Mikoyan-Gurevitch Izdeliye 33 (MiG-33 Foghorn acording ASSC-NATO nomeclature).
Around 1980, the Mikoyan OKB design bureau began working on a very light “strike fighter” that was intended to be a direct competitor to the F-16 Fighting Falcon. This new Mikoyan design, designated Izdeliye 33 (Izd 33) (and variously translated as “Article 33”, “Project 33”, “Product 33”, or “Project R-33”), was of conventional layout and similar in appearance to the F-16. It was powered by a single Klimov RD-33 afterburning turbofan engine – the same engine used by the twin-engined MiG-29. While extensive wind-tunnel testing was conducted on the design, no prototypes were built since the Soviet Air Force (VVS) dropped its support for concept about 1986. The program was one of several victims of the VVS’ changing operational needs, financial constraints, and a growing preference for twin-engined,multirole designs
