A radial engine with a single stage two-speed supercharger and epicyclic reduction gear. It is a development of the most famous Bristol sleeve-valve piston engine. During 1938–1966 130,000 Hercules engines of various versions were built. During World War II the Bristol Hercules engines powered the Bristol Beaufighter, Short Stirling, Short Sunderland, Saro Lerwick, Handley Page Halifax and Vickers Wellington aircraft.

The Hercules engines were also intended for the Polish bomber PZL 49.Miś (Bear) – the successor of the PZL.37 Łoś (Moose). In 1939 the purchase of the license was planned. After World War two the Hercules engines were license built in France and used in the Nord 2501 Noratlas transport aircraft. The Hercules 264 version was the powerplant of the Vickers Varsity Mk I transport aircraft. Similar 230, 232, 268, 736 i 762 versions powered the Handley Page Hastings/Hermes, Bristol Freighter, Short Solent and Vickers Valetta aircraft.
