Ammunition
The QF 75mm used US ammunition. The shells were "fixed" ammunition, the shell cartridge and projectile being proved together as a single complete round.
- Shell HE M46 with either the M48 or M54 fuze
- Bursting charge was 1.49 lb TNT or 1.36 lb 50/50 Amatol or 1.52 lb trimonite. The M48 fuze could be set for impact detonation ("Superquick") or delayed detonation; when in "Superquick" setting the delay would set the shell off if the impact didn't set off fuze. The M54 round had variable delay; the fuze starting burning at the instance of firing the round.
- Shot APC M61, with tracer in the base
- A armour-piercing capped projectile with a thin ballistic cap ("windshield") for better aerodynamics.
- Shot AP M72, with tracer in the base
- an entirely solid projectile
