The F.B.19 found more favour in Russia, where it was known as the "Vikkers Bullit". A single example was initially sent for evaluation in 1916. Leading pilots, including the ace Yevgraph Kruten, regarded it favourably. Russian sources indicate that it was fitted with a more powerful 130-hp Clerget engine that provided a maximum speed of around 200 km/h, making the "Bullit" faster than both the SPAD S.VII and the Sikorsky S-20. The Russians procured around twenty or thirty planes, and deployed at least four to front-line units, including one in which the ace Grigoriy Suk claimed two of his victories. A number of unarmed planes served as trainers.
