The Jaktfalk II was an improved version of the J6A and was available with the Armstrong Siddeley Jaguar or Panther engines,or the Bristol Jupiter.The Jaktfalk II retained the revised wing structure and lengthened fuselage of the J6A,to which were added redesigned horizontal tail surfaces from which the bracing struts were eliminated.
Seven aircraft were ordered by Flygvapnet powered by the supercharged nine-cylinder Bristol Jupiter VIIF radial engine rated at 520hp at 10,000ft(3050m).Armament comprised the standard paired 8mm machine guns synchronised to fire through the propeller blades.The contract was placed with ASJA on 1 May 1933 and the seven aircraft were delivered during the following October-November serving,like the Svenska Aero-built J6s and J6As,with Flygflottilj1 at Vasteras.Two of the J6B Jaktfalkar together with a single Svenska Aero-built J6A were donated to Finland in December 1939 and went on to serve in the fighter training role.
