The SZD-15 Sroka is a training glider of wooden construction, a successor to the pre-war Komar glider, designed in 1955 on order from the League of Friends of the Soldier, which at that time oversaw sport aviation.
It was intended to succeed the IS-B “Komar” glider, but the requirements specified in the order did not represent an improvement over its predecessor. The chief designer was Eng. Zbigniew Badura. The prototype was first flown in February 1956, and serial production began in 1957 at the Sports Aviation Equipment Works No. 5 in Krosno.
The Sroka glider did not have a successful career, as it was already outdated at the time of its creation and was poorly suited for training. 20 examples were produced and distributed among aero clubs, where they were used for practice. The last examples were used until the mid-1970s.
The exhibited example, serial number 299, SP-1726, was operated from 1957 to 1976 by the Bielsko-Biala Aero Club. It completed 326 flights totalling 1,362 hours.
