Army support for the craft was intended to end in 2004; The UH-1 was retired from active Army service in early 2005. During 2009, Army National Guard retirements of the UH-1 accelerated with
12110-434: The 204B with the T58 engine. Because the T58 output shaft is at the rear, and was thus mounted in front of the transmission on the HH-3, it had to have a separate offset gearbox (SDG or speed decreaser gearbox) at the rear, and shafting to couple to the UH-1 transmission. The single-engine UH-1 variants were followed by the twin-engine UH-1N Twin Huey ( Bell 212 ) and years later the UH-1Y Venom . Bell began development of
12283-405: The 20th century, Russian was a mandatory language taught in the schools of the members of the old Warsaw Pact and in other countries that used to be satellites of the USSR. According to the Eurobarometer 2005 survey, fluency in Russian remains fairly high (20–40%) in some countries, in particular former Warsaw Pact countries. In Armenia , Russian has no official status, but it is recognized as
12456-922: The 790th squadron from Divulje military airport near Split , which was under the command of the Yugoslav Navy . In total, the Yugoslav Air Force received 92 Mi-8Ts, designated by the Yugoslav People's Army as the HT-40 , while local modification of several helicopters into electronic warfare variants produced the HT-40E . Some 40 helicopters were equipped for firefighting operations. The Yugoslav Mi-8s' first combat operations were transport of Yugoslav People's Army troops and federal police forces to border crossings in Slovenia on 27 June 1991 during
12629-825: The 92nd aviation brigade of the Army of Republika Srpska comprised 12 Mi-8T helicopters, which continued in service until Operation Koridor . During that period, the Republika Srpska Air Force lost three Mi-8 helicopters to enemy fire. Three helicopters painted in a blue and white colour scheme flew in the first part of 56th helicopter squadron of the Krajina Milicija , using Udbina military airport in Lika as their main base. The Republika Srpska Air Force continued to operate nine helicopters, albeit suffering problems with maintenance and spare parts, until it
12802-900: The American Drug Enforcement Administration (DEA); initially, these were usually borrowed from the U.S. Army to support planned missions, such for Operation Snowcap , a large multi-year counter- narcotics action covering nine countries across Latin America . During the War in Afghanistan , the DEA made use of a number of UH-1s stationed in the country for the purpose of conducting counter-narcotics raids. Operated by contractors, these Hueys provide transportation, surveillance, and air support for DEA FAST teams. During July 2009, four UH-1Hs and two Mi-17s were used in
12975-460: The American president, to save face. A luxury version of the Mi-4 was quickly created and Khrushchev took an inspection flight, during which Mikhail Mil proposed that his helicopter in development was more suitable. However, it would be necessary to have a second engine for reliability. This gave Mikhail Mil the power under the orders of Khrushchev to build the original two-engined helicopter, which for
13148-779: The Army Wing at Utti . All Mi-8s have now been retired. One Mi-8 is on display at the Finnish Aviation Museum in Vantaa , and one is at the Päijänne Tavastia Aviation Museum in Asikkala , near Lahti . The two final Mi-8Ts were given to Hungary in August 2011 with all the remaining spare parts. The Georgian air force started operating Mi-8 and Mi-17 helicopters from 1991 onwards. During

Prior to the Bolshevik Revolution , the spoken form of the Russian language was that of the nobility and the urban bourgeoisie. Russian peasants, the great majority of the population, continued to speak in their own dialects. However,
14186-590: The Institute of Russian Language of the Russian Academy of Sciences, an optional acute accent ( знак ударения ) may, and sometimes should, be used to mark stress . For example, it is used to distinguish between otherwise identical words, especially when context does not make it obvious: замо́к ( zamók – "lock") – за́мок ( zámok – "castle"), сто́ящий ( stóyashchy – "worthwhile") – стоя́щий ( stoyáshchy – "standing"), чудно́ ( chudnó – "this
14359-463: The Iroquois, first flown during August 1961, was also produced in response to Army demands for a version that could accommodate more troops. Further modifications would include the use of all-aluminum construction, the adoption of a rotor brake, and alternative powerplants. The Iroquois was first used in combat operations during the Vietnam War , the first examples being deployed in March 1962. It
14532-601: The Kazan Production Plant, with the first aircraft completed by the end of 1965. The Soviet military originally showed little interest in the Mi-8 until the Bell UH-1 's involvement in the Vietnam War became widely publicised as a great asset to the United States, allowing troops to move swiftly in and out of a battlefield and throughout the country. It was only then that the Soviet military rushed
14705-601: The Lycoming T53-L-11 engine producing 1,100 shp (820 kW). When Bell switched production to the UH-1C, the UH-1E production benefited from the same changes. The Marine Corps later upgraded UH-1E engines to the Lycoming T53-L-13, which produced 1,400 shp (1,000 kW), after the Army introduced the UH-1M and upgraded their UH-1C helicopters to the same engine. The United States Air Force (USAF) held
14878-629: The M60 machine gun. AS-10 and SS-11 missiles were tested in several different configurations. High-capacity rocket launchers were also tested, such as the XM3 launcher, which had 24 launching tubes. Press photos were taken with the XM5 and XM3 installed on the same aircraft, but this arrangement could not be used because it was more than the gross take-off weight of the aircraft. During the Easter Offensive of 1972 by North Vietnam, experimental models of
15051-494: The Mi-8 and Mi-17 are A) the position of the tail rotor (Mi-8 right side, Mi-17 left side), B) the shape of the exhausts (Mi-8 circular, Mi-17 oval), and C) Dust shields in front of engine air intakes for the Mi-17. Also Mi-17 has some improved armour plating for its crew. The naval Mil Mi-14 version is also derived from the Mi-8. The Mi-8 is constantly improving and the newest version still remains in production in 2024. However
15224-612: The Mi-8 and its derivatives being the main aircraft model lost by the Soviet Union in Afghanistan. Between April and May 1986, Mi-8s were used in large numbers to drop radiation-absorbing materials into the No. 4 reactor of Chernobyl Nuclear Power Plant after the Chernobyl disaster , and the fire was extinguished by the combined effort of helicopters dropping over 5000 metric tons of sand, lead, clay, and neutron-absorbing boron onto

Russian is one of the six official languages of
15570-484: The Native American nations . The helicopter quickly developed a nickname derived from its HU-1 designation, which came to be pronounced as "Huey". The reference became so popular that Bell began casting the name on the helicopter's anti-torque pedals. The official U.S. Army name was almost never used in practice. Even after September 1962, at which point the designation for all models was changed to UH-1 under
15743-807: The Russian alphabet include ⟨ ѣ ⟩ , which merged to ⟨ е ⟩ ( /je/ or /ʲe/ ); ⟨ і ⟩ and ⟨ ѵ ⟩ , which both merged to ⟨ и ⟩ ( /i/ ); ⟨ ѳ ⟩ , which merged to ⟨ ф ⟩ ( /f/ ); ⟨ ѫ ⟩ , which merged to ⟨ у ⟩ ( /u/ ); ⟨ ѭ ⟩ , which merged to ⟨ ю ⟩ ( /ju/ or /ʲu/ ); and ⟨ ѧ ⟩ and ⟨ ѩ ⟩ , which later were graphically reshaped into ⟨ я ⟩ and merged phonetically to /ja/ or /ʲa/ . While these older letters have been abandoned at one time or another, they may be used in this and related articles. The yers ⟨ ъ ⟩ and ⟨ ь ⟩ originally indicated
15916-458: The Russian principalities before and especially during Mongol rule. This strengthened dialectal differences, and for a while, prevented the emergence of a standardized national language. The formation of the unified and centralized Russian state in the 15th and 16th centuries, and the gradual re-emergence of a common political, economic, and cultural space created the need for a common standard language. The initial impulse for standardization came from
16089-492: The Serbian air force currently.

During the Kosovo War of 1998 and 1999, the Federal Yugoslav Air Force used Mi-8s for transport of personnel and material to forces in otherwise-inaccessible mountain areas. Evacuation of injured personnel also occurred during the 1999 NATO bombing of Yugoslavia , flying at low altitude to avoid detection by NATO aircraft. In 1999, Yugoslav Mi-8s shot down at least one US Army Hunter UAV with
16781-523: The UH-1C in 1960 in order to correct aerodynamic deficiencies of the armed UH-1B. Bell fitted the UH-1C with a 1,100 shp (820 kW) T53-L-11 engine to provide the power needed to lift all weapons systems in use or under development. The Army eventually refitted all UH-1B aircraft with the same engine. A new rotor system was developed for the UH-1C to allow higher air speeds and reduce the incidence of retreating blade stall during diving engagements. The improved rotor resulted in better maneuverability and
16954-720: The UH-1D and flew operationally from 1963. During its Vietnam War service, the UH-1 was used for various purposes and various terms for each task abounded. UH-1s tasked with ground attack or armed escort were outfitted with rocket launchers, grenade launchers, and machine guns. As early as 1962, UH-1s were modified locally by the companies themselves, who fabricated their own mounting systems. These gunship UH-1s were commonly referred to as "Frogs" or "Hogs" if they carried rockets, and "Cobras" or simply "Guns" if they had guns. UH-1s tasked and configured for troop transport were often called "Slicks" due to an absence of weapons pods. Slicks did have door gunners , but were generally employed in
17127-574: The UH-1F and UH-1P were also added to the unit's inventory and, by the end of the year, the entire unit had shifted from Tan Son Nhut to Nakhon Phanom Royal Thai Air Force Base , with the CH-3s transferring to the 21st Helicopter Squadron . On 1 August 1968, the unit was redesignated the 20th Special Operations Squadron. The 20th SOS's UH-1s were known as the Green Hornets , stemming from their color,

In 1996, the USMC launched the H-1 upgrade program via the award of a contract to Bell Helicopter for development of
17473-537: The US Army had more than 2,800 Iroquois in its inventory; in particular, 389 UH-1Vs comprised 76% of the Army's medevac aircraft. Nevertheless, plans were mooted as early as 1992 to undertake a slow withdrawal of the aging type in favor of larger and more technologically advanced rotorcraft. The US Army began phasing out the UH-1 with the introduction of the Sikorsky UH-60 Black Hawk starting in
17646-604: The USAF announced that the Boeing/Leonardo MH-139 (an AW-139 variant) had won a competition to replace the UH-1N fleet. The UH-1N fleet is in service as of 2024, as production of the new type is ramped up. The US Navy acquired a number of surplus UH-1B helicopters from the U.S. Army, these rotorcraft were modified into gunships, outfitted with special gun mounts and radar altimeters. They were known as Seawolves in service with Navy Helicopter Attack (Light) (HA(L)-3). UH-1C helicopters were also acquired during
17819-467: The United Nations. Education in Russian is still a popular choice for both Russian as a second language (RSL) and native speakers in Russia, and in many former Soviet republics. Russian is still seen as an important language for children to learn in most of the former Soviet republics. In Belarus , Russian is a second state language alongside Belarusian per the Constitution of Belarus . 77% of
17992-859: The West German Bundeswehr . These saw service with both the German Army and German Air Force as utility helicopters, they were also commonly used for search and rescue (SAR) missions. After being replaced by newer twin-engine Eurocopter EC145s , the last UH-1Ds in German service were withdrawn on 12 April 2021. Israel withdrew its UH-1s from service in 2002, after 33 years of operation. They were replaced by Sikorsky UH-60 Blackhawk helicopters with an initial batch of 10 delivered during 1994. While some were passed on to pro-Israeli militias in Lebanon, eleven other UH-1Ds were reportedly sold to
18165-478: The XH-40 first flew on 20 October 1956, at Fort Worth , Texas , with Bell's chief test pilot, Floyd Carlson, at the controls. Even prior to the first flight, the Army had placed an order for six YH-40 service test helicopters. During 1957, a further two prototypes were completed. In 1959, the Army awarded Bell a production contract for 182 aircraft, which was designated "HU-1A" and officially named Iroquois after
18338-562: The airspeed across the rotor blade, reducing its overall effective yaw authority. The Finnish Defence Forces and the Finnish Border Guard began using Mi-8s in the 1970s, with the Finnish Air Force receiving its first, serialed HS-2, on 28 May 1973, and the second, HS-1, on 31 May 1973. Six Mi-8Ts were obtained at first, followed by further two Mi-8Ts and two Mi-8Ps. Three of the helicopters were handed over to
18511-403: The broader sense of expanding the use of Russian alongside or in favour of other languages. The current standard form of Russian is generally regarded as the modern Russian literary language ( современный русский литературный язык – "sovremenny russky literaturny yazyk"). It arose at the beginning of the 18th century with the modernization reforms of the Russian state under the rule of Peter
18684-399: The burning reactor and injecting liquid nitrogen into it. Most of the helicopters were severely irradiated and abandoned in a giant junkyard, the so-called "machines cemetery" near Chernobyl, with several disappearing from the site in later years. During the initial operation, one crashed near the power plant after hitting a construction crane cable with all the crew of four being killed in
18857-483: The cabin is via two aft-sliding doors and two small, forward-hinged panels. The doors and hinged panels may be removed for flight or the doors may be pinned open. Pilot access is via individual hinged doors. The UH-1H's dual controls are conventional for a helicopter and consist of a single hydraulic system boosting the cyclic stick, collective lever and anti-torque pedals. The collective levers have integral throttles, although these are not used to control rotor rpm, which
19030-467: The conflict, 7,013 UH-1s served in Vietnam and of these 3,305 were destroyed. In total, 1,151 pilots were killed, along with 1,231 other crew members (these figures are not including Army of the Republic of Vietnam losses). Post Vietnam, the US Army continued to operate large numbers of Iroquois; they would see further combat during the US invasion of Grenada in 1983, the US invasion of Panama in 1989, and
19203-504: The council of ministers to proceed with production. Due to the position of the engine, this enabled Mikhail Mil to justify redesigning the entire front half of the aircraft around the single engine. The prototype, which was named V-8, was designed in 1958 and based on the Mil Mi-4 with a larger cabin. Powered by an AI-24 2,010 kW (2,700 shp) Soloviev turboshaft engine, the single engined V-8 prototype had its maiden flight in June 1961 and

In Vietnam , Russian has been added in the elementary curriculum along with Chinese and Japanese and were named as "first foreign languages" for Vietnamese students to learn, on equal footing with English. The Russian language
19549-592: The crash. It is now known that virtually none of the neutron absorbers reached the core. On 16 August 2013, the Ministry of Defense of Ukraine reported that one of its Mi-8MSB had set a world altitude record of 9,150 metres (30,020 ft) at the Kirovske military airfield on 15 August. The Ukrainian Armed Forces used Mi-8MSB along with Mi-24s in operations against separatists in Eastern Ukraine during
19722-555: The crews of aircraft forced down. As most flights were made behind the front, the Croatian forces were able to down just one helicopter, which was hit by small arms fire near Slavonski Brod on 4 October 1991. After Bosnian Serbs declared their state in the spring of 1992, some former Yugoslav Air Force Mi-8s continued service with the Republika Srpska armed forces. The inventory of the 82nd mixed helicopter squadron, of
19895-666: The decision that all battlefield helicopters would be operated by the Australian Army. On 21 September 2007, the Australian Army retired the last of their Bell UH-1s. The last flight occurred in Brisbane on that day with the aircraft replaced by MRH-90 medium helicopters and Tiger armed reconnaissance helicopters. The Royal Australian Navy 's 723 Squadron also operated seven UH-1B from 1964 to 1989, with three of these aircraft lost in accidents during that time. 723 Squadron deployed Iroquois aircraft and personnel as part of
20068-755: The door gunner's 7.62 mm machine gun. Two Mi-17V helicopters secretly operated by the Special Operations Unit post-1997 were also active during the Kosovar conflict. After the unit disbanded in 2003, the helicopters were transferred to Serbia and Montenegro's air force . As of mid-2020, the Serbian Air Force , the successor of the Federal Yugoslav Air Force, operates a small amount of Mi-8T which are now being replaced by Mi-17 helicopters. There are 13 Mi-17 in
20241-472: The door guns. The XM-94 grenade launcher had been tested on Army rotorcraft prior to its use by the USAF. The unit was capable of firing 400 grenades per minute, up to 1,500 yards effective range. Into the twenty-first century, the USAF operates the UH-1N for support of intercontinental ballistic missile (ICBM) sites, including transport of security personnel and distinguished visitors. On 24 September 2018,
20414-479: The early years of the Vietnam War. UH-1B/C gunships were replaced by the new AH-1 Cobra attack helicopter from 1967 to late 1968. The increasing intensity and sophistication of NVA anti-aircraft defenses made continued use of UH-1 gunships impractical, and after Vietnam the Cobra was adopted as the Army's main attack helicopter. Devotees of the UH-1 in the gunship role cite its ability to act as an impromptu Dustoff if
20587-506: The emergence and effectiveness of turbines used in the Mil Mi-6 . After design and development, the Mi-8 was subsequently introduced into the Soviet Air Force in 1967. The Soviet military originally argued against a new helicopter, as they were content with the current Mil Mi-4 . To counter this, Mikhail Mil proposed that the new helicopter was more of an update to new turbine engines rather than an entirely new helicopter, which persuaded

21625-410: The first UH-1As were being delivered. In response, Bell proposed the UH-1B, equipped with the Lycoming T53-L-5 engine producing 960 shp (720 kW) and a longer cabin that could accommodate either seven passengers or four stretchers and a medical attendant. Army testing of the UH-1B started in November 1960, with the first production aircraft delivered in March 1961. Bell commenced development of
21798-417: The first time in Soviet history would need purpose-built turbine engines, rather than those adapted from fixed wing aircraft (as in the Mil Mi-6 and the first prototype V-8) and an entirely new main rotor gear box that would be designed in-house for the first time. In May 1960, the order was given for Mikhail Mil to create his twin engine helicopter. The Sergei Isotov Design Bureau accepted the task of creating
21971-518: The following years, the country expanded its UH-1 fleet further with assistance from the US government. Several Salvadorean UH-1M and UH-1H helicopters used were modified to carry bombs instead of rocket pods. The UH-1s enabled the military to avoid ground routes vulnerable to guerilla ambushes; the gunships were typically used to suppress hostile forces ahead of troops being inserted by UH-1 transports. The German aerospace company Dornier constructed 352 UH-1Ds under license between 1967 and 1981 for
22144-435: The former Soviet Union . Russian has remained an official language of the Russian Federation , Belarus , Kazakhstan , Kyrgyzstan , and Tajikistan , and is still commonly used as a lingua franca in Ukraine , Moldova , the Caucasus , Central Asia , and to a lesser extent in the Baltic states and Israel .

22317-505: The generation of immigrants who started arriving in the early 1960s). Only about 25% of them are ethnic Russians, however. Before the dissolution of the Soviet Union , the overwhelming majority of Russophones in Brighton Beach, Brooklyn in New York City were Russian-speaking Jews. Afterward, the influx from the countries of the former Soviet Union changed the statistics somewhat, with ethnic Russians and Ukrainians immigrating along with some more Russian Jews and Central Asians. According to
22490-480: The government bureaucracy for the lack of a reliable tool of communication in administrative, legal, and judicial affairs became an obvious practical problem. The earliest attempts at standardizing Russian were made based on the so-called Moscow official or chancery language, during the 15th to 17th centuries. Since then, the trend of language policy in Russia has been standardization in both the restricted sense of reducing dialectical barriers between ethnic Russians, and
22663-417: The helicopter. On 26 August 2014, a UTair Aviation owned Mi-8 working for the United Nations crashed as it approached a landing airstrip near Bentiu. Three of the Russian crew members died and one was injured. Rebel commander Peter Gadet claimed that his forces brought it down using a rocket-propelled grenade. The Mi-8 family of helicopters became the main Soviet (and later Russian) helicopter, covering
22836-401: The improved UH-1Y and AH-1Zs variants. The UH-1Y includes a lengthened cabin, four-blade rotor, and two more powerful GE T700 engines. The UH-1Y entered service with the USMC in 2008.
