A fighter aircraft is a military aircraft designed primarily for air-to-air combat with other aircraft, as opposed to a bomber, which is designed primarily to attack ground targets by dropping bombs. Fighters are small, fast, and maneuverable. Many fighters have secondary ground-attack capabilities, and some are dual-roled as fighter-bombers; the term "fighter" is also sometimes used colloquially for dedicated ground-attack aircraft. Fighter aircraft are the primary means by which armed forces gain air superiority over their opponents in battle. Since at least World War II, achieving and maintaining air superiority has been a key component of victory in warfare, particularly conventional warfare between regular armies (as opposed toguerrilla warfare). The purchase, training and maintenance of a fighter fleet represent a very substantial proportion of defense budgets for modern militaries.
