Initially an upgrade variant of the Model 19 A1, it progressed through a series of changes significant enough to create a different variant. Using the uprated K-1700-10 engine it had just developed, along with other changes to the cooling system meant that it doesn't require an additional liquid cooling system it had borrowed from the A1. Along with other advances from other nations regarding fighter aircraft, strengthening of the airframe along with modifying the cowling borrowed from another SwnAC aircraft model had become alternatives to improvement. The undercarriage was also altered but had the side effect of creating more drag than the previous iteration as it protruded down and forwards
