The worst of the “flying coffins.”
The MiG-23 was initially intended to fill out the air forces of the Warsaw Pact, but the Soviet clients generally preferred to keep their Fishbeds. Indeed, in export terms the MiG-23 was essentially a cheap loss-leader for the Soviet engine and technical support industries, as it proved remarkably difficult to safely keep in service. By design, engines burned out quickly, meaning that export customers who had fallen out of Soviet graces quickly lost the use of their fighters. The Flogger’s combat record, generally in Syrian, Iraqi, and Libyan service, has not been positive. It’s hardly surprising that the MiG-23 will almost certainly leave service before its predecessor, the MiG-21.
Over the last century of military aviation, several fighters have earned the nickname “flying coffin.” Military aviation inherently pushes up against the limits of technology and human endurance, particularly where fighter and pursuit aviation is concerned. Flying a fighter is remarkably dangerous, even when no one is trying to shoot you down.

Engineering a capable fighter plane is also a struggle. Relatively small changes in engine, armament, and airframe design can transform a clunker into an elite fighting machine; many of the best fighters in history were initially viewed askance by their pilots. But elite status rarely lasts for long, especially in World War I and World War II. Fighters that dominated the sky in one year become “flying coffins” as technology and tactics move forward.
