[edit] Versions
- IVL D.26 Haukka I - the first prototype aircraft, which made its maiden flight on March 17, 1927. Only one aircraft was manufactured.
- VL D.27 Haukka II - a further developed version of the D.26. Two aircraft were manufactured at the aircraft factory at Suomenlinna (which now had shortened its name from IVL to VL). These aircraft were used by the Finnish Air Force in its Maalentoeskaadri for a couple of years. During this time the FAF had begun the purchasing of foreign fighters, which eventually halted the series production of the Haukka II.
[edit] Museum aircraft
Two Haukkas are preserved, one D.26 at Päijät-Häme Aviation museum and one D.27 at Hallinportti Aviation museum.
