The Mi-171Sh helicopter is being produced by the Ulan-Ude Aviation Plant (UUAP), part of Russian Helicopters. It is a military transport variant of the Mi-171 helicopter. More than 120 helicopters were delivered to customers in the Middle East, South East Asia, Africa and Eastern Europe.
The military transport helicopter was introduced into the world market in 2002. The helicopter is delivered through the Russian state-owned special exporter Rosoboronexport.
The Mi-171Sh is deployed in a range of missions, including the airlift of assault forces, transportation of cargoes, troop fire support, air-to-surface attack, escort of the military columns, medical evacuation and combat search and rescue (CSAR) operations.
Mi-171Sh orders and deliveries
The Mi-171Sh helicopters have been ordered by Russian allied partners, as well as Nato members. UUAP delivered 26 Mi-171Sh helicopters to Croatia and the Czech Republic between 2005 and 2008.
In 2009, the Russian Ministry of Defence ordered the Mi-171Sh as part of the Russian Armed Forces modernisation programme. UUAP delivered the first batch of ten Mi-171AMTSh (Russian designation of Mi-171Sh) helicopters in December 2010. The second batch of helicopters was delivered in June 2011.
The Peruvian Ministry of Defence placed an order for six Mi-171Sh helicopters in 2010. Three helicopters were delivered in May 2011. Deliveries were concluded in September of the same year.
The helicopters will enter service with the Peruvian Army and Air Force.

The Mi-171Sh was specifically designed for operation in combat missions in local armed conflicts. The design incorporates a five-bladed main rotor, a tail rotor and non-retractable tricycle nose-wheel landing gear.
The glassed-in cockpit accommodates three crew and cabin houses up to 36 troops, or up to 12 casualties on stretchers. The helicopters are equipped with modern avionics and instrumental equipment to operate in all weather conditions at any time of the day.
The armour protection provided over crew cabin and vital units increases the combat survivability of the helicopter. The engine exhaust ducts are equipped with infrared suppression exhaust mixer boxes for a low infrared signature.
The helicopter has an IR-decoy dispensing system to counter an infrared homing surface-to-air missile or air-to-air missile. The fuel tank self-sealing covers and polyurethane foam protection avoid fuel explosion and leakage in case of combat damage.
The Mi-171Sh is armed with a Shturm-V high-precision guided missile system. The missiles can destroy modern battle tanks protected by explosive reactive armour, fortified points and aerial targets.
The Shturm-V missile complex launches Ataka supersonic missiles equipped with a hollow-charge warhead for defeating armoured targets. The missile can destroy aerial targets by a fragmentation warhead and lightly armoured combat materiel by using a high-explosive warhead.
The Mi-171Sh is also provided with hardpoints to carry up to 80 S-8 unguided rockets and GSh-23L 23mm cannons with an ammunition load of 500 rounds.
Small arms, such as the 7.62mm PKT machine gun, PK machine gun and RPK light machine gun, are mounted in the nose and rear fuselage sections. The gun pivots provided at the doorway and near the windows allow the onboard troops to operate these weapons during flight.
Mi-171Sh cargo systems and engines
The multifunctional cargo cabin has a length of 5.34m, width of 2.34m and a height of 1.8m. It provides enough internal space to carry 4,000kg of payload.
The helicopter can transport up to 4,000kg of cargo externally under sling. The main cabin features internal winch facilities, while the floor has tie-down rings for cargo transport. Either side of the fuselage is provided with a pod for an external fuel tank.
The Mi-171Sh is powered by two Klimov TV3-117VM turboshaft engines mounted on top of the fuselage. Each engine is rated at 1,641kW. The helicopter can be optionally fitted with two VK-2500 turboshaft engines, each rated at 2,700hp.
The Mi-171Sh can fly at a maximum altitude of 6,000m. The maximum speed of the helicopter is 250km/h. The range (without auxiliary fuel tanks) is 580km.
The helicopter has a maximum take-off weight of 13,000kg.
