The Lohner B. I was a military reconnaissance aircraft produced in Austria-Hungary during World War I. As Lohner strove to perfect the design a variety of increasingly powerful engines were fitted reflected in a range of military designations from B. II through to B. VI until the definitive B. VII was finally produced. This last version was also produced in an armed variant designated the C.I. The B.
