The WWS-2 Żaba (Frog) was a single-seat training glider designed and built in Poland from 1937.

Czerwiński improved the design of the CWJ-bis, with reduced structure weight and changes to the flying control surfaces, to improve performance and manoeuverability. The W.W.S. 2 followed the primary trainer concept with a skeletal fuselage wire-braced to a simple fabric covered wing, supported by two struts each side, and tail unit. The completely open seating area followed the theory of the day, that called for the student pilot to feel the wind on his/her body to fully appreciate the movements of the aircraft in response to control movements and atmospheric changes, such as gusts, turbulence or thermals. One W.W.S. 2 survived the war, to fly again, and was retired to the Krakow Aviation Museum in 1950.
Production of the Żaba at the W.W.S. Commenced in 1937, with 60-70 built before the outbreak of WWII. The Żaba II (Żaba-bis) was produced at the Lwow aviation workshops (L.W.L.), with approx 150 built, 20 for export.
