А.Шепс Самолеты Первой мировой войны. Страны Антанты
S.V.A.5 1917 г.
Одновременно с истребителем A-1 "Балилла" фирма выпустила под обозначением S.V.A ("Савойя Вердуццио Ансальдо" - филиал фирмы) серию разведчиков и легких бомбардировщиков, имевших аналогичную конструкцию и даже внешне похожих на него. Отличались они только большими размерами и увеличенным размахом крыла. Машины выпускались как одноместные, так и двух- и трехместные, что вело к изменению конструкции кабины.
Устанавливались различные варианты вооружения. Машины строились как в ходе войны, так и после ее окончания и поставлялись в ряд европейских и латиноамериканских стран.

L.Andersson Soviet Aircraft and Aviation 1917-1941 (Putnam)
Ansaldo A 300/3
The Ansaldo A 300 reconnaissance and light bombing aircraft, a heavier and more powerful type than the earlier SVA models, was first flown in 1919. It was a two-bay biplane of normal wooden construction powered by a 300hp Fiat A 12bis engine. It had equal-span wings with unbalanced ailerons and a normal undercarriage. The A 300/2 was a two-seat version, while the A 300/3 had provision for a crew of three; pilot, gunner and observer. Armament consisted of a single machine-gun mounted in the rear cockpit. The A 300/4 model was adopted by the Italian Air Force as its standard reconnaissance type and a total of 612 were delivered from 1924/ 25. Most Italian reconnaissance units converted to the A 300 but apparently the Regia Aeronautica was not completely satisfied with this aircraft and it was replaced by other types after only a short period of service. About one hundred were converted to the A 300/6 with 410hp Fiat A 20 engines by the Gabardini company.
Exports of the A 300 were made to the military air services of Belgium, China, Hungary (just a few), Mexico (one), Poland, Spain, the Soviet Union and Turkey (one). A substantial number of A 300s were built under licence in Poland, but the large-scale production contracts placed were soon cancelled and the Service career of the Polish A 300s was plagued by engine fires and structural failures.
The Soviet order for Ansaldo aircraft placed in 1922 was to have included fifty examples of the A 300/3 three-seat version, but the number of aircraft ordered was eventually reduced to thirty (c/ns 7066-7095). The first consignment of sixteen SVA 10s and four A 300 aircraft was shipped to Odessa on board the Patras in April 1922 and by June all A 300s had arrived. The Ansaldo test pilot Botalla and three fitters assembled and test-flew the Italian aircraft at Odessa and in Moscow. The A 300s were assigned to the 1st Razvedivatel'naya eskadril'ya of the Aviatsionnaya Eskadra No. 2 at Kiev. This unit became the 3rd Otdel'naya razvedivatel'naya aviatsionnaya eskadril'ya in 1924. The NOA, the 1st Higher School of Pilots and the Higher School of Observers also had single examples of the A 300/3 and three were assigned to the Academv of the VVS in 1925.
In 1925 the A 300s of the 3rd Otdel'naya razvedivatel'naya aviaeskadril'ya at Kiev were replaced by R-1s and passed on to the 14th and 17th Korpusnye aviaotryady, also at Kiev, and other units. In the spring of 1926 the A 300 was tested with the 250hp BMW IV engine and at least eighteen were converted to two-seat A 250/2s with this engine in 1926-27. From 1927 the Ansaldos were serving with the 17th and 37th Aviaotryady, also at Kiev, but they were finally replaced by R-ls in 1928. Relegated to the advanced training role they passed to the 2nd Combined School of Military Pilots and Mechanics at Vol'sk.
In November 1927 Dobrolet and Ukrvozdukhput had been offered six to eight Ansaldos each, but there was no requirement for aircraft of this type in civil aviation. By the end of 1929 eighteen Ansaldos remained. All but two were written off in 1930 and the last disappeared during the following year.
