"Bellona" had four single 20 mm added by April 1944, and received an extra eight single 20 mm by April 1945. (She was loaned to the RNZN after the war and operational 1946–52, the twin Oerlikons had been replaced by 6 single MK3P 40mm in the RNZN unique kiwi electric powered mount, but Bellona was never actually fitted with 6 standard tachymetric directors, requested by the RNZN for controlling the Bofors. The RNZN mothballed the quad pom pom mounts for manning reasons, but maintained the single oerlikons on HMNZS Bellona.).
