Hindustan Aeronautics Limited (HAL) has successfully manufactured and delivered the first AL-31FP engine for the Indian Air Force (IAF) Su-30MKI fighter jets. This marks a significant milestone in a new 3.1 billion dollar contract signed on September 9, 2024, which calls for the production of 240 engines over the next eight years. The first engine, built at HAL’s Sukhoi Engine Division plant in Odisha, was officially handed over to the IAF as part of the agreement.
The Indian Ministry of Defence has hailed this achievement as a testament to HAL’s expertise in producing advanced aircraft engines. This success reinforces the company’s commitment to supporting the Indian Air Force’s modernisation efforts with cutting-edge technology. The Sukhoi Engine Division plant, which developed the engine, has integrated modern infrastructure and global-standard technologies to ensure the production of high-quality engines for the Su-30MKI fleet.
To fully meet the needs of the Indian Air Force, a total of 950 new engines will be required to power the Su-30MKI fleet as part of an extensive modernisation program. Upgrading the Su-30MKI fighter jets with new Russian-licensed engines is crucial to extending their operational life until 2055. The modernisation program includes enhanced radars, avionics, integrated drone systems, and long-range weaponry such as the Astra air-to-air missiles with a range of 350 km.
The production of the first license-built engine represents a broader initiative between India and Russia to further enhance the Su-30MKI fleet. Discussions are currently underway to expand the licensed production of these jets by an additional 50 units. This could result in the manufacture of new fighters for both the IAF and potential export markets. These discussions form part of a long-standing military partnership between the two nations, with Russia providing technical kits for licensed assembly in India.
In September 2023, India approved the acquisition of 12 new Su-30MKI fighters, valued at approximately 1.33 billion dollar. These new aircraft will be produced under license at HAL and feature Indian-made avionics and weapons systems.
Further discussions between India and Russia are focused on potentially upgrading the IAF’s Su-30MKI jets to the Su-30SM2 standard, which includes improved engine performance, enhanced airframes, and greater combat capabilities. The upgraded jets would approach the performance level of the Su-35S, Russia’s frontline multi-role fighter. Joint production projects aimed at global markets are also being explored.
The Su-30MKI, designed by Russia specifically for the Indian Air Force, is a twin-seat, multi-role fighter jet that has become a key component of India’s aerial defense. Classified as a medium-heavy fighter, it is built for both air-to-air combat and ground-attack missions. The Su-30MKI measures 21.9 meters in length, with a wingspan of 14.7 meters and a height of 6.4 meters. It has an empty weight of 18,400 kg, with a maximum take-off weight of 38,800 kg.
Equipped with two AL-31FP engines, each generating 122.58 kN of thrust, the Su-30MKI boasts exceptional maneuverability. The engines’ thrust vectoring capabilities allow the aircraft to perform complex aerial maneuvers, making it a formidable asset in dogfights. The fighter is equipped with a digital flight control system, known as Fly-by-Wire, which ensures precise handling and stability during high-speed maneuvers.
The Su-30MKI is equipped with modern avionics and weapons control systems, providing the pilot with real-time situational awareness. A key feature is the H011 “Bars” multi-purpose phased array radar, which can track up to 15 targets simultaneously and engage up to four of them. The aircraft also features advanced electronic countermeasures (ECM), an optical location guidance system, and a laser rangefinder for detecting and engaging targets without radar emissions.
In terms of weaponry, the Su-30MKI can carry an extensive array of air-to-air and air-to-ground missiles. These include the P-77 and P-73 air-to-air missiles, the X-29 air-to-ground missile, and various laser-guided bombs. The aircraft also features a 30-mm GSh-30-1 gun, capable of firing 150 rounds for close air combat.
With an operational range of 3,000 km without aerial refueling, the Su-30MKI is well-suited for long-range missions. When refueled in-flight, its range can be extended significantly, making it ideal for sustained operations. The aircraft can carry up to 8,000 kg of armaments on its 12 external hardpoints, allowing it to perform a wide variety of missions, including air superiority and ground strikes.
