189:. Basic requirements involved the new gun to be "at least 25% more effective" than the 17-pdr. Initial focus was on development of a 55-pdr gun, although advancements in 17-pdr ammunition meant the advantages that would be secured by the 55-pdr were no longer as desirable, while the 55-pdr would suffer from considerable disadvantages such as the difficulties in the handling and stowage of ammunition. Other options considered included a 76 mm (3-inch) 17-pdr firing a 4 lb (1.8 kg)

During development, it was proposed that a 37 lb (17 kg) shot would give better performance, and this new design was trialled as the QF 37 pdr EX1 in June 1944. Following firing trials, the 37 lb shot was dropped for a 32 lb (15 kg) shot, and the gun was accepted as the QF
