Japan
Japan has also been developing its own fifth-generation air superiority fighter as it looks to replace its ageing F-15s. Developed by the Ministry of Defense Technical Research and Development Institute,
the Mitubishi ATD-X Shinshin project was launched after Washington refused to sell Tokyo the F-22 Raptor. However, the ATD-X (also known as the Mitsubishi F-3) is meant to enter service by the late 2020s.
In the meantime, Japan has ordered 42 F-35s, which are supposed to serve as a stopgap measure between its F-15s and the ATD-X. It is assumed that the Shinshin will incorporate at least some of the F-35’s stealth technology.
If completed, the F-3 is supposed to incorporate some cutting-edge technology. The aircraft will be fitted with an active electronically scanned array (AESA) radar. The radar will have capabilities for electronic countermeasures, communications functions, and possibly even microwave weapon functions. The Shinshin is planned to have a flight-by-optics flight control system. Data is transmitted by optical fibers rather than wires. In this way data is transmitted faster and is immune to electromagnetic disturbance.
Furthermore, the new Japanese aircraft will have a so-called self repairing flight control capability. It will allow the aircraft to detect failures or damage in its flight control surfaces. The system will calibrate remaining control surfaces accordingly to retain controlled flight.
South Korea
South Korea’s next generation fighter is also a long-term project.
The Korea Aerospace Industries KF-X isn’t strictly speaking a fifth-generation aircraft, but is termed as “4,5 generational” platform. The KF-X is an ambitious program, aiming to provide Seoul with a stealth fighter with capabilities better than the best current fourth-generation fighters (including the F-16s it currently possesses), but short of the F-35 and its counterparts. This is probably due to both costs as well as the necessity of having a fighter that will be invisible to North Korean radars, while having enough capabilities to intercept Chinese and even Japanese fifth-generation aircraft.
As previously discussed by Robert Farley for the Diplomat, Seoul has agreed to purchase 40 F-35s, alongside 25 different technologies. This will give Seoul the necessary tech and materials to design and construct the KF-X. However, four of these technologies are currently being withheld due to pressure from the U.S. Congress and defense industries.
According to Farley, “The four technologies in question are the active electronically scanned radar, the infrared search-and-rescue systems, the electro-optical targeting pod, and the radio frequency jammer.
Reports indicate that Korea will attempt to develop the latter two technologies indigenously, and the former two in cooperation with foreign (non-US) industry.”
The reason behind the U.S. reluctance is probably due to the fact the South Korea is hoping to export the KF-X once it’s completed.
Indonesia has already signed up to the program, and will receive 80 fighters once they are completed; Seoul has said that it will field 120 KF-Xs by 2025-2030. If Seoul manages to produce a fighter that actually works, it could present an affordable alternative to the F-35.
However, as Dave Majumdar notes, it is
unlikely that South Korea will be able to develop all of the relevant technologies (or acquire them from other sources) in a timely fashion. The DoD decision could lead to a
cancellation of the entire F-35 deal, which would leave Korea without a fifth-generation fighter for the foreseeable future.
India
The final major indigenously developed Asian fifth-generation fighter is India’s Advanced Medium Combat Aircraft (AMCA), currently under development by Hindustan Aeronautics Limited. As opposed to Japan and South Korea (and China, if the espionage reports are accurate), India doesn’t currently and likely won’t in the future have access to the F-35’s technology. Furthermore, as part of Prime Minister Narendra Modi’s “Make in India” campaign, much of the technology and hardware installed in the AMCA will be indigenously developed.
However, there are speculations that HAL will be able to acquire some of the necessary technology from Russia, which is in the testing stages of its own fifth-generation fighter, the Sukhoi PAK-FA T-50.
The AMCA is supposed to supplement, rather than outright replace, many of India’s current platforms.
Like the F-35, the AMCA is supposed to be a multirole fighter, able to conduct both air-to-air combat and air-to-ground sorties. It will be powered by twin GTRE K-10 turbofans, the successor of the cancelled Kaveri engine. This will be designed and produced with help from a undecided foreign company (
the odds are that this will either be the French Snecma M88 or U.S. General Electric’s F-414.)
HAL is planning to design a carrier-based platform of the AMCA as well. These would probably operate from the new
Vikrant-class aircraft carrier.
According to the Times of India, the AMCA will be ready for testing in 2023-2024.
The next-generation battle for Asia’s skies is on. Which of these birds will prevail over the continent?
