A SIMPLY DESIGNED AIRCRAFT, the U-2 (later dubbed the Po-2) Night Stalker proved to be one of the most versatile planes of the war. Although it was built as a civil and military trainer, the Soviets used it for supply, transport, liaison, medical evacuation, reconnaissance, and bombing duties. Starting in 1942 Polikarpov fitted the U-2 with underwing bomb racks for use as a night bomber—its most well-known role. When targeting bivouacked enemy troops, U-2 pilots often flew “low and slow,” approaching at treetop level before throttling back and gliding in over their targets. The abrupt attacks had a marked psychological impact on German soldiers resting well behind the lines; many units felt compelled to stay on guard through the night. The Soviet 588th Night Bomber Regiment, an all-woman squadron, famously used their U-2s to great effect on nocturnal harassment raids against the German rear. —Paraag Shukla
