3906-702: The Army procure the Vertol -built medium transport helicopter. However, funding for full-scale development was not then available, and the Army vacillated on its design requirements. Some officials in Army Aviation thought that the new helicopter should be operated as a light tactical transport aimed at taking over the missions of the old piston-engined Piasecki H-21 and Sikorsky H-34 helicopters, and be consequently capable of carrying about 15 troops (one squad ). Another faction in Army Aviation thought that

The German government announced in June 2022 that the CH-47F Block 2 was selected as the winner of its heavy helicopter program to replace its Sikorsky CH-53G Sea Stallion fleet. Germany
4092-571: The Chinook fleet was used for casualty evacuation, and due to the very heavy demand for the helicopters, they were usually overburdened with wounded. Perhaps the most cost effective use of the Chinook was the recovery of other downed aircraft. At the war's peak the US Army had 21 Chinook companies in Vietnam. Pilots discovered the CH-47A's transmission system could not handle the two gas turbines running at full power, and high humidity and heat reduced
4185-431: The Chinook presented a major problem of "customer education". Commanders and crew chiefs had to be constantly alert that eager soldiers did not overload the temptingly large cargo compartment. It would be some time before troops would be experts at using sling loads. The Chinook soon proved to be such an invaluable aircraft for artillery movement and heavy logistics that it was seldom used as an assault troop carrier. Some of

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
5580-697: The assault missions and too light for transport purposes. While the YHC-1A would be improved and adopted by the U.S. Marine Corps as the CH-46 Sea Knight , the Army sought a heavier transport helicopter, and ordered an enlarged derivative of the V-107 with the Vertol designation Model 114. Initially designated as the YCH-1B , on 21 September 1961, the preproduction rotorcraft performed its maiden flight . In 1962,

The T55-L-11 engines were less reliable, as they had been hurriedly introduced to increase payload; thus, they were temporarily replaced by
6231-405: The following loads: The soldiers will also conduct an actual hook-up of a load underneath a CH-47 or UH-60 aircraft. Soldiers must pass two tests to move on to the next phase: Soldiers are allowed one retest per exam. The 3-day Phase Three (Rappelling Phase) includes instruction on basic ground and aircraft rappelling procedures: Soldiers conduct two rappels on the wall side of
6324-536: The gunners from firing into the rotor blades. Dust filters were also added to improve engine reliability. Of the nearly 750 Chinook helicopters in the U.S. and South Vietnam fleets, about 200 were lost in combat or wartime operational accidents. The U.S. Army CH-47s supported the 1st Australian Task Force as required. Four CH-47s were converted into ACH-47As by adding armor and improved engines. Its armament included two fixed forward firing M24A1 20 mm cannons , one turret with 40 mm automatic grenade launcher on
6417-445: The helicopter has been exported to nations across the world; the U.S. Army and the Royal Air Force (see Boeing Chinook (UK variants) ) have been its two largest users. The civilian version of the Chinook is the Boeing Vertol 234. It has been used by civil operators not only for passenger and cargo transport, but also for aerial firefighting and to support logging , construction , and oil extraction industries. During late 1956,
6510-471: The helicopter was considerably faster than contemporary 1960s utility helicopters and attack helicopters , and is still one of the fastest helicopters in the US inventory. Improved and more powerful versions of the Chinook have also been developed since its introduction; one of the most substantial variants to be produced was the CH-47D, which first entered service in 1982; improvements from the CH-47C standard included upgraded engines, composite rotor blades,
6603-422: The helicopter's rear pylon and connected to the rotors by drive shafts. Initial models were fitted with Lycoming T55 engines rated at 2,200 hp (1,600 kW) each. The counter-rotating rotors eliminate the need for an antitorque vertical rotor, allowing all power to be used for lift and thrust. The ability to adjust lift in either rotor makes it less sensitive to changes in the center of gravity, important for
6696-678: The items, and all items must be laid out "as worn." Students must complete a two-mile (3.2 km) run in under 18 minutes to receive a "GO" — i.e., satisfactory completion of the event. The uniform for the run is Army Combat Uniform (minus the ACU Top depending on the season in which the training cycle begins) with running shoes. Next is an obstacle course designed to assess a student's upper body strength, agility, endurance, confidence, and ability to perform at heights without displaying fear or distress. There are nine obstacles: two mandatory obstacles (failing either will result in being dropped from
6789-464: The maximum lift by more than 20% in the low lands and 30% in mountain areas. More powerful, improved transmission and strengthened fuselages arrived in 1968 with the CH-47B, followed a few months later by the CH-47C. The CH-47s in Vietnam were generally armed with a single 0.308 in ( 7.62 mm ) M60 machine gun on a pintle mount on either side of the aircraft for self-defense, with stops fitted to keep
6882-510: The more reliable Lycoming T55-L-7C. The Super C was distinguishable from the standard "C" by the uprated maximum gross weight. The type was not approved by the FAA for civil aviation due to the nonredundant hydraulic flight boost system drive. The hydraulic system was redesigned for the succeeding CH-47D, allowing it to achieve certification as the Boeing Model 234. A total of 233 CH-47Cs were built. Canada bought eight CH-47Cs; deliveries of
6975-401: The new helicopter should be much larger, enabling it to airlift large artillery pieces and possess enough internal space to carry the new MGM-31 "Pershing" missile system . During 1957, Vertol commenced work upon a new tandem-rotor helicopter, designated as the Vertol Model 107 or V-107. During June 1958, the U.S. Army awarded a contract to Vertol for the acquisition of a small number of
7068-442: The nose, five .50 in machine guns and two weapon pods on the sides that could carry either XM159B/XM159C 70 mm rocket launchers or 7.62 mm miniguns. They arrived in Vietnam in 1966, and they engaged in six months of operational testing at An Khê Army Airfield . They performed well in combat, but its high maintenance costs and demand for use in troop and cargo transport was stronger. Three ACH-47s were lost. One collided with
7161-702: The organization of the War Department. The board submitted its recommendations to the Chief of Staff on 18 October. These were that the technical services be continued, with the Transportation Corps made permanent, and that the Finance Department becoming an eighth technical service. The service commands would be abolished, and their functions transferred to the Armies. The ASF would also be abolished, and its staff sections transferred to
7254-441: The principal mover of the 155 mm M198 howitzer , plus 30 rounds of ammunition, and an 11-man crew. The CH-47D has advanced avionics, including Global Positioning System . Nearly all US Army CH-47Ds were converted from previous A, B, and C models, a total of 472 being converted. The last U.S. Army CH-47D built was delivered to the U.S. Army Reserve , located at Fort Hood, Texas , in 2002. The Netherlands acquired all seven of
7347-508: The rigorous, fast-paced training is known as the 10 (or 11) toughest days in the Army. About 15 percent of the class does not make it through the first day, dubbed Zero day, which includes a demanding obstacle course. More fail to make it past sling load testing in phase two. Ultimately, only about 45 percent pass. On the morning of graduation, students must complete a 19.3 km (12-mile) march with rucksack in under three hours before receiving their wings. Completion qualifies soldiers to wear
7440-404: The rotorcraft, giving it the YHC-1A designation. As ordered, the YHC-1A possessed the capacity to carry a maximum of 20 troops. Three underwent testing by the Army for deriving engineering and operational data. However, the YHC-1A was considered by many figures within the Army users to be too heavy for the assault role, while too light for the more general transport role. Accordingly, a decision
7533-482: The same airframe as earlier models, with more powerful engines. Early CH-47Ds were powered by two T55-L-712 engines. The most common engine is the later T55-GA-714A. With its triple-hook cargo system, the CH-47D can carry heavy payloads internally and up to 26,000 lb (12,000 kg) (such as 40-foot or 12-meter containers) externally. It was introduced into service in 1979. In air assault operations, it often serves as
7626-437: The school's 34-foot (10 m) tower, 9 to 12 rappels from the open side, and two rappels from a UH-60 Blackhawk helicopter hovering at 21–27 m (70–90 ft). All rappels are conducted with and without combat equipment. During fast rope familiarization, students conduct a controlled descent and a static hold for five seconds. Students that successfully conduct both descents from a 12-foot (3.7 m) platform then descend from
7719-616: The subsequent Operation Desert Storm in 1990–91. The CH-47D has seen wide use in Operation Enduring Freedom in Afghanistan and Operation Iraqi Freedom in Iraq. The Chinook is being used in air assault missions, inserting troops into fire bases , and later bringing food, water, and ammunition. It is also the casualty evacuation aircraft of choice in the British Armed Forces . In combat theaters , it
7812-413: The two dozen distribution centers and trucks, proving essential as trucks could not reach the worst hit areas due to downed trees and power lines. They flew everyday for approximately three weeks, moving supplies and personnel around the disaster zone as well as carrying media and government officials, including then Congressman Bill Nelson . Ultimately, the Chinooks supplied 64 distribution sites throughout
7905-476: The type began in 1974. Receiving the Canadian designation "CH-147", these were fitted with a power hoist above the crew door; other changes included a flight engineer station in the rear cabin: operators referred to the configuration as the "Super C". The CH-47C was used widely during the Vietnam War, eventually replacing the older Piasecki H-21 Shawnee in the combat assault support role. The CH-47D shares
7998-624: The type's inception, the Chinook has carried out various secondary missions, including medical evacuation, disaster relief, search and rescue, aircraft recovery, fire fighting, and heavy construction assistance. In February 2020, the Indian Air Force started using Chinooks at theatres such as Ladakh and Siachen Glacier to assist Indian forces deployed at the Indian borders with China and Pakistan . The Indian Space Research Organisation has also enlisted Indian Air Force Chinooks during
8091-473: The zone and transported 1.2 million pounds of supplies before the urgent relief phase ended. Three of Japan's CH-47s were used to cool Reactors 3 and 4 of the Fukushima Nuclear power plant following the 9.0 earthquake in 2011 ; they were used to collect sea water from the nearby ocean and drop it over the affected areas. In order to protect the crew from the heightened radiation levels present,
8184-478: Was also given the status of a "specified command", almost equal to a unified combatant command , with a broad and continuing mission, but composed solely of Army forces. Like the unified commands, the specified commands reported directly to the JCS instead of their respective service chiefs. Fourth Army cased its colors and was inactivated for the last time in 1991. FORSCOM lost its specified status in 1993. Sixth Army
8277-561: Was headquartered at the Presidio of San Francisco . It was eventually inactivated in June 1995. In 2004, Fifth Army transferred its Reserve Component preparation obligations to First Army, and became responsible for homeland defense and Defense Support of Civil Authorities (DSCA) as United States Army North, the Army Service Component Command of United States Northern Command . Following the recommendations of
8370-455: Was made to procure a heavier transport helicopter, and at the same time, upgrade the UH-1 "Huey" to serve as the needed tactical troop transport. The YHC-1A would be improved and adopted by the Marines as the CH-46 Sea Knight in 1962. As a result, the Army issued a new order to Vertol for an enlarged derivative of the V-107, known by internal company designation as the Model 114, which it gave
8463-750: Was one of the first major helicopter disaster relief operations on US soil. Then President George H. W. Bush ordered the military to assist. The Chinooks arrived at Miami-Opa Locka Executive Airport , just outside of the disaster zone, one day after the President's order; early on, they performed a wide loop over Homestead and Florida City to publicly display their presence, helping to curtail lawlessness and looting. The Chinooks initially flew twelve sorties per day out of Opa Locka, which expanded over time, often supporting distribution operations at Homestead AFB and Opa Locka, as well as delivering relief payloads via internal storage, not using sling loads, supplementing
8556-489: Was struck by an Exocet sea-skimming missile fired by an Argentine Super Étendard . The sole surviving British Chinook, Bravo November , did outstanding service in the Falklands, lifting 81 troops on one occasion. Since April 2022, it has been on display at Royal Air Force Museum Cosford . About 163 CH-47Ds of various operators were deployed to Saudi Arabia , Kuwait , and Iraq during Operation Desert Shield and
8649-572: Was unable to be recovered and was destroyed in place. To compensate for the loss, the ADF added two ex-U.S. Army CH-47Ds to the fleet which are expected to be in service until the introduction of the CH-47Fs in 2016. On 6 August 2011, a Chinook crashed near Kabul, killing all of the 38 aboard. The Chinook was reportedly shot down with a rocket-propelled grenade by the Taliban while attempting to assist
