KF-21 Boramae
The KF-21 Boramae, is a fifth-generation multi-role fighter aircraft. Developed by the Korea Aerospace Industries (KAI). In April 2021, the inaugural prototype of the KF-21 Boramae was successfully finalized and revealed to the public. Subsequently, on the 19th of July 2022, the aircraft underwent its maiden test flight, marking a crucial milestone in its development. The commencement of manufacturing is slated for the year 2026.

The Chengdu J-20, also known as the Mighty Dragon, is a twinjet, all-weather stealth fighter aircraft developed by China’s Chengdu Aerospace Corporation. This advanced fighter is specifically designed for air superiority and possesses precision strike capabilities. The J-20 officially entered service in March 2017, marking a significant milestone for China as it became the second country globally and the first in Asia to deploy an operational stealth aircraft.

The avionics system of the J-20 is designed to achieve comprehensive situational awareness by integrating advanced sensor fusion, coupled with stealth and electronic warfare capabilities to deny situational awareness to adversaries. Its integrated avionic suite comprises multi-spectral sensors that deliver omnidirectional coverage.

On the other hand, the KF-21 is equipped with state-of-the-art features such as an AESA radar, advanced avionics, and precision weaponry. Boasting 10 hardpoints for weapons deployment, high maneuverability, enhanced survivability, and a configuration with single tandem aircraft seats, the KF-21 ensures high operational efficiency in diverse mission scenarios.

According to the report, UAE’s Economic Council had sent a letter to South Korea’s Office of National Security explaining Abu Dhabi’s desire for direct cooperation on the development of the KF-21. Surprisingly, the letter allegedly requested that Abu Dhabi replace Indonesia’s investment in the program.

In June, at Chengdu Aircraft Corporation in China, a brand-new J-20 prototype with the serial number 2052 took off with two WS-15 turbofan engines powering it.Influential factors for the PLA’s upcoming sixth-generation fighter project include the WS-15’s progress towards maturity, an upgraded J-20 variant, and higher J-20 production rates.
