VL Myrsky II1
Finland's VL Myrsky fighter

Design

Design of the VL Myrsky first started in the middle of 1939.1 There were many initial problems that had to be ironed out before the Myrsky II was produced.1

The wing of the Myrsky was made of wood and the fuselage steel tubing.1 These were then covered with dural and fabric.1

Engine

The Swedes built the Pratt & Whitney Twin Wasp engine.1

Prototype

The Myrsky prototype was first flown on December 23, 1941.1 Problems were discovered in the design and three more prototypes / pre production aircraft were constructed.1 These underwent structural and other changes.1 The first to fly was in April 1943 and it crashed three weeks later.1 The second did a wheels up landing, but crashed after repairs.1 The third's wings detached during a dive.1
