The Mil Mi-24 is a large combat helicopter gunship and low-capacity troop transport operated from 1976 by the Soviet Air Force, its successors, and over thirty other nations.
Its NATO reporting name is Hind and variants are identified with an additional letter. The export versions, Mi-25 and Mi-35, are denoted as Hind D and Hind E respectively. Soviet pilots called the aircraft 'letayushiy tank' or flying tank. Another common nickname is 'Krokodil' (Crocodile) - due to the helicopter's camouflage and hull shape.
The core of the aircraft was taken from the Mil Mi-8 (NATO reporting name "Hip"), two top mounted turboshaft engines driving a mid-mounted 17.3 m five-blade main rotor and a three blade tail rotor. The engine positions give the aircraft its distinctive double air intake. Versions D and above include a characteristic tandem cockpit with a "double bubble" canopy. Other components of the airframe came from the Mi-14. Weapon hardpoints are provided by two short mid-mounted wings (which also provide lift), each offering three stations. The load-out mix is mission dependent; the Hind can be tasked with close air support, anti-tank operations, or aerial combat. The body is heavily armoured and the titanium rotor blades can resist impacts from 12.7 mm rounds. The cockpit is overpressurized to protect the crew in NBC conditions. The craft uses a retractable tricycle undercarriage.
Mi-24 (Hind-A) - Other early versions were the armed assault helicopter, which could carry eight combat troops and three crew members. It could also carry four 57-mm rocket pods on four underwing pylons, four 9M17 Falanga (AT-2 Swatter) anti-tank missiles on two underwing rails, free-fall bombs, plus one 12.7-mm machine-gun in the nose. The Mi-24 (Hind-A) was the first production model.
Mi-24D (Hind-D) - The most common variant, a purer gunship than the earlier variants, the first to include the electronics for Anti-tank guided missiles 9M17 Falanga (AT-2 Swatter). The Mi-24D has a redesigned forward fuselage, with two separate cockpits for the pilot and gunner. It is armed with a single 12.7-mm four-barrel machine-gun under the nose. It can carry four 57-mm rocket pods, four 9M17 Falanga (AT-2 Swatter) anti-tank missiles, plus bombs and other weapons.
