It was designed in 1984 by the Composite Structure Technology Team at the Faculty of Power and Aeronautical Engineering of the Warsaw University of Technology, consisting of: Dr. Eng. Roman Świtkiewicz, MSc. Eng. Krzysztof Drabarek, MSc. Eng. Jan Filipiak, MSc. Eng. Andrzej Gozdalik, MSc. Eng. Jerzy Kędzierski, MSc. Eng. Krzysztof Pierzchanowski, MSc. Eng.

Initially named ULS-Zestaw, it was later renamed PW-2 Gapa. It is a single-seat, strut-braced high-wing glider of composite construction. The prototype was first flown by January Roman on 25 July 1985 in Warsaw. Series production of the PW-2D version began a year later. A total of 19 units were produced, of which 6 were exported to the USA, 3 to Japan, 1 to Mexico and 2 to Colombia.
