Austin-Ball A.F.B.1
Austin-Ball A.F.B.1 (Austin Fighting Biplane)
The A.F.B.1 was a British World War I fighter built by the Austin Motor Company, with design input from the famous ace Albert Ball. It was a single prototype and did not go into production.
Development and design
- Albert Ball, then the RFC’s most famous pilot, helped shape the project, but the main design work was done at Austins under C. H. Brooks.
- The prototype first flew on 27 July 1917. Only one aircraft was built, with the serial number B9909 (not visible in all photos).
What made it different
- It was a single-seat, all-metal-looking biplane with equal, unstaggered wings and no dihedral.
- The fuselage was unusually deep, with radiators on the sides and a cockpit that gave good forward visibility, though these radiators could interfere with view if damaged.
- Controls were operated by internal rods rather than external cables.
- Armament included two forward-firing Lewis guns: one fired through a hollow propeller shaft and the other on a mounting above the top wing’s center section. A third Lewis gun with additional ammunition was sometimes added on the center section.
Testing and fate
- Official flight testing took place at RAF Martlesham Heath. The A.F.B.1 had performance similar to the S.E.5a and climbed well, but it suffered from poor lateral (side-to-side) control.
- By this time the S.E.5a was already in production and Austins was busy with S.E.5a contracts and a shortage of Hispano-Suiza engines. This meant there was no production capacity for the A.F.B.1.
- A version with different wings (straight SPAD-type wings) appears in one photo, but its impact on performance isn’t clear.
- In October 1917, the engine was removed from the A.F.B.1 and sent away for use elsewhere. What happened to the aircraft after that is unknown.
Overall, the A.F.B.1 showed promise but never moved beyond the prototype due to production priorities and engine shortages shared with other fighters.
