3 Best Heavy Transport Chopper In The World

The CH-53 Sea Stallion is the most common name for the Sikorsky S-65 family of heavy-lift transport helicopters. Originally developed for use by the United States Marine Corps, it is also in service with Germany, Iran, Israel, and Mexico. The United States Air Force operated the HH-53 "Super Jolly Green Giant" during the late- and post-Vietnam War era, updating most of them as the MH-53 Pave Low. The dimensionally-similar CH-53E Super Stallion is a heavier-lifting, improved version designated S-80E by Sikorsky. Its third engine makes it more powerful than the Sea Stallion, which it has replaced in the heavy-lift mission.The Sea Stallion has a fuselage design similar to the Sikorsky S-61R/Jolly Green Giant series. It has a passenger door on the right side of the fuselage behind the cockpit and a power-operated rear loading ramp. The fuselage was watertight, though not intended for amphibious use, and only landed on water in emergencies. The Stallion has mechanical flight controls which are backed by three independent hydraulic systems. Armor protects crew and vital systems. The CH-53A carries a crew of four; pilot, copilot, crew chief, and an aerial observer, a load of 38 troops, 24 litters with medical attendants, an internal cargo load of 8,000 pounds (3,600 kg) or an external load of 13,000 pounds (5,900 kg) on the single-point sling hook. The CH-53A is equipped with a pair of 7.62 mm M60 machine guns that point out to each side of the fuselage. The CH-53D features uprated engines, initially T64-GE-412 with 3,695 shp (2,755 kW) then the T64-413 with 3,925 shp (2,927 kW) with an uprated transmission. Its interior added seats to allow for 55 troops. CH-53Ds are generally armed with twin .50 BMG (12.7 mm) M2/XM218 machine guns. In later years, CH-53Ds have been fitted with defensive countermeasures including an AN/ALE-39 chaff dispenser and an AN/ALQ-157 infrared countermeasure. The CH-53A features a six-bladed main rotor and four-bladed tail rotor developed from those used on the S-64 Skycrane. To save space on board naval vessels, the tail boom and the rotors folded. Initially, the CH-53 was powered by twin General Electric T64-6 turboshaft engines providing 2,850 shaft horsepower (2,130 kW) each, each engine being located on the upper fuselage. Later engines included the T64-1 with 3,080 shp (2,300 kW) and the T64-16 with 3,485 shp (2,599 kW). The HH-53B featured T64-3 engines producing 3,080 shp (2,300 kW).

Later production CH-53Ds featured a Blade Inspection Method (BIM) scheme to detect cracks in its metal rotors. BIM involved pressurizing the interior of the rotor blades with nitrogen. If a crack is present pressure is lost and a red indicator on the rotor blade tip was tripped. Later, the BIM system was connected to a cockpit display. BIM reduced the need to swap out rotor blades on a routine basis.

The British Boeing Chinook is a tandem rotor helicopter operated by the Royal Air Force. A series of variants based on the United States Army's Boeing CH-47 Chinook, the RAF Chinook fleet is the largest outside the United States. RAF Chinooks have seen extensive service including fighting in the Falklands War, peace-keeping commitments in the Balkans, and action in the Iraq and Afghanistan wars. The Chinook HC2 aircraft, normally based at RAF Odiham, provides heavy-lift support and transport across all branches of the British armed forces, and is supported by the smaller, medium-lift helicopters such as the AgustaWestland Merlin HC3 and the Westland Puma HC1, based at RAF Benson and RAF Aldergrove. 

In March 1967 an order was placed for fifteen Chinook HC1s, standing for Helicopter, Cargo Mark 1, for the Royal Air Force to replace the Bristol Belvedere. This original HC1 variant was to be based on the CH-47B but the order was cancelled in a review of defence spending in November 1967, UK Chinook procurement ambitions were revived in 1978 with an announced requirement for a new heavy-lift helicopter to replace the Westland Wessex. Thirty Chinooks were ordered at a price of US$200 million. These helicopters, comparable to the CH-47C with Lycoming T55-L-11E engines, were again designated Chinook HC1, and entered service in December 1980. Eight more HC1s were delivered from 1984 to 1986 with the CH-47D's Lycoming T55-L-712 turboshafts. The replacement of the HC1's metal rotor blades with aluminium and glass fibre composite rotor blades saw these aircraft designated Chinook HC1B. All surviving aircraft were later returned to Boeing and updated to the Chinook HC2 standard for further service within the RAF. The US Army's next generation Chinook, the CH-47D, entered service in 1982. Improvements from the CH-47C included upgraded engines, composite rotor blades, a redesigned cockpit to reduce pilot workload, redundant and improved electrical systems, an advanced flight control system (FCS) and improved avionics. The RAF returned their original HC1s to Boeing for upgrading to CH-47D standard, the first of which returned to the UK in 1993.

Three additional HC2 Chinooks were ordered with delivery beginning in 1995. Another six were ordered in 1995 under the Chinook HC2A designation;^[11] the main difference between these and the standard HC2 was the strengthening of the front fuselage to allow the fitting of an aerial refueling probe in future. One Argentine CH-47C was captured during the Falklands War, and used by the RAF as a training aid. The rear fuselage was later used to repair a crashed RAF Chinook in 2003. In 2006, the retirement dates for the HC2 and HC2A fleets were scheduled for 2015 and 2025 respectively, but if planned upgrades are made both types could expect to be flying until 2040.

The American Boeing CH-47 Chinook is an American twin-engine, tandem rotor heavy-lift helicopter. With a top speed of 170 knots (196 mph, 315 km/h) it is faster than contemporary utility and attack helicopters of the 1960s. The CH-47 is one of the few aircraft of that era – along with the fixed-wing Lockheed C-130 Hercules cargo aircraft – that is still in production and front line service, with over 1,179 built to date. Its primary roles include troop movement, artillery emplacement and battlefield resupply. It has a wide loading ramp at the rear of the fuselage and three external-cargo hooks. The Chinook was designed and initially produced by Boeing Vertol in the early 1960s. The helicopter is now produced by Boeing Rotorcraft Systems. Chinooks have been sold to 16 nations with the US Army and the Royal Air Force (see Boeing Chinook (UK variants)) being the largest users. The CH-47 is among the heaviest lifting Western helicopters. Improved and more powerful versions of the CH-47 have been developed since the helicopter entered service. The US Army's first major design leap was the now-common CH-47D, which entered service in 1982. Improvements from the CH-47C included upgraded engines, composite rotor blades, a redesigned cockpit to reduce pilot workload, improved and redundant electrical systems, an advanced flight control system and improved avionics. The latest mainstream generation is the CH-47F, which features several major upgrades to reduce maintenance, digitized flight controls, and is powered by two 4,733-horsepower Honeywell engines. A commercial model of the Chinook, the Boeing-Vertol Model 234, is used worldwide for logging, construction, fighting forest fires, and supporting petroleum extraction operations. On 15 December 2006, the Columbia Helicopters company of the Salem, Oregon, metropolitan area, purchased the Type Certificate of the Model 234 from Boeing. The Chinook has also been licensed to be built by companies outside of the United States, such as Elicotteri Meridionali (now AgustaWestland) in Italy, Kawasaki in Japan.

11 Best Modern Helicopter In The World

The Boeing-Sikorsky RAH-66 Comanche was an advanced five-blade armed reconnaissance and attack helicopter designed for the United States Army. The RAH-66 program was canceled in 2004, before mass production began, after nearly $7 billion was spent on the program. During the early 1980s, the U.S. Army began formulating a requirement for the replacement of its helicopters then in service, resulting in the Light Helicopter Experimental program. In 1991, the Boeing-Sikorsky team was chosen to produce prototypes. The Comanche would incorporate stealth technologies, featuring a number of designs previously untried. It was to employ advanced sensors in its reconnaissance role, and was intended to designate targets for the AH-64 Apache. The aircraft was also armed with missiles and rockets to destroy armored vehicles. Two RAH-66 prototypes were built and conducted flight testing from 1996 to 2004. Since the cancellation the prototypes have been placed on display. The RAH-66 was intended to be a stealth helicopter; it incorporated multiple techniques in order to reduce its radar cross-section (RCS) and other areas of visibility. Its outer surfaces were faceted and had radar-absorbent material (RAM) coatings and infrared-suppressant paint applied; with these measures, the Comanche's RCS was 360 times smaller than the AH-64 Apache attack helicopter. The Comanche's noise signature was noticeably quieter than comparative helicopters; this was partly achieved through the all-composite 5-blade main rotor and tail rotor assembly. The Comanche was equipped with sophisticated navigation and detection systems intended to allow operations at night and in bad weather. Each of the two crew-members had two LCD multi-functional displays in addition to the Helmet-Integrated Display and Sight System (HIDSS). It has a digital fly-by-wire flight control system. Its primary mission was to use its advanced sensors to find and designate targets for attack helicopters, such as the AH-64. The RAH-66 also had its own light armament – it could carry six AGM-114 Hellfire and twelve AIM-92 Stinger missiles split evenly between the two retractable weapons pylons. The Comanche was also to be fitted with the 20 mm three-barrel XM301 cannon under its nose. More armament could be mounted externally on stub wings but would reduce the effectiveness of stealth technologies. On 23 February 2004, the U.S. Army announced their decision to cancel the RAH-66 Comanche program. The Army determined upgrades would be required for the RAH-66 to survive current anti-aircraft threats and decided to put the funding toward renovating its existing helicopter fleet of attack, utility, and reconnaissance aircraft. The Army also planned to use the program's funds to speed up development of unmanned aerial vehicles (UAVs). The Comanche program had spent US$6.9 billion at the time of its termination. Contract termination fees were estimated to total US$450–680 million for the main program partners Sikorsky and Boeing. The Army subsequently pursued the Bell ARH-70 to replace the OH-58D, but the ARH-70 was also canceled in October 2008, due to cost overruns.

The Boeing AH-64 Apache is a four-blade, twin-engine attack helicopter with a tailwheel-type landing gear arrangement, and a tandem cockpit for a two-man crew. Originally, the Apache started life as the Model 77 developed by Hughes Helicopters for the United States Army's Advanced Attack Helicopter program to replace the AH-1 Cobra, and was first flown on 30 September 1975. The AH-64 was introduced to U.S. Army service in April 1986. The AH-64 Apache features a nose-mounted sensor suite for target acquisition and night vision systems. It is armed with a30-millimeter (1.2 in) M230 Chain Gun carried between the main landing gear, under the aircraft's forward fuselage. It has four hardpoints mounted on stub-wing pylons, typically carrying a mixture of AGM-114 Hellfire missiles and Hydra 70 rocket pods. The AH-64 has a large amount of systems redundancy to improve combat survivability. The U.S. Army selected the AH-64, by Hughes Helicopters, over the Bell YAH-63 in 1976, and later approved full production in 1982. McDonnell Douglas continued production and development after purchasing Hughes Helicopters from Summa Corporation in 1984. The first production AH-64D Apache Longbow, an upgraded version of the original Apache, was delivered to the Army in March 1997. Production has been continued by Boeing Defense, Space & Security; over 1,000 AH-64s have been produced to date. The U.S. Army is the primary operator of the AH-64; it has also become the primary attack helicopter of multiple nations, including Greece, Japan, Israel, the Netherlands and Singapore; as well as being produced under license in the United Kingdom as the AgustaWestland Apache. U.S. AH-64s have served in conflicts in Panama, the Persian Gulf, Kosovo,Afghanistan, and Iraq. Israel has made active use of the Apache in its military conflicts in Lebanon and the Gaza Strip; both British and U.S. AH-64s have seen deployments in Afghanistan and Iraq. The AH-64 Apache has a four-blade main rotor and a four-blade tail rotor. The crew sits in tandem, with the pilot sitting behind and above the copilot/gunner. The crew compartment has shielding between the cockpits, such that at least one crew member can survive hits. The compartment and the rotor blades are designed to sustain a hit from 23-millimeter (0.91 in) rounds. The airframe includes some 2,500 pounds (1,100 kg) of protection against ballistic strikes. The Apache also uses a self-sealing fuel system to protect against the loss of fuel caused by ballistic projectiles.

The Kamov Ka-50 "Black Shark"/ "Hokum A" is a single-seat Russian attack helicopter with the distinctive coaxial rotor system of the Kamov design bureau. It was designed in the 1980s and adopted for service in the Russian army in 1995. It is currently manufactured by the Progress company in Arsenyev. It is being used as a heavily armed scout helicopter. During the late 1990s, Kamov and Israel Aerospace Industries developed a tandem-seat cockpit version, the Kamov Ka-50-2 "Erdogan", to compete in Turkey's attack helicopter competition. Kamov also designed another two-seat variant, the Kamov Ka-52 "Alligator" / "Hokum B". The aircraft carries a substantial load of weapons in four external hardpoints under the stub wings plus two on the wingtips, a total of some 2,000 kg depending on the mix. The main armament are the twelve laser-guided Vikhr anti-tank missiles (transl. Vortex) with a maximum range of some 8 km. The laser guidance is reported to be virtually jam-proof and the system features automatic guidance to target, enabling evasive action immediately after missile launch. The fire control system automatically shares all target information among the four Black Sharks of a typical flight in real time, allowing one helicopter to engage a target spotted by another, and the system can also input target information from ground-based forward scouts with personnel-carried target designation gear.

The Mil Mi-28 (NATO reporting name 'Havoc') is a Russian all-weather, day-night, military tandem, two-seat anti-armor attack helicopter. It is a dedicated attack helicopter with no intended secondary transport capability, better optimized than the Mil Mi-24 for the role. It carries a single gun in an undernose barbette, plus external loads carried on pylons beneath stub wings. The Mi-28 has two heavily armored cockpits, a windshield able to withstand hits from 12.7–14.5 mm caliber bullets, a nose equipped with electronics, and a narrow-X tail rotor (55 deg) with reduced noise characteristics. It is powered by two 2,200 hp Isotov TV-3-117VM (t/n 014) turboshaft engines. While the Mi-28 is not intended for use as a transport, it does have a small passenger compartment capable of carrying three people. The planned purpose of this is to enable the rescue of downed helicopter crews. The Mi-28N features a helmet mounted display for the pilot. The pilot would designate targets for the Navigator/Weapons Officer, who proceeds to fire the weapons required to fulfill that particular task.
 

The Bell AH-1 Cobra (company designation: Model 209) is a two-bladed, single engine attack helicopter manufactured by Bell Helicopter. It shares a common engine, transmission and rotor system with the older UH-1 Iroquois. The AH-1 is also referred to as the HueyCobra or Snake. The AH-1 was the backbone of the United States Army's attack helicopter fleet, but has been replaced by the AH-64 Apache in Army service. Upgraded versions continue to fly with the militaries of several other nations. The AH-1 twin engine versions remain in service with United States Marine Corps (USMC) as the service's primary attack helicopter. Surplus AH-1 helicopters have been converted for fighting forest fires. The United States Forest Service refers to their program as the Firewatch Cobra. Garlick Helicopters also converts surplus AH-1s for forest firefighting under the name, FireSnake. 

The Agusta A129 Mangusta (English: Mongoose) is an attack helicopter originally designed and produced by Agusta in Italy. It was the first attack helicopter to be designed and produced wholly in Western Europe. The TAI/AgustaWestland T-129 ATAK is a derivative version of the A129, and its development is the responsibility of Turkish Aerospace Industries (TAI), with Agusta Westland as the primary partner. The Italian Army began to form a need for a light observation and anti-tank helicopter in 1972. West Germany had a similar need. The nations' requirements led to a joint project between the Italian company Agusta and West Germany company MBB. However the joint effort ended after preliminary work. Agusta initially studied an A109-based design, but moved to new design. The company began design work on the A129 in 1978. The first of five A129 prototypes took the type's maiden flight on 11 September 1983, and the fifth prototype first flew in March 1986. Italy ordered 60 A129s.

The WZ-10 is an attack helicopter developed by the People's Republic of China. It is designed primarily for anti-tank missions but is believed to have a secondary air-to-air capability as well. It is being built by Changhe Aircraft Industries Corporation (CAIC). In 1979, the Chinese military studied the problem of countering large armour formations. It concluded that the best conventional solution were attack helicopters. Eight Aérospatiale Gazelle armed with Euromissile HOT were procured for evaluation. By the mid-1980s, the Chinese decided a dedicated attack helicopter was required. At the time, they used civilian helicopters converted for the military; these were no longer adequate in the attack role, and suitable only as scouts. Following this, China evaluated the Agusta A129 Mangusta, and in 1988 secured an agreement with the USA to purchase AH-1 Cobras and a license to produce BGM-71 TOW missiles; the latter was cancelled following the Tiananmen Square protests of 1989 and the resulting arms embargo. The colour revolutions prevented the purchase of attack helicopters from Eastern Europe in 1990 and 1991; Bulgaria and Russia rejected Chinese offers to purchase the Mil Mi-24. While attempting to import foreign designs failed, war games determined that attack helicopters had to be commanded by the army, rather than the air force. This led to the formation of the People's Liberation Army Ground Force Aircraft (PLAGFAF), with an initial strength of 9 Harbin Z-9. The PLAGFAF conducted tactical experiments that would help define the future WZ-10's requirements. Research also decided that anti-tank missiles like the BGM-71 TOW were inadequate, and favoured an analogue to the AGM-114 Hellfire. These findings ensured the WZ-10 would be based around the new missile.

The HAL Light Combat Helicopter (LCH) is a multirole combat helicopter being developed in India by Hindustan Aeronautics Limited (HAL) for use by the Indian Air Force and the Indian Army. The failure of the Russian built Mi-35 to perform satisfactorily in the high altitude battle zones of Kargil highlighted the requirement of an attack helicopter specially made for such operations. In 2006, HAL announced its plans to indigenously design and build the LCH; funds for designing and developing the LCH to meet the requirements of the Indian Army and the Indian Air Force were sanctioned in October 2006. The helicopter has a maximum weight of 5.5 tonnes, and has a service ceiling of 6,500 meters. The LCH is a derivative of the HAL Dhruv, which was inducted into the Indian armed forces. Basing on an existing helicopter is expected to greatly reduce LCH project costs, which is pegged at3.76 billion (US$68.4 million). The Indian Air Force is to acquire 65 LCHs and Indian Army is to acquire 114 LCHs. The LCH was expected to be ready for the Initial Operational Clearance (IOC) by December 2010 with the Final Operational Clearance (FOC) in 2011. However, the revised timeframes for LCH should be ready for induction into IAF by 2012-2013.

The Denel Rooivalk (previously designated AH-2 and CSH-2) is an attack helicopter manufactured by Denel of South Africa. Rooivalk is Afrikaans for "Red Kestrel".

The South African Air Force (SAAF) ordered 12 Rooivalks, designated the Rooivalk Mk 1 in SAAF service, the first of was officially handed over in April 2011. The helicopters are flown by 16 Squadron, which is based at AFB Bloemspruit near Bloemfontein. Due to the SAAF's decades of helicopter experience in the harsh African environment, the Rooivalk has been designed to operate for prolonged periods without sophisticated support. All that is needed to keep the Rooivalk flying is a medium transport helicopter equipped with a basic spares supply plus four groundcrew.

The Rooivalk carries a range of weapons depending on the mission profile. It is generally fitted with a nose-mounted 20 mm cannon and can also carry air-to-air missiles, anti-armour missiles and unguided rockets. The Rooivalk has a fire control system for target acquisition and tracking as well as an advanced navigation system using Doppler radar and GPS. Also incorporated is an electronic countermeasures suite coupled with chaff and flare dispensers.

The Mil Mi-24 Hind is a large helicopter gunship and attack helicopter and low-capacity troop transport with room for eight passengers. It is produced by Mil Moscow Helicopter Plant and operated since 1972 by the Soviet Air Force, its successors, and more than 30 other nations.

In NATO circles, the export versions, Mi-25 and Mi-35, are denoted with a letter suffix as "Hind D" and "Hind E" respectively. Soviet pilots called the Mi-24 the "flying tank". More common unofficial nicknames were "Crocodile" due to the helicopter's camouflage scheme and "Glass" because of the flat glass plates which surround the cockpit of the Mi-24. 

The Sikorsky UH-60 Black Hawk is a four-bladed, twin-engine, medium-lift utility helicopter manufactured by Sikorsky Aircraft. Sikorsky submitted the S-70 design for the United States Army's Utility Tactical Transport Aircraft System (UTTAS) competition in 1972. The Army designated the prototype as the YUH-60A and selected the Black Hawk as the winner of the program in 1976, after a fly-off competition with the Boeing Vertol YUH-61.

The UH-60A entered service with the Army in 1979, to replace the Bell UH-1 Iroquois as the Army's tactical transport helicopter. This was followed by the fielding of electronic warfare and special operations variants of the Black Hawk. Improved UH-60L and UH-60M utility variants have also been developed. Modified versions have also been developed for the U.S. Navy, Air Force, and Coast Guard. In addition to U.S. Army use, the UH-60 family has been exported to several nations. Black Hawks have served in combat during conflicts in Grenada, Panama, Iraq, Somalia, the Balkans, Afghanistan, and other areas in the Middle East.
