At the oubreak of the Russo-Finnish War, the situation of the military aviation in the small nordic country was rather critical, for it was in a condition of total dependency on the war industry of the nations which, in that occasion, supported Finland. Two years later, when the army of Marshal Mannerheim thought of paying the Red Army back in its own coin, the situation had significantly changed, both qualitatively and quantitatively, but the uncomfortable and disturbing basic situation remained. The ranks of the Finnish Air Force comprised German and Italian aircraft provided by the two main allies of the country, as well as many British, French, Dutch, American and - surprisingly - Russian aircraft. It is true that the Valtion Lentokonetehdas (the state-owned aircraft factory, which represented almost all of the whole aeronautical industry) had been producing for some time, under licence, the Dutch Fokker D XXI fighter aircraft and the British Bristol Blenheim bomber aircraft, but the absence of a model designed around parameters which were characteristic of that war theater was increasingly noticeable. Because of that in 1941 it was decided to try the production of a national model, and the order was entrusted to engineer Edward Vegeluis, from the Valtion Lentokonetehdas (VL). The prototype, denominated Myrsky (Storm), flew for the first time in the early 1942. It was undoubtedly not a fully sucessful creation, for it presented significant inconveniences, such as a certain structural weakness, unstability during flight and the ugly tendency of losing the coating of the fuselage when the aircraft was in full effort. Out of this first aircraft four exemplars were built, which were soon returned to the factory for studying adequate modifications which could correct their defects. From this restructuring of the aircraft the Myrsky II, of which 46 exemplars were built, was born. But these entered service too late for being used effectively against the Russians, and because of that they were used, but only in a symbolic manner, against the retreating Wehrmacht, as imposed by the clauses stipulated in the armistice signed between Finland and the Soviet Union. Structurally, the Myrsky was a low-wing monoplane single-engine aircraft fitted with a retractable landing gear. The body was one of mixed construction (metallic in the framework of the fuselage and wooden in that of the wings). The coating was a plywood one in the rear part and a metallic one in the fore part. The engine was a Pratt and Whitney Twin Wasp R-1830-SC3-G 14-cylinder radial engine, which was acquired in Sweden, where the SFA company produced it under American licence. The armament comprised four Browning 12.7-millimeter machine guns which fired through the propeller disc area. In overall, the Myrsky was barely used during war operations, and despite the modifications it was an aircraft of not very bright characteristics, to the point that it did not enjoy a great popularity among the pilots. The importance of this aircraft lies mainly in the fact that it was the first aircraft which was entirely produced in Finland, where it served as a test bench for the incipient aeronautical industry of this country. This one, from the basis of the experience acquired with the Myrsky, would shortly after produce the Pyorremyrsky (Whirlwind), a fighter-bomber aircraft which could have showed itself as an excellent aircraft if the course of the war had allowed a full development of it.
