LFG D.I

The LFG Roland D.I was a German fighter designed by Luft-Fahrzeug-Gesellschaft (LFG) during World War I. It was a single-seat aircraft based originally on the Roland C.II two-seat reconnaissance type. It shared its predecessor's unusual design feature of having a deep fuselage that completely filled the interplane gap, but in comparison, the fuselage was much sleeker. While the C.II's appearance had earned the Walfisch ("Whale"), the D.I became known as the Haifisch ("Shark"). The I-struts that had been used to brace the C.II's wing were replaced by more conventional struts. Other changes to the wing included the removal of stagger from the design and the introduction of slight sweepback.
