The Defense Acquisition Program Administration presented its KF-21 S1000D electronic technical-manual work at an international S1000D forum on September 28, 2026 and said it will apply the international-standard approach to other export weapon systems, including the K2PL tank for Poland and the K9 howitzer. S1000D-compliant manuals let foreign operators integrate Korean equipment into their own logistics and training systems, which DAPA describes as a way to support follow-on logistics and sustainment revenue on export programs. The KF-21 was the first Korean weapon system to be documented fully to the standard.
KDReview's watchlist for the fourth quarter of 2026. Malaysia's first two FA-50M jets are due at Kuantan Air Base in October, with the 18-aircraft order completing by March 2028. Iraq's review of up to 250 K2 tanks (about $6.5 billion) remained unsigned as of July, with analysts expecting a 2026 signature. Romania's 216-tank tender awaits a localization study. Peru's K2 and K808 implementing contract is suspended over a $1.5 billion advance payment. Indonesia's 16 KF-21s and the Philippines' two submarines are unsigned. In Saudi Arabia, Hanwha Defense Arabia is targeting a roughly KRW 15 trillion National Guard land-forces modernization with K9 and Chunmoo, while Hanwha Ocean weighs four to six submarines and five frigates. Thailand's OCEAN-40F frigate award to Hanwha Ocean faces rival complaints before a final contract. On the calendar: Armed Forces Day on October 1 at Gyeryongdae with AI-enabled weapons on display and no parade, and the first K-DEX on December 8 to 11 at KINTEX, where eleven countries including the US, Saudi Arabia, India, Norway, Finland, and Latvia will brief on procurement.
|KDReview roundup (Korea Herald, Malay Mail, Seoul Economic Daily, BusinessKorea, Asian Military Review)
The Defense Acquisition Program Administration issued a tender, reported September 24, 2026, for a 14-month, roughly 900 million won concept study of a Korean next-generation fighter covering manned-unmanned teaming, broadband L-, S-, and X-band stealth, a tailless configuration, an adaptive variable-cycle engine, and internal weapons bays. Some officials instead favor a fifth-generation-class KF-21 upgrade, referred to as KF-21EX-T, arguing that a nearer-term evolution of the Boramae would keep the type competitive in export campaigns in Indonesia, the Middle East, and Southeast Asia while a clean-sheet sixth-generation design would not fly until the 2040s. The tender formalizes the request for proposals DAPA released on August 21.
Korea Aerospace Industries handed over the first production KF-21 Boramae to the Republic of Korea Air Force on September 22, 2026, ten years and nine months after system development began in December 2015. The two-seat Block I aircraft, flown by Maj. Han Jae-seok, departed KAI's Sacheon plant escorted by an FA-50, a TA-50, and a T-50 and landed at Yecheon Air Base, where it joins the 156th Fighter Squadron of the 16th Fighter Wing, reactivated on June 1, 2026 for the type. The Air Force plans to declare operational capability in the second half of 2027, field 40 Block I aircraft by 2028 and 80 Block II by 2032, and eventually operate more than 100 KF-21s. Sources differ on the tail number, reported as either 25-001 or 26-001.
Korea Aerospace Industries and PT Dirgantara Indonesia signed an industrial cooperation agreement, reported September 21, 2026, under which PTDI will build 15 percent of KF-21 airframe components. Both companies are still pursuing a contract with Indonesia's Ministry of Defence for 16 KF-21s worth about $2.9 billion (KRW 4.01 trillion), announced during President Prabowo's March 2026 visit but not yet signed. Indonesia completed its KRW 600 billion development-cost share on June 25, 2026, and the first three jets are expected in late 2028 or early 2029. Next milestone: contract signing, date unknown.
Korea Aerospace Industries opened its KF-21 Boramae final assembly line in Sacheon to reporters on September 15, 2026, ahead of the first delivery to the Republic of Korea Air Force expected around the end of September during the Chuseok holiday period. About eight production aircraft are due to be handed over in 2026, with the first 40 Block I fighters complete by 2028 and a further 80 by 2032 for a planned fleet of 120. Roughly 30 technicians assemble each airframe largely by hand over about six months on a line sized for more than 20 aircraft per year, routing some 40 kilometers of wiring per jet and drilling 3,400 holes to join wings to fuselage at a tolerance of one-thousandth of an inch. KAI noted that its trainer and fighter programs, from the KT-1 and T-50 through the FA-50 and KF-21, have logged 10,000 cumulative test-flight hours since 2005 without an accident, and said it is preparing additional production capacity should export demand from Indonesia, the UAE, the Philippines, Malaysia, or Peru exceed the current line. Separately, KAI is beginning to fabricate parts this month to convert an FA-50 prototype into a single-seat variant with extra fuel in place of the rear cockpit, targeting ground tests in 2028.
The Cabinet approved a 73.28 trillion won ($51 billion) defense budget for 2027 on September 1, 2026, an 8.2% increase from 67.7 trillion won in 2026 and the first time the total has crossed 70 trillion won. The force-improvement portion tied to the wartime operational control (OPCON) transfer rises to 21.3 trillion won from 18.6 trillion won, funding command-and-control upgrades, surveillance drones, and L-SAM long-range interceptors. KF-21 Boramae production funding jumps to roughly 3.3 trillion won from 1.4 trillion won, with an additional 150 billion won earmarked for follow-on production. Nearly 100 billion won is allocated for the first time to the Jangbogo-N nuclear-powered submarine program, covering initial design and nuclear-related reviews. Defense AI spending more than doubles to 361 billion won for drone swarms, attack drones, and counter-drone systems, and the number of full-time reservists nearly doubles from 3,700 to 7,000. Defense spending would reach 2.33% of GDP, still well short of the government's stated 3.5% target. The bill was submitted to the National Assembly on September 3.
DAPA released a request for proposals on August 21, 2026 for a 14-month, roughly 900 million won ($650,000) conceptual study of a South Korean sixth-generation fighter. The study will examine two parallel stealth configurations — one tailless and one with alternative control surfaces — for a single-seat aircraft with low observability across L, S, and X bands, twin adaptive-cycle engines, and an internal weapons bay. Fielding is not expected before 2040 and no full program launch decision has been made, but the study marks the formal start of thinking beyond the KF-21 Boramae just weeks after that program completed system development. Analysts see it as a signal that Korea intends to stay in the top tier of fighter developers alongside the US, Europe, and Japan.
KAI and Hyundai Rotem signed a memorandum of understanding at KAI headquarters in Sacheon on August 12 covering joint development and systems integration of advanced airborne munitions with aircraft platforms including the KF-21, plus combined aircraft-and-weapons export packages. Hyundai Rotem takes guided-weapons and propulsion technologies; KAI supplies aircraft-platform integration. The underlying long-range air-to-air missile program is led by the Agency for Defense Development, runs from 2026 to 2033 following Defense Project Promotion Committee approval in late 2025, and is intended to cut ROKAF dependence on imported beyond-visual-range missiles such as the MBDA Meteor. This is KAI's third major weapons-integration partnership of 2026, after agreements with Hanwha Aerospace and LIG Nex1 signed in February at the World Defense Show in Riyadh.
DAPA Commissioner Lee Yong-chul presented the agency's second-half 2026 policy report to President Lee Jae-myung at the Blue House state guest house on August 5, alongside the Ministry of National Defense and Military Manpower Administration, under the theme of an "irreplaceable Republic of Korea." DAPA set five core tasks: securing key forces for self-reliant defense, innovating toward rapid and open acquisition of advanced capabilities, nurturing future security innovation firms, building a co-prosperous defense industrial base, and strengthening international cooperation and export support for K-defense. Concrete commitments include establishing the nuclear-powered submarine (Jangbogo-N) business plan within 2026 using the KSS-III development organization, moving unmanned systems and counter-drone system acquisition into full swing, and fielding three-axis capabilities such as the KF-21 and the long-range artillery interceptor (LAMD) on schedule.
Three K2 tanks and six K808 wheeled armored vehicles built by Hyundai Rotem for export were displayed at Peru's Independence Day military parade in Lima over two days from July 28, 2026 — appearing at the official event even before a final export contract has been signed. The vehicles fall under the framework agreement signed in December 2025 between Hyundai Rotem and Peruvian state firm FAME S.A.C. covering 54 K2s and 141 K808s worth roughly $2 billion, with a $270 million local plant investment and 30% local content. Defense industry officials now see a high possibility of concluding the K2 implementation contract in the second half of 2026 as Peruvian politics stabilize, and note KAI could pair it with a package proposal combining the FA-50 and KF-21 for Peru's fighter acquisition project.
With KF-21 system development formally complete, KAI said the first two production Boramae fighters are undergoing verification flights and are expected to be handed to the Republic of Korea Air Force around September-October 2026, with eight jets due by year-end. The company is also positioning for a follow-on production order from Seoul beyond the initial 20-aircraft Block I contract, while export talks with Indonesia continue despite Jakarta scaling back its commitment. The first delivery will mark the KF-21's transition from development program to operational fighter, a decisive proof point for export campaigns in the Middle East, Southeast Asia, and Europe.
Korea Aerospace Industries and the Defense Acquisition Program Administration held the KF-21/IF-X System Development Completion Ceremony at KAI headquarters in Sacheon, South Gyeongsang, on July 29, 2026, formally closing the roughly ten-year development program launched in 2015. About 300 people attended, including DAPA Minister Lee Yong-chul, Ministry of National Defense, Agency for Defense Development and ROK Air Force officials, representatives of some 500 domestic partner companies, defense ministry and PTDI officials from co-development partner Indonesia, and technical partner Lockheed Martin. The program completed basic and detailed design, prototype manufacturing, ground testing and flight testing, logging more than 1,600 flight trials and verifying over 13,000 test conditions without a single accident, and passed combat suitability certification in May 2026 followed by initial type certification. The 8.8 trillion won ($6.04 billion) effort, begun to replace ageing F-4 and F-5 fleets, now moves into full-rate production: the first mass-production aircraft is scheduled for delivery to the ROK Air Force around September 2026, with an initial batch of 40 air-to-air-capable jets by 2028 and a further 80 enhanced aircraft by 2032 toward a 120-aircraft target.
Indonesia has shifted from co-producing the KF-21 to buying finished aircraft, materially narrowing what was meant to be the program's anchor export. Jakarta cut its development cost contribution to 600 billion won and reduced the scope of technology transfer, and its expected purchase volume has fallen to roughly 16 units worth about 3 trillion won — down from the original plan of 48 aircraft assembled domestically. Budget constraints drove the retreat, and Indonesia has simultaneously signed for Italian M-346FA light combat aircraft while reportedly weighing French Rafales, U.S. F-15s, Turkish Kaan fighters, and Chinese J-10Cs. KAI President Kim Jong-chul has said negotiations across Southeast Asia and the Middle East exceed 200 units, with the Philippines, UAE, and Malaysia also in discussions, but analysts frame the Indonesian outcome as the first real test of whether Korea can convert KF-21 interest into finished-aircraft exports.
South Korea's KF-21 Boramae supersonic fighter has formally completed its system development phase, closing out roughly ten years of prototype manufacturing and flight testing that began in 2015. The Defense Acquisition Program Administration scheduled a "KF-21/IF-X System Development Completion Ceremony" for July 29 at Korea Aerospace Industries in Sacheon, Gyeongnam, with Ministry of National Defense, Joint Chiefs of Staff, and Air Force officials attending alongside Indonesian defense and embassy representatives from the co-development partner. The milestone moves the program into full-rate production and export marketing: the ROK Air Force plans to induct roughly 120 aircraft by 2032, with about 10 this year, 30 by 2028, 40 by 2030, and 40 by 2032. Block-II upgrades covering engine, avionics, and weapons integration are targeted for completion by 2028. The first mass-production aircraft rolled out on March 25, 2026, and Air Force deliveries of air-to-air-capable Block-I jets begin in the second half of 2026.
A Korean defense-industry official said the KF-21 Boramae's first export contract "will be announced soon," with Indonesia (reportedly around 16 units, roughly 3 trillion won), the UAE, the Philippines, and Malaysia cited as leading candidates; KAI President Kim Jong-chul said talks covering 200-plus aircraft are underway. Full-scale mass production is running, and the first mass-produced KF-21 is due to be delivered to the Republic of Korea Air Force in September 2026. KAI plans a "KF-21/IF-X System Development Completion Ceremony" in late July. No binding export contract has been signed yet — the first-customer decision remains a watch item.
LIG Nex1, through its LIG D&A defense arm, presented a roughly $2.8 billion "Total Missile Package" for the KF-21 to about 250 government, military, and industry representatives at the OSCO Convention Centre in Cheongju, aimed at replacing European air-to-air and long-range weapons with indigenous Korean munitions. The bundle covers domestic beyond-visual-range and precision-strike missiles integrated to the KF-21, reducing export and supply-chain dependence on foreign missile makers. It follows Cheonryong safe-separation integration trials on FA-50 platforms in late June that demonstrated roughly one-meter point-target accuracy.
Hanwha Aerospace and Korea Aerospace Industries (KAI) formalized a comprehensive partnership to advance Korea's defense and aerospace businesses across four pillars: joint development and export promotion of unmanned aircraft, development and joint marketing of aircraft integrating domestically produced engines and radars, joint entry into the global commercial space market, and cultivation of the defense/aerospace industrial ecosystem and regional supply chains. The two companies pledged to jointly discover and nurture SMEs and startups in the Gyeongnam cluster (Changwon, Geoje, Sacheon), providing annual technology support worth 300 billion won through joint R&D organizations. Industry watchers framed the tie-up — backed by Hanwha's roughly 2.5 trillion won investment in KAI shares — as assembling an air-land-sea integrated defense powerhouse aimed at the global export market, with a KF-21 export package seen as an early priority.
DAPA granted initial type certification to the KF-21 Boramae on June 15, described as the government's "final official recognition" of the aircraft's flight safety. The fighter met all 745 inspection requirements across 14 airworthiness categories including aircraft structure, weapons integration, and electronic systems. With formal system development concluding in June 2026, KAI is on track to deliver the first production KF-21 to the ROKAF in September 2026.
The US State Department approved a potential $292 million sale of 70 AIM-120C-8 AMRAAM air-to-air missiles and related equipment to South Korea. The missiles will equip ROKAF fighters including the KF-21 Boramae and F-15K Slam Eagle, bolstering air defense capabilities amid growing North Korean threats. North Korea's foreign ministry condemned the sale, warning it would worsen peninsula tensions.
DAPA announced that the KF-21 Boramae has met all criteria of its final combat suitability evaluation, clearing the Block I air-to-air variant for operational deployment after roughly 1,600 test flights and 13,000+ test conditions including aerial refueling and live weapons release. System development is set to conclude in June 2026, with the first mass-produced aircraft scheduled for delivery to the ROKAF in the second half of the year. This makes the KF-21 South Korea's first indigenous combat aircraft to achieve full combat approval.
Hanwha Aerospace raised its ownership of Korea Aerospace Industries (KAI) to 5.09%, crossing the 5% threshold that triggered a mandatory disclosure revising its investment purpose from "simple investment" to "participation in management." The company signaled plans to acquire an additional 500 billion won worth of KAI shares by year-end, which could lift its stake to around 8%. Hanwha is a primary KF-21 partner, producing engines under license and developing the AESA radar, IRST, and electro-optical targeting pod.
The first serial-production KF-21 Boramae fighter jet completed its maiden flight on April 15, 2026, at the ROKAF 3rd Training Wing in Sacheon — just 22 days after its official rollout ceremony on March 25. No anomalies were reported during the sortie. The milestone followed approximately 1,600 prototype test flights completed without accident between July 2022 and early 2026. Following acceptance trials and certification, deliveries to the ROKAF are planned to commence in September 2026, with 40 Block I units scheduled. KAI plans to deliver 31 aircraft in 2027 and 47 in 2028, with full operational capability targeted for 2028.
South Korea reached a working-level agreement to transfer the fifth KF-21 Boramae prototype to Indonesia, formalizing a revised financial settlement disclosed through DAPA documents submitted to the National Defense Committee. Indonesia has paid 536 billion won of a reduced 600 billion won contribution, with the remaining 64 billion won due by June 2026. The transfer advances negotiations for a separate 16-aircraft export contract.
South Korean President Lee Jae-myung and Indonesian President Prabowo Subianto agreed to strengthen collaboration in energy, strategic industries, and defense during an April 1 summit. The leaders congratulated the KF-21/IF-X joint development program on its upcoming completion in June and the two countries signed 16 memorandums of understanding, marking a deepening Indo-Pacific defense partnership.
South Korea is finalizing its first KF-21 Boramae export agreement with Indonesia for 16 fighters around President Prabowo's state visit from March 31 to April 2. The 16-jet first order is down from the 48 aircraft Indonesia originally planned to buy as a partner in the program.
Korea Aerospace Industries rolled out the first production KF-21 Boramae fighter at its Sacheon factory on March 25, 2026. The aircraft will undergo acceptance testing before delivery to the ROKAF in the second half of 2026.
Hanwha Aerospace and Korea Aerospace Industries (KAI) signed a joint development MOU for air-launched weapons at the WDS 2026, targeting long-range air-to-air missiles and supersonic air-to-surface missiles for the KF-21 Boramae and FA-50 platforms.
The KF-21 Boramae conducted its final test flight on January 12, 2026, concluding a flight test program spanning 1,600 sorties over 42 months. DAPA is set to finalize the development program in the first half of 2026.
Hanwha Systems rolled out the first mass-produced AESA radar for the KF-21 Boramae fighter at its Yongin R&D Center, featuring approximately 1,000 T/R modules. The radar is a critical indigenous component of Korea's 4.5-generation fighter.
At IndoDefense 2025, Indonesia and South Korea signed a new agreement reaffirming Indonesia's planned purchase of 48 KF-21 Boramae aircraft with PT Dirgantara Indonesia (PT DI) production participation, paving the way for the first KF-21 export.
DAPA held a ceremony marking the start of final assembly for the first mass-produced KF-21 Boramae at KAI's Sacheon facility. With prototype flight testing expected to continue until 2026, the milestone moves the program from development toward serial production.
The KF-21 Boramae has completed its full flight test program, including weapons integration tests with air-to-air missiles. The achievement clears the path for initial operational capability and serial production.
Korea Aerospace Industries has been awarded a 1.96 trillion won ($1.41 billion) contract to begin initial production of the KF-21 Boramae fighter. The first production batch covers 20 Block 1 aircraft for the Republic of Korea Air Force, with another 20 possibly ordered the following year.
Korea Aerospace Industries' KF-21 Boramae 4.5-generation fighter achieved its first supersonic flight, breaking Mach 1.0 during a test flight from Sacheon Air Base. The milestone brings Korea closer to indigenous advanced fighter production.
