Mil Mi-17

The Mil Mi‑17, a versatile medium‑lift transport helicopter, entered service in the early 1970s as an upgraded version of the legendary Mi‑8. Developed by the Mil Design Bureau and produced in large numbers by Kazan Helicopters, the Mi‑17 incorporates a more powerful turboshaft engine, an enlarged cabin, and improved avionics that allow operation in extreme climates from the Siberian tundra to desert hot zones. Its seven‑blade main rotor and twin‑engine configuration provide a maximum take‑off weight of roughly 13 t, enabling the carriage of up to 24 passengers, 4 000 kg of cargo, or a wide range of external loads such as fire‑suppression buckets and weapon systems. The helicopter’s robust airframe, redundant hydraulic systems, and full‑authorisation flight‑control suite have earned it a reputation for reliability and safety in both civilian and military roles. Over 12 000 units have been delivered to more than 50 countries, making the Mi‑17 one of the most widely exported rotorcraft in history. Its adaptability for transport, medevac, SAR, and armed‑escort missions has cemented its significance in modern aviation, where it continues to set standards for cost‑effective, multi‑mission capability today.
