For our first Italian subject in the DATAFILE series the Ansaldo SVA 5 was the obvious choice and the combined talents of some of Italy's best known aviation historians and enthusiasts has resulted in a unique contribution to WW1 aeronautical literature. Many aspects of the type, and its derivatives, appear here — for the first time in any language — and will prove invaluable to enthusiasts, the Ansaldo being deservedly popular as a colourful subject for scale modelling. With rare archive photographs, carefully-researched scale drawings and accurate colour notes, Gregory Alegi traces the development and service career of this distinctive and successful combat aeroplane.
In 1915-1916 the Italian industry completed 1637 aircraft, of which only 168, all Caproni bombers of various models, were of indigenous design. To free Italy from its dependency on foreign technology, in mid-1916 Capitani Umberto Savoja and Rofolfo Verduzio, two engineers serving in Turin with the Direzione Tecnica dell'Aviazione Militare (DTAM), began working on a new project which, with the consent of Maggiore Ottavio Ricaldoni, was concealed as a study for a 100 hp training biplane. Savoia and Verduzio were aided by Tenente ingegner Celestino Rosatelli who - although initially assigned to oversee the two draughtsmen - eventually calculated the aircraft and, 'designed it in construction form(1) Following Italian practice, the aeroplane was named SV after Savoja and Verduzio.
The SV abandoned the twin-tail boom and nacelle configuration of the Caudrons, Farmans and Voisins being built in Turin in favour of a modern fuselage design, in part inspired by examination of the wreck of an Austro-Hungarian aeroplane/2-* Given the shortage in Italy of vital aviation materials, including high-grade steel, spruce, fabric and dope, Savoja and Verduzio strove to produce an aircraft that achieved strength by design rather than by materials. From this concept stemmed the rigid truss, plywood-covered fuselage and Warren-trussed wings.
