Korea Aerospace Industries confirmed talks with the Philippines after the KF-21 Boramae’s flight display at Seoul ADEX 2025. Manila’s interest reflects growing defense ties with South Korea as it modernizes its air force amid rising tensions in the West Philippine Sea.
The South China Morning Post disclosed on October 27, 2025, that Korea Aerospace Industries (KAI) said it is in talks with the Philippines following the KF-21 Boramae’s flight demonstrations at Seoul ADEX 2025, where a Philippine delegation watched South Korea’s newest multirole fighter perform. The company highlighted Manila’s recent move to double its FA-50 fleet, signaling momentum for deeper industrial ties. The story positions KF-21 as a near-term export contender while recalling the Philippine Air Force’s reliance on Korean-made FA-50s for air policing, maritime patrol overwatch, and limited strike tasks. If pursued, KF-21 would add beyond-visual-range punch with Meteor-class missiles and grow into precision strike as Block 2 matures.Follow Army Recognition on Google News at this link

KF-21 is a twin-engine 4.5-generation design built around two GE F414s and a domestic sensor suite that includes a Hanwha Systems active electronically scanned array radar, infrared search and track, and a modern electronic warfare package. The baseline Block 1 prioritizes air-to-air performance with semi-recessed fuselage stations that reduce drag and signature for long-range intercepts. Flight testing has already fired IRIS-T and conducted separation and firings for Meteor, establishing the airframe’s BVR credentials. South Korea has also moved to integrate European standoff weapons under a KAI-MBDA framework, expanding the options for export users.
Block 2, which Seoul aims to accelerate, adds guided bombs and indigenous cruise missiles, pushing KF-21 into a true swing-role profile. A follow-on variant is being engineered with internal bays, improving survivability when penetrating layered air defenses. The production cadence is firming at home after contracts for initial batches, with first ROKAF deliveries planned in 2026, a timeline that reassures prospective buyers about schedule credibility. Aircraft availability and munitions integration windows often decide whether a modernization program yields near-term deterrence or remains aspirational.
Any Philippine KF-21 bid would sit beside two familiar options. Washington cleared a potential sale of 20 F-16 Block 70/72s this spring, a package built around APG-83 AESA radar and the latest AIM-120 class weapons, albeit with a high headline price that strains Manila’s budget. Saab, for its part, has kept a Gripen conversation alive with Manila, emphasizing the type’s agile dispersed operations concept, quick turnarounds, and proven Meteor integration, while cautioning that global demand could lengthen delivery queues. Manila has already deepened the “high-low mix” with 12 additional FA-50s on order, suggesting a Korean pathway could reduce logistics friction and training overhead if KF-21 becomes the high end of the spectrum.
The South Korean KF-21 would change how the Philippine Air Force operates. Twin-engine safety is not academic over the West Philippine Sea, where long overwater sorties are routine. With Meteor-class reach cued by AESA and IRST, KF-21 offers credible area denial over disputed features, escorts for maritime patrol aircraft, and rapid response to incursions. As Block 2 brings JDAM- and SDB-class munitions and indigenous standoff missiles online, the jet could generate sea-control effects by cueing or striking maritime targets at range, complementing coastal missile batteries and FA-50s that handle day-to-day air policing. If paired with planned enablers like tankers and airborne early warning, Manila could sustain combat air patrols deeper into its exclusive economic zone and knit a real kill chain across services.
China’s coast guard and militia activity around Second Thomas Shoal and elsewhere has intensified, drawing U.S. and allied backing while forcing Manila to harden its posture. Each resupply run, each close-quarters confrontation, underlines a basic truth for the Philippines: deterrence in the air shapes behavior at sea. A modern multirole fleet with BVR reach and survivable sensors raises the cost of coercion, tightens coordination with treaty allies, and gives Manila options short of escalation. That is the subtext of the KF-21 conversation after ADEX, and why the Air Force’s fighter choice will reverberate well beyond the flight line.
