As with the Messerschmitt Bf 109 piston-engined fighter, the Messerschmitt Me 262 "Schwalbe" jet-powered fighter's production was also charged to Czechoslovakian factories in the latter stages of World War 2 (1939-1945). When the war in Europe ended against Germany's favor in May of 1945, Czechoslovakia still found itself in possession of the equipment required to build both aircraft. These were then rebranded by Avia under the respective designations of S-99/S-199 (based on the Bf 109G) and S-92 "Turbina" (based on the Me 262A).
In the latter case, the Czechs took to producing both the single- and two-seat variants of the German jet fighter as the "S-92" and "CS-92". The S-92 marked the primary fighter form while CS-92 represented two-seat trainer platforms. In 1946, twelve (nine single-seaters and three twin-seaters) were produced for testing and service introduction was announced the following year.
Prototype S-92.1 went airborne for the first time on August 27th, 1946 but an accident claimed this airframe that September. The second prototype, S-92.2, first flew on October 24th, 1946. The two-seat trainer variant saw its first-flight on December 10th, 1946. Another prototype, S-92.7, was outfitted with the uprated BMW 003 series turbojet engine but tests did not prove this offering quite as sound as had been hoped despite the increase to total thrust.
In 1950, the first Czechoslovakian fighter squadron comprised solely of jet fighter aircraft was finally formed but these mounts were kept for only a short time as Soviet jet-powered designs of greater performance and capabilities became available in large supply. After a formal demonstration to Yugoslav authorities, Yugoslavia placed an order for two S-92 jet fighters but this was never fulfilled.
In practice, the Czech S-92 performance about as well as the wartime Me 262 but, by the early 1950s, were entirely outclassed by the new crop of fighters emerging from the Soviet Union and in the West. This accounts for the relatively short operational service lives of the Turbina and its low production total. Outwardly, the fighters were faithful to the German design that appeared in April of 1944 and shocked many onlookers.

Design utilizes a single primary wing mainplane; this represents the most popular modern mainplane arrangement.
Mainplanes are low-mounted along the sides of the fuselage.
The planform features wing sweep back along the leading edges of the mainplane, promoting higher operating speeds.
