Origins and acquisition The Su-30MKI was designed by Russia's Sukhoi Corporation beginning in 1995 and built under licence by India's
Hindustan Aeronautics Limited (HAL). The Su-30MKI is derived from the
Sukhoi Su-27 and has a fusion of technology from the
Su-37 demonstrator and Su-30 program, being more advanced than the baseline
Su-30. It features state-of-the-art avionics developed by Russia, India and Israel for display, navigation, targeting and electronic warfare; France and South Africa provided other avionics. After two years of evaluation and negotiations, on 30 November 1996, India signed a US$1.462 billion deal with Sukhoi for 50 Russian-produced Su-30MKIs in five batches. The first batch was eight Su-30Ks, the basic export version of Su-30 (designated Su-30MKI-I by India). The second batch of 10 was also Su-30Ks, but equipped with French and Israeli avionics (designated Su-30MKI-I by India). The third batch were to be 10 Su-30MKIs featuring
canard foreplanes. The fourth batch of 12 Su-30MKIs and fifth batch of 10 Su-30MKIs were to have the AL-31FP turbofans. The Su-30Ks were upgraded to Su-30MKI configuration by HAL later on. The 18 Su-30K's were returned to Russia in 2007 for a similar number of Su-30MKI's. Following refurbhisment in
Belarus, 12 of them were sold to
Angola in 2017 and 2019 and the remaining six to
Ethiophia in 2024, despite requests to maintain the platforms as testbed aircraft. In October 2000, a
memorandum of understanding (MoU) was signed for Indian license production of 140 Su-30MKIs; in December 2000, a deal was sealed at Russia's Irkutsk aircraft plant for full technology transfer. The Indian Air Force (IAF) has ordered 272 aircraft, of which 50 were to be delivered by Russia in 2002-2004 and 2007. The rest of the 222 planes are to be produced under license at HAL's Indian facilities in 2004. The first Nasik-built Su-30MKIs were to be delivered by 2004, with staggered production until 2017–18. In November 2002, the delivery schedule was expedited with production to be completed by 2015. An estimated 920 AL-31FP turbofans are to be manufactured at HAL's Koraput Division, while the mainframe and other accessories are to be manufactured at HAL's Lucknow and Hyderabad divisions. Final integration and test flights of the aircraft are carried out at HAL's Nasik Division. Four manufacturing phases were outlined with progressively increasing Indian content: Phase I, II, III and IV. In Phase I, HAL manufactured the Su-30MKIs from knocked-down kits, transitioning to semi knocked-down kits in Phase II and III; in Phase IV, HAL produced aircraft from scratch from 2013 onwards. In 2007, another order of 40 Su-30MKIs was placed. In 2009, the planned fleet strength was to be 230 aircraft. In 2008, Samtel HAL Display Systems (SHDS), a joint venture between Samtel Display Systems and HAL, won a contract to develop and manufacture
multi-function avionics displays for the MKI. A
helmet mounted display, Topsight-I, based on technology from Thales and developed by SHDS will be integrated on the Su-30MKI in the next upgrade. In March 2010, it was reported that India and Russia were discussing a contract for 42 more Su-30MKIs. In June 2010, it was reported that the
Cabinet Committee on Security had cleared the deal and that the 42 aircraft would be in service by 2018. By August 2010, the cost increased to $4.3 billion or $102 million each. This increased unit cost compared to the previous unit cost of $40 million in 2007, has led to the rumours that these latest order of 42 Su-30MKIs are for the
Strategic Forces Command (SFC) and these aircraft will be optimised and hardwired for nuclear weapons delivery. The SFC had previously submitted a proposal to the Indian Defence Ministry for setting up two dedicated squadrons of fighters consisting of 40 aircraft capable of delivering nuclear weapons. HAL expected that indigenisation of the Su-30MKI programme would be completed by 2010; V. Balakrishnan, general manager of the Aircraft Manufacturing Division stated that "HAL will achieve 100 per cent indigenisation of the Sukhoi aircraft – from the production of raw materials to the final plane assembly". As of 2017, HAL manufactures more than 80% of the aircraft. On 11 October 2012, the Indian Government confirmed plans to buy another 42 Su-30MKI aircraft. On 24 December 2012, India ordered assembly kits for 42 Su-30MKIs by signing a deal during President Putin's visit to India. This increases India's order total to 272 Su-30MKIs.
Additional purchase Initially, it was reported in June 2018 that India has reportedly decided not to order any further Su-30s as they feel its cost of maintenance is very high compared to Western aircraft. However in June 2020, India decided to order 12 more Su-30MKIs along with 21
MiG-29s. The Su-30MKI order is to compensate for losses due to crashes to maintain the sanctioned strength of 272 Su-30MKIs. The MiG-29 order was placed to form a fourth MiG-29 squadron to bolster depleted IAF strength. The MiGs were ordered despite being an older platform since they were deliverable within a 2-3-year timeframe, because they were built for an order that was previously canceled and since they were very reasonably priced compared to newer aircraft. On 18 March 2022, it was reported that India would order an additional 12 Su-30MKIs. In May 2022, the Indian government suspended the Su-30MKI order due to concerns over Moscow's ability to deliver parts to Hindustan Aeronautics and issues related to payment transfers. On 15 September 2023, the Indian government preliminarily approved to procure 12 Su-30MKIs for the air force with more than 60% indigenous content to replace jets that have crashed. The additional Su30MKIs will be incorporated with the Super Sukhoi upgrades. As of November 2024, the order is expected to be finalised by the end of
FY2024-25. On 12 December 2024, the
Cabinet Committee on Security cleared the procurement at a cost of . The contract was signed on the same day. These aircraft will feature an indigenous content of around 62.6%. HAL will be restarting operations of its
Nashik plant near
Nashik Airport for the new potential orders which was previously used for producing 272 units of the jet earlier. The 12 jets are to be delivered at a short span of time. A dozen of "new material kits" to fulfil the 12 Su-30MKI contract requirements had arrived from Russia by April 2026. The jet deliveries will begin from the end of 2026. HAL could also deliver 13 jets according to sources.
Upgrades In 2004, India signed a deal with Russia to domestically produce the
Novator K-100 missile, designed to shoot down
airborne early warning and control (AEW&C) and
C4ISTAR aircraft, for the Su-30MKI, however the project did not proceed. In May 2010,
India Today reported that Russia had won a contract to upgrade 40 Su-30MKIs with new
radars, onboard computers,
electronic warfare systems and the ability to carry the
BrahMos cruise missile. The first two prototypes with the "Super-30" upgrade would be delivered to the IAF in 2012, after which the upgrades would be performed on the last batch of 40 production aircraft. The Brahmos missile integrated on the Su-30MKI will provide the capability to attack ground targets from stand-off ranges of around 300 km. On 25 June 2016, HAL conducted the first test flight of a Su-30MKI fitted with a BrahMos-A missile from
Nashik, India. The first air launch of BrahMos from a Su-30MKI was successfully carried out on 22 November 2017. The Indian Defence Ministry proposed several upgrades for the Su-30MKI to the Indian Parliament, including the fitting of Russian
Phazotron Zhuk-AE
Active electronically scanned array AESA radars starting in 2012. During MMRCA trials the Zhuk-AE AESA radar demonstrated significant capabilities, including ground-mapping modes and the ability to detect and track aerial targets. At the 2011 MAKS air-show,
Irkut chairman Alexy Fedorov offered an upgrade package with an improved radar, and reduced radar signature to the Indian fleet to make them "Super Sukhois". But the plan for equipping the jets with Russian AESA radar was dropped in favor of phase wise upgradation of the jets with Indian avionics like by equipping the jets with an enlarged variant of Indian made
Uttam AESA radar that was developed for the
HAL LCA. India also started to replace the Russian made
fly-by-wire system with an Indian-made Flight Control system and even adopted a new digital RWR (
Radar Warning Receiver) to replace the outdated manual Radar Warning Receiver previously used. In 2011, India issued a request for information to MBDA for the integration of the
Brimstone ground attack missile and the long-range
Meteor air-to-air missile. In 2012, upgrades of the earlier 80 Su-30MKIs involved equipping them with stand-off missiles with a range of 300 km; a
request for information (RFI) was issued for such weapons. In August 2017, the Indian government cleared a proposal of to equip the planes with new reconnaissance pods. India is currently increasing the Su-30MKI's
Beyond Visual Range (BVR) engagement capability by arming its entire fleet with the indigenous
Astra missile having a range of 110 km and the Israeli
Derby after it was found that the Russian
R-77 active-radar homing BVR missile has inadequate performance. In September 2019, the Astra missile was in multiple user-trials by Indian Air Force to validate its lethality for the Su-30MKI. Although not initially designed to carry nuclear or strategic weapons, India has considered integrating an air-launched version of the nuclear-capable
Nirbhay cruise missile.
Super Sukhoi project In 2024, the Super Sukhoi project — a programme to upgrade IAF's Su-30MKI, considered the backbone of its fleet — was first announced. The upgrade included the introduction of
AESA radars, long-range weapons and
electronic warfare suite (EWS) to the fleet in order to extend its service life by 30 years. Additionally, the Su-30MKI will have
Suppression of Enemy Air Defenses (SEAD) capabilities along with offensives against ground targets in contested airspace. The upgrade is to be carried out by
Hindustan Aeronautics Limited (HAL) with the support of
Defence Research and Development Organisation (DRDO) and several private companies. Overall, 51 systems are to be upgraded including 30 by HAL, 13 by DRDO and 8 by private sector companies. The Indian indigenous content shall be increased to 78%. The upgrade is to allow the fighter to remain in service beyond 2055. Under this upgrade, many older Russian subsystems will be replaced by more modern Indian subsystems. Initially, around 90 aircraft will be upgraded to these standards. According to a report, "The project is divided into two phases, focusing initially on installing new avionics and radars, followed by enhancements to the flight control systems." "The upgrade will see significant private sector participation, with HAL as the lead integrator," CMD of HAL CB Ananthakrishnan said. As of late October 2025, the ministry was examining the proposal to fast-track its clearance from the
Cabinet Committee on Security (CCS). The CCS approval will be followed by the design and development phase. HAL has set a timeline to deliver the
initial operational clearance (IOC) and final operational clearance (FOC) version within the fifth and seventh year of CCS nod, respectively. The upgraded aircraft will receive a redesigned cockpit along with new avionics, radars and IR sensors, a new electronic warfare suite including jammer pods. The CCS clearance was expected soon as of 27 November 2025. Russia is likely to have a small role in the project. However, the approval is yet to be accorded as of 25 February 2026. It was reported that the Indian Air Force is now considering a parallel upgrade programme from Russia for a similar or larger quantity of aircraft. This upgrade, in line with the earlier
MiG-21Bison upgrade, will "offset the long execution timeline" of the Super Sukhoi project since the project's
final operational clearance (FOC) timeline might not be realised as expected. The parallel project will focus on the electronic warfare suite, radar and the Russian-offered
AL-41 engine. If the project is taken up after inter-government talks, the proposal would be sent to the Defence Acquisition Council (DAC) for Acceptance of Necessity (AoN). The AoN marks the first formal stage of a programme. Meanwhile, DRDO is undertaking design work for the Super Sukhoi project from its internal budget. However, a substantial financial support is required for full-scale development and integration which could be realised only after CCS clearance and budget allocation. On 3 December 2024, the Defence Acquisition Council (DAC) cleared the procurement of Electronic Warfare Suite (EWS) compromising of External Airborne
Self Protection Jammer pods, Dhruti Next Generation
Radar Warning Receiver, Dual Color
Missile Approach Warning System and associated equipment. : On 15 November 2025, the Ministry of Defence released a
Request for Information (RFI) to procure 100 sets of Aircraft Self Protection Jammers (ASPJ) complemented by associated equipment for the Su-30MKI aircraft. The last date for a vendor to respond to the RFI is 22 December. The deliveries are to be completed within a timeline of 36 months. The pods must be capable of jamming and
spoofing enemy airborne and ground radars. ;Long-range weapons : The jets will also be modified to fire
BrahMos-ER missiles. Other missiles which are to be integrated on these jets include
Rudram-II,
Astra series and
R-37M missiles. As per reports on 1 March 2026, India’s long-range precision strike capability is set for a significant expansion as the air-launched variant of the Long Range Land Attack Cruise Missile (LR-LACM) edges closer to operational testing. Developed by Aeronautical Development Establishment (ADE), the LR-LACM is now being prepared for integration with the Indian Air Force’s frontline strike fighter, the Sukhoi Su-30MKI. ;New engines and others : In August 2024, a report suggested that the Ministry of Defence (MoD) has prepared to sign a deal with HAL to purchase 230
AL-31FP engines under a deal to replace older engines. A total of 950 engines are required. On 2 September,
Cabinet Committee on Security (CCS) approved the purchase of 240 such engines for . The delivery of the engines will continue from 1 year of signing the contract to 8th year of signing the contract. The engines will be manufactured in HAL's Engine Division
Koraput and will have an indigenous content of 54%. The contract was signed officially on 9 September 2024. The first engine was delivered on 1 October 2024 while all the engines will be delivered within 8 years at a production rate of 30 units per year. ;AI systems :
IIT Bombay has been engaged in the development of
Artificial Intelligence-based engine and asset
maintenance solutions for spares, inventory and combat potential optimisation. This will replace the current electronic maintenance management system. Sukhoi will also be involved in the project for the upgrade of
fly-by-wire system. ==Design==
