The Czapla (Heron) was a tandem two-seat training glider, with a strut- supported, forward-swept, high-set wing and a welded steel tube fuselage with fabric covering. Design of the Czapla commenced in 1952 to the order of the Soldier's Friends' League paramilitary organization, to enable aeroclubs to train glider pilots in a two-seat trainee/instructor system. Main designers were Roman Zatwarnicki, Irena Kaniewska and Marian Gracz. The Czapla was designed to be launched by bungee, winch or aero-tow, and the prototype first flew on 23 November 1953, demonstrating the need for several improvements, which were introduced in the second prototype (flown on 26 March 1954) and the production model SZD-10bis Czapla.

A total of 157 were built.
