The Convair 880 (CV-880) was one of the first jetliners. It was designed to compete with the British De Havilland Comet and Avro Canada C102 Jetliner. It faced competition against the Boeing 707 and Douglas DC-8, as well as the Soviet Tupolev Tu-104. A aerial refueling tanker variant was developed, the Convair UC-880, used by the U.S. Navy. A further development of the 880 was the CV-990 Coronado.
