The KF-21 Boramae, a multirole fighter developed by Korea Aerospace Industries (KAI), is emerging as one of the most promising contenders in India’s Multi-Role Fighter Aircraft (MRFA) selection program.
According to reports from the Indian defense media published on August 1, the South Korean jet is being actively evaluated by the Indian Air Force (IAF), which is looking to fill growing gaps in its combat aircraft fleet.
With a goal of acquiring at least 60 advanced 4.5-generation fighters, New Delhi considers the KF-21 a competitive platform in terms of both cost and strategic potential. The aircraft features an AESA radar, infrared search and track (IRST) system, electronic warfare capabilities, and compatibility with modern weaponry. Its modular design also allows for future upgrades, including internal weapons bays and stealth coating, as envisioned for Block III.

Powered by two General Electric F414-400K engines, the KF-21 reaches a top speed of Mach 1.8, a combat radius of approximately 1,500 nautical miles, and can carry up to 7,700 kg of armaments. One of its key advantages, according to Indian media, is the use of the same F414 engine already selected for India’s Tejas Mk II and AMCA programs, which could simplify logistics, maintenance, and operational integration.
Originally developed in 2011 as a response to South Korea’s aging F-4 and F-5 fleets, the KF-21 entered flight testing and is expected to have its first units delivered to the Republic of Korea Air Force by 2026. Although initially conceived as a fifth-generation fighter, the project was adapted to prioritize a 4.5G configuration to meet urgent operational needs.
In addition to its technical capabilities, the South Korean jet aligns with India’s “Make in India” industrial policy, offering potential for local assembly or co-production. The KF-21’s open architecture would allow integration of Indian-developed systems such as the Uttam AESA radar and Astra missiles, provided source code and software access agreements are reached.
Cost-wise, the estimated unit price of the KF-21 ranges between US$ 87 million and US$ 110 million, including engines — lower than competitors such as the Rafale, Su-57, and F-35. In July, Bloomberg reported that India informed the U.S. it was not interested in acquiring the F-35, despite repeated proposals from Washington.
With the imminent retirement of aircraft such as the MiG-21 and Jaguar, the IAF faces a critical reduction in its combat capability, accelerating the search for new solutions. In this context, the KF-21 Boramae stands out as a viable and strategic alternative to strengthen India’s air defense.
