The O-maskinen was designed and built by Flyvetroppernes Værksteder (The Flying Corps’ Toolshops). There were two models of the O-Maskine. I O and II O. I O was a two-seater biplane designed and test-flown during 1926, and the II O was a single-seater. They were mainly used for training purposes, but they could be armed with one fixed and two movable 8mm Madsen machine guns. O-maskinen was painted white and grey except for a brief period before WWII, where the standard Danish Army camouflage colours were used.
The table below shows the specifications.
