South African defense company Paramount is at the forefront of testing the radar system for South Korea’s KF-21 Boramae stealth fighter jet. The radar in question is the Active Electronically Scanned Array (AESA), a critical component of the indigenous KF-21 program. Let’s delve into the details.
The AESA radar represents a significant technological challenge. Initially, South Korea sought to acquire AESA radar technology from the United States. However, export restrictions prevented this, prompting the country to embark on its own radar development journey. The KF-21 AESA radar program marks South Korea’s first foray into AESA radar technology, with potential applications beyond the KF-21.
The KF-21’s AESA radar was developed locally, with Hanwha Systems providing the hardware and LIG Nex1 the software.
Under the auspices of the South Korean Defense Acquisition Program Administration (DAPA), the project involves collaboration between the South Korean Agency of Defense Development (ADD), Hanwha Systems Co (HSC), and Paramount Aerospace Systems. Paramount, acting as a subcontractor alongside Italian aerospace company Leonardo, is responsible for testing the radar.
In December 2021, airborne tests of the KF-21’s AESA radar took place in South Africa. Developers from ADD and HSC participated in these crucial evaluations. Subsequently, in South Korea, airborne tests continued after the modified Boeing 737 arrived in March. The radar was integrated into a new nose section before further testing in South Africa.
The modified Boeing 737 (registration ZS-TFJ, msn 26541) was previously flying for Ceskoslovenske Aerolinie and Czech Airlines, it transitioned to Africa Aircraft Maintenance and was later taken over by Paramount Aerospace Systems. In July 2020, it bore AESA testing markings, although the modified nose was not yet in place.
Between November 2022 and February 2023, the modified Boeing 737 conducted 18 radar test flights, with flight tracking data revealing multiple sorties from Wonderboom.
KF-21 Radar Evaluation
Notably, radar testing is also underway on the KF-21 itself. The KF-21, which made its maiden flight in July 2022, will undergo radar evaluation flights from March 2023 to February 2026. Key parameters include maximum detection range in air-to-air mode, tracking distance, and tracking accuracy.
Future Prospects
South Korea aims to commence mass production of the KF-21 by mid-2026. The Republic of Korea Air Force (RoKAF) anticipates replacing its aging F-4E Phantom and F-5E Tiger II fighter aircraft with a substantial fleet of KF-21s.
The KF-21 incorporates stealth technology, reducing its radar cross-section and enhancing survivability in combat. It features cutting-edge avionics systems, including the AESA radar. This radar provides improved detection and tracking capabilities.
The KF-21 is designed for both air-to-air and air-to-ground missions, making it versatile in various scenarios. It can achieve supersonic speeds without afterburners, allowing for extended range and increased operational flexibility.
The cockpit includes a wide-area display, advanced sensors, and a user-friendly interface for pilots.
Weapon Payload: The KF-21 can carry a variety of weapons, including air-to-air missiles, precision-guided munitions, and stand-off weapons.
With its fly-by-wire control system, the KF-21 exhibits impressive agility and maneuverability.
South Korea’s commitment to developing its own fighter jet showcases its technological prowess and self-reliance.
