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

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.
 
The aircraft participated in the 1921 Aerial Derby, 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.

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