IVL D.26 Haukka I (Hawk) was the Finnish competitor to equip the small fighter force, the sole D.26 (HA-39) illustrated after the trials at Utti in March 1928. The flying characteristics left a lot to be desired and the poor visibility made it unsuitable for a fighter role. The only modern element was the wooden monocoque fuselage structure.
