The Mikoyan-Gurevich I-250, aka MiG-13, was a Soviet fighter aircraft developed as part of a crash program in 1944 to develop a high-performance fighter to counter German turbojet-powered aircraft such as the Messerschmitt Me 262.
The Mikoyan-Gurevich design bureau decided to focus on a design that used something more mature than the jet engine, which was still at an experimental stage in the Soviet Union, and chose a mixed-power solution with the Vozdushno-Reaktivny Dvigatel Kompressornyi – air reaction compressor jet motor-jet powered by the Klimov VK-107 V12 engine.
While quite successful when it worked, with a maximum speed of 820 km/h (510 mph) being reached during trials, production problems with the VRDK fatally delayed the program and it was cancelled in 1948 as obsolete.
