An attack helicopter is an armed helicopter with the primary role of an attack aircraft, with the capability of engaging targets on the ground, such as enemy infantry and armoured fighting vehicles. Due to their heavy armament they are sometimes called helicopter gunships.
Weapons used on attack helicopters can include auto-cannons, machine guns, rockets, and guided anti-tank missiles such as the Hellfire. Many attack helicopters are also capable of carrying air-to-air missiles, though mostly for purposes of self-defence. Today's attack helicopter has two main roles: first, to provide direct and accurate close air support for ground troops, and second, the anti-tank role to destroy enemy armour concentrations. Attack helicopters are also used to supplement lighter helicopters in the armed scout role. In combat, an attack helicopter is projected to destroy around 17 times its own production cost before it is destroyed
A helicopter is a type of rotor-craft in which lift and thrust are supplied by rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward, and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of VTOL (vertical takeoff and landing) aircraft cannot perform. English language nicknames for helicopter include "chopper", "copter", "helo", "heli", and "whirlybird".
Helicopters were developed and built during the first half-century of flight, with the Focke-Wulf Fw 61 being the first operational helicopter in 1936. Some helicopters reached limited production, but it was not until 1942 that a helicopter designed by Igor Sikorsky reached full-scale production, with 131 aircraft built. Though most earlier designs used more than one main rotor, it is the single main rotor with anti-torque tail rotor configuration that has become the most common helicopter configuration. Tandem rotor helicopters are also in widespread use due to their greater payload capacity. Coaxial helicopters, tilt rotor aircraft, and compound helicopters are all flying today. Quad copter helicopters pioneered as early as 1907 in France, and other types of multi copter have been developed for specialised applications such as unmanned drones.
