We Need To Know About The Su-27 Aircraft First Before We Delve More Into Su-30MKI

The arrival of the long-range Su-27 ( NATO code name Flanker ) gave the USSR a formidable fighter that could escort its bomber force, all the way to the UK. The high-performance aircraft, which also had the capability of intercepting aircraft over long distances, came as a shock to NATO planners when it was deployed in the mid-1980s. About 20% larger than the F-15 Eagle, the Su-27 is one of the biggest and most imposing fighters of all time.

Development work began in 1969 under Pavel Sukhoi himself and the prototype first flew in 1977, but early models displayed serious instability problems and it was considerably redesigned. Nevertheless, the Su-27 in service today is considered by many to be the pinnacle of Russian fighter design and the masterpiece of the Sukhoi Bureau.

The fast-climbing and superbly manoeuvrable fly-by-wire Flanker can carry up to 12 air-to-air missiles, including the 112km BVR missile. That amount of missiles gives the Flanker “combet persistence” – it can keep on fighting long after other fighters would have had to run for home (  ” about Bingo” ). Hige internal fuel tanks give a very long range ( up to 3000km ) with no need for drag-including external fuel tanks.

The Su-27s Zhuk radar can targets while continuing to scan for others and perhaps most importantly gives the aircraft a look-down/shoot-down capability. Advanced electronics enable the Flanker to detect and destroy an enemy fighter beyond visual range (BVR) at tree-top height, without the need to descend to that level and lose a height advantage. Specially modified versions have set numerous altitude and climb records.

The Su-27 equips air arms in Russia, Ethiopia, Angola, Indonesia, Ukraine, Kazakhstan, Mongolia, Vietnam and Uzbekistan. China also negotiated manufacturing rights to produce its own Su-27s, which began to appear in December 1998.

The Russian Navy’s carrier arm is equipped with the air-defence Su-33 version, with folding wings and tailplane, arrester hook and a different undercarriage suited to carrier operations. More powerful engines, larger wings and canards produce increased lift for carrier take-offs. The Su-33 is believed to have entered service in 1998. The Su-27 spawned a whole family of fighter aircraft, including the Su-33, Su-35 and Su-37, but the Su-27 is likely to be the mainstay of the Russian aviation industry for some years to come.

Let’s Come To The Su-30MKI, The Concept Behind The Development

The development of the Su-30MKI was driven by the vision of creating a world-class fighter aircraft that would meet the specific operational requirements of the Indian Air Force (IAF). The concept behind its development can be summarised as follows

Strategic Partnership: The development of the Su-30MKI was a result of a strategic partnership between India and Russia. This collaboration aimed to transfer technology, enhance indigenous manufacturing capabilities, and strengthen defence ties between the two nations. Although the Su-30MKI was designed by Russia’s Sukhoi Corporation, with its development commencing in 1995, it wasn’t until almost two years of evaluation and negotiations had passed that India and Sukhoi inked a momentous deal on 30 November 1996. Valued at a staggering US$1.462 billion, the agreement involved the acquisition of 50 Russian-produced Su-30MKIs, to be delivered in five distinct batches.

The initial batch consisted of eight Su-30Ks, which represented the basic export version of the Su-30 and were designated as Su-30MKI-I by India. In the subsequent batch of 10 aircraft, still Su-30Ks, French and Israeli avionics were integrated, marking the evolution of the Su-30MKI-I variant. The third batch, comprising 10 Su-30MKIs, boasted the addition of canard foreplanes, further enhancing the aircraft’s capabilities. Lastly, the fourth and fifth batches were set to include 12 and 10 Su-30MKIs, respectively, with the notable incorporation of AL-31FP turbofans.

Adaptation to Indian Requirements: The idea behind the Su-30 aircraft customization was to cater to India’s specific and diverse operational demands. The Indian Air Force (IAF) aimed for a multirole fighter capable of excelling in both air-to-air and air-to-ground missions, while effectively operating in various terrains and seamlessly integrating with advanced weapon systems. To realize this vision, a memorandum of understanding (MoU) was signed in October 2000, paving the way for the Indian license production of 140 Su-30MKIs.

Following that, in December 2000, a deal was sealed at Russia’s Irkutsk aircraft plant, ensuring the full transfer of technology. The Indian Air Force ( IAF ) placed an order for 272 aircraft, with 50 to be delivered by Russia between 2002 and 2004, as well as in 2007. The remaining 222 planes were scheduled for production under license at HAL’s Indian facilities, specifically the Nasik plant, in 2004.

Moreover, it is estimated that around 920 AL-31FP turbofan engines will be manufactured at HAL’s Koraput Division, while the mainframe and other accessories will be produced at HAL’s Lucknow and Hyderabad divisions. The final integration and test flights of the aircraft are carried out at HAL’s Nasik Division. The manufacturing process is divided into four phases, each 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 Phases II and III. In Phase IV, HAL started producing aircraft entirely from scratch, commencing in 2013 onwards.

Notably, a specific order for 42 Su-30MKIs has been assigned to the Strategic Forces Command (SFC), where these aircraft will undergo optimization and be specially equipped for nuclear weapons delivery. Previously, the SFC presented a proposal to the Indian Defence Ministry advocating the establishment of two dedicated fighter squadrons comprising 40 aircraft, all possessing the capability to deploy nuclear weapons.

Indigenous Integration And Upgrades: A key aspect of the concept was the emphasis on indigenous integration and upgrades, aimed at achieving self-reliance and bolstering the aircraft’s combat capabilities. This involved the seamless integration of Indian systems, such as radar, electronic warfare suite, and the BrahMos missile, which further enhanced its operational effectiveness.

With the incorporation of the BrahMos missile into the Su-30MKI, the aircraft gained the capability to engage ground targets from stand-off ranges of approximately 300 km. On 25 June 2016, HAL successfully conducted the first test flight of a Su-30MKI equipped with a BrahMos-A missile in Nashik, India. Subsequently, on 22 November 2017, the first air launch of the BrahMos from a Su-30MKI was carried out with resounding success.

In addition to the BrahMos integration, the Uttam AESA ( Active Electronically Scanned Array ) radar was developed to provide enhanced situational awareness, target detection, and tracking capabilities. This radar system offers improved range, resolution, and target discrimination compared to previous radar systems. It is capable of simultaneously tracking multiple targets and engaging them with precision-guided weapons.

Long-term Strategic Impact: The concept of developing the Su-30MKI aimed to achieve long-term strategic goals. It aimed to strengthen the domestic defence industry, build technical expertise, and create a robust ecosystem for maintenance, repair, and overhaul ( MRO ) facilities in India.
