An attack helicopter is an armed helicopter with the primary role of an attack aircraft, with an offensive capability to engage ground targets such as enemy infantry, military vehicles and fortifications.

Because of their heavy armament, they are sometimes called gunship helicopters.

Attack helicopters can use weapons such as automatic cannons, machine guns, rockets and anti-tank missiles such as the AGM-114 Hellfire.

Some attack helicopters are also capable of carrying air-to-air missiles for self-defence against other helicopters and low-flying light combat aircraft.
