The Hispano HA-200 Saeta (English: Arrow) was a twin-seat jet advanced trainer designed and produced by Spanish aircraft manufacturer Hispano Aviación. It has the distinction of being the first Spanish aircraft to harness jet propulsion.
The German aircraft designer Willy Messerschmitt can be largely credited for his role in designing the HA-200, which reused a substantial portion of the earlier piston-powered HA-100 Triana. On 12 August 1955, the first prototype conducted its maiden flight. It was not until 1962 that the first production aircraft performed its first flight. That same year, deliveries of the trainer aircraft commenced to the Spanish Air Force. It would be used in this capacity by the service for multiple decades.
The HA-200 was later further developed into the Hispano Aviación Ha-220 "Super Saeta", which functioned as a dedicated ground attack platform, armed with rockets, bombs, and other munitions. The HA-220 served in the Spanish Air Force throughout the 1970s, seeing action during the Polisario uprisings against insurgents. The HA-200 was also exported, the type being produced under license by Egypt, where it was designated as the Helwan HA-200B Al-Kahira. During the 1980s, the more capable CASA C-101 was introduced to Spanish service, supplementing and eventually succeeding the older HA-200 in both trainer and light attack roles.
Development
Background
The origins of the HA-200 Saeta are heavily intertwined with the German aircraft designer Willy Messerschmitt, who was responsible for producing a significant proportion of its design. Following the end of the Second World War, Messerschmitt emigrated from Germany and begun offering his services to various other nations, including South Africa. During 1951, he had settled in Francoist Spain and shortly thereafter begun to design aircraft for the government in conjunction with local aircraft manufacturer Hispano Aviación. During the early 1950s, Messerschmitt worked on the HA-100 Triana, a piston-powered prototype trainer aircraft; while never attaining production, this design would subsequently serve as the basis for the HA-200. In fact, the two aircraft directly shared many design features, including the wing, tail unit, and tricycle undercarriage; original elements were largely confined to the area forward of the cockpit.
As early as 1951, Messerschmitt had promoted the idea of Spain developing its independent aviation industry, as well as suggesting the pursuit of both an indigenous jet fighter and jet engine. Throughout the 1950s, progress on the HA-200 programme was supervised by Messerschmitt from Hispano's office in Seville. It would be Spain's first indigenously-developed aircraft to be powered by the turbojet engine. On 12 August 1955, the first prototype conducted its maiden flight, flown by Major Fernando de Juan Valiente, the company's chief test pilot. Valiente later praised the prototype's handling qualities, stating them to be light and responsive, including "viceless and straightforward" stall characteristics.
Early on, the French Turbomeca Marboré turbojet engine had been selected to power the type; Spain had successfully negotiated a license to locally produce this engine. Development was protracted, the first production aircraft, which was designated by the manufacturer as HA-200A, first flew during October 1962. Shortly thereafter, the initial version of the aircraft were delivered to the Spanish Air Force; in service, it was operated under the service designation E.14.
Further development
The initial trainer model of the aircraft was shortly followed on by a single-seat version, designated as the HA-220, which was designed to perform ground attack missions. On 25 April 1970, this new model made its first flight. During the early 1970s, the ground attack-orientated HA-220 entered into service with the Spanish Air Force, which designated the type as C.10. It remained in service for barely a decade, all of the C.10s being withdrawn from Spanish service by the end of 1981.
