The Mi-4 HOUND helicopter is a piston-engined aircraft developed for unarmed military transport. Approximately 3,000 Mi-4 Hounds were built before production ended in 1969. These piston-engined aircraft have been largely replaced by jet-powered helicopters in the transport and antisubmarine role. The large, four-blade main rotor is mounted on top of the fuselage midsection. The single piston engine is mounted within the nose section. The fuselage is short and oval with a solid rounded nose and stepped-up cockpit. It features a high-mounted, long, thin tail boom with a gun mount under the belly (oil pan) and four-wheeled landing gear. The tail is small, with a three-blade rotor attached to right side of the thin fin and small flats forward of the fin.
