India's TEJAS Light Combat Fighter Jet

Fighter aircraft, like every facet of military technology, are rapidly evolving. The current global and regional transition from fourth to fifth-generation fighter aircraft, like the F-22 Raptor and F-35 Joint Strike Fighter platforms, is reshaping the role of fighter fleets and the balance of power in Australia's region. 

Designed to establish and maintain air superiority or air dominance, fighter aircraft have evolved from relatively simple, wood and canvas air frames during the First World War, to the highly manoeuvrable, long-range aircraft that dominated the skies of Europe and the Pacific during the Second World War; the latest two generations of fighters are the pinnacle of these earlier designs. 

Indo-Pacific Asia's fighter fleets are made up of fighter aircraft ranging from third to fifth-generation aircraft, each with unique capabilities and roles within the regional balance of power. 

Before we dive into the regional fighter fleets, let's take a closer look at the differences between the generations of aircraft operating in our region:

Third-Generation Fighter: Designed and developed between the early 1960s and the 1970s, these aircraft placed renewed focus on manoeuvrability and traditional ground attack capabilities. Third-generation aircraft also saw the increased use of guided missiles in combat, the introduction of analogue avionics systems and improved aerodynamic performance. Examples of third-generation fighter aircraft include the US F-4 Phantom II, the French Mirage F1, the Russian MiG 25 Foxbat and Chinese Shenyang J-8.

Fourth-Generation Fighter: Developed and in service from about 1980 until the present, fourth-generation fighter aircraft placed renewed emphasis on manoeuvrability and air-to-air combat capability, supported by improved fly-by-wire flight control systems, improved avionics, the introduction of digital computers, aerodynamic air frames and on board radar systems to leverage advances made in long-range air-to-air missiles. Fourth-generation combat aircraft also marked the the introduction of multi-role fighter aircraft. Examples of fourth-generation fighter aircraft include the US F-15 Eagle, F-14 Tomcat, F/A-18 Hornet, Russian MiG-29 and Su-27, French Rafale, Eurofighter Typhoon and Chinese Shenyang J-10 and J-11.

4.5 Generation Fighter: Evolved variants of the fourth-generation, incorporating advances in microchip and semiconductor technology to improve avionics, radar, data links and network-centric warfare. Additionally, these aircraft incorporate advances in radar cross section reducing design and materials, advanced GPS guided weapons and in some cases thrust vectoring. Examples of 4.5 generation aircraft include the US F-15E Strike Eagle and F/A-18 E/F Super Hornet, the Russian Su-30MKI and MKK variants, Eurofighter Typhoon and Rafale variants.

Fifth-Generation Fighter: The pinnacle of fighter aircraft, incorporating all-aspect stealth even when armed, low-probability-of-intercept radar, high-performance air frames, advanced avionics and highly integrated computer systems, these aircraft provide unrivalled air dominance, situational awareness, networking, interdiction and strike capabilities for commanders. Examples of fifth-generation aircraft include the US F-22 Raptor and F-35 Joint Strike Fighter, Russian Su-57 and Chinese J-20 and FC-31.

In the first instalment, we will take a closer look at the operational fighter fleets of China, Russia and India. 

People's Liberation Army Air Force

China's Air Force has undergone a period of modernisation and expansion in line with the country's growing ambitions in Indo-Pacific Asia. Part of this program has seen an expansion in the PLAAF's fourth-generation aircraft fleets and increased investment and development of domestically designed fifth-generation platforms.

As the largest air force in Asia, the PLAAF operates about 3,000 aircraft of various roles, with a diverse fleet of multi-generation fighter aircraft, including:

Indian Air Force

The Indian Air Force, like its Russian and Chinese counterparts, is undergoing a series of modernisation and recapitalisation programs to phase out older generation fighter aircraft with foreign designed and manufactured fighter aircraft. India's pursuit for a modern fighter force also aims to help develop the country's own aerospace manufacturing industry.

India's Air Force incorporates a variety of fighter aircraft designed by French, Russian and domestic manufacturers, including: 

Mikoyan MiG-29: Designed in the mid-1980s, the MiG-29 aircraft serves the Indian Air Force with an early-fourth-generation multi-role fighter aircraft similar to the American F-16 and F/A-18 series fighter aircraft. The MiG-29 has a range of about 2,100 kilometres and max speed of Mach 1.13 (at sea level) and 2.25 (at high altitude) and is armed with a single 30mm cannon and nine hardpoints for carrying a variety of Russian and Indian made air-to-air, air-to-ground and air-to-surface munitions, including 'dumb' and 'smart' bombs with a maximum load capacity of about 12,000 pounds.

The Tejas has a combat radius of 500 kilometres and max speed of Mach 1.8 (full-rate production model), and is armed with a single 23 mm cannon and eight hardpoints for integrating a range of Russian and Indian air-to-air, air-to-ground and air-to-surface munitions, including 'dumb' and 'smart' bombs. 

India's Air Force modernisation program will see a number of continuing transformations, including the introduction of a fifth-generation fighter aircraft. Designated the Advanced Medium Combat Aircraft, it is designed to complement fourth- and 4.5 generation fighter aircraft and replace the ageing Mirage 2000 aircraft. 

Additionally, the Indian Air Force is looking to introduce 200 new, single-seat, single-engine fighter aircraft, with the Lockheed Martin F-16 Block 70 and Saab Gripen fighter aircraft. It is expected that the procurement will also see increased Indian industry involvement as part of the Indian government's goal of developing a capable domestic aerospace and advanced manufacturing industry. 

Russian Air Force

Russia's Air Force has inherited a variety of Soviet-era fighter aircraft designs, which has up until recently placed the Air Force at a disadvantage as regional nations introduce more advanced aircraft into their own fleets.

However, the growing modernisation and rearmament of the Russian armed forces as a whole, has seen a rapid modernisation of the Russian fighter fleet, to incorporate a range of highly advanced and capable fourth- and 4.5 generation aircraft, with research and development and low-rate, initial production of a domestically designed fifth-generation platform, including:

Sukhoi Su-27: A twin-engine, super-manoeuvrable fighter aircraft designed to counter American fourth-generation fighters like the US F-14 and F-15 aircraft. The Russian Air Force operates a variety of the Su-27 variants across its 37 fighter squadrons. The Su-27SK variant, which serves as the base model for the Russian operated variants, has a range of between 1,340 kilometres (at sea level) and 3,530 kilometres (at altitude) and a max speed of Mach 2.35. The aircraft is armed with a single 30 mm cannon and has 10 hardpoints capable of carrying a range of Russian made air-to-air, air-to-ground and air-to-surface munitions, including 'dumb' and 'smart' bombs with a maximum load capacity of about 10,000 pounds.

Sukhoi Su-34: A Soviet answer to the F-111 fighter-bomber, the Su-34 provides the Russian Air Force with a credible, high-capability, long-range fighter-bomber. The Su-34 has a combat range of about 1,100 kilometres, a top speed of Mach 1.8+ and is armed with a single 30mm cannon. As a fighter-bomber, the Su-34 has 12 hardpoints capable of carrying a range of Russian made air-to-air, air-to-ground and air-to-surface munitions, including 'dumb' and 'smart' bombs with a maximum load capacity of about 17,600-26,500 pounds.

Sukhoi Su-35: An evolution of the Su-30 series, the Su-35, like the capability delivered to the Chinese Air Force, provides the Russian Air Force with a 4.5 generation fighter aircraft, incorporating thrust vectoring engines with a max speed of Mach 2.25 and combat range of about 1,580 kilometres. The aircraft are armed with a single 30 mm cannon and are equipped with 12 hardpoints capable of carrying a variety of Russian made air-to-air, air-to-ground and air-to-surface munitions, including 'dumb' and 'smart' bombs with a maximum load capacity of about 18,000 pounds.

Mikoyan MiG-29: Designed in the mid-1980s, the MiG-29 aircraft provides the Russian Air Force with an early-fourth-generation multi-role fighter aircraft similar to the American F-16 and F/A-18 series fighter aircraft. The MiG-29 has a range of about 2,100 kilometres and max speed of Mach 1.13 (at sea level) and 2.25 (at high altitude) and is armed with a single 30 mm cannon and nine hardpoints for carrying a variety of Russian made air-to-air, air-to-ground and air-to-surface munitions, including 'dumb' and 'smart' bombs with a maximum load capacity of about 12,000 pounds.

Mikoyan MiG-31: Designed at the height of the Cold War as a high-altitude, high-speed fighter interceptor to counter high-altitude US strategic bombers, the MiG-31 has a combat range of 1,450 kilometres with a max speed of Mach 2.83 and can be armed with a variety of Russian made air-to-air and air-to-surface munitions.

Sukhoi Su-57: Russia's answer to the American F-22 Raptor and the Chinese J-20, the Su-57 is intended to succeed the MiG-29 and Su-27 series fighters in Russian service. The twin-engine, multi-role air superiority fighter aircraft is the first Russian aircraft to incorporate radar reducing cross sections and materials, high-capacity sensor integration and advanced engines. Su-57 has a supersonic range of about 1,500 kilometres and subsonic range of 3,500 kilometres and max speed of Mach 2. The aircraft is armed with a single 30 mm cannon and between 12 and 16 hardpoints, including internal weapons bays capable of Russian made air-to-air, air-to-ground and air-to-surface munitions, including 'dumb' and 'smart' bombs.

Despite modernisation efforts made by the Russian government, significant recapitalisation programs for Soviet-era platforms like the MiG-31 and Su-27 series fighter aircraft will see a series of advanced 4.5 and fifth-generation combat fighter aircraft, including the Su-57; the 4.5 generation MiG-35, an evolution of the MiG-29; and the MiG-41 a fifth-generation, high-altitude, high-speed interceptor replacement for the MiG-31 expected to be introduced into service 2025.

This expansion is planned to be supported by expanding the export success of Russia's fighter aircraft, with the Su-57 and modernised variants of the Su-27 and Su-30/35 series fighter aircraft enabling the Russian Air Force to lower the research and development and corresponding unit costs for advanced platforms moving forward.
