The Sukhoi Su-30MKI (NATO reporting name: Flanker-H) is a two-seater, twinjet multirole air superiority fighter developed by Russian aircraft manufacturer Sukhoi and built under licence by India's Hindustan Aeronautics Limited (HAL) for the Indian Air Force (IAF). A variant of the Sukhoi Su-30, it is a heavy, all-weather, long-range fighter.
Development of the variant started after India signed a deal with Russia in 2000 to manufacture 140 Su-30 fighter aircraft. The first Russian-made Su-30MKI variant was accepted into the Indian Air Force in 2002, while the first Su-30MKI assembled in India entered service with the IAF in November 2004. The IAF has nearly 260 Su-30MKIs in inventory . The Su-30MKI was expected to form the backbone of the IAF's fighter fleet beyond 2020.
The aircraft is tailor-made for Indian specifications and integrates Indian systems and avionics as well as French and Israeli sub-systems. It has abilities similar to the Sukhoi Su-35 with which it shares many features and components.
Development
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)."Su-30МК – Historical background." Sukhoi Company (JSC). Retrieved 30 September 2012."Orders For Su-30MKI Fighters Top $5 Billions." RTAF, 4 December 2008. Retrieved 16 December 2010. The Su-30MKI is derived from the Sukhoi Su-27 and combines technology from the Su-37 demonstrator and Su-30 program, being more advanced than the baseline Su-30. Russia's Defence Ministry was impressed with the type's performance envelope and ordered 30 Su-30SMs and a localised Su-30MKI, for the Russian Air Force. 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.Malhotra, Jyoti. "Delhi tightrope on Israel red carpet." The Indian Express, 20 August 2003. Retrieved 16 December 2010."PIB Press Release." NIC. Retrieved 16 December 2010. The Su-30MK variants were equipped with a N001 ‘Myech’ radar and armed with the R-27 and later the R-77 missile systems.
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-30Ks were returned to Russia in 2007 for a similar number of Su-30MKIs. Following refurbishment in Belarus, 12 of them were sold to Angola in 2017 and 2019 and the remaining six to Ethiopia in 2024, despite requests to maintain the platforms as testbed aircraft.
In October 2000, a memorandum of understanding (MoU) was signed for Indian licence 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 licence at HAL's Indian facilities in 2004. The first Nashik-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."Day after crash, IAF grounds Sukhoi fleet for checks." The Times of India, 2 December 2009. 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."Sukhoi Su-30 MKI (Flanker)." Bharat-rakshak. Retrieved 16 December 2010. 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-knockdown 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."House testimony." Indian Government, 7 August 2009. 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."Samtel to produce Avionics display systems for HAL's star programmes." Indiaaviation.aero, 15 July 2008. Retrieved 16 December 2010. 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.Joseph, Josy. "Rs 15,000 crore Sukhoi deal cleared." The Times of India, 26 June 2010."Sukhoi jets." Mid-day.com. Retrieved 30 September 2012.
By August 2010, the cost increased to $4.3 billion or $102 million each.Sharma, Suman. "Aircraft deals with friend Russia costing dear." Dnaindia.com, 17 August 2010. Retrieved 16 December 2010. This increased unit cost compared to the previous unit cost of $40 million in 2007, led to rumours that the 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 Ministry of Defence for setting up two dedicated squadrons of fighters consisting of 40 aircraft capable of delivering nuclear weapons."Strategic Command to acquire 40 nuclear capable fighters." Hindustan Times, 12 September 2010. Retrieved 20 December 2010.
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".Radyuhin, Vladimir. "HAL: total indigenisation of Sukhoi fighter next year." The Hindu (Chennai, India), 20 August 2009. 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."India to buy 42 combat aircraft from Russia." brahmand.com, 11 October 2012. 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.
As of 2024, the IAF has received a total of 272 units of Su-30MKI, with phased orders of 50 units directly imported followed by orders of 140 units in December 2000, 40 in March 2007 and 42 in December 2012.
Additional purchase On June 2018, India reportedly decided not to order any further Su-30s since it considered the cost of maintenance very high compared to Western aircraft. However, on June 2020, India reversed its decision and ordered 12 more Su-30MKIs along with 21 MiG-29s. The Su-30MKI order was to compensate for losses due to crashes and 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, having been built for an order that was previously cancelled, 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 Russia's ability to deliver parts to Hindustan Aeronautics and issues related to payment transfers. On 15 September 2023, the Indian government preliminarily approved to obtain 12 Su-30MKIs for the air force with more than 60% indigenous content to replace jets that had 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 restart operations of its Nashik plant near the Nashik Airport to execute the order. The same facility had previously produced 272 units of the jet earlier. A dozen of "new material kits" to fulfil the 12 Su-30MKI contract requirements had arrived from Russia in April 2026. As per August 2026 reports, the aircraft will be delivered between FY2027–28 and 2029.
