The Letov Š-20 was a fighter aircraft produced in Czechoslovakia during the 1920s. It was a conventional single-bay biplane with unstaggered wings braced by N-struts. In overall appearance it greatly resembled contemporary SPAD fighters. The fuselage and empennage were of welded steel tube construction and covered in fabric. The wings had a tubular metal spar but were otherwise wooden and also fabric-skinned.
