Sweden's FFVS J 22 fighter1
FFVS J 22 fighter:
Design
Even though Sweden was neutral, it had to defend itself as there was fighting all around it.1 Unable to bring in American fighters Sweden decided to design and produce them on their own.1 The government owned Flygforvaltningens Flygverkstad (Air board workshop) or FFVS was setup at Ulvsunda.1 The FFVS J 22 was a result of this need.1
The J 22 was made of a steel frame and wood construction.1
Engine
The engine was an unlicensed copy of the Pratt & Whitney R-1830-SC-3-G Twin Wasp.1 Later a license was purchased.1
Prototype
The J 22 prototype flew for the first time on September 21, 1942.1
Production
An order, straight from the drawing board, for 60 was placed in 1941.1 Production went until April 1946.1
- Prototypes: 21
