On Wednesday 11 November, South Korea&rsquo;s most senior military officer climbed into one instead. Gen. Jin Yong-sung, Chairman of the Joint Chiefs of Staff, flew aboard a <a href=\"https:\/\/migflug.com\/aircraft\/kf-21-boramae\/\">KF-21 Boramae<\/a> over North Gyeongsang Province and led a formation of Korean-built fighters while he checked how ready the air defences really are.<\/p>\n\n<p>The flight took place during a visit to the <a href=\"https:\/\/migflug.com\/air-forces\/republic-of-korea-air-force\/\">Republic of Korea Air Force<\/a>&rsquo;s 16th Fighter Wing at Yecheon, about 160 kilometres southeast of Seoul. According to the Joint Chiefs of Staff, Jin commanded a formation flight that put the KF-21 alongside the FA-50, the light combat version of the <a href=\"https:\/\/migflug.com\/aircraft\/kai-t-50-golden-eagle\/\">KAI T-50 Golden Eagle<\/a>. Photographs released by the JCS and carried by Financial News show two KF-21s and two FA-50s flying together.<\/p>\n\n<p>Less than two months after the first production Boramae landed at Yecheon, the man at the top of the chain of command has now flown in one. It is a small moment, but it says a lot about where the programme stands.<\/p>\n\n\n<div style=\"background:#f4f6f9;border:1px solid #e2e7ee;padding:18px 22px;margin:22px 0 26px\"><p style=\"margin:0 0 8px;font-weight:700;color:#0d1117\">Quick Facts<\/p><ul style=\"margin:0;padding-left:18px\"><li style=\"margin:4px 0\"><strong>Who:<\/strong> Gen.

According to the Korea Times, he urged them to keep a posture and capability to deter the enemy through &ldquo;overwhelming&rdquo; air superiority and to be able to respond immediately to any contingency. KFN quoted the same instruction: be ready to scramble at once if a situation develops.<\/p>\n\n<p>Military Watch Magazine reported that the two KF-21s in the formation were among the first serial-production aircraft. That detail has not been spelled out in the Korean reports read for this article, but it fits the timeline: the 16th Fighter Wing is the home of the 156th Fighter Squadron, the unit reactivated in June to introduce the type.<\/p>\n\n\n<div style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin:24px 0 8px\"><iframe class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" src=\"https:\/\/www.youtube.com\/embed\/q6ZXuRVBj1Q\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0\" allowfullscreen><\/iframe><\/div>\n\n<p style=\"font-size:13px;color:#777;text-align:center;font-style:italic;margin:0 0 24px\">Korea Forces Network (KFN) report from 11 November 2026 on the JCS chairman&rsquo;s KF-21 command flight and his visit to a missile surveillance unit (in Korean).<\/p>\n\n<h2 style=\"padding-top:22px\">From the factory to the front line<\/h2>\n\n<p>The first production KF-21 flew from Korea Aerospace Industries&rsquo; plant at Sacheon to Yecheon on 22 September, as Afterburner reported at the time in <a href=\"https:\/\/migflug.com\/afterburner\/kf-21-boramae-first-production-delivery-rokaf-yecheon-2026\/\">KF-21 Boramae: South Korea Delivers Its First Production Fighter<\/a>. That aircraft went to the 156th Fighter Squadron. Seoul plans to buy 40 Block I aircraft by 2028 and 80 Block II aircraft through 2032, around 120 in all, to replace retired F-4 Phantoms and ageing F-5s.<\/p>\n\n<p>Financial News framed Wednesday&rsquo;s visit as a check on the KF-21&rsquo;s initial operational deployment. Block I aircraft carry their weapons externally and are weighted towards air-to-air work; the expanded strike capability comes with Block II.<\/p>\n\n\n<figure class=\"wp-block-image size-large\" style=\"margin:0 0 24px;width:100%\"><img decoding=\"async\" class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" width=\"1024\" src=\"https:\/\/migflug.com\/afterburner\/wp-content\/uploads\/sites\/4\/2026\/11\/rokaf-fa-50-formation-flares-cheonan-2015.jpg\" alt=\"A formation of Republic of Korea Air Force FA-50 light fighters releasing flares over the Independence Hall of Korea in Cheonan\" style=\"width:100%;height:auto;max-width:100%;display:block\"><figcaption style=\"font-size:13px;color:#777;text-align:center;margin-top:6px;font-style:italic\">Republic of Korea Air Force FA-50s release flares over the Independence Hall of Korea in Cheonan in February 2015.

That is the magazine&rsquo;s analysis rather than a stated Korean plan for this unit, but the two-seat version has been part of the programme since the prototype stage, and the first production airframe delivered to Yecheon was a two-seater.<\/p>\n\n<h2 style=\"padding-top:22px\">Watching for missiles<\/h2>\n\n<p>The fighter flight was only half of Jin&rsquo;s day. He also visited an air force unit responsible for detecting ballistic missile launches and checked the real-time readiness of the Korea Air and Missile Defense system, known as KAMD. The Korea Times reported that he called it a &ldquo;core asset&rdquo; of South Korea&rsquo;s three-axis deterrence system.<\/p>\n\n\n<div style=\"background:#f8f9fa;border-left:4px solid #1565c0;padding:20px 22px;margin:18px 0 24px;font-size:16px;line-height:1.7\"><div><em>&ldquo;This is the very unit that detects enemy missile provocations firsthand, marking the beginning of missile defense operations.&rdquo;<\/em><div style=\"margin-top:10px;font-size:14px;color:#555\"><strong>Gen.

The other two pillars of the three-axis system are the Kill Chain pre-emptive strike system and Korea Massive Punishment and Retaliation, the plan to incapacitate North Korea&rsquo;s leadership in a major conflict. Jin ordered the unit to maintain an around-the-clock early warning posture so that any type of missile is detected swiftly.<\/p>\n\n\n<figure class=\"wp-block-image size-large\" style=\"margin:0 0 24px;width:100%\"><img decoding=\"async\" class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" width=\"1024\" src=\"https:\/\/migflug.com\/afterburner\/wp-content\/uploads\/sites\/4\/2026\/11\/kf-21-boramae-prototype-006-flight.jpg\" alt=\"KF-21 Boramae prototype 006 banking above the clouds\" style=\"width:100%;height:auto;max-width:100%;display:block\"><figcaption style=\"font-size:13px;color:#777;text-align:center;margin-top:6px;font-style:italic\">KF-21 prototype 006 in flight during the test programme, which ended before production aircraft began reaching the 16th Fighter Wing at Yecheon in September 2026.

When the chairman of the Joint Chiefs straps into a home-grown fighter in front of the cameras, he is telling his own forces, the defence industry and potential export customers that the jet is ready to be trusted.<\/p>\n\n<p>For the KF-21, that message lands at a useful moment. The first squadron is still converting pilots and maintainers, and a delivered fighter is not yet a combat-ready unit. But a 25-year effort to build a Korean fighter has now reached the point where the country&rsquo;s top officer goes flying in one to inspect the air defence of the country.<\/p>\n\n\n\n<p><em>Sources: Korea Times, Financial News (fnnews), KFN Korea Forces Network, Military Watch Magazine, Republic of Korea Joint Chiefs of Staff<\/em><\/p>\n<!-- mfsh:bottom -->\n\n<button type=\"button\" class=\"mfsh-trigger mfsh-bottom\" data-mfsh-placement=\"bottom\" aria-haspopup=\"dialog\"><svg><use href=\"#mfsh-i-share\"\/><\/svg>Share this story<\/button>\n\n<!-- \/mfsh:bottom -->\n\n<p class=\"mf-photo-credits\" data-no-translation style=\"font-size:13px;color:#777;font-style:italic;margin:6px 0 18px\">Header photo: <a href=\"https:\/\/commons.wikimedia.org\/wiki\/File:KF-21_prototype_003_and_004_during_flight_testing.jpg\" target=\"_blank\" rel=\"noopener\">Defense Acquisition Program Administration (DAPA) \/ Wikimedia Commons, KOGL Type 1<\/a><\/p>\n\n\n<style>.mfq{margin:34px 0 8px}.mfq h2{font:26px\/1.3 \"Gilroy semiBold\",Helvetica,Arial,sans-serif;color:#0d1117;padding-top:22px;margin:0 0 6px}.mfq .qa details{border-top:1px solid #5C91FF;margin:0;padding:0}.mfq .qa details:last-of-type{border-bottom:1px solid #e2e7ee}.mfq .qa summary{cursor:pointer;list-style:none;display:flex;justify-content:space-between;align-items:center;gap:16px;padding:22px 26px;font:18px\/1.7 \"Gilroy semiBold\",Helvetica,Arial,sans-serif;color:#0d1117}.mfq .qa summary::-webkit-details-marker{display:none}.mfq .qa summary::after{content:\"+\";font:24px Helvetica,sans-serif;color:#3568e0;flex:0 0 auto}.mfq .qa details[open] summary::after{content:\"\\2013\"}.mfq .qa details:hover summary{color:#3568e0}.mfq .qa .a{font:16px\/1.7 \"Gilroy regular\",Helvetica,Arial,sans-serif;color:#454e5e;padding:0 26px 24px}.mfq .qa .a a{color:#3568e0}@media(max-width:680px){.mfq .qa summary{padding:18px 14px;font-size:17px}.mfq .qa .a{padding:0 14px 20px}}<\/style>\n\n\n<section class=\"mfq\"><h2>Frequently Asked Questions<\/h2><div class=\"qa\"><details open><summary>Who flew in the KF-21 Boramae on 11 November 2026?<\/summary><div class=\"a\">Gen.
