Lohner B.IV

Lohner rebuilt one of the Lohner B.IIIs with new wings, undercarriage, and engine as the Series 15 or Type G. Its career was brief: it was accepted on June 1915 and written-off in August.

UFAG built eight Lohner B.IV(U) (Series 15.5). They saw brief service before becoming training aircraft.
