, 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 jets. The first Russian-made Su-30MKI variant was accepted into the Indian Air Force in 2002, while the first indigenously assembled Su-30MKI entered service with the IAF in 2004. In 2007, the IAF ordered 40 additional MKIs. As of January 2011, the IAF has 142 MKIs under active service with plans to have an operational fleet of 280 MKIs by 2015. The Su-30MKI is expected to form the backbone of the Indian Air Force's fighter fleet to 2020 and beyond.

The aircraft is tailor-made for Indian specifications and integrates Indian systems and avionics as well as French and Israeli subsystems. It has abilities similar to the Sukhoi Su-35

 which includes display, navigation, targeting and electronic warfare systems. Some avionics suites used in the aircraft were also sourced from France and South Africa.

After 2 years of evaluation and negotiations, India signed a US$1.462 billion deal with the Sukhoi Corporation on 30 November 1996 for the delivery of 50 Su-30MKI aircraft in five batches. The first batch were 8 Su-30MKs, the basic version of Su-30. The second batch were to be 10 Su-30Ks with French and Israeli avionics. The third batch were to be 10 Su-30MKIs featuring canard foreplanes. The fourth batch of 12 Su 30MKIs and final batch of 10 Su-30MKIs aircraft all were to have the AL-31FP turbofans. These 50 aircraft were made by Sukhoi in Russia.

In October 2000, a MoU (Memorandum of Understanding) was signed confirming the license production of 140+ Su-30MKIs in India and in December 2000, the deal was sealed at Russia's Irkutsk aircraft plant, with full technology transfer. The first Su-30MKIs from Nasik were to be delivered from 2004, with the staged production until 2017–18. However in November 2002, the delivery schedule was expedited with production to be completed in ten years – by 2014-15 – by increasing the annual rate of production from 10 to 14 aircraft annually. 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 Divisions in Lucknow and Hyderabad. Final integration of the aircraft and its test flight are to be carried out at HAL's Nasik Division. The MKI production was planned to be done in four phases: Phase I, II, III and IV respectively.

In 2007, another order of 40 Su-30MKIs was placed. In 2009, the planned fleet strength of Su-30-MKIs was reported to be 230 aircraft. In 2008, Samtel HAL Display Systems (SHDS), a joint venture between Samtel Display Systems and HAL

, 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, sources in the Indian Defense Ministry announced that a contract for 42 more Su-30MKI was in the final phases. 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. Of these 42 aircraft being procured, two replace the aircraft that crashed in 2009. By August 2010, the cost increased to $4.3 billion or $102 million each, comparable in cost to the Lockheed Martin F-35 Lightning II, but lacking in features such as stealth. 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 40 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 also expects that indigenisation of the Su-30MKI program will 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 January 2011, 142 Su-30MKIs had been delivered to the Indian Air Force.

). It has direction finding capability and is known to have a programmable threat library. The RWR is derived from work done on an earlier system for India's MiG-23BNs known as the Tranquil, which is now superseded by the more advanced Tarang series. Elta EL/M-8222 a self-protection jammer developed by Israel Aircraft Industries is the MKI's standard EW pod, which the Israeli Air Force uses on its F-15s. The ELTA El/M-8222 Self Protection Pod is a power-managed jammer, air-cooled system with an ESM receiver integrated into the pod. The pod contains an antenna on the forward and aft ends, which receive the hostile RF signal and after processing deliver the appropriate response.

 (27,550 lbf) of full afterburning thrust. These by-pass, thrust-vectoring engines push the aircraft up to mach two in horizontal flight (about 2450 km/h at ground-level) and give a rate of climb of 230 m/s. The mean time between overhaul for the AL-31FP is given at 1,000 hours with a full-life span of 3,000 hours. The titanium nozzle has a mean time between overhaul of 500 hours. Al-31FP builds on the Al-37FU with the capability to vector in two planes. The Thrust Vectoring

Thrust vectoring, also thrust vector control or TVC, is the ability of an aircraft, rocket or other vehicle to manipulate the direction of the thrust from its engine or motor in order to control the attitude or angular velocity of the vehicle....

 nozzles of the MKI are mounted 32 degrees outward to longitudinal engine axis (i.e. in the horizontal plane) and can be deflected ±15 degrees in the vertical plane. This produces a cork-screw effect, thus enhancing the turn capability of the aircraft. There is no strain-gauge engine control stick to change the engine thrust in the cockpit, rather just a conventional engine throttle control lever. The pilot controls the aircraft with help of a standard control stick. On the pilot's right there is a switch which is turned on for performing difficult maneuvers. After the switch-over, the computer determines the level of use of aerodynamic surfaces and swiveling nozzles and their required deflection angles.

Fuel system

The Su-30MKI has a range of 3,000 km with internal fuel which ensures a 3.75 hour combat mission. Also, it has an in-flight refueling (IFR) probe that retracts beside the cockpit during normal operation. The air refueling system increases the flight duration up to 10 hours with a range of 8,000 km at a cruise height of 11 to 13 km. Su-30 MKIs can also use the Cobham 754 buddy refueling pods.

. This was the first time that the two jets had taken part in such a exercise. The IAF did not allow their pilots to use the radar of the MKIs during the exercise so as to protect the highly classified N011M Bars. Also in the exercise were RAF Tornado F3s and a Hawk. RAF Tornado pilots were candid in their admission of the Su-30MKI's superior manoeuvring in the air, but the IAF pilots were also impressed by the Typhoon's agility. The summary of the Indra-Dhanush is often mis-quoted by leaving the word "Tornado" out of the statement, to make it appear that the Typhoon was less manoeuvrable than the Su-30MKI. The RAF however, were adamant that the Typhoon and Sukhoi did not actually go head to head in mock combat on that particular exercise.

In October 2008, a video surfaced on the internet which featured a USAF colonel, Corkey Fornoff, criticizing Su-30MKI's high friendly kill rate, serviceability issues, and relatively poor performance against the F-15C during the Red Flag exercise. Several of his claims were later rebutted by the Indian side and the USAF also distanced itself from his remarks.

In June 2010, India and France began the fourth round of their joint air exercises, "Garuda", at the Istres Air Base in France. During Garuda, the IAF and the French Air Force

 system". The Sukhoi fleet had then been grounded for around three weeks. However it was found that this crash at Rajmathai village, around 170 km from Jaisalmer, in April was because of the position of the various critical switches of the aircraft. The switches were behind the pilots and they would have to turn them on and off without looking back. At one point, a wrong switch was turned on, leading to the crash on 30 April. Wing Commander PS Nara was killed in the mishap, while Wing Commander SV Munje was injured. After investigators identified the problem, a couple of difficult switches were sealed off.

Another Su-30MKI aircraft crashed on 30 November 2009 in Jathegaon, about 40 km from Jaisalmer. The pilots ejected after they saw fire alarm buttons glowing red. Both the pilots are unharmed. This is second such crash of this fighter. The Sukhoi mishaps have come as a setback to the 12 year safety record IAF had achieved with the aircraft which was inducted into the force in 1997. As a result the entire fleet of Su-30MKIs was grounded while the cause of the problem was investigated. It was attributed to accidental ingestion of a foreign material in the engine intake.
