    Just under 200 examples of the FFVS J22 single-seat fighter were built for the Swedish Air Force from 1942 to 1946.

    When another World War broke out in Europe in September of 1939, European powers scattered about to find viable, modern weapons. This proved the case with Sweden - remaining neutral for the duration of the grand conflict - as it sought to strengthen its outdated stock of fighter aircraft. There were short-term solutions to be had in securing several American designs and additional warplanes arrived through agreements with Italy but a better long-term design was needed as acquiring foreign types soon proved impractical - if not impossible - in the growing war commitment.

    This led Swedish authorities to establish an all new production facility which would manufacture a new design of local origin - the "J22". The factory was given the label of Kungliga Flygforvaltningens Flygverkstad i Stockholm under the acronym of "FFVS" and design work was headed by Bo Lundberg.

    The result was a single-seat, single-engine fighter with all-modern qualities - an enclosed framed cockpit, monoplane wings, retractable undercarriage, etc... Construction incorporated a steel understructure with plywood skinning. On the whole, the design was very traditional for the period as the nose carried the engine installation and aft of this was the cockpit with the fuselage tapering to the rear and holding a single-finned tail unit. The wing mainplanes were low-mounted appendages and straight in their general shape with clipped tips. An unlicensed Pratt & Whitney R-1830 "Twin Wasp" engine (the SFA STWC-3G 14-cylinder air-cooled radial) was selected to power the type and produced 1,065 horsepower while driving a three-bladed propeller unit (a large aerodynamic spinner was fitted to this). Armament was 2 x 13.2mm heavy machine guns coupled with 2 x 7.9mm medium machine guns.
