Valmet Vihuri (Finnish for Gale) was a Finnish advanced two-seat fighter trainer aircraft, serving in the Finnish Air Force between 1953 and 1959.In spite of their economical problems, the aircraft manufacturer Valmet began designing a new aircraft in the beginning of the 1950s, to replace the aging FAF VL Pyrys. Martti Vainio was the chief designer of the project. Most of the planning was made by the aeronautic engineers L. Hamalainen and T. Mantysalo in 1948–49. The Bristol Mercury was chosen as the engine, since there were no other alternatives. The Mercury was license made in Finland for the Bristol Blenheim bomber. The prototype (VH-1) made its first flight on February 6, 1951 in Tampere, piloted by captain Esko Halme. After the successful test flights, the FAF ordered 30 aircraft of the production series, called Valmet Vihuri II on February 27 1951. In the autumn of 1954, the air force ordered a further 20 aircraft of the developed version Valmet Vihuri III. All the aircraft of the third version were handed over to the air force on January 15, 1957.
