The QF 4-inch Mk XIX gun[2] was a British low-velocity 4-inch 40-calibre naval gun used to arm small warships such as Bathurst and Castle class corvettes and some River-class frigates in World War II, mainly against submarines.[3] It succeeded the more powerful World War I-era BL 4-inch Mk IX in this role, and its high-angle mounting added some anti-aircraft capability and allowed it to fire starshells to illuminate the battle area at night.
