extensive training and handholding of HAL personnel by ISRO teams, both at ISRO and HAL facilities, for the realisation and launch of two SSLVs in the next two years. 'The launch vehicle system, being multidisciplinary in nature, would require the winning entity, HAL, to undergo rigorous handholding and training under ISRO at both ISRO's and the entity's facilities. This is aimed at realising the projected launch of two SSLVs from an Indian launch port,' Rajeev Jyoti, Director, Technical Directorate, IN-SPACe, said. Barenya Senapati, Director (Finance), HAL said that the PSU intends to build six to 12 SSLVs per year during the production phase and that it may ramp up based on demand and requirement. Space launch liability To a question on who will take the liability of a privately manufactured SSLV, Dr. Goenka said the state (Government of India) has the responsibility. 'It is an international rule and not something India or the HAL or IN-SPACe can decide. Now, it is up to the Indian government to decide how much of that liability they keep on themselves and how much they pass on to the owner and launcher of the vehicle. As per the contract we will have, the HAL will follow whatever is the law of the land.' 'We will come out with a decision on how the launch liability will be shared between the owner of the rocket and the Government of India,' he added.
