• The origin story: how the Z-137 evolved from the Čmelák “Bumblebee,” a workhorse of Eastern Bloc collective farms. • The transformation: paint job, invasion stripes, and missiles that were once meant for MiG dogfights now mounted on a plane that normally dusts sunflowers. • The weapon itself: the R-73 missile, 18-mile range, high-off-boresight seeker, still deadly decades later. • The doctrine: why Ukraine bolts weapons onto anything: trucks, boats, drones, and now farm planes… to stretch every last bit of combat power from its arsenal. • The tactics: how a crop duster with no radar or sensors could still plug into Ukraine’s drone-hunting network, making it a flying shotgun for ambushes.
