The Ordnance QF 75 mm, abbreviated to OQF 75 mm, was a British tank gun of the Second World War. It was obtained by boring out the Ordnance QF 6-pounder ("6 pdr") 57 mm anti-tank gun to 75 mm, to give better performance against infantry targets similarly to the 75 mm M3 gun fitted to the American Sherman tank. The QF came from "quick-firing", referring to the use of ammunition where the shell has a fixed cartridge. The gun was also sometimes known as ROQF from Royal Ordnance (the manufacturer) Quick-Firing.
