The FFVS J 22 was a Swedish single-engine fighter aircraft developed for the Swedish Air Force during World War II.
At the onset of World War II, the Swedish Air Force (Flygvapnet) was equipped with largely obsolete Gloster Gladiator (J 8) biplane fighters. To augment this, Sweden ordered 120 Seversky P-35 (J 9) and 144 P-66 Vanguard (J 10) aircraft from the United States. However, on 18 June 1940 after the German occupation of Norway, the United States declared an embargo against exporting weapons to any nation other than Great Britain. As the result, Flygvapnet suddenly faced a shortage of modern fighters. Several other foreign alternatives were considered: the Finnish VL Myrsky and Soviet Polikarpov I-16 were unsatisfactory, and while the Mitsubishi A6M Zero was available, delivery from Japan was impractical. A batch of Fiat CR.42 Falco (J 11) biplanes and Reggiane Re.2000 Falco (J 20) were eventually purchased but this was clearly an interim solution.
With Flygvapnet facing a serious shortage of aircraft and Saab running at full capacity building its single-engine Saab 17 and twin-engined Saab 18 bombers, a new firm and factory were established specifically for the new fighter — Kungliga Flygförvaltningens Flygverkstad i Stockholm ("Royal Air Administration Aircraft Factory in Stockholm", FFVS) under Bo Lundberg. The aircraft, designated J 22, was a monoplane with a plywood-covered steel airframe. Wing and fuselage layout were conventional, with the narrow-track main landing gear retracting rearward entirely within the fuselage, somewhat similar to the 1935 Focke-Wulf Fw 159 parasol-wing monoplane fighter design. Power came from a Swedish copy of the Pratt & Whitney R-1830 Twin Wasp, manufactured without a license at the time, though license fees were paid later (a symbolic US$1).
