Valmet and its predecessors

Four year after Finland (Suomi) became an independent nation in 1917, the Ilmailuvoimien Lentokonetehdas (Air Force Aircraft Factory, often abbreviated to I.V.L. or IVL) was established within the military fortress at Suomenlinna near Helsinki in April 1921. The first aircraft produced was the license-built Hansa-Brandenburg W.33, designated A.22. Thereafter prototypes of indigenous design and other license-built types were manufactured. In February 1928 the Ilmailuvoimien Lentokonetehdas changed into Valtion Lentokonetehdas (State Aircraft Factory, often abbreviated to V.L. or VL) and next to the works at Suomenlinna, another work was established in Santahamina. Again aircraft of indigenous design and license-built types were manufactured, the Fokker D.XXI topping with 90 produced. In 1935 Valtion Lentokonetehdas was reorganized, works at Suomenlinna and Santahamina were closed and all design and production work was moved to Tampere. In 1940 a second factory was opened at Kuorevesi, three years later a third was opened at Linnavuori. After the war ended in 1945 Valtion Lentokonetehdas and other state owned factories were united in Valtion Metallitehtaat Lentokonetehdas (State Metal Factories, often abbreviated to V.M.T. or VMT). A diversified number of product were manufactured, from motors to sewing machines. It was not until 1951 that the next aircraft design was flown. That year Valtion Metallitehtaat Lentokonetehdas was re-named Valmet OY Lentokonetehdas (Valmet Aircraft Factory) with subsidiaries Valmet Oy Tampereen tehdas ja Kuoreveden tehdas (Valmet Oy Tampere works and Kuorevesi works). In 1963 Karhumäki works at Kuorevesi became part of Valmet. Its main business was maintenance work for the Ilmavoimat (Finnish AF). In 1967 Valmet moved all aviation activities to Kuorevesi. In 1974 Valmet OY Lentokonetehdas was renamed Valmet Lentokonetehtaan (Valmet Aviation Industries). In 1989 Valmet Lentokonetehtaan was renamed Valmet Lentokoneteollisuus (Valmet Aircraft Industries). On September 5, 1996 Valmet became Patria Finavitec Oy. The tables below show only the flown aircraft.
