First flown in 1947, the prototype was based on the German Ta-183 untested jet fighter design. The engine was a reworked version of the Rolls-Royce Nene which had somewhat rashly been given to the Russians at the end of WW2. 8,000 of these fast and agile fighters were produced in only 5 years and many were exported around the globe. The '15 is best known for its service in Korea where it put up formidable opposition to the American F-86's.
