flew harassment and precision bombing missions against the German military from 1942 until the end of the Second World War (1945). At its largest, it had 40 two-person crews. The regiment flew over 23,000 sorties, dropping over 3,000 tons of bombs and 26,000 incendiary shells. It was the most highly decorated female unit in the Soviet Air Force, with many pilots having flown over 800 missions by the end of the war, and twenty-three having been awarded the Hero of the Soviet Union title. Thirty-two of its members died during the war. The regiment flew in wood-and-canvas Polikarpov U-2 biplanes, a 1928 design intended for use as training aircraft (hence its original uchebnyy designation prefix of "U-") and for crop dusting, which also had a special U-2LNB version for the sort of night harassment attack missions flown by the 588th. The plane could only carry of bombs, so eight or more missions per night were often necessary. Although the aircraft was obsolete and slow, the pilots took advantage of its exceptional maneuverability; it also had a maximum speed that was lower than the stalling speed of both the Messerschmitt Bf 109 and the Focke-Wulf Fw 190, which made it very difficult for German pilots to shoot down, with the exception of fighter ace Josef Kociok, who grounded the regiment for an entire night by shooting down three or four of their planes on the night of 31 July 1 August 1943. Original reception Initially, this all-female aviation regiment was not welcomed into the military with open arms. Many of their male counterparts saw them as inferior and treated them with lack of respect. The women of the regiment were also given hand-me-downs of uniforms and over-sized shoes by the men, as well as rudimentary tools (such as rulers, flashlights and pencils) that lacked the "luxury" that the male soldiers received with their tools (for example, radar, guns and radios). Timeline and operations Members of the regiment were deployed from the Engels Military Aviation School to the Southern Front as part of the 218th Division of the 4th Air Army on 23 May 1942, where they arrived on 27 May. 12 June 1942: The regiment's baptism by fire took place on the Southern front in bombings of river crossings on the Mius, Severny Donets, and Don rivers as well as roads in the Sal steppes and Stavropol suburbs.
