Mil Mi-17

Key Specifications

Overview

The Mil Mi-17 is a Soviet-era medium-lift transport helicopter that first flew in 1975 and remains in widespread service globally. Derived from the earlier Mi-8, the Mi-17 features improved Klimov TV3-117MT turboshaft engines mounted higher on the fuselage, providing superior hot-and-high performance and better altitude capability. The helicopter is renowned for its ruggedness, reliability, and ability to operate from unprepared landing zones in challenging environments. With capacity for 24-34 passengers or equivalent cargo, it serves military transport, civilian passenger operations, medical evacuation, and search-and-rescue missions. The Mi-17 is operated by over 50 countries, including military forces and civilian operators across Eastern Europe, Asia, Africa, and Latin America. Its simple, proven design makes it exceptionally maintainable with minimal support infrastructure—a key advantage in remote regions. The aircraft features a large rear cargo ramp door, allowing rapid loading of troops or freight. Modern variants include avionics upgrades and enhanced glass cockpits. Despite its age design, the Mi-17 remains competitive in emerging markets due to its low acquisition cost, operational economy, and demonstrated reliability across diverse climates and terrain.
