The Phönix D.I / D.II / D.III was an Austro-Hungarian WWI fighter based on the Hansa-Brandenburg D.I. Only a few D.IIIs were completed before the end of the war. Sweden purchased 17 of these aircraft, called Phönix 222s. Ten more were built under licence by FVM here at Malmen in 1925-1926. In 1926 the type received the J1 designation for a fighter, although it was by then used only as a trainer.

Designed by Ernst Heinkel and first flown in 1914, the Albatros B.II was the main German reconnaissance aircraft early in WWI, despite the poor view for the observer who sat in the front cockpit. It was also an important trainer. One B.II was interned in Sweden at the outbreak of the war, and the design was copied and manufactured by several Swedish companies.
