L.V.G. D V
Another 195 h.p. Benz-powered prototype, the D V of 1918 reverted to a slab-sided ply-covered fuselage. Most singular feature was the juxtapositioning of the wing surfaces, the lower one being of much broader chord, and the main lifting surface. The narrow-chord upper-wing panels pivoted differentially outboard of the centre-section, the entire surface of both wings acting as "ailerons" to provide lateral manoeuvre.
L.V.G. D VI
Final fighter to emerge from the L.V.G. stable was this aggressive-looking D VI. It had many unique features: chin-type radiator air intake, swept lower wing, metal strap bracing, "I"-type interplane struts and a lifting surface on the axle as featured on Fokker aircraft. The almond-shaped rudder was pivoted on a tubular spar, and would appear to have been a highly vulnerable assembly. Engine, 195 h.p. Benz Bz IIIb.

L.V.G. Scout. D.V. Type.
In this L.V.G. the streamlining embraces both the interplane and plane-cum-fuselage connectiong twin-struts, of more or less V structure. The inner set is provided with a round cutting in the streamlining. The steepness, though not markedly whale type, camouflaged body of the L.V.G. may be result of the employment of a powerful stationary motor. The chord of the lower plane of the L.V.G. looks large for a scout; the rudder asks for comment. Considering the large impulses on a scout rudder from hard work the unsupported position seems daring. The hinged fixed plane and elevator position of the L.V.G. Scout is that of the Brandenburg seaplane faschion.

LVG D V Germany
Designed by Paul Ehrhardt and flown for the first time in June 1918, the LVG D V was unusual in that the lower wing was of much broader chord than the upper. The narrow-chord upper wing panels outboard of the centre section pivoted differentially to act as "ailerons” for lateral manoeuvres. The fuselage was slab-sided and plywood covered, armament comprised two 7,9-mm LMG 08/15 machine guns and power was provided by a geared Vee-eight Benz Bz IIIbm engine affording 185 hp. The D V proved fast, but it was unstable at full speed and its controllability was poor. During a test flight with Ehrhardt at the controls in July 1918, the sole D V prototype made a crash landing and turned turtle, further development being halted. No data are available on this type.
LVG D VI Germany
The last single-seat fighter to emerge from LVG, the D VI single-bay biplane was in final assembly in September 1918, flight testing being initiated shortly before hostilities terminated. Like the preceding D V, it featured a slab-sided plywood-covered fuselage, a twin-LMG 08/15 gun armament and a 185 hp Benz Bz IIIbm geared Vee-eight engine with a chin-type air intake. However, the wing configuration was totally different, the lower wing being sweptback and the I-type interplane struts being supplemented by metal strap cross bracing. No data relating to the D VI are available.
