The aircraft meant to fix that &mdash; the Heinkel He 177 Greif &mdash; had four engines but only two propellers, a quirk that made it burst into flames so often the crews called it the <em>Reichsfeuerzeug<\/em>: the Reich&rsquo;s cigarette lighter.<\/p>\r\n<p class=\"wp-block-paragraph\">It is one of the great self-inflicted wounds of wartime aviation &mdash; a capable airframe ruined by a single stubborn requirement.<\/p>\r\n\r\n<div style=\"background:#f5f5f5;padding:20px;margin:24px 0;border-radius:6px\"><p style=\"margin:0 0 10px;font-weight:700;font-size:17px\">Informazioni rapide<\/p><table style=\"width:100%;border-collapse:collapse;font-size:15px\"><tr><td style=\"padding:4px 12px 4px 0;color:#555;vertical-align:top;white-space:nowrap\"><strong>Aeromobili<\/strong><\/td><td style=\"padding:4px 0\">Heinkel He 177 Greif (&ldquo;Griffin&rdquo;)<\/td><\/tr><tr><td style=\"padding:4px 12px 4px 0;color:#555;vertical-align:top;white-space:nowrap\"><strong>Ruolo<\/strong><\/td><td style=\"padding:4px 0\">Long-range heavy bomber<\/td><\/tr><tr><td style=\"padding:4px 12px 4px 0;color:#555;vertical-align:top;white-space:nowrap\"><strong>Primo volo<\/strong><\/td><td style=\"padding:4px 0\">November 1939 (He 177 V1)<\/td><\/tr><tr><td style=\"padding:4px 12px 4px 0;color:#555;vertical-align:top;white-space:nowrap\"><strong>Equipaggio<\/strong><\/td><td style=\"padding:4px 0\">Six<\/td><\/tr><tr><td style=\"padding:4px 12px 4px 0;color:#555;vertical-align:top;white-space:nowrap\"><strong>Motori<\/strong><\/td><td style=\"padding:4px 0\">Four, coupled in two pairs driving two propellers<\/td><\/tr><tr><td style=\"padding:4px 12px 4px 0;color:#555;vertical-align:top;white-space:nowrap\"><strong>Powerplants<\/strong><\/td><td style=\"padding:4px 0\">2 &times; Daimler-Benz DB 606, later DB 610<\/td><\/tr><tr><td style=\"padding:4px 12px 4px 0;color:#555;vertical-align:top;white-space:nowrap\"><strong>Costruito<\/strong><\/td><td style=\"padding:4px 0\">Roughly 1,100&ndash;1,170<\/td><\/tr><tr><td style=\"padding:4px 12px 4px 0;color:#555;vertical-align:top;white-space:nowrap\"><strong>Soprannome<\/strong><\/td><td style=\"padding:4px 0\">Reichsfeuerzeug &mdash; &ldquo;the Reich&rsquo;s lighter&rdquo;<\/td><\/tr><\/table><\/div>\r\n<h2 style=\"padding-top:22px\">Four engines, two propellers<\/h2>\r\n<p class=\"wp-block-paragraph\">The engineering at the heart of the He 177 is the key to the whole story. To keep drag low, Heinkel did not hang four separate engines under the wings. Instead it bolted pairs of Daimler-Benz inverted-V12 engines together, side by side, each pair geared to a single propeller. So the He 177 had four engines but only two nacelles and two props &mdash; it looked like a twin, and flew like a very troubled one.<\/p>\r\n<p class=\"wp-block-paragraph\">Cramming two hot engines into one tight nacelle, with oil and fuel lines running past red-hot exhaust manifolds, produced exactly what you would expect. Leaks dripped onto hot metal and caught fire. Six of the first eight prototypes were lost, most of them to engine fires.<\/p>\r\n\r\n<figure class=\"wp-block-image size-large\" style=\"margin:0 0 24px;width:100%\"><img data-opt-id=579575019  fetchpriority=\"high\" decoding=\"async\" class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" width=\"1024\" src=\"https:\/\/ml5psubhxdln.i.optimole.com\/cb:X_Jn.cfed\/w:auto\/h:auto\/q:mauto\/ig:avif\/https:\/\/migflug.com\/afterburner\/wp-content\/uploads\/sites\/4\/2026\/08\/heinkel-he-177-a5-fassberg.jpg\" alt=\"Captured He 177 A-5 at Fassberg 1945\" style=\"width:100%;height:auto;max-width:100%;display:block;border-radius:6px\"><figcaption style=\"font-size:13px;color:#777;text-align:center;margin-top:6px;font-style:italic\">A captured He 177 A-5 at Fassberg in 1945.

Coupling the engines was meant to keep the airframe clean and strong enough for diving. Ernst Udet championed the idea; Heinkel&rsquo;s pleas to simply use four separate engines were refused.<\/p>\r\n\r\n<div style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin:24px 0\"><iframe class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" src=\"https:\/\/www.youtube.com\/embed\/7Kv1CUjqtzE\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0;border-radius:8px\" allowfullscreen><\/iframe><\/div>\r\n<h2 style=\"padding-top:22px\">Even Hitler and G&ouml;ring gave up on it<\/h2>\r\n<p class=\"wp-block-paragraph\">The fury inside the German high command was extraordinary.

It flew raids on England where crews aborted with overheating engines, hauled supplies on the Eastern Front, and was thrown into the doomed effort to keep Stalingrad alive. A version with four separate engines, the He 177B, finally flew in 1944 &mdash; long after German bomber production had been all but abandoned.<\/p>\r\n<p class=\"wp-block-paragraph\">The tragedy of the He 177 is that the airframe was sound. Freed of the dive-bomber requirement and given four honest engines from the start, it might have been Germany&rsquo;s Lancaster. Instead it became a cautionary tale about what happens when a single specification is allowed to set a whole aircraft on fire.<\/p>\r\n\r\n<div style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin:24px 0\"><iframe class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" src=\"https:\/\/www.youtube.com\/embed\/5IjY7kIShEA\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0;border-radius:8px\" allowfullscreen><\/iframe><\/div>\r\n\r\n<div style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin:24px 0\"><iframe class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" src=\"https:\/\/www.youtube.com\/embed\/ii9FrFS5olc\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0;border-radius:8px\" allowfullscreen><\/iframe><\/div>\r\n<p class=\"wp-block-paragraph\"><em>Sources: Defense Media Network; Wikipedia; Bundesarchiv.<\/em><\/p>\r\n\r\n<div style=\"background:#f0f4ff;border-left:4px solid #5C91FF;padding:16px 20px;margin:32px 0 8px;border-radius:0 8px 8px 0\"><p style=\"margin:0 0 8px;font-weight:600;color:#333\">Post correlati<\/p><p style=\"margin:4px 0\"><a href=\"https:\/\/migflug.com\/afterburner\/it\/heinkel-he-219-uhu-night-fighter-ejection-seats\/\">Heinkel He 219 Uhu: il caccia notturno che la Germania si rifiut\u00f2 di costruire<\/a><\/p><p style=\"margin:4px 0\"><a href=\"https:\/\/migflug.com\/afterburner\/it\/lippisch-p13a-coal-ramjet-delta-interceptor\/\">Il caccia nazista progettato per bruciare carbone<\/a><\/p><\/div>","protected":false},"excerpt":{"rendered":"<p>Germany went into the Second World War without a modern four-engine heavy bomber, and it spent much of the war failing to build one.
