Hispano HA-200

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.

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.

During the late 1950s, the emerging HA-200 had drawn the attention of Egyptian President Gamal Abdel Nasser; around this time, Nasser was passionate on the subject of developing Egyptian industrial and military capabilities alike, which included the domestic production of modern jet aircraft. Negotiations between Spain and Egypt were facilitated by Messerschmitt, who acted as a key go-between for the two parties. During 1959, an arrangement was reached that led to the HA-200 being produced under license in Egypt at the Helwan Air Works. Hispano provided documentation pertaining to the aircraft's design and manufacture to support these efforts. Both the airframe and the engines were locally manufactured. According to aerospace periodical Flight International, a total of 65 HA-200s were reportedly constructed at Helwan between 1960 and 1969. In Egyptian Air Force service, the type was commonly referred to as the Helwan HA-200B Al-Kahira.

According to Flight International, during the early 1960s, Egypt and Spain were collaborating on the development of a six-seater business jet directly derived from the HA-200. Around this time, the two nations jointly worked on various aviation projects, including the Helwan HA-300, a cancelled supersonic fighter aircraft.

Design
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.

Operational history
In 1970, the HA-200 replaced the aging CASA 2.111 (a Spanish development of the Heinkel He 111) in Escuadrón 462 on the Canary Islands. From there, they frequently flew on detachments to Spanish Sahara.

Late in 1974, during the Polisario uprisings, the HA-200 conducted its first combat missions against the Polisario Front. In one instance, guerillas ambushed a police patrol from higher ground and caves, keeping them pinned from their protected positions. In response, several T-6D fighters and UH-1 helicopters strafed the Polisario positions with machine gun fire, but had little effect; additional air strikes by a pair of Saetas, armed with 2.75-inch FFARs, were more successful. Diving at a 45-degree angle at the cave entrances, the HA-200's qualities proved itself most suitable for the role. Following these rocket attacks, ground troops attempted to take the caves but were pushed back.

The next morning, the Saetas returned to perform more air strikes in the company of more T-6s and UH-1 troop carriers. The attack pattern was repeated with success again, aided by a Forward Air Controller that directed ground fire to where it would be most effective. Multiple rockets entered the caves through the 5–10 foot entrances, few reported missed their target. It is believed that one of the rockets set off some stored mortar rounds, as there were several large explosions. Afterwards, ground troops advanced upon the caves again, this time facing hardly any resistance as most of the guerillas had been killed by the rockets from the Saetas.
