64-515: The Sikorsky H-60 is a family of military helicopters built by Sikorsky Aircraft . All models use a modified mission symbol in addition to the 'H' vehicle type designator under the 1962 United States Tri-Service aircraft designation system (meaning, there is no aircraft named an "H-60" per se). The mission prefix (e.g. U, M, V) only has tangential meaning to the suffix series letter (A/B/C etc.), as most modified mission types encompass multiple series letters. Sikorsky also sells this helicopter as

128-874: A leaked US embassy cable . On 16 September 2009, the United States Navy delivered the last two of four Mi-17s to the Afghan National Army Air Corps . On 19 June 2010, it was announced that the US government would buy and refurbish 31 more Mi-17 helicopters from Russia to supply the Afghan Air Force. The US was reportedly considering adding the helicopter to the US military for special forces use in order to obscure troop movements. The US has used some Mi-8s and Mi-17s for training, and has purchased units for allies in Iraq, Afghanistan and Pakistan. In August 2010

In September 2010, the Polish Defense Minister announced that his country would buy five new Mi-17s from Russia, to support Polish operations in Afghanistan. All five Mi-17-1Vs were delivered by 2011. In 2011, Chief of Staff of the Afghan National Army Abdul Wahab Wardak announced that

448-545: A cost-cutting measure some nations and services have been tempted to use what are essentially commercial helicopters for military purposes. For example, it has been reported that China is carrying out a rapid enlargement of its assault helicopter regiments with the civilian version of the Russian Mil Mi-17 . These helicopters without armour and electronic counter measures will function well enough for training exercises and photo opportunities but would be suicidal to deploy in

512-580: A development of the Mi-8AMTSh. Modifications include a new large door on the right side, improved Czech -built APU , and Kevlar armour plates around the cockpit area and engines.

704-803: A stabilised mount along with multi-function lasers capable of acting as laser rangefinder and targeting designators for weapons systems. By nature of the mission, the observation helicopter's primary weapons are its sensor suite and communications equipment. Early observation helicopters were effective at calling for artillery fire and airstrikes . With modern sensor suites, they are also able to provide terminal guidance to anti-tank guided weapons, laser-guided bombs and other missiles and munitions fired by other armed aircraft. Observation helicopters may also be armed with combinations of gun and rocket pods and sometimes anti-tank guided missiles or air-to-air missiles , but in smaller quantities than larger attack helicopters. Primarily, these weapons were intended for

768-450: A weakness. Emplaced insurgents and local sympathisers may observe such facilities covertly and gather intelligence on the schedules and routes of patrols and convoys. With this intelligence the insurgents can time their operations to avoid the COIN forces or plan ambushes to engage them, depending on their own tactical situation. Helicopters return a measure of surprise and tactical flexibility to

832-452: Is a multi-purpose helicopter . A utility military helicopter can fill roles such as ground attack , air assault , military logistics , medical evacuation , command and control , and troop transport . While not essential to combat operations, helicopters give a substantial advantage to their operators by being a force multiplier . To maximise their impact, helicopters are utilised in a combined arms approach. High-intensity warfare

896-629: Is characterized by large arrays of conventional armed forces, including mass formations of tanks , with significant air defenses. Helicopter armament and tactics were changed to account for a less-permissive flight environment. Anti-tank missiles , such as the SS.11 and the Aérospatiale SS.12/AS.12 were developed and mounted on French military helicopters. In turn, the United States adapted its BGM-71 TOW for firing from helicopters and eventually developed

960-578: Is known as the Mi-8M series in Russian service. The helicopter is mostly used as a medium twin-turbine transport helicopter , as well as an armed gunship version. Developed from the basic Mi-8 airframe, the Mi-17 was fitted with the larger Klimov TV3-117MT engines, rotors, and transmission developed for the Mi-14 , along with fuselage improvements for heavier loads. Optional engines for " hot and high " conditions are

1024-405: Is placed around the pilots, engines, transmission, and fuel tanks. Fuel lines, control cables and power to the tail rotor may also be shrouded by Kevlar armour. The most heavily armoured helicopters are attack, assault and special forces helicopters. In transport helicopters the crew compartment may or may not be fully armoured, a compromise being to give the passengers Kevlar lined seats but to leave

1088-534: Is that personnel and cargo can be moved to and from locations without requiring a runway for takeoffs and landings. Cargo is carried either internally, or externally by slung load where the load is suspended from an attachment point underneath the aircraft. Personnel are primarily loaded and unloaded while the helicopter is on the ground. However, when the terrain restricts even helicopters from landing, personnel may also be picked up and dropped off using specialized devices, such as rescue hoists or special rope lines, while

1152-605: The AGM-114 Hellfire . Meanwhile, the Soviet Union adapted the 3M11 Falanga missile for firing from the Mil Mi-24 . In the air, attack helicopters armed with anti-tank missiles, and one or more unarmed, or lightly armed scout helicopters operate in concert. The scout helicopter, flying at low level in a nap-of-the-earth approach, attempts to both locate the enemy armoured columns and to map out approaches and ambush positions for

1216-661: The Combat search and rescue (CSAR) mission. Some services use a version of their operational helicopters, usually in the light class, for pilot training. For example, the British have used the Aérospatiale Gazelle both in operations and as a trainer. Some services also have an ab initio phase in training that uses very basic helicopters. The Mexican Navy has acquired a number of the commercially available Robinson R22 and R44 helicopters for this purpose. A utility helicopter

1280-623: The Distinguished Flying Cross for the mission. During the Tham Luang cave rescue in July 2018, the Royal Thai Army used the Mi-17 helicopter for searching operations, and evacuating the first batch of survivors from Tham Luang to Chiang Rai hospital; on 10 July 2018 a Mil Mi-17 helicopter took the last evacuated boy to the hospital.

In 1996 the Government launched an offensive during the dry season at the Khmer Rouge stronghold of Anlong Veng and Pailin , using five Mi-17 gunships and eight Mi-17-Mi-8 troops transports. In May 1999, during Operation Safed Sagar , the Mi-17 was used in the first air phase of the Kargil War by 129HU of the Indian Air Force (IAF) against the Pakistan Army . One IAF Mi-17 and one IAF MiG-21 were shot down by Pakistan Army Air Defence Anza-II shoulder-fired missiles . This led to

1472-679: The Mil Mi-28 N, the Kamov Ka-52 , and the AH-64D Longbow , incorporate sensors and command and control systems to relieve the requirement for scout helicopters. To enhance the combat endurance of these missile-armed helicopters, transport helicopters were used to carry technicians, reloads and fuel to forward locations. Establishing these forward arming and refuel points (FARP) at pre-arranged locations and times allowed armed or attack helicopters to re-arm and refuel, often with their engines running and

1536-563: The S-70 , but it was initially developed as the UH-60 to specific United States Army project requirements. Variants include: Military helicopter Military helicopters play an integral part in the sea, land and air operations of modern militaries. Generally manufacturers will develop airframes in different weight/size classes which can be adapted to different roles through the installation of mission specific equipment. To minimise development costs

1600-614: The US government would buy Mi-17s for use by Afghanistan's troops. He explained the choice of the Russian helicopter over the American Chinook was due to the familiarity of the Afghan technical and pilot staff with the helicopter type and that it is better suited for Afghanistan 's environment. The United States continued to purchase the helicopters for Afghanistan in 2013, despite a congressional prohibition. Overall, 63 Mi-17s were acquired through

1664-554: The aftermath of the American invasion of Iraq helicopters have been used as aerial supply trucks and troop transports to prevent exposure to ambushes set by the Iraqi insurgency . Due to the cost and complexity of training and support requirements, insurgent forces rarely have access to helicopters. The major Western European helicopter manufacturers are Leonardo S.p.A. (formerly AgustaWestland ) and Eurocopter Group . In North America,

In July 2010 two Mi-17 were flown by a mixed crew of United States Air Force and Afghan Air Force personnel in a 13-hour mission that rescued 2,080 civilians from flood waters. This was the largest rescue by two helicopters in USAF history. USAF pilot Lt Col Gregory Roberts received

1856-520: The 1,545 kW (2,072 shp) Isotov TV3-117VM. Recent exports to China and Venezuela for use in high mountains have the new Klimov VK-2500 version of the Klimov TV3-117 engine with FADEC control. The designation Mi-17 is for export; the Russian armed forces call it the Mi-8MT. The Mi-17 is recognisable by the tail rotor on the port side instead of the starboard side, and dust shields in front of

1920-610: The 1960s, the development of the turboshaft engine and transistor technology changed the face of maritime helicopter aviation. The turboshaft engine allowed smaller helicopters, such as the Westland Wasp , to operate from smaller vessels than their reciprocating engine predecessors. The introduction of transistors allowed helicopters, such as the Sikorsky SH-3 Sea King , to be equipped with integral dunking sonar , radar and magnetic anomaly detection equipment. The result

2048-432: The British, Spanish, and Italian navies, the larger helicopters form the main anti-submarine strength of carrier air wings. When operating from shore bases, the helicopters are used as anti-submarine pickets to protect against hostile submarines loitering outside military ports and harbours; their endurance and payload providing advantages over smaller helicopters. Soviet maritime helicopters, operating from its cruisers, had

2112-693: The COIN commander. Patrols need not start and end in the same place (the main entrance of the local compound), nor do supply convoys need follow the same roads and highways. During the Rhodesian Bush War , the Rhodesian military developed and refined " Fireforce " tactics, using small flights of light helicopters, the helicopters would be equipped as gunships to directly attack insurgents with aerial gunfire and also as either an airborne command/observation post or troop transport. Once contact had been established against enemy guerillas paratroopers would be dropped by

2176-578: The Defense Ministry of Belarus for the supply of twelve Mi-8MTV-5 military transport helicopters in 2016–2017.

2304-538: The LZ. The advantage of air assault over an airborne assault is the ability of the helicopters to continually resupply the force during the operation, as well as to transport the personnel and equipment to their previous location, or a follow-on location if the mission dictates. The first reconnaissance and observation aircraft were balloons, followed by light airplanes, such as the Taylorcraft L-2 and Fieseler Fi 156 . As

2368-478: The Longbow radar system, but not enough sets have been bought to equip the whole force. The systems can be fitted to only those airframes that need it, or when finances allow the purchase of enough units. Most military helicopters are armoured to some extent; however, all equipment is limited to the installed power and lift capability and the limits installed equipment places on useful payload. The most extensive armour

2432-647: The Mi-171Sh assault helicopter; the last Mi-17 order was in 2014. In 2021 the website of Russian Helicopters , the manufacturer, said that the Mi-8/17 was "the most widely operated helicopter in history." Royal Cambodian Air Force Mi-17s were used during the Cambodian government 's offensives; by 1994 ten operational airframes were in service, with five converted to helicopter gunships equipped with 57 mm S-5 rocket pods , providing air support for ground forces attacking

2496-619: The Mil Mi-8AMT and Mi-171 helicopters delivered to Kazakhstan until 2025 for local assembly. In 2019, China ordered 100 Mi-171 (including 18 combat-transport Mi-171Sh) and 21 Kazan Ansat helicopters. A contract with the civilian airline QINGDAO for the supply of six Mi-171 helicopters with VK-2500-03 engines was signed in December 2019. In 2019, the Philippine Air Force reportedly expressed its interest in acquiring 16 Mi-171 helicopters for its heavy-lift helicopter requirement, with

2688-607: The additional role of guidance of the cruisers' long range anti-shipping missiles. Maritime helicopters are navalised aircraft for operation from ships. This includes enhanced protection against salt water corrosion , protection against ingestion of water, and provision for forced ditching at sea. As helicopters came into military service, they were quickly pressed into service for search and rescue and medical evacuation . During World War II, Flettner Fl 282s were used in Germany for reconnaissance , and Sikorsky R-4s were used by

2752-462: The aircraft hovers overhead. Air assault is a military strategy that relies heavily on the use of transport helicopters. An air assault involves a customized assault force that is assembled on the pick-up zone and staged for sequential transport to a landing zone (LZ). The idea is to use the helicopters to transport and land a large number of troops and equipment in a relatively short amount of time, in order to assault and overwhelm an objective near

2816-456: The assault role in actual combat situations. The intention of China appears to be to retrofit these helicopters with locally produced electronics and armour when possible, freeing available funds to allow rapid creation of enough regiments to equip each of its Group Armies , allowing a widespread buildup of experience in helicopter operations. Attack helicopters are helicopters used in the anti-tank and close air support roles. The first of

2880-427: The attack helicopters. Late-model scout helicopters include laser designators to guide missiles fired from the attack helicopters. After finding a target, the scout helicopter can locate it and then direct the attack helicopter's missile where to fire. The attack helicopters have only to rise from cover briefly to fire their missiles before returning to a concealed location. Late-development of attack helicopters, such as

2944-533: The basic airframes can be stretched and shortened, be updated with new engines and electronics and have the entire mechanical and flight systems mated to new fuselages to create new aircraft. For example, the Bell UH-1 Iroquois (known as the "Huey") has given rise to a number of derivatives through stretching and re-engining, including the Bell AH-1 . Modern helicopters have introduced modular systems which allow

3008-477: The capability of the early helicopters was as plane guard - tasked with the recovery of pilots who had ditched near an aircraft carrier . As helicopter technology matured with increased payload and endurance , anti-submarine warfare (ASW) was added to the helicopter's repertoire. Initially, helicopters operated as weapons delivery systems, attacking with air-launched torpedoes and depth charges based on information provided by its parent and other warships. In

3072-414: The compartment for the most part unarmoured. Survivability is enhanced by redundancy and the placement of components to protect each other. For example, the Blackhawk family of helicopters uses two engines and can continue to fly on only one (under certain conditions), the engines are separated by the transmission and placed so that if attacked from any one flank, the engine on that flank acts to protect

3136-454: The counter-reconnaissance fight—to eliminate an enemy's reconnaissance assets—but they can also be used to provide limited direct fire support or close air support. Among the first practical uses of helicopters when the Sikorsky R-4 and R-5 became available to British and American forces was deployment from navy cruisers and battleships, at first supplementing and later replacing catapult-launched observation aircraft . Another niche within

3200-417: The engine intakes. Engine cowls are shorter than on the TV2-powered Mi-8, not extending as far over the cockpit, and an opening for a bleed air valve outlet is present forward of the exhaust. Actual model numbers vary by builder, engine type, and other options. As an example, the sixteen new Ulan Ude-built machines delivered to the Czech Air Force in 2005 with -VM model engines were designated as Mi-171Sh,

3264-504: The first military helicopters became available, their ability to both maneuver and to remain in one location made them ideal for reconnaissance. Initially observation helicopters were limited to visual observation by the aircrew, and most helicopters featured rounded, well-glazed cockpits for maximum visibility. Over time, the human eye became supplemented by optical sensor systems. Today, these include low light level television and forward looking infrared cameras. Often, these are mounted in

The Slovak Air Force and Croatian Air Force operated Mi-17s in Kosovo as part of KFOR . Both

3520-402: The maximum size of the helicopters and the minimum size of the ships. Increasing miniaturisation of electronics, better engines and modern weapons now allow even the modern, destroyer-based, multi-role helicopter to operate nearly autonomously in the ASW, anti-shipping, transport, SAR and reconnaissance roles. Medium- and large-sized helicopters are operated from carriers and land bases. In

3584-720: The modern attack helicopters was the Vietnam era Bell AH-1 Cobra , which pioneered the now classic format of pilot and weapons officer seated in tandem in a narrow fuselage, chin mounted guns, and rockets and missiles mounted on stub wings. To enable them to find and identify their targets, some modern attack helicopters are equipped with very capable sensors such as a millimeter wave radar system. Transport helicopters are used for transporting personnel (troops) and cargo in support of military operations. In larger militaries, these helicopters are often purpose-built for military operations, but commercially available aircraft are also used. The benefit of using helicopters for these operations

3648-431: The rotors still turning, and to quickly return to the front lines. In counter-insurgency (COIN) warfare, the government force establishes its presence in permanent or temporary military bases from which to mount patrols and convoys. The government forces seek to deter the insurgent forces from operating, and to capture or kill those that do. The operation of forces from fixed bases linked by a fixed network of roads becomes

To at the same time retain flexibility and limit costs, it is possible to fit an airframe for but not with a system, for example in the US Army's Boeing AH-64D Apache variants are all fitted to be able to take

3776-436: The three primary manufacturers are Boeing ( Boeing Vertol and McDonnell Douglas ), Bell Helicopter and Sikorsky Aircraft . In Japan, the three main manufacturers of helicopters are the aviation arms of the Japanese conglomerates Mitsubishi , Kawasaki and Fuji Heavy Industries . These companies initially followed a business model based on forming strategic partnerships with foreign, usually American, companies with

3840-808: The transmission and the engine on the other side from damage. Aviation electronics, or avionics , such as communication radios and navigation aids are common on most military helicopters. Specialized avionics, such as electronic countermeasures and identification friend or foe systems, are military specific systems that can also be installed on military helicopters. Other payload or mission systems are installed either permanently or temporarily, based on specific mission requirements; optical and IR cameras for scout helicopters, dunking sonar and search radar for anti-submarine helicopters, extra radio transceivers and computers for helicopters used as airborne command posts . Armour, fire suppression, dynamic and electronics systems enhancements are invisible to casual inspection; as
