Based on a fuselage of the SZD-8 Jaskółka, the SZD-11 Albatros was designed to investigate the performance of aircraft during flight in thermal lift. Main designer was Justyn Sandauer, main constructor was J. Niespał. With wings of greater span, and reduced empty weight, the wing loading was reduced which markedly improved the climb performance over the 16m-span SZD-8 Jaskółka. Three more SZD-11 aircraft were planned with fixed trailing edges and no flaps, but only the prototype was completed. The SZD-11 first flew on 14 September 1954, flown by Tadeusz Góra.
