The Hispano HA-200 Saeta (English: Arrow) is 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. The HA-200 Saeta is a jet-powered trainer aircraft. In terms of its configuration, it is a low-winged monoplane, featuring all-metal construction and a retractable tricycle undercarriage arrangement. Structurally, it was relatively conventional for the era, using semi-monocoque lightweight alloy construction. The cockpit of the HA-200 accommodated a crew of two in a tandem seating configuration; however, the ground-attack orientated HA-220 was furnished with a single-seat cockpit instead. For greater crew comfort, this cockpit was pressurised, the HA-200 being the first Spanish aircraft to possess this facility. The HA-200's propulsion consisted of a pair of Turbomeca Marboré turbojet engines, which were installed in a side-by-side arrangement inside the forward fuselage and mounted on a stressed-skin structure that forms the outer surface of the fuselage's underside. Air was fed to the engines via a large intake on the front of the nose; this particular intake arrangement has been described as being unique amongst jet aircraft. The engine's exhaust nozzles were located upon the lower fuselage, just aft of the trailing edge of the wing. A maximum of 261 gallons of fuel could be carried across a pair of fuselage tanks, two wing tanks and two permanently-attached tip tanks; provisions were made for jettisoning fuel in emergency situations. For weapons training purposes, the HA-200 featured provisions for the carriage of armaments. For more details of development, operational history and 10 varients, click here.
