The aircraft was designed in response to a Polish Air Force requirement of 1946 for a trainer plane to replace the Soviet UT-2s, which were obsolete and difficult to handle aircraft. The new plane was designed in 1947 in the LWD (Lotnicze Warsztaty Doswiadczalne - Experimental Aviation Workshops) - the first Polish post-war construction team. The main designer was Tadeusz Soltyk . A prototype named LWD Junak, then Junak 1 was flown on February 22, 1948. A whole design was Polish, except for an engine, which was licence-built Soviet Shvetsov M-11D (93 kW, 125 hp). After tests, an improved variant Junak 2 was flown in 1949 and put to a production in 1951. The most notable changes from the Junak 1 were: crew cab moved towards front, bigger tail and stronger M-11FR engine (118 kW, 160 hp). In a meantime, the LWD was disbanded in 1949 and the Junak 2 was further developed by the CSS workshops in Warsaw. From 1951 to 1954, 105 Junak 2s were produced in the WSK-4 Okecie in Warsaw.
After the Polish Air Force was equipped with its first jet fighters ( Yak-23 , MiG-15), there appeared a need of a trainer plane with a tricycle landing gear. Tadeusz Soltyk, working in the IL (Aviation Institute) proposed an improved Junak with bubble canopy and retractable landing gear, that was to be designated TS-7 Chwat, but it was not accepted by the authorities and remained in sketches. Then, Soltyk designed a modified Junak with a fixed tricycle landing gear and minor improvements. This plane was accepted for a production as TS-9 Junak 3 ("TS" for Tadeusz Soltyk). It was flown on August 7August 7 is the 219th day of the year in the Gregorian Calendar (220th in leap years), with 146 days remaining.

Along with the Junak 1, the LWD developed its civilian trainer-aerobatic variant LWD Zuch 1 with Walter Minor 6 -III inline engine (119 kW, 160 hp), flown in 1948, then the LWD Zuch 2 with the Bramo Sh 14 (116 hp) radial engine. Only a short series of 5 Zuch 2s was built in 1950 and used until 1955.
Junak 2s were used in the Polish military trainer aviation from 1952. When their replacement with Junak 3s started in 1954-55, Junak 2s were withdrawn and given to civilian aviation. Junak 3s were used in the Polish military trainer aviation from 1954 until 1961, when they were finally replaced with TS-8 Bies. Starting from 1956, they were given to civilian aviation as well.
In the civilian aviation, 71 Junak 2s and 93 Junak 3s were distributed among aeroclubs in the country, suffering lack of aircraft.

The Junak was the first aircraft built in a big series in Poland after the World War IIWorld War II was the most extensive and costly armed conflict in the history of the world, involving the great majority of the world's nations, being fought simultaneously in several major theatres, and costing tens of millions of lives. The war was fough, which anihilated the Polish aviation industry. Despite not very modern, it was a stable and good handling aircraft, one of its few flaws was uncomfortable cab. All models of Junak are often called LWD Junak or WSK Junak, a designation TS-9 is not commonly used.
