American lightweight twin-engined aircraft, produced in the mid-1960s by the Cessna company and based on a civil version of the Type 337. It differed from conventional layouts in having fore-and-aft engines in the fuselage and a twin boom construction. Upon the outbreak of the Vietnam War, it was widely used as a communications and special missions aircraft, including a role marking targets for other heavier attack planes; and also as a rescue plane, with the purpose of evacuating pilots of damaged aircraft from enemy territory. In total, 532 airplanes of this type were produced, the combat service of which continued after the end of the Vietnam War, but only in communications and patrol tasks. Today, this aircraft is highly desired by private owners, not only in the United States but also in many countries around the world.
