MiG-13/I-250/N A.I.Mikoyan/M.I.Gurevich

(B/W, 41k) From Ned Avejic collection;

A small all-metal mixed-power fighter with a piston engine in the nose and a VRDK 'booster' in the tail. VRDK was basically a jet engine with a compressor driven by the V.Ya.Klimov engine. It had variable exhaust nozzle. Joined power of both engines was up to 2800hp (at 7000m).

It was very well armed - 3 B-20 cannons provided salvo of 3.84kg/sec. One of cannons was installed to fire through the spinner, two others - on the engine sides, synchronized.
