The Bristol Blenheim was a light bomber that was used by Great Britain during World War II.
The Bristol Blenheim Mk I was fitted with two Mercury VIII engines that were capable of propelling it at speeds of up to 428 km/h, easily enough to outrun some of the early German fighters of the war. Furthermore, with an operational range of 2,340 kilometers and a service ceiling of 8,300 meters, the Blenheim was seen as the logical choice to base a night fighter off of as would come with the early Blenheim variants. However, the Mk I was limited by its armament of a single 7.7mm machine gun in the port wing, single machine gun in the rear turret, and bombload of 454 kilograms.
The total weight of the Blenheim was around 4,440 kilograms unloaded while its total length was 12.9 meters, and wingspan, 17.1 meters. In order to operate effectively, a crew of at least three men was required.
