Design

Even though Sweden was neutral, it had to defend itself as there was fighting all around it. Unable to bring in American fighters Sweden decided to design and produce them on their own. The government owned Flygforvaltningens Flygverkstad (Air board workshop) or FFVS was setup at Ulvsunda. The FFVS J 22 was a result of this need.

The design work on the F.F.V.S. J 22 started on January 1, 1941.

The J 22 was made of a steel frame and wood construction.

Engine

The engine was an unlicensed copy of the Pratt & Whitney R-1830-SC-3-G Twin Wasp. Later a license was purchased.

Prototype

The J 22 prototype flew for the first time on September 21, 1942 / September 1942.

Production

An order, straight from the drawing board, for 60 was placed in 1941. Production went until April 1946.

  • Prototypes: 2
  • F.F.V.S. J 22A and F.F.V.S. J22 B: 198
  • Total: 200
    • Manufacturer: F.F.V.S.

Variants

  • F.F.V.S. J 22A: First flew in September 1943.
  • F.F.V.S. J 22B:

Usage

Deliveries of the J 22 started in November 1943. The J 22 eventually equipped seven wings. They remained in service until 1952 when they were replaced by the de Havilland Vampire jet fighter.
