Bristol 159
In March 1938 the Air Staff put together a paper that described an ideal bomber, and then a few months later specification B.19/38 was produced which indicated that the bomber would have a strong defensive armament of eight 20mm "shell-firing gun" (cannon) mounted in to turrets amidships, one above and one below the fuselage, to provide protection above, below and to the aircraft's rear. On 28 December B.19/38 was revised as B.1/39 and the new document, issued in March 1939, outlined a cruise speed of 451 km/h (280 mph), a minimum range flying at 4,572 m (15,000ft) with 4,082 kg (9,000 lb) of bombs aboard of 4,023 km (2,500 miles), and (at that time) a gross weight of 22,680 kg (50,000 lb). The aircraft was to replace all current heavy and medium bomber types, fabric was not to be used as a wing covering (in other words all Boulton Paul turrets, but in smaller streamlined Bristol-designed turrets).

The favoured powerplant was the Bristol Hercules Radial engine (the Rolls-Royce Griffon was an alternative) and the aircraft had a nosewheel undercarriage and eight internal fuel tanks which, for the 4,023 km(2,500 mile) range requirement, would hold 11,731 litres (2,580 gallons). The 159 could carry a further four fuel tanks on the bomb racks while the maximum estimated range was 5,632 km (3,500 miles) when flying at a speed of 451 km/h (280 mph). Wind tunnel tests with the design showed promise and indicated low drag and good stability, and by spring 1940 the process of structural design had reached an advanced stage.

Fate:
Mock-up dismantled in January 1941 due to great urgency by the outbreak of war.
