This is a single seater, all wooden glider built in the high wing strutter configuration. The design was carried out by engineer Tadeusz Grudziński who received the first price in the glider design competition issued in 1955 by the Friends of Soldiers League. Basing on the winning design, at the SZD Works in Bielsko-Biała technical documentation of the glider designated the SZD-18 Czajka (pewit) was prepared by engineer Władysław Okarmus. The prototype flew for the first time in November 1956 but the in-flight tests continued until spring 1957. It wasn't the first glider bearing the name "Czajka": before the Second World War, Antoni Kocjan designed Czajka I and Czajka II training gliders.

Meanwhile, Polish aero clubs became independent from the Friends of Soldiers League and the new training concept of using two seater gliders gained prominence. Therefore, though the Czajka appeared to be an excellent design in its class, superior to the ABC glider, it never entered into the series production.

The sole example was flown for a few years at the Warsaw Aero Club, and was subsequently donated to the Museum's collection.
