The LWF model V[note 1] is an American two-seat reconnaissance and training biplane built during World War One, and used for a short period afterwards.

[1] Both undercarriage and empennage were conventional for the period, with fore and aft vees connected laterally with the axle and a spreader bar.

[1] A modified variant of the V, the F, was the first aircraft to fly with the new Liberty L-12 engine that would find widespread use in the latter part of World War One.

The model V was primarily relegated to training as its performance was not competitive when compared to available French and British military reconnaissance aircraft.

After the war, LWF attempted to interest the United States Post Office in them as mailplanes, however the sole example doesn't appear to have ever carried the mail, and no orders were forthcoming.
