The answer, it turns out, is that the biplane wins more often than anyone would like to admit. During the Korean War, North Korean pilots flying Polikarpov Po-2 biplanes \u2014 fabric-covered, open-cockpit trainers designed in 1928 \u2014 conducted a campaign of nocturnal harassment that drove the United States Air Force to distraction. They destroyed aircraft worth millions of dollars, killed personnel, wrecked equipment, and even claimed the only biplane-versus-jet kill in aviation history.<\/p><div style=\"display:flex;justify-content:center;margin:2em 0\"><iframe class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/Qx4depB-_JQ\" title=\"The Only Biplane With A Jet Combat Kill (Sort of...) \u2013 Polikarpov Po-2\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen style=\"max-width:100%\"><\/iframe><\/div>\n\n<h2>The Ghost of 1928<\/h2><p>The Polikarpov Po-2 was not designed for combat. Created by Nikolai Polikarpov in 1928, it was a simple, rugged biplane trainer intended to teach basic flying skills. Built of plywood, fabric, and steel tubing, it had a top speed of about 94 miles per hour \u2014 slower than a modern automobile on a highway. Its range, payload, and instrumentation were minimal. Production estimates range from 20,000 to more than 30,000, making it one of the most produced aircraft in history.<\/p><p>The Po-2 had seen combat before Korea. During World War II, the Soviet Union famously used them as night bombers against the Germans, most notably in the all-female 588th Night Bomber Regiment \u2014 the legendary \"Night Witches.\" The Germans called the Po-2 the \"Sewing Machine\" for the distinctive sound of its five-cylinder Shvetsov M-11 engine. The tactic was always the same: fly low and slow in darkness, drop small bombs on enemy positions, and disappear before anyone could respond.<\/p><h2>Bedcheck Charlie Arrives<\/h2><p>In the spring of 1951, as United Nations forces pushed north and the air war over Korea intensified, North Korean Po-2s began appearing over UN airfields after dark. The raids followed a maddening pattern. Around midnight \u2014 just as exhausted ground crews and pilots were trying to sleep \u2014 the distinctive put-put-put of a Po-2 engine would be heard overhead. Then came the bombs.<\/p><p>The bombs were small \u2014 sometimes modified artillery shells or hand grenades dropped by the observer in the rear cockpit. But the effect was devastating out of all proportion to the ordnance involved. Aircraft parked on ramps were exposed and vulnerable. A single well-placed bomb could destroy or damage a jet fighter worth hundreds of thousands of dollars. Radar equipment, fuel dumps, and communications facilities were all targets.<\/p>\r\n<figure class=\"wp-block-image size-large\" style=\"margin:0 0 24px\"><img data-opt-id=1430811510  fetchpriority=\"high\" decoding=\"async\" class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" src=\"https:\/\/ml5psubhxdln.i.optimole.com\/cb:0e0_.b970\/w:auto\/h:auto\/q:mauto\/ig:avif\/https:\/\/migflug.com\/jetflights\/wp-content\/uploads\/sites\/4\/2026\/06\/f-86-sabre-korean-war-jet-fighter.jpg\" alt=\"North American F-86 Sabres \u2014 the most advanced US fighter in Korea, yet vulnerable on the ground to biplane attacks\" style=\"display:block;width:100%!important;max-width:100%!important;height:auto!important;border-radius:6px\"><figcaption style=\"font-size:13px;color:#777;text-align:center;margin-top:6px;font-style:italic\">The F-86 Sabre was designed to fight MiG-15s at 600 mph.

The biplanes destroyed one F-86 and damaged eight others, four of them seriously. The irony was excruciating: a plane that cost essentially nothing to build had destroyed aircraft that represented the cutting edge of American aerospace technology.<\/p><div style=\"display:flex;justify-content:center;margin:2em 0\"><blockquote class=\"reddit-embed-bq\" data-embed-height=\"500\"><a href=\"https:\/\/www.reddit.com\/r\/todayilearned\/comments\/5avzbu\/til_the_po2_is_the_only_biplane_with_a_documented\/\">TIL the PO-2 is the only biplane with a documented kill of a jet<\/a><\/blockquote><script async src=\"https:\/\/embed.reddit.com\/widgets.js\" charset=\"utf-8\"><\/script><\/div>\n\n<h2>Why Jets Could Not Stop Them<\/h2><p>The USAF response to Bedcheck Charlie was initially confident. They had jet fighters, radar, and overwhelming technical superiority. Surely stopping a 94-mph biplane would be trivial. It was not.<\/p><p>The problems were fundamental. First, the Po-2 was nearly invisible to radar. Its wood-and-fabric construction produced an almost negligible radar return. Ground-based radar could sometimes detect it, but airborne intercept radar \u2014 the kind carried by night fighters \u2014 struggled to distinguish it from ground clutter at low altitude.<\/p><p>Second, and more critically, the speed differential between the Po-2 and its pursuers was absurd. An F-86 Sabre had a top speed of 687 mph. The Po-2 flew at under 100 mph. A jet interceptor attempting to match the biplane had to slow to the ragged edge of its stall speed \u2014 and beyond. In February 1952, an F-94 Starfire night fighter was directed toward a Po-2 by ground radar. The pilot found the biplane and made three unsuccessful passes, unable to slow down enough to line up a shot without stalling his own aircraft.<\/p>\r\n<div style=\"background:#f4f4f4;border-left:4px solid #5C91FF;padding:16px 20px;margin:18px 0 28px;border-radius:0 8px 8px 0\"><p style=\"margin:0 0 8px;font-weight:700;color:#333;font-size:17px\">Quick Facts<\/p><ul style=\"margin:0;padding-left:18px\"><li style=\"margin:4px 0;color:#444\">Po-2 first flight,1928<\/li><li style=\"margin:4px 0;color:#444\">Po-2 top speed,152 km\/h (94 mph)<\/li><li style=\"margin:4px 0;color:#444\">F-86 Sabre top speed,1,106 km\/h (687 mph)<\/li><li style=\"margin:4px 0;color:#444\">Speed ratio,Jets were 7-10x faster than the Po-2<\/li><li style=\"margin:4px 0;color:#444\">Po-2 construction,Wood and fabric<\/li><li style=\"margin:4px 0;color:#444\">Radar signature,Virtually undetectable<\/li><li style=\"margin:4px 0;color:#444\">Jet kill credit,1 F-94 Starfire lost during intercept (stall)<\/li><li style=\"margin:4px 0;color:#444\">Ground kills,Multiple F-86s and other aircraft destroyed at airfields<\/li><\/ul><\/div>\r\n<p>On another occasion, an F-94 Starfire pilot slowed to 100 mph \u2014 well below the jet stall speed of approximately 120 mph \u2014 in an attempt to engage a Po-2. The Starfire stalled and crashed. The Po-2 was officially credited with the kill, making it the only biplane ever to claim a jet aircraft in combat. The jet, in effect, shot itself down trying to engage a target that was too slow to intercept.<\/p><h2>Adapting to the Threat<\/h2><p>The USAF eventually adapted, though never completely solved the problem. Propeller-driven aircraft \u2014 including F4U Corsairs flown by Marine night fighter pilots \u2014 proved more effective against the Po-2s because they could slow down enough to engage. Ground-based anti-aircraft defenses were improved. Blackout procedures were tightened. Aircraft dispersal and revetments were enhanced.<\/p><p>But the harassment never completely stopped. The Po-2s continued their raids throughout the war, exploiting the fact that the most technologically advanced air force in the world had no simple answer to the oldest and simplest tactical problem in aviation: how do you catch something that flies slower than you can go without falling out of the sky?<\/p><div style=\"display:flex;justify-content:center;margin:2em 0\"><blockquote class=\"twitter-tweet\"><a href=\"https:\/\/x.com\/OnDisasters\/status\/1990213765921427938\"><\/a><\/blockquote><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/div>\n\n<h2>The Lesson<\/h2><p>The Bedcheck Charlie campaign is one of the great asymmetric warfare stories in military aviation. A fleet of obsolete trainers costing practically nothing to build or operate forced the United States to divert significant resources \u2014 night fighters, radar stations, anti-aircraft batteries, alertness procedures \u2014 to counter a threat that should have been beneath notice. The Po-2 could not win the war. But it could ensure that the other side never had a quiet night, and in war, that counts for something.<\/p><p>The story also serves as a reminder that technological superiority does not automatically translate to tactical dominance. The same lesson would be relearned decades later with IEDs, drones, and other low-tech weapons that proved devastatingly effective against far more sophisticated adversaries. The 1928 Polikarpov Po-2, puttering through the Korean night sky at 94 miles per hour, was one of the earliest demonstrations of a principle that military planners still struggle with today.<\/p>\n\n<!-- mf-faq -->\n\n<div class=\"mf-faq-block\"><style>.mf-faq-block{margin:34px 0}.mf-faq-item:not([open]) .mf-faq-answer{display:none !important}.mf-faq-block h2.mf-faq-h{padding-top:22px;margin-bottom:14px}.mf-faq-item{border:1px solid #e2e8f5;border-radius:8px;margin:0 0 10px;background:#fff}.mf-faq-item summary{list-style:none;cursor:pointer;padding:15px 50px 15px 18px;font-weight:600;color:#1a1a1a;position:relative;line-height:1.45;user-select:none}.mf-faq-item summary::-webkit-details-marker{display:none}.mf-faq-item summary::after{content:\"+\";position:absolute;right:18px;top:50%;transform:translateY(-50%);font-size:1.5em;font-weight:400;color:#5C91FF;line-height:1}.mf-faq-item[open] summary::after{content:\"\\2013\"}.mf-faq-item[open] summary{border-bottom:1px solid #eef1f8}.mf-faq-item summary:hover{background:#f5f8ff}.mf-faq-answer{padding:14px 18px;color:#333;line-height:1.6}.mf-faq-answer p{margin:0}<\/style><h2 class=\"mf-faq-h\">Related Questions<\/h2><details class=\"mf-faq-item\"><summary>What was 'Bedcheck Charlie' in the Korean War?<\/summary><div class=\"mf-faq-answer\"><p>'Bedcheck Charlie' was the nickname for North Korean pilots who flew Polikarpov Po-2 biplanes on nocturnal harassment raids against UN airfields during the Korean War.
