Short S.29 Sterling Mk I Series III
Mk I Series III
The Mk I Series III saw the final change to the Stirling’s defensive firepower. The provision for the side mounted guns was removed, and a Frazer Nash FN7A dorsal turret fitted to the top of the fuselage. A single manually operated machine gun could be attached to the hatch originally used by the dorsal turret. The Series III also saw an engine change, to the 1,500 hp Hercules XI engine. The Mk I Series III carried seven crew – two pilots, a navigator/ bomb aimer, a wireless operator, a flight engineer and two gunners, one less than the number of turrets. The vast majority of the 756 Stirling Mk Is were Series III aircraft.
