The Vickers F.B.12 was a British single-seat biplane fighter aircraft designed and built by Vickers Limited during World War I. It first flew in 1916 and was primarily used for reconnaissance and fighter duties.

The Vickers F.B.12 was a two-bay biplane with a wooden structure and fabric covering. It was powered by a 100-horsepower Gnome Monosoupape rotary engine and had a top speed of around 96 miles per hour (154 kilometers per hour) and a ceiling of around 15,000 feet (4,600 meters). The aircraft was armed with a single synchronized Vickers machine gun mounted on the fuselage.

The F.B.12 was a popular aircraft among pilots, thanks to its good maneuverability, speed, and ease of handling. It was also relatively stable in flight, which made it a popular choice for reconnaissance duties.

In addition to its reconnaissance duties, the Vickers F.B.12 was also used as a fighter aircraft, and was flown by a number of British aces, including Albert Ball and Edward “Mick” Mannock. However, the aircraft was somewhat underpowered, which made it less effective in combat than some of its contemporaries.

Overall, the Vickers F.B.12 was an important fighter and reconnaissance aircraft of World War I, and helped establish the importance of reliable, easy-to-handle aircraft designs in the early years of aviation.
