A
cargo aircraft (also known as
freight aircraft,
freighter,
airlifter or
cargo jet) is a
fixed-wing aircraft that is designed or converted for the carriage of
air cargo, rather than passengers. Such aircraft usually do not incorporate passenger amenities, and generally feature one or more large doors for loading cargo. Freighters may be operated by civil passenger or
cargo airlines, by private individuals or by the
armed forces of individual countries (for the latter see
military transport aircraft).
