Development was the result of a need for a heavy lift helicopter capable of carrying major missile components and dropping them into silos without the benefit of road infrastructure.[clarification needed] Production began on the V-12 prototype in 1965 with the goal of lifting no less than 30,000 kg (~33 short tons).
The first prototype made its first lift-off on 27 June 1967. After a few oscillations in close proximity to the ground the V-12 made a rough touchdown on one wheel, resulting in a burst tire and a bent wheel disk. Even though the damage was insignificant, it was reported in the Western press that the prototype had suffered severe damage, and even to this day the rumor persists that the prototype had crashed fatally.
The Boeing CH-47 Chinook is an American twin-engine, tandem rotor heavy-lift helicopter. Its primary roles are troop movement, artillery emplacement and battlefield resupply. It has a wide loading ramp at the rear of the fuselage and three external-cargo hooks. With a top speed of 170 knots (196 mph, 315 km/h) the helicopter is faster than contemporary utility and attack helicopters of the 1960s. The CH-47 is among the heaviest lifting Western helicopters. Its name is from the Native American Chinook people.
The Chinook was designed and initially produced by Boeing Vertol in the early 1960s; it is now produced by Boeing Rotorcraft Systems. It is one of the few aircraft of that era -- along with the fixed-wing Lockheed C-130 Hercules cargo aircraft -- that remain in production and front-line service, with over 1,179 built to date. The helicopter has been sold to 16 nations with the U.S. Army and the Royal Air Force (see Boeing Chinook (UK variants)) its largest users.
The United States Army (USA) is the main branch of the United States Armed Forces responsible for land-based military operations. It is the largest and oldest established branch of the U.S. military, and is one of seven U.S. uniformed services. The modern army has its roots in the Continental Army which was formed on 14 June 1775, to meet the demands of the American Revolutionary War before the establishment of the United States. The Congress of the Confederation officially created the United States Army on 3 June 1784 after the end of the Revolutionary War to replace the disbanded Continental Army. The army considers itself to be descended from the Continental Army and thus dates its inception from the origins of that force.
The Armed Forces of the Russian Federation (Russian: Вооружённые Си́лы Росси́йской Федера́ции, tr. Vooruzhonnije Síly Rossíyskoj Federátsii) are the military services of Russia, established after the dissolution of the Soviet Union. On 7 May 1992, Boris Yeltsin signed a presidential decree establishing the Russian Ministry of Defence and placing all Soviet Armed Forces troops on the territory of the RSFSR under Russian control. The commander-in-chief of the armed forces is the president of Russia. Although the Russian armed forces were formed in 1992, the Russian military dates its roots back to the times of the Kievan Rus'.
The number of troops is specified by decree of the President of Russia. On 1 January 2008, a number of 2,019,629 units, including military of 1,134,800 units, was set. In 2010 the International Institute for Strategic Studies (IISS) estimated that the Russian Armed Forces numbered about 1,040,000 active troops and in the region of 2,035,000 reserves, (largely ex-conscripts) but a significant military reform is underway which will cut the number of active troops.
