With the aim of significantly strengthening security on NATO's eastern flank.
The Polish Air Force has officially placed South Korean-made FA-50GF light fighter jets on combat duty with the aim of significantly strengthening security along the country’s eastern border and on NATO’s flank.
Polish Minister of National Defense Władysław Kosiniak-Kamysz announced the start of official combat duty for the South Korean-made FA-50GF light fighter jets along the country’s eastern border. The Polish official reported this on his page on the social media platform X (Twitter).
“The FA-50GF light combat aircraft have just begun combat duty. This marks another step toward strengthening our eastern border,” wrote the head of the Polish Ministry of Defense.
According to the minister, the South Korean FA-50GF light combat aircraft have already been integrated into the Polish Air Force’s field combat duty. Kosiniak-Kamysz also noted that the introduction of new equipment is an important step toward strengthening Poland’s defense capabilities, especially along the eastern border.
It is known that Poland initially received these aircraft unarmed, but the country subsequently managed to acquire the necessary armaments. Thus, the FA-50GFs can now be used to defend Polish airspace.
“Although the aircraft were acquired without weapons, we managed to obtain them, thanks to which they can now serve our defense,” the minister noted.
The head of the Ministry of Defense also expressed gratitude to the military personnel who ensured the operational readiness of the aircraft and their integration into the combat readiness system, noting that Poland now has “new defenders.”
What is known about the Polish FA-50GF
The FA-50 Fighting Eagle is a light multi-role fighter developed by the South Korean company Korea Aerospace Industries (KAI) based on the T-50 trainer aircraft. The aircraft is designed to combine training missions with full-fledged participation in combat operations.
Poland has ordered a total of 48 aircraft from the FA-50 family. This includes 12 FA-50GF aircraft and 36 aircraft in the future FA-50PL configuration.
The abbreviation GF stands for “Gap Filler.” These 12 aircraft were intended to quickly bolster the Polish Air Force until the arrival of the more advanced FA-50PL version. Poland received the first aircraft in 2023.
The Polish parliament noted that the 12 FA-50GF aircraft are based at the 23rd Tactical Air Base in Minsk-Mazowiecki. The aircraft have been in service with the Polish Air Force since September 2023.
The Polish Ministry of Defense describes the FA-50 as a light combat aircraft equipped with modern avionics and a fire-control radar. The aircraft is equipped with a 20-mm cannon and can carry air-to-air and air-to-ground guided weapons, including the AIM-9 Sidewinder and AGM-65 Maverick missiles.
According to the Polish Ministry of Defense, the FA-50’s maximum speed is approximately Mach 1.5, and its combat payload can reach 4.5 metric tons. The aircraft is also equipped with the Link 16 data link system and a NATO-standard “friend-or-foe” identification system.
Background on the FA-50 procurement
Poland made the decision to procure the FA-50 in 2022. On July 27, 2022, Warsaw signed a framework agreement with the South Korean company KAI for the delivery of 48 aircraft and subsequently concluded an implementation contract for the first 12 FA-50GFs.
The Polish Ministry of Defense explained the phased procurement as necessary to rapidly strengthen the capabilities of the Air Force. The first 12 aircraft were intended to immediately fill the existing gap, while the next 36 aircraft are to be equipped with enhanced capabilities and meet the FA-50PL standard.
According to the Polish Sejm, deliveries of the 36 FA-50PL aircraft are scheduled for 2026–2028.
At the same time, the FA-50’s entry into combat duty followed extensive preparation. As early as August 2025, the Polish Ministry of Defense reported that 2026 was to be the year the FA-50 would transition to combat duty.
Thus, as of October 2, the Polish FA-50GFs officially began combat duty, and their mission is specifically aimed at strengthening Poland’s eastern border.
