ENGINEERING DIVISION (POMILIO) FVL-8
At the request of the US Army’s Engineering Division at McCook Field, Ottorino Pomilio of the Turin-based company of Pomilio Brothers undertook the design of a single-seat fighter around the then-new 280 hp Liberty eight-cylinder water-cooled engine. Designated FVL-8, the Pomilio-designed fighter was of wooden construction with plywood fuselage skinning and carried an armament of twin synchronised 0.3-in (7,7-mm) Vickers machine guns. Six prototypes of the FVL-8 were built in Indianapolis, the first of these being delivered in February 1919, but no series production was undertaken.

ENGINEERING DIVISION - POMILIO FVL-8 and BVL-12
Among the aeronautical talent sent to the United States by the allies in 1917/18 to help the aviation programme was the Italian designer Ottorino Pomilio, whose firm of Pomilio Brothers in Turin had been notably successful in the manufacture of two-seat observation and bomber models. At the request of the Engineering Division at McCook Field, Pomilio undertook the design of a single seat fighter, the FVL-8, around the new 280-h.p. Liberty 8-cylinder engine and a bomber, the BVL-12, designed around the later 400-h.p. 12-cylinder Liberty.
Both were of conventional all-wood construction, although the plywood fuselages were relatively new to American practice. The outstanding feature of both models was the location of the fuselage above the lower wing instead of on it. The FVL-8 radiator was in the centre section of the lower wing while the BVL-12 used a nose radiator. Six FVL-8s (40081/40086) and five BVL-12s (40087/40091) were built in Indianapolis, Indiana, but were not completed before the Armistice.
Data for the FVL-8 and the BVL-12 (in parentheses) follow: Span, 26 ft. 8 in. (45 ft. 3 in.); length, 21 ft. 8 in. (31 ft. 10 in.); wing area, 284 sq. ft. (621-5 sq. ft.); empty weight, 1,726 lb. (2,824 lb.); gross weight, 2,284 lb. (4,552 lb.); high speed, 133 m.p.h. (Ill m.p.h.).
