The broad-reaching Mil Mi-4 series of helicopter (known to NATO as "Hound") first appeared in 1952 and was designed within the Soviet Union as a direct response to the American H-19 Chickasaw helicopter debuting in the Korean conflict of the early 1950s. The system generally appeared much like the H-19 system but was seen as a more capable product when compared to the American product. In the end, the Mi-4 proved to be a highly adaptable and affordable transport system that could be used in an armed role and would see owners throughout all of Asia, the Middle East and Africa.

The Mi-4 was designed with a high-set cockpit that could accommodate one or two pilots. Passenger seating was provided on a lower deck with access via side doors. Structural piping could be added externally to hold rocket pods and gunpods as needed when in the armed role. Power was derived from a single Shvetsov ASh-82V radial engine delivering some 1,675 horsepower while driving a four-bladed main rotor and a three-bladed tail rotor.

The Hound appeared in a few variant forms that included both military and civilian transports, VIP transports and anti-ship platforms. The Mi-4 was used by no fewer than 30 countries and still maintains a limited role in some air forces today, though long since retired from Russian inventories. The Mi-4 served for a time with the Indian Army as its standard military transport.
