South Korea to deliver first KF-21 Boramae fighters in 2026

South Korea is preparing to deliver the first production KF-21 Boramae fighter jets to the Republic of Korea Air Force (ROKAF) this year, marking the transition of the country’s flagship combat aircraft program from development to operational service.

According to South Korean media, the first serial-production aircraft are expected to be handed over in 2026 following the completion of acceptance testing. The deliveries will mark the first induction of an indigenous fighter mainly developed by the South Korean industry, led by Korea Aerospace Industries (KAI).

From development program to operational aircraft

ROKAFThe KF-21 program, also known as KF-X, has been one of South Korea’s most ambitious defense projects, aimed at replacing aging F-4 Phantom II and F-5 Tiger II fleets while reducing reliance on foreign combat aircraft.

After the maiden flight of the first prototype in 2022, the test campaign progressed through multiple flying prototypes, validating flight performance, avionics, and mission systems. Serial production formally began in 2024, with final assembly of the first operational aircraft taking place in 2025.

The initial deliveries will consist of Block I aircraft, optimized primarily for air-to-air missions. These jets are expected to achieve an initial operational capability before being followed by more capable Block II variants later in the decade.

Indigenous systems at the core of the program

Defense Acquisition Program AdministrationA central objective of the KF-21 effort has been the development of domestic aerospace technologies. The aircraft integrates a locally developed active electronically scanned array (AESA) radar, mission computer, electronic warfare suite, and flight control systems.

The KF-21 configuration emphasizes reduced radar signature, advanced sensor fusion, and networked operations, positioning it as a so-called 4.5-generation multirole fighter tailored to South Korea’s operational requirements.

The aircraft is also expected to gain progressively expanded strike capabilities, including integration of air-to-ground weapons and stand-off munitions, as the program moves into its Block II phase.

The program is also closely watched internationally. South Korea has positioned the KF-21 as a potential export platform, particularly for air forces seeking a modern fighter without the political, financial, or production constraints often associated with other aircraft.The post South Korea to deliver first KF-21 Boramae fighters in 2026 appeared first on AeroTime.
