The aircraft was designed in 1949 n the LWD (Lotnicze Warsztaty Doświadczalne - Aircraft Experimental Workshops) as a utility and liaison aircraft for the Polish Air Force. The chief designer was Tadeusz Sołtyk. It was the last LWD design. A prototype first flew on 16 May 1951 (pilot Antoni Szymański). Because of lack of more powerful engines, it was fitted with the only available license-built Soviet radial Shvetsov M-11FR (118 kW, 160 hp). In addition to increased airframe weight (it was 160 kg heavier, than expected), the engine appeared too weak. To obtain STOL capabilities, wings had slats and flaps. The wings were thinner near canopy to obtain good view, and they were slightly swept towards forward. Despite advantages, like short takeoff and landing and low stall speed, the performance was poor and the plane was not ordered for production. It was considered to use stronger WN-3 or Ivchenko AI-14 engines, but the design was abandoned, because Poland had bought a license to produce Yakovlev Yak-12M. Unusual feature was triple tail, with two small vertical stabilizers in addition to a main central one. It was meant to improve aircraft stability on high edges of attack.

The prototype was painted in Polish Air Force colours and markings, but was not used by the Polish Air Force. In 1951 it was passed to the Aviation Institute (Instytut Lotnictwa) to obtain certification of approval, and next it was used there for a couple of years. In 1952 it was given a civilian registration SP-GLB. The prototype was withdrawn from use in 1960 and in 1963 given to the Polish Aviation Museum in Kraków, where it remains in a damaged condition.
