The Bristol Aeroplane Company Type 32 Bullet was a biplane racing aircraft, built in 1919 to provide a flight test bed for the powerful Cosmos Jupiter (later the Bristol Jupiter) engine. It also acted as a high-speed demonstrator to publicise both the Bristol Engine Company and the engine itself.
 
A single example was built (G-EATS), which was flown for the first time in June 1920. In its initial form, the ailerons were fitted to the upper wings with a circular section wooden fuselage.
 
The Bristol Type 32 Bullet was entered in the Aerial Derby at Hendon on 24th July 1920, achieving an average speed of 129 mph.

After the race, the aircraft was re-configured with a larger diameter forward fuselage, which virtually enclosed the engine. At the same time, the forward fuselage was metal-clad and a large hemispherical spinner was fitted. Some sources give this variant the designation Type 32A.
 
In 1921, the wing area and gap were significantly reduced and it participated in the Aerial Derby of that year, being placed fourth at an average speed of 141.38 mph. In the final configuration, the ailerons were moved to the lower wings only and a pair of short centre-section cabane struts were fitted.

At its final Aerial Derby appearance the following year, the aircraft was placed second in the King's Cup Race at an average speed of 145 mph. This variant is sometimes described as the Bristol Type 32B.
 
The Bullet was eventually scrapped in 1924.
