The Kholshchevnikov VRDK (Vozdushno-Reaktivniy Dopolnitelniy Kompressor) (Russian: "Jet-Propelled Auxiliary Compressor”), or E-3020, was a motorjet developed in the Soviet Union during World War II. The VRDK was designed to give fighter aircraft a ten-minute performance boost during combat.

VRDK boosters were built in small numbers for use in the Mikoyan-Gurevich I-250 and Sukhoi Su-5 mixed propulsion fighter aircraft. Both aircraft made their first flights in 1945, shortly before the end of World War II.

Interest in VRDK technology declined quickly after World War II as Soviet designers focused on the development of turbojet powered fighter aircraft.
